Subject: [PATCH 001/191] Fix behavior of absolute paths in .dockerignore

According to documentation (https://docs.docker.com/engine/reference/builder/#dockerignore-file), absolute paths like `/foo/bar` should have the same effect as `foo/bar`. This is not the case today.

This fix normalize paths when reading the .dockerignore file by removing
leading slashes.

Subject: [PATCH 002/191] devicemapper: remove thin pool if 'initDevmapper'
 failed

if initDevmapper failed after creating thin-pool, the thin-pool will not be removed,
this would cause we can't use the same lvm to create another thin-pool.

Subject: [PATCH 003/191] pkg: remove random package

The unnecessary `random` package has been removed in favor of using the
`math/rand` package directly. Seeding of the random value from crypto
has been added to the `stringid` package to account for the change.

May need to add an equivalent seed to `namesgenerator`, but this is
often used with `stringid` and has collision protection.

+### New feature: Long running session
+
+PR for [adding long-running session between daemon and cli](https://github.com/moby/moby/pull/32677) that enables advanced features like incremental context send, build credentials from the client, ssh forwarding etc. is ready for reviews. This is blocking many new features like token signing, not pulling unnecessary context files, exposing sources outside working directory etc.
+
+
+### Quality: Dependency interface switch
+
+Work continues on making the builder dependency interface more stable.
+
+Merged as part of this effort this week:
+
+- [Refactor COPY/ADD dispatchers](https://github.com/moby/moby/pull/33116)
+
+In review:
+- [Refactor builder probe cache and container backend](https://github.com/moby/moby/pull/33061)
+
+### Buildkit
+
+[Diff and snapshot services](https://github.com/containerd/containerd/pull/849) were added to containerd. This is a required dependency for [buildkit](https://github.com/moby/moby/issues/32925).
+
+### Proposals discussed in maintainers meeting
+
+New builder proposals were discussed in maintainers meeting. The decision was to give 2 more weeks for anyone to post feedback to [IMPORT/EXPORT commands](https://github.com/moby/moby/issues/32100) and [`RUN --mount`](https://github.com/moby/moby/issues/32507) and accept them for development if nothing significant comes up.
+
+Build secrets and its possible overlap with [--mount](https://github.com/moby/moby/issues/32507) was discussed as well. The decision was to create a [new issue](https://github.com/moby/moby/issues/33343)(as the [old PR](https://github.com/moby/moby/pull/30637) is closed) to track this and avoid it from blocking `--mount` implementation. 
+
+### Proposals for new Dockerfile features that need design feedback:
+
+[Add IMPORT/EXPORT commands to Dockerfile](https://github.com/moby/moby/issues/32100)
+
+[Add `DOCKEROS/DOCKERARCH` default ARG to Dockerfile](https://github.com/moby/moby/issues/32487)
+
+[Add support for `RUN --mount`](https://github.com/moby/moby/issues/32507)
+
+[DAG image builder](https://github.com/moby/moby/issues/32550)
+
+[Option to export the hash of the build context](https://github.com/moby/moby/issues/32963) (new)
+
+[Allow --cache-from=*](https://github.com/moby/moby/issues/33002#issuecomment-299041162) (new)
+
+If you are interested in implementing any of them, leave a comment on the specific issues.
+
+### Other new builder features currently in code-review:

Subject: [PATCH 006/191] cluster: Only pass a join address when in the process
 of joining a cluster

This code currently passes a random manager address when creating a new
Node. This doesn't really make sense - we should only pass a join
address on the initial join, or when retrying that join. An upcoming
change to swarmkit will pay attention to JoinAddr significant when a
node is already part of a cluster, so passing in the random value needs
to be avoided.

Subject: [PATCH 010/191] Don't create source directory while the daemon is
 being shutdown, fix #30348

If a container mount the socket the daemon is listening on into
container while the daemon is being shutdown, the socket will
not exist on the host, then daemon will assume it's a directory
and create it on the host, this will cause the daemon can't start
next time.

fix issue https://github.com/moby/moby/issues/30348

To reproduce this issue, you can add following code

```

step1 run a container which has `--restart always` and `-v /var/run/docker.sock:/sock`
```
$ docker run -ti --restart always -v /var/run/docker.sock:/sock busybox
/ #

```
step2 exit the the container
```
/ # exit
```
and kill the daemon when you see
```
===please stop the daemon===
```
in the daemon log

The daemon can't restart again and fail with `can't create unix socket /var/run/docker.sock: is a directory`.

Subject: [PATCH 016/191] Fix delete a image while saving it, delete
 successfully but failed to save it

Issue Description:
 * 1. Saving more than one images, `docker save -o a.tar aaa bbb`
 * 2. Delete the last image which in saving progress.  `docker rmi bbb`

Espected:
 Saving images operation shouldn't be disturbed. But the real result is that failed to
save image and get an error as below:
  `Error response from daemon: open
/var/lib/docker/image/devicemapper/imagedb/content/sha256/7c24e4d533a76e801662ad1b7e6e06bc1204f80110b5623e96ba2877c51479a1:
no such file or directory`

Analysis:
  1. While saving more than one images, it will get all the image info from reference/imagestore,
     and then using the `cached data` to save the images to a tar file.
  2. But this process doesn't have a resource lock, if a deletion operation comes, the image will be deleted,
     so saving operation will fail.

Solution:
 When begin to save an image, `Get` all the layers first. then the
deletion operation won't delete the layers.

Subject: [PATCH 018/191] Do not treat C.sysconf(C._SC_NPROCESSORS_ONLN)
 non-zero errno as error

Treat return code -1 as error instead.

People from glibc say that errno is undefined in case of successful
sysconf call according to POSIX standard:
Glibc bug: https://sourceware.org/bugzilla/show_bug.cgi?id=21536

More over in sysconf man it is wrongly said that "errno is not changed"
on success. So I've created a bug to man-pages:
https://bugzilla.kernel.org/show_bug.cgi?id=195955

Background: Glibc's sysconf(_SC_NPROCESSORS_ONLN) changes errno to
ENOENT, if there is no /sys/devices/system/cpu/online file, while
the call itself is successful. In Virtuozzo containers we prohibit
most of sysfs files for security reasons. So we have Run():daemon
/stats/collector.go infinitely loop never actualy collecting stats
from publisher pairs.

v2: add comment

+# Development Report for May 29, 2017
+
+### New feature: Long running session
+
+PR for [adding long-running session between daemon and cli](https://github.com/moby/moby/pull/32677) that enables advanced features like incremental context send, build credentials from the client, ssh forwarding, etc. is ready for reviews. It is blocking many new features like the token signing, not pulling unnecessary context files, exposing sources outside working directory, etc. Maintainers are encouraged to give this one a review!
+
+
+### Quality: Dependency interface switch
+
+Work continues on making the builder dependency interface more stable.
+
+Merged as part of this effort this week:
+
+- [Refactor builder probe cache and container backend](https://github.com/moby/moby/pull/33061)
+
+@dnephin continues working on the copy/export aspects of the interface.
+
+### Buildkit
+
+Some initial proof of concept code for [buildkit](https://github.com/moby/moby/issues/32925) has been pushed to https://github.com/tonistiigi/buildkit_poc . It's in a very early exploratory stage. Current development has been about providing concurrent references based access to the snapshot data that is backed by containerd. More info should follow in next weeks, including hopefully opening up an official repo. If you have questions or want to help, stop by the issues section of that repo or the proposal in moby/moby.
+
+### Proposals discussed in maintainers meeting
+
+Reminder from last week: New builder proposals were discussed in maintainers meeting. The decision was to give 2 more weeks for anyone to post feedback to [IMPORT/EXPORT commands](https://github.com/moby/moby/issues/32100) and [`RUN --mount`](https://github.com/moby/moby/issues/32507) and accept them for development if nothing significant comes up.
+
+New issue about [build secrets](https://github.com/moby/moby/issues/33343) has not got much traction. If you want this feature to become a reality please make yourself heard.
+
+### Proposals for new Dockerfile features that need design feedback:
+
+[Add IMPORT/EXPORT commands to Dockerfile](https://github.com/moby/moby/issues/32100)
+
+[Add `DOCKEROS/DOCKERARCH` default ARG to Dockerfile](https://github.com/moby/moby/issues/32487)
+
+[Add support for `RUN --mount`](https://github.com/moby/moby/issues/32507)
+
+[DAG image builder](https://github.com/moby/moby/issues/32550)
+
+[Option to export the hash of the build context](https://github.com/moby/moby/issues/32963) (new)
+
+[Allow --cache-from=*](https://github.com/moby/moby/issues/33002#issuecomment-299041162) (new)
+
+If you are interested in implementing any of them, leave a comment on the specific issues.
+
+### Other new builder features currently in code-review:
+
+[Fix canceling builder on chunked requests](https://github.com/moby/moby/pull/33363)
+
+[Fix parser directive refactoring](https://github.com/moby/moby/pull/33436)
+
+[Warn/deprecate continuing on empty lines in `Dockerfile`](https://github.com/moby/moby/pull/29161)
+
+[Fix behavior of absolute paths in .dockerignore](https://github.com/moby/moby/pull/32088)

Subject: [PATCH 021/191] Remove `cli/flags` package
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Moving the `common*.go` files in `cmd/dockerd` directly (it's the
  only place it's getting used)
- Rename `cli/flags` to `cli/config` because it's the only thing left
  in that package 👼

Now, `integration-cli` does *truly* not depend on `cobra` stuff.

Subject: [PATCH 025/191] Remove btrfs quota groups after containers destroyed

This fix tries to address the issue raised in 29325 where
btrfs quota groups are not clean up even after containers
have been destroyed.

The reason for the issue is that btrfs quota groups have
to be explicitly destroyed. This fix fixes this issue.

This fix is tested manually in Ubuntu 16.04,
with steps specified in 29325.

This fix fixes 29325.

Subject: [PATCH 026/191] Persist the quota size for btrfs so that daemon
 restart keeps quota

This commit is an extension of fix for 29325 based on the review comment.
In this commit, the quota size for btrfs is kept in `/var/lib/docker/btrfs/quotas`
so that a daemon restart keeps quota.

Subject: [PATCH 027/191] Limit max backoff delay to 2 seconds for GRPC
 connection

Docker use default GRPC backoff strategy to reconnect to containerd when
connection is lost. and the delay time grows exponentially, until reaches 120s.

So Change the max delay time to 2s to avoid docker and containerd
connection failure.

+# Development Report for June 5, 2017
+
+### New feature: Long running session
+
+Similarly to last week, the PR for [adding long-running session between daemon and cli](https://github.com/moby/moby/pull/32677) is waiting for reviews.  It is blocking many new features like the token signing, not pulling unnecessary context files, exposing sources outside working directory, etc. Maintainers are encouraged to give this one a review so it can be included in `v17.07` release.
+
+
+### Quality: Dependency interface switch
+
+Work continues on making the builder dependency interface more stable.
+
+PRs currently in review as part of this effort:
+
+- [Move file copying from the daemon to the builder](https://github.com/moby/moby/pull/33454)
+
+This PR is the core of the update that removes the need to track active containers and instead of lets builder hold references to layers while it's running.
+
+Related to this, @simonferquel opened a [WIP PR](https://github.com/moby/moby/pull/33492) that introduces typed Dockerfile parsing. This enables making [decisions about dependencies](https://github.com/moby/moby/issues/32550#issuecomment-297867334) between build stages and reusing Dockerfile parsing as a buildkit frontend.
+
+### Buildkit
+
+Some initial proof of concept code for [buildkit](https://github.com/moby/moby/issues/32925) has been pushed to https://github.com/tonistiigi/buildkit_poc . It's in a very early exploratory stage. Current codebase includes libraries for getting concurrency safe references to containerd snapshots using a centralized cache management instance. There is a sample source implementation for pulling images to these snapshots and executing jobs with runc on top of them. There is also some utility code for concurrent execution and progress stream handling. More info should follow in next weeks, including hopefully opening up an official repo. If you have questions or want to help, stop by the issues section of that repo or the proposal in moby/moby.
+
+### `v17.06` release
+
+Some bugs [1](https://github.com/moby/moby/issues/33493), [2](https://github.com/moby/moby/pull/33524) were found with the `ONBUILD` instruction in `v17.06-rc1`. They should be fixed in `rc2`. As quite a lot has changed in the builder internals, users are recommended to test the release candidate.
+
+### Proposals discussed in maintainers meeting
+
+Reminder from last week: New builder proposals were discussed in maintainers meeting. The decision was to give two more weeks for anyone to post feedback to [IMPORT/EXPORT commands](https://github.com/moby/moby/issues/32100) and [`RUN --mount`](https://github.com/moby/moby/issues/32507) and accept them for development if nothing significant comes up. It is the last week to post your feedback on these proposals or the comments in them. You can also volunteer to implement them.
+
+A new issue about [build secrets](https://github.com/moby/moby/issues/33343) has not got much traction. If you want this feature to become a reality, please make yourself heard.
+
+### Proposals for new Dockerfile features that need design feedback:
+
+[Add IMPORT/EXPORT commands to Dockerfile](https://github.com/moby/moby/issues/32100)
+
+[Add `DOCKEROS/DOCKERARCH` default ARG to Dockerfile](https://github.com/moby/moby/issues/32487)
+
+[Add support for `RUN --mount`](https://github.com/moby/moby/issues/32507)
+
+[DAG image builder](https://github.com/moby/moby/issues/32550)
+
+[Option to export the hash of the build context](https://github.com/moby/moby/issues/32963) (new)
+
+[Allow --cache-from=*](https://github.com/moby/moby/issues/33002#issuecomment-299041162) (new)
+
+[Provide advanced .dockeringore use-cases](https://github.com/moby/moby/issues/12886) [2](https://github.com/moby/moby/issues/12886#issuecomment-306247989)
+
+If you are interested in implementing any of them, leave a comment on the specific issues.
+
+### Other builder PRs merged last week
+
+[Fix canceling builder on chunked requests](https://github.com/moby/moby/pull/33363)
+
+[Fix parser directive refactoring](https://github.com/moby/moby/pull/33436)
+
+### Builder features currently in code-review:
+
+[Warn/deprecate continuing on empty lines in `Dockerfile`](https://github.com/moby/moby/pull/29161)
+
+[Fix behavior of absolute paths in .dockerignore](https://github.com/moby/moby/pull/32088)

+# Development Report for June 5, 2017
+
+## Daily Meeting
+
+A daily meeting is hosted on [slack](https://dockercommunity.slack.com) every business day at 9am PST on the channel `#moby-project`.
+Lots of discussion happened during this meeting to kickstart the project, but now that we have the forums, we see less activity there.
+We are discussing the future of this meeting [here](https://forums.mobyproject.org/t/of-standups-future), we will possibily move the meeting
+to weekly.
+
+## Topics discussed last week
+
+### The CLI split
+
+Thanks to @tiborvass, the man pages, docs and completion scripts were imported to `github.com/docker/cli` [last week](https://github.com/docker/cli/pull/147)
+Once everything is finalised, we will remove them from `github.com/moby/moby`
+
+### Find a good and non-confusing home for the remaining monolith
+
+Discussion on this topic is still ongoing, and possible approaches are looked into. The active discussion has moved
+from GitHub to [https://forums.mobyproject.org/](https://forums.mobyproject.org/t/topic-find-a-good-an-non-confusing-home-for-the-remaining-monolith)
+
+
+### Find a place for `/pkg`
+
+Thanks to @dnephin this topic in on-going, you can follow progress [here](https://github.com/moby/moby/issues/32989)
+Many pkgs were reorganised last week, and more to come this week.
+
+
+### Builder
+
+The builder dev report can be found [here](builder/2017-06-05.md)
+
+
+### LinuxKit
+
+The LinuxKit dev report can be found [here](https://github.com/linuxkit/linuxkit/blob/master/reports/2017-06-03.md)

 Some initial proof of concept code for [buildkit](https://github.com/moby/moby/issues/32925) has been pushed to https://github.com/tonistiigi/buildkit_poc . It's in a very early exploratory stage. Current codebase includes libraries for getting concurrency safe references to containerd snapshots using a centralized cache management instance. There is a sample source implementation for pulling images to these snapshots and executing jobs with runc on top of them. There is also some utility code for concurrent execution and progress stream handling. More info should follow in next weeks, including hopefully opening up an official repo. If you have questions or want to help, stop by the issues section of that repo or the proposal in moby/moby.
 
-### `v17.06` release
-
-Some bugs [1](https://github.com/moby/moby/issues/33493), [2](https://github.com/moby/moby/pull/33524) were found with the `ONBUILD` instruction in `v17.06-rc1`. They should be fixed in `rc2`. As quite a lot has changed in the builder internals, users are recommended to test the release candidate.
-
 ### Proposals discussed in maintainers meeting
 
 Reminder from last week: New builder proposals were discussed in maintainers meeting. The decision was to give two more weeks for anyone to post feedback to [IMPORT/EXPORT commands](https://github.com/moby/moby/issues/32100) and [`RUN --mount`](https://github.com/moby/moby/issues/32507) and accept them for development if nothing significant comes up. It is the last week to post your feedback on these proposals or the comments in them. You can also volunteer to implement them.

Subject: [PATCH 052/191] Fix vfs unit test and port VFS to the new IDMappings

The test was failing because TarOptions was using a non-pointer for
ChownOpts, which meant the check for nil was never true, and
createTarFile was never using the hdr.UID/GID

Subject: [PATCH 055/191] Remove error return from RootPair

Subject: [PATCH 056/191] Service alias should not be copied to task alias

If a service alias is copied to task, then the DNS resolution on the
service name will resolve to service VIP and all of Task-IPs and that
will break the concept of vip based load-balancing resulting in all the
dns-rr caching issues.

This is a regression introduced in #33130

Subject: [PATCH 057/191] Revert ONCLR and OPOST changes

This reverts to a version of runc without the ONCLR cleared to not cause
a regression with different clients using --tty.

This also reverts the OPOST changes to the term package to support the
initial change.

Subject: [PATCH 062/191] Update grpc to v1.3.0 and bump protobuf bindings.

and update some dependent packages.

We would like to keep moby/moby and swarmkit somewhat in sync here and
https://github.com/docker/swarmkit/pull/2229 proposes a similar bump to
swarmkit, needed due to https://github.com/docker/swarmkit/pull/1965 which
pulls in containerd which uses some newer features of the grpc package.

Subject: [PATCH 065/191] Fix copy when used with scratch and images with empty
 RootFS

Commit the rwLayer to get the correct DiffID
Refacator copy in thebuilder
move more code into exportImage
cleanup some windows tests
Release the newly commited layer.
Set the imageID on the buildStage after exporting a new image.
Move archiver to BuildManager.
Have ReleaseableLayer.Commit return a layer
and store the Image from exportImage in the local imageSources cache
Remove NewChild from image interface.

Subject: [PATCH 066/191] daemon: Remove daemon datastructure dump
 functionality

When sending SIGUSR1 to the daemon, it can crash because of a concurrent
map access panic, showing a stack trace involving dumpDaemon. It appears
it's not possible to recover from a concurrent map access panic. Since
it's important that SIGUSR1 not be a destructive operation, sadly the
best course of action I can think of is to remove this functionality.

+
+These parameters always set an upper limit on the memory available to the container. On Linux, this

+

Subject: [PATCH 079/191] Bump API version

With the Moby/Docker split, no decisions have been
made yet how, and when to bump the API version.

Although these decisions should not be lead
by Docker releases, I'm bumping the API version
to not complicate things for now; after this bump
we should make a plan how to handle this in future
(for example, using SemVer for the REST api, and
bump with every change).

Subject: [PATCH 084/191] container/stream/attach: use pools.Copy

The use of pools.Copy avoids io.Copy's internal buffer allocation.
This commit replaces io.Copy with pools.Copy to avoid the allocation of
buffers in io.Copy.

Subject: [PATCH 085/191] Fix missing "--version" argument

Commit 858b4b44c8172eb2c92767c8f624f4138db5212b added
support for obtaining the runtime version
if a custom path was set, but accidentally
removed the "--version" flag.

This patch restores the flag, and adds an integration
test to verify the behavior..

Subject: [PATCH 088/191] Disable legacy (v1) registries by default

Deprecation of interacting with v1 registries was
started in docker 1.8.3, which added a `--disable-legacy-registry`
flag.

This option was anounced to be the default starting
with docker 17.06, and v1 registries completely
removed in docker 17.12.

This patch updates the default, and disables
interaction with v1 registres by default.

Subject: [PATCH 092/191] Add `scope` filter in `/networks/<id>`

This fix tries to add a `scope` in the query of `/networks/<id>`
(`NetworkInspect`) so that in case of duplicate network names,
it is possible to locate the network ID based on the network
scope (`local`, 'swarm', or `global`).

Multiple networks might exist in different scopes, which is a legitimate case.
For example, a network name `foo` might exists locally and in swarm network.

However, before this PR it was not possible to query a network name `foo`
in a specific scope like swarm.

This fix fixes the issue by allowing a `scope` query in `/networks/<id>`.

Additional test cases have been added to unit tests and integration tests.

This fix is related to docker/cli#167, moby/moby#30897, moby/moby#33561, moby/moby#30242

This fix fixes docker/cli#167

Subject: [PATCH 093/191] plugin/store.Get: return a specific error if plugin
 is disabled

Previously, a 'plugin not found' error would be returned if a plugin to be
retrieved was found but disabled. This was misleading and incorrect. Now,
a new error plugin.ErrDisabled is returned in this case. This makes the
error message when trying to statically start plugins (from daemon.json or
dockerd command line) accurate.

From f3ddace46876373f481fbbd4be24d3227b5567b9 Mon Sep 17 00:00:00 2001
From: Sebastiaan van Stijn <github@gone.nl>
Date: Mon, 12 Jun 2017 14:47:27 +0200
Subject: [PATCH 096/191] Use tempdir instead of working directory as
 build-context

The `makefile()` utility was used to create a temporary Dockerfile, and after
tests completed, this file was deleted.

However, the _build_ used the current path (`/usr/local/bin/docker`) as
build-context. As a result, roughtly 20 MB was sent as build-context for each
build, but none of the builds actually required a build-context.

This patch;

- creates a temp-dir for the test, which can be used as build-context
- changes the `makefile()` utility and removes the `cleanup` functionality
- instead, the `temp-dir` is removed after the test finishes (which also removes the temporary `Dockerfile`)

Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

Subject: [PATCH 097/191] Simplify
 DockerRegistrySuite.TestUserAgentPassThrough()

This patch simplifies the test by;

- re-using the registry-mock / handler
- skipping the last `docker build`, which was only
  used to make sure a local image was present. Instead,
  the daemon is started with a `busybox` image loaded.

Also added a comment, explaining why the mock always
returns a 404 (hence, error/output-string should not
be checked in the test), and made the mock return a
valid/correctly formatted error response.

+# Development Report for June 12, 2017
+
+
+### Buildkit
+
+[Proposal](https://github.com/moby/moby/issues/32925)
+
+More updates to the [POC repo](https://github.com/tonistiigi/buildkit_poc). It now contains binaries for the daemon and client. Examples directory shows a way for invoking a build job by generating the internal low-level build graph definition with a helper binary(as there is not support for frontends yet). The grpc control server binary can be built in two versions, one that connects to containerD socket and other that doesn't have any external dependencies.
+
+If you have questions or want to help, stop by the issues section of that repo or the proposal in moby/moby.
+
+### Typed Dockerfile parsing
+
+[PR](https://github.com/moby/moby/pull/33492)
+
+New PR that enables parsing Dockerfiles into typed structures so they can be preprocessed to eliminate unnecessary build stages and reused with different kinds of dispatchers.
+
+### Long running session & incremental file sending
+
+[PR ](https://github.com/moby/moby/pull/32677) 
+
+Same status as last week. The PR went through one pass of review from @dnephin and has been rebased again. Maintainers are encouraged to give this one a review so it can be included in `v17.07` release.
+
+
+### Quality: Dependency interface switch
+
+[Move file copying from the daemon to the builder](https://github.com/moby/moby/pull/33454) PR is waiting for a second review. 
+
+### Proposals for new Dockerfile features that need design feedback:
+
+[Add IMPORT/EXPORT commands to Dockerfile](https://github.com/moby/moby/issues/32100)
+
+[Add `DOCKEROS/DOCKERARCH` default ARG to Dockerfile](https://github.com/moby/moby/issues/32487)
+
+[Add support for `RUN --mount`](https://github.com/moby/moby/issues/32507)
+
+[DAG image builder](https://github.com/moby/moby/issues/32550)
+
+[Option to export the hash of the build context](https://github.com/moby/moby/issues/32963) (new)
+
+[Allow --cache-from=*](https://github.com/moby/moby/issues/33002#issuecomment-299041162) (new)
+
+[Provide advanced .dockeringore use-cases](https://github.com/moby/moby/issues/12886) [2](https://github.com/moby/moby/issues/12886#issuecomment-306247989)
+
+If you are interested in implementing any of them, leave a comment on the specific issues.
+
+### Other builder PRs merged last week
+
+
+### Builder features currently in code-review:
+
+[Warn/deprecate continuing on empty lines in `Dockerfile`](https://github.com/moby/moby/pull/29161)
+
+[Fix behavior of absolute paths in .dockerignore](https://github.com/moby/moby/pull/32088)
+
+### Backlog
+
+[Build secrets](https://github.com/moby/moby/issues/33343) has not got much traction. If you want this feature to become a reality, please make yourself heard.

Subject: [PATCH 101/191] Ignore HNS networks with type Private

Fix #33052 (workaround style)

**- What I did**

HNS reports networks that don't have anything to do with the Daemon, and
for which no networking plugin is available. This make the Daemon start
sequence pause for 15 secs, as the plugin resolving logic has a wait &
retry logic

**- How I did it**

Just after retrieving the HNS networks, I filter out those with type
`Private`

**- How to verify it**

Replace dockerd coming with Docker for Windows from one built from this
PR. Windows containers daemon should now launch pretty quickly

Subject: [PATCH 102/191] Make TestServiceCreateCompatiblePlatforms use actual
 API response

The `TestServiceCreateCompatiblePlatforms()` test was confusing, because it
did not actually use the mocked API response, but used a local
`distributionInspectBody` variable to verify that the `/distribution/` endpoint
was called.

This flow was especially confusing, because a comment in the test describes;

    "check if the /distribution endpoint returned correct output"

If (for whatever reason), the endpoint was not called, the test would panic,
because the `distributionInspectBody` would not be set.

This patch rewrites the test to use the actual API response that is returned
by the mock, and verifies that the information returned by the `/distribution/`
endpoint is properly used in the service's definition.

Also, this removes the use of a questionable golang range feature which
corrects for mutation of a slice during iteration over that slice. This
makes the filter operation easier to read and reason about.

+# Development Report for June 12, 2017
+
+## Moby Summit
+
+The next Moby Summit will be at Docker HQ on June 19th, register [here](https://www.eventbrite.com/e/moby-summit-tickets-34483396768)
+
+## Daily Meeting
+
+### The CLI split
+
+Manpages and docs yaml files can now be generated on [docker/cli](https://github.com/docker/cli).
+Man pages, docs and completion scripts will be removed next week thanks to @tiborvass 
+
+### Find a good and non-confusing home for the remaining monolith
+
+Lot's of dicussion happened on the [forums](https://forums.mobyproject.org/t/topic-find-a-good-an-non-confusing-home-for-the-remaining-monolith)
+We should expect to do those changes after the moby summit. We contacted github to work with them so we have a smooth move.
+
+### Moby tool
+
+`moby` tool docs were moved from [LinuxKit](https://github.com/linuxkit/linuxkit) to the [moby tool repo](https://github.com/moby/tool) thanks to @justincormack
+
+### Custom golang URLs
+
+More discussions on the [forums]https://forums.mobyproject.org/t/cutoms-golang-urls), no agreement for now.
+
+### Buildkit
+
+[Proposal](https://github.com/moby/moby/issues/32925)
+
+More updates to the [POC repo](https://github.com/tonistiigi/buildkit_poc). It now contains binaries for the daemon and client. Examples directory shows a way for invoking a build job by generating the internal low-level build graph definition with a helper binary(as there is not support for frontends yet). The grpc control server binary can be built in two versions, one that connects to containerD socket and other that doesn't have any external dependencies.
+
+If you have questions or want to help, stop by the issues section of that repo or the proposal in moby/moby.
+
+#### Typed Dockerfile parsing
+
+[PR](https://github.com/moby/moby/pull/33492)
+
+New PR that enables parsing Dockerfiles into typed structures so they can be preprocessed to eliminate unnecessary build stages and reused with different kinds of dispatchers.
+
+#### Long running session & incremental file sending
+
+[PR ](https://github.com/moby/moby/pull/32677) 
+
+Same status as last week. The PR went through one pass of review from @dnephin and has been rebased again. Maintainers are encouraged to give this one a review so it can be included in `v17.07` release.
+
+
+#### Quality: Dependency interface switch
+
+[Move file copying from the daemon to the builder](https://github.com/moby/moby/pull/33454) PR is waiting for a second review. 
+
+#### Proposals for new Dockerfile features that need design feedback:
+
+[Add IMPORT/EXPORT commands to Dockerfile](https://github.com/moby/moby/issues/32100)
+
+[Add `DOCKEROS/DOCKERARCH` default ARG to Dockerfile](https://github.com/moby/moby/issues/32487)
+
+[Add support for `RUN --mount`](https://github.com/moby/moby/issues/32507)
+
+[DAG image builder](https://github.com/moby/moby/issues/32550)
+
+[Option to export the hash of the build context](https://github.com/moby/moby/issues/32963) (new)
+
+[Allow --cache-from=*](https://github.com/moby/moby/issues/33002#issuecomment-299041162) (new)
+
+[Provide advanced .dockeringore use-cases](https://github.com/moby/moby/issues/12886) [2](https://github.com/moby/moby/issues/12886#issuecomment-306247989)
+
+If you are interested in implementing any of them, leave a comment on the specific issues.
+
+#### Builder features currently in code-review:
+
+[Warn/deprecate continuing on empty lines in `Dockerfile`](https://github.com/moby/moby/pull/29161)
+
+[Fix behavior of absolute paths in .dockerignore](https://github.com/moby/moby/pull/32088)
+
+#### Backlog
+
+[Build secrets](https://github.com/moby/moby/issues/33343) has not got much traction. If you want this feature to become a reality, please make yourself heard.

-#!/usr/bin/env bash
-#
-# bash completion file for core docker commands
-#
-# This script provides completion of:
-#  - commands and their options
-#  - container ids and names
-#  - image repos and tags
-#  - filepaths
-#
-# To enable the completions either:
-#  - place this file in /etc/bash_completion.d
-#  or
-#  - copy this file to e.g. ~/.docker-completion.sh and add the line
-#    below to your .bashrc after bash completion features are loaded
-#    . ~/.docker-completion.sh
-#
-# Configuration:
-#
-# For several commands, the amount of completions can be configured by
-# setting environment variables.
-#
-# DOCKER_COMPLETION_SHOW_CONTAINER_IDS
-# DOCKER_COMPLETION_SHOW_NETWORK_IDS
-# DOCKER_COMPLETION_SHOW_NODE_IDS
-# DOCKER_COMPLETION_SHOW_PLUGIN_IDS
-# DOCKER_COMPLETION_SHOW_SECRET_IDS
-# DOCKER_COMPLETION_SHOW_SERVICE_IDS
-#   "no"  - Show names only (default)
-#   "yes" - Show names and ids
-#
-# You can tailor completion for the "events", "history", "inspect", "run",
-# "rmi" and "save" commands by settings the following environment
-# variables:
-#
-# DOCKER_COMPLETION_SHOW_IMAGE_IDS
-#   "none" - Show names only (default)
-#   "non-intermediate" - Show names and ids, but omit intermediate image IDs
-#   "all" - Show names and ids, including intermediate image IDs
-#
-# DOCKER_COMPLETION_SHOW_TAGS
-#   "yes" - include tags in completion options (default)
-#   "no"  - don't include tags in completion options
-
-#
-# Note:
-# Currently, the completions will not work if the docker daemon is not
-# bound to the default communication port/socket
-# If the docker daemon is using a unix socket for communication your user
-# must have access to the socket for the completions to function correctly
-#
-# Note for developers:
-# Please arrange options sorted alphabetically by long name with the short
-# options immediately following their corresponding long form.
-# This order should be applied to lists, alternatives and code blocks.

-# Deprecated Engine Features
-
-The following list of features are deprecated in Engine.
-To learn more about Docker Engine's deprecation policy,
-see [Feature Deprecation Policy](https://docs.docker.com/engine/#feature-deprecation-policy).
-
-### Asynchronous `service create` and `service update`
-
-**Deprecated In Release: v17.05.0**
-
-**Disabled by default in release: v17.09**
-
-Docker 17.05.0 added an optional `--detach=false` option to make the
-`docker service create` and `docker service update` work synchronously. This
-option will be enable by default in Docker 17.09, at which point the `--detach`
-flag can be used to use the previous (asynchronous) behavior.
-
-### `-g` and `--graph` flags on `dockerd`
-
-**Deprecated In Release: v17.05.0**
-
-The `-g` or `--graph` flag for the `dockerd` or `docker daemon` command was
-used to indicate the directory in which to store persistent data and resource
-configuration and has been replaced with the more descriptive `--data-root`
-flag.
-
-These flags were added before Docker 1.0, so will not be _removed_, only
-_hidden_, to discourage their use.
-
-### Top-level network properties in NetworkSettings
-
-**Deprecated In Release: [v1.13.0](https://github.com/docker/docker/releases/tag/v1.13.0)**
-
-**Target For Removal In Release: v17.12**
-
-When inspecting a container, `NetworkSettings` contains top-level information
-about the default ("bridge") network;
-
-`EndpointID`, `Gateway`, `GlobalIPv6Address`, `GlobalIPv6PrefixLen`, `IPAddress`,
-`IPPrefixLen`, `IPv6Gateway`, and `MacAddress`.
-
-These properties are deprecated in favor of per-network properties in
-`NetworkSettings.Networks`. These properties were already "deprecated" in
-docker 1.9, but kept around for backward compatibility.
-
-Refer to [#17538](https://github.com/docker/docker/pull/17538) for further
-information.
-
-### `filter` param for `/images/json` endpoint
-**Deprecated In Release: [v1.13.0](https://github.com/docker/docker/releases/tag/v1.13.0)**
-
-**Target For Removal In Release: v17.12**
-
-The `filter` param to filter the list of image by reference (name or name:tag) is now implemented as a regular filter, named `reference`.
-
-### `repository:shortid` image references
-**Deprecated In Release: [v1.13.0](https://github.com/docker/docker/releases/tag/v1.13.0)**
-
-**Target For Removal In Release: v17.12**
-
-`repository:shortid` syntax for referencing images is very little used, collides with tag references can be confused with digest references.
-
-### `docker daemon` subcommand
-**Deprecated In Release: [v1.13.0](https://github.com/docker/docker/releases/tag/v1.13.0)**
-
-**Target For Removal In Release: v17.12**
-
-The daemon is moved to a separate binary (`dockerd`), and should be used instead.
-
-### Duplicate keys with conflicting values in engine labels
-**Deprecated In Release: [v1.13.0](https://github.com/docker/docker/releases/tag/v1.13.0)**
-
-**Target For Removal In Release: v17.12**
-
-Duplicate keys with conflicting values have been deprecated. A warning is displayed
-in the output, and an error will be returned in the future.
-
-### `MAINTAINER` in Dockerfile
-**Deprecated In Release: [v1.13.0](https://github.com/docker/docker/releases/tag/v1.13.0)**
-
-`MAINTAINER` was an early very limited form of `LABEL` which should be used instead.
-
-### API calls without a version
-**Deprecated In Release: [v1.13.0](https://github.com/docker/docker/releases/tag/v1.13.0)**
-
-**Target For Removal In Release: v17.12**
-
-API versions should be supplied to all API calls to ensure compatibility with
-future Engine versions. Instead of just requesting, for example, the URL
-`/containers/json`, you must now request `/v1.25/containers/json`.
-
-### Backing filesystem without `d_type` support for overlay/overlay2
-**Deprecated In Release: [v1.13.0](https://github.com/docker/docker/releases/tag/v1.13.0)**
-
-**Target For Removal In Release: v17.12**
-
-The overlay and overlay2 storage driver does not work as expected if the backing
-filesystem does not support `d_type`. For example, XFS does not support `d_type`
-if it is formatted with the `ftype=0` option.
-
-Please also refer to [#27358](https://github.com/docker/docker/issues/27358) for
-further information.
-
-### Three arguments form in `docker import`
-**Deprecated In Release: [v0.6.7](https://github.com/docker/docker/releases/tag/v0.6.7)**
-
-**Removed In Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)**
-
-The `docker import` command format `file|URL|- [REPOSITORY [TAG]]` is deprecated since November 2013. It's no more supported.
-
-### `-h` shorthand for `--help`
-
-**Deprecated In Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)**
-
-**Target For Removal In Release: v17.09**
-
-The shorthand (`-h`) is less common than `--help` on Linux and cannot be used
-on all subcommands (due to it conflicting with, e.g. `-h` / `--hostname` on
-`docker create`). For this reason, the `-h` shorthand was not printed in the
-"usage" output of subcommands, nor documented, and is now marked "deprecated".
-
-### `-e` and `--email` flags on `docker login`
-**Deprecated In Release: [v1.11.0](https://github.com/docker/docker/releases/tag/v1.11.0)**
-
-**Removed In Release: [v17.06](https://github.com/docker/docker-ce/releases/tag/v17.06.0-ce)**
-
-The docker login command is removing the ability to automatically register for an account with the target registry if the given username doesn't exist. Due to this change, the email flag is no longer required, and will be deprecated.
-
-### Separator (`:`) of `--security-opt` flag on `docker run`
-**Deprecated In Release: [v1.11.0](https://github.com/docker/docker/releases/tag/v1.11.0)**
-
-**Target For Removal In Release: v17.06**
-
-The flag `--security-opt` doesn't use the colon separator(`:`) anymore to divide keys and values, it uses the equal symbol(`=`) for consistency with other similar flags, like `--storage-opt`.
-
-### `/containers/(id or name)/copy` endpoint
-
-**Deprecated In Release: [v1.8.0](https://github.com/docker/docker/releases/tag/v1.8.0)**
-
-**Removed In Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)**
-
-The endpoint `/containers/(id or name)/copy` is deprecated in favor of `/containers/(id or name)/archive`.
-
-### Ambiguous event fields in API
-**Deprecated In Release: [v1.10.0](https://github.com/docker/docker/releases/tag/v1.10.0)**
-
-The fields `ID`, `Status` and `From` in the events API have been deprecated in favor of a more rich structure.
-See the events API documentation for the new format.
-
-### `-f` flag on `docker tag`
-**Deprecated In Release: [v1.10.0](https://github.com/docker/docker/releases/tag/v1.10.0)**
-
-**Removed In Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)**
-
-To make tagging consistent across the various `docker` commands, the `-f` flag on the `docker tag` command is deprecated. It is not longer necessary to specify `-f` to move a tag from one image to another. Nor will `docker` generate an error if the `-f` flag is missing and the specified tag is already in use.
-
-### HostConfig at API container start
-**Deprecated In Release: [v1.10.0](https://github.com/docker/docker/releases/tag/v1.10.0)**
-
-**Removed In Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)**
-
-Passing an `HostConfig` to `POST /containers/{name}/start` is deprecated in favor of
-defining it at container creation (`POST /containers/create`).
-
-### `--before` and `--since` flags on `docker ps`
-
-**Deprecated In Release: [v1.10.0](https://github.com/docker/docker/releases/tag/v1.10.0)**
-
-**Removed In Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)**
-
-The `docker ps --before` and `docker ps --since` options are deprecated.
-Use `docker ps --filter=before=...` and `docker ps --filter=since=...` instead.
-
-### `--automated` and `--stars` flags on `docker search`
-
-**Deprecated in Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)**
-
-**Target For Removal In Release: v17.09**
-
-The `docker search --automated` and `docker search --stars` options are deprecated.
-Use `docker search --filter=is-automated=...` and `docker search --filter=stars=...` instead.
-
-### Driver Specific Log Tags
-**Deprecated In Release: [v1.9.0](https://github.com/docker/docker/releases/tag/v1.9.0)**
-
-**Removed In Release: [v1.12.0](https://github.com/docker/docker/releases/tag/v1.12.0)**
-
-Log tags are now generated in a standard way across different logging drivers.
-Because of which, the driver specific log tag options `syslog-tag`, `gelf-tag` and
-`fluentd-tag` have been deprecated in favor of the generic `tag` option.
-
-```bash
-{% raw %}
-docker --log-driver=syslog --log-opt tag="{{.ImageName}}/{{.Name}}/{{.ID}}"
-{% endraw %}
-```
-
-### LXC built-in exec driver

-
-**Removed In Release: [v1.10.0](https://github.com/docker/docker/releases/tag/v1.10.0)**
-
-The built-in LXC execution driver, the lxc-conf flag, and API fields have been removed.
-
-### Old Command Line Options
-**Deprecated In Release: [v1.8.0](https://github.com/docker/docker/releases/tag/v1.8.0)**
-
-**Removed In Release: [v1.10.0](https://github.com/docker/docker/releases/tag/v1.10.0)**
-
-The flags `-d` and `--daemon` are deprecated in favor of the `daemon` subcommand:
-
-    docker daemon -H ...
-
-The following single-dash (`-opt`) variant of certain command line options
-are deprecated and replaced with double-dash options (`--opt`):
-
-    docker attach -nostdin

-
-**Removed In Release: [v1.13.0](https://github.com/docker/docker/releases/tag/v1.13.0)**
-
-The flag `--run` of the docker commit (and its short version `-run`) were deprecated in favor

-### Interacting with V1 registries
-
-**Disabled By Default In Release: v17.06**
-
-**Target For Removal In Release: v17.12**
-
-Version 1.8.3 added a flag (`--disable-legacy-registry=false`) which prevents the
-docker daemon from `pull`, `push`, and `login` operations against v1
-registries.  Though enabled by default, this signals the intent to deprecate
-the v1 protocol.
-

-
-Since 1.9, Docker Content Trust Offline key has been renamed to Root key and the Tagging key has been renamed to Repository key. Due to this renaming, we're also changing the corresponding environment variables
-
-- DOCKER_CONTENT_TRUST_OFFLINE_PASSPHRASE is now named DOCKER_CONTENT_TRUST_ROOT_PASSPHRASE
-- DOCKER_CONTENT_TRUST_TAGGING_PASSPHRASE is now named DOCKER_CONTENT_TRUST_REPOSITORY_PASSPHRASE

-# A proof-of-concept Rexray plugin
-
-In this example, a simple Rexray plugin will be created for the purposes of using
-it on an Amazon EC2 instance with EBS. It is not meant to be a complete Rexray plugin.
-
-The example source is available at [https://github.com/tiborvass/rexray-plugin](https://github.com/tiborvass/rexray-plugin).
-
-To learn more about Rexray: [https://github.com/codedellemc/rexray](https://github.com/codedellemc/rexray)
-
-## 1. Make a Docker image
-
-The following is the Dockerfile used to containerize rexray.
-
-```Dockerfile
-FROM debian:jessie
-RUN apt-get update && apt-get install -y --no-install-recommends wget ca-certificates
-RUN wget https://dl.bintray.com/emccode/rexray/stable/0.6.4/rexray-Linux-x86_64-0.6.4.tar.gz -O rexray.tar.gz && tar -xvzf rexray.tar.gz -C /usr/bin && rm rexray.tar.gz
-RUN mkdir -p /run/docker/plugins /var/lib/libstorage/volumes
-ENTRYPOINT ["rexray"]
-CMD ["--help"]
-```
-
-To build it you can run `image=$(cat Dockerfile | docker build -q -)` and `$image`
-will reference the containerized rexray image.
-
-## 2. Extract rootfs
-
-```sh
-$ TMPDIR=/tmp/rexray  # for the purpose of this example
-$  # create container without running it, to extract the rootfs from image
-$ docker create --name rexray "$image"
-$  # save the rootfs to a tar archive
-$ docker export -o $TMPDIR/rexray.tar rexray
-$  # extract rootfs from tar archive to a rootfs folder
-$ ( mkdir -p $TMPDIR/rootfs; cd $TMPDIR/rootfs; tar xf ../rexray.tar )
-```
-
-## 3. Add plugin configuration
-
-We have to put the following JSON to `$TMPDIR/config.json`:
-
-```json
-{
-      "Args": {
-        "Description": "",
-        "Name": "",
-        "Settable": null,
-        "Value": null
-      },
-      "Description": "A proof-of-concept EBS plugin (using rexray) for Docker",
-      "Documentation": "https://github.com/tiborvass/rexray-plugin",
-      "Entrypoint": [
-        "/usr/bin/rexray", "service", "start", "-f"
-      ],
-      "Env": [
-        {
-          "Description": "",
-          "Name": "REXRAY_SERVICE",
-          "Settable": [
-            "value"
-          ],
-          "Value": "ebs"
-        },
-        {
-          "Description": "",
-          "Name": "EBS_ACCESSKEY",
-          "Settable": [
-            "value"
-          ],
-          "Value": ""
-        },
-        {
-          "Description": "",
-          "Name": "EBS_SECRETKEY",
-          "Settable": [
-            "value"
-          ],
-          "Value": ""
-        }
-      ],
-      "Interface": {
-        "Socket": "rexray.sock",
-        "Types": [
-          "docker.volumedriver/1.0"
-        ]
-      },
-      "Linux": {
-        "AllowAllDevices": true,
-        "Capabilities": ["CAP_SYS_ADMIN"],
-        "Devices": null
-      },
-      "Mounts": [
-        {
-          "Source": "/dev",
-          "Destination": "/dev",
-          "Type": "bind",
-          "Options": ["rbind"]
-        }
-      ],
-      "Network": {
-        "Type": "host"
-      },
-      "PropagatedMount": "/var/lib/libstorage/volumes",
-      "User": {},
-      "WorkDir": ""
-}
-```
-
-Please note a couple of points:
-- `PropagatedMount` is needed so that the docker daemon can see mounts done by the
-rexray plugin from within the container, otherwise the docker daemon is not able
-to mount a docker volume.
-- The rexray plugin needs dynamic access to host devices. For that reason, we
-have to give it access to all devices under `/dev` and set `AllowAllDevices` to
-true for proper access.
-- The user of this simple plugin can change only 3 settings: `REXRAY_SERVICE`,
-`EBS_ACCESSKEY` and `EBS_SECRETKEY`. This is because of the reduced scope of this
-plugin. Ideally other rexray parameters could also be set.
-
-## 4. Create plugin
-
-`docker plugin create tiborvass/rexray-plugin "$TMPDIR"` will create the plugin.
-
-```sh
-$ docker plugin ls
-ID                  NAME                             DESCRIPTION                         ENABLED
-2475a4bd0ca5        tiborvass/rexray-plugin:latest   A rexray volume plugin for Docker   false
-```
-
-## 5. Test plugin
-
-```sh
-$ docker plugin set tiborvass/rexray-plugin EBS_ACCESSKEY=$AWS_ACCESSKEY EBS_SECRETKEY=$AWS_SECRETKEY`
-$ docker plugin enable tiborvass/rexray-plugin
-$ docker volume create -d tiborvass/rexray-plugin my-ebs-volume
-$ docker volume ls
-DRIVER                              VOLUME NAME
-tiborvass/rexray-plugin:latest      my-ebs-volume
-$ docker run --rm -v my-ebs-volume:/volume busybox sh -c 'echo bye > /volume/hi'
-$ docker run --rm -v my-ebs-volume:/volume busybox cat /volume/hi
-bye
-```
-
-## 6. Push plugin
-
-First, ensure you are logged in with `docker login`. Then you can run:
-`docker plugin push tiborvass/rexray-plugin` to push it like a regular docker
-image to a registry, to make it available for others to install via
-`docker plugin install tiborvass/rexray-plugin EBS_ACCESSKEY=$AWS_ACCESSKEY EBS_SECRETKEY=$AWS_SECRETKEY`.

-
-* [Installing and using a plugin](index.md#installing-and-using-a-plugin)
-* [Developing a plugin](index.md#developing-a-plugin)
-* [Debugging plugins](index.md#debugging-plugins)
-
-Docker Engine's plugin system allows you to install, start, stop, and remove
-plugins using Docker Engine.
-
-For information about the legacy plugin system available in Docker Engine 1.12
-and earlier, see [Understand legacy Docker Engine plugins](legacy_plugins.md).
-
-> **Note**: Docker Engine managed plugins are currently not supported
-on Windows daemons.
-
-## Installing and using a plugin
-
-Plugins are distributed as Docker images and can be hosted on Docker Hub or on
-a private registry.
-
-To install a plugin, use the `docker plugin install` command, which pulls the
-plugin from Docker Hub or your private registry, prompts you to grant
-permissions or capabilities if necessary, and enables the plugin.
-
-To check the status of installed plugins, use the `docker plugin ls` command.
-Plugins that start successfully are listed as enabled in the output.
-
-After a plugin is installed, you can use it as an option for another Docker
-operation, such as creating a volume.
-
-In the following example, you install the `sshfs` plugin, verify that it is
-enabled, and use it to create a volume.
-
-> **Note**: This example is intended for instructional purposes only. Once the volume is created, your SSH password to the remote host will be exposed as plaintext when inspecting the volume. You should delete the volume as soon as you are done with the example.
-
-1.  Install the `sshfs` plugin.
-
-    ```bash
-    $ docker plugin install vieux/sshfs
-
-    Plugin "vieux/sshfs" is requesting the following privileges:
-    - network: [host]
-    - capabilities: [CAP_SYS_ADMIN]
-    Do you grant the above permissions? [y/N] y
-
-    vieux/sshfs
-    ```
-
-    The plugin requests 2 privileges:
-    
-    - It needs access to the `host` network.
-    - It needs the `CAP_SYS_ADMIN` capability, which allows the plugin to run
-    the `mount` command.
-
-2.  Check that the plugin is enabled in the output of `docker plugin ls`.
-
-    ```bash
-    $ docker plugin ls
-
-    ID                    NAME                  TAG                 DESCRIPTION                   ENABLED
-    69553ca1d789          vieux/sshfs           latest              the `sshfs` plugin            true
-    ```
-
-3.  Create a volume using the plugin.
-    This example mounts the `/remote` directory on host `1.2.3.4` into a
-    volume named `sshvolume`.   
-
-    This volume can now be mounted into containers.
-
-    ```bash
-    $ docker volume create \
-      -d vieux/sshfs \
-      --name sshvolume \
-      -o sshcmd=user@1.2.3.4:/remote \
-      -o password=$(cat file_containing_password_for_remote_host)
-
-    sshvolume
-    ```
-4.  Verify that the volume was created successfully.
-
-    ```bash
-    $ docker volume ls
-
-    DRIVER              NAME
-    vieux/sshfs         sshvolume
-    ```
-
-5.  Start a container that uses the volume `sshvolume`.
-
-    ```bash
-    $ docker run --rm -v sshvolume:/data busybox ls /data
-
-    <content of /remote on machine 1.2.3.4>
-    ```
-
-6.  Remove the volume `sshvolume`
-    ```bash
-    docker volume rm sshvolume
-
-    sshvolume
-    ```
-To disable a plugin, use the `docker plugin disable` command. To completely
-remove it, use the `docker plugin remove` command. For other available
-commands and options, see the
-[command line reference](../reference/commandline/index.md).
-
-
-## Developing a plugin
-
-#### The rootfs directory
-The `rootfs` directory represents the root filesystem of the plugin. In this
-example, it was created from a Dockerfile:
-
->**Note:** The `/run/docker/plugins` directory is mandatory inside of the
-plugin's filesystem for docker to communicate with the plugin.
-
-```bash
-$ git clone https://github.com/vieux/docker-volume-sshfs
-$ cd docker-volume-sshfs
-$ docker build -t rootfsimage .
-$ id=$(docker create rootfsimage true) # id was cd851ce43a403 when the image was created
-$ sudo mkdir -p myplugin/rootfs
-$ sudo docker export "$id" | sudo tar -x -C myplugin/rootfs
-$ docker rm -vf "$id"
-$ docker rmi rootfsimage
-```
-
-#### The config.json file
-
-The `config.json` file describes the plugin. See the [plugins config reference](config.md).
-
-Consider the following `config.json` file.
-
-```json
-{
-	"description": "sshFS plugin for Docker",
-	"documentation": "https://docs.docker.com/engine/extend/plugins/",
-	"entrypoint": ["/docker-volume-sshfs"],
-	"network": {
-		   "type": "host"
-		   },
-	"interface" : {
-		   "types": ["docker.volumedriver/1.0"],
-		   "socket": "sshfs.sock"
-	},
-	"linux": {
-		"capabilities": ["CAP_SYS_ADMIN"]
-	}
-}
-```
-
-This plugin is a volume driver. It requires a `host` network and the
-`CAP_SYS_ADMIN` capability. It depends upon the `/docker-volume-sshfs`
-entrypoint and uses the `/run/docker/plugins/sshfs.sock` socket to communicate
-with Docker Engine. This plugin has no runtime parameters.
-
-#### Creating the plugin
-
-A new plugin can be created by running
-`docker plugin create <plugin-name> ./path/to/plugin/data` where the plugin
-data contains a plugin configuration file `config.json` and a root filesystem
-in subdirectory `rootfs`.
-
-After that the plugin `<plugin-name>` will show up in `docker plugin ls`.
-Plugins can be pushed to remote registries with
-`docker plugin push <plugin-name>`.
-
-
-## Debugging plugins
-
-Stdout of a plugin is redirected to dockerd logs. Such entries have a
-`plugin=<ID>` suffix. Here are a few examples of commands for pluginID
-`f52a3df433b9aceee436eaada0752f5797aab1de47e5485f1690a073b860ff62` and their
-corresponding log entries in the docker daemon logs.
-
-```bash
-$ docker plugin install tiborvass/sample-volume-plugins
-
-INFO[0036] Starting...       Found 0 volumes on startup  plugin=f52a3df433b9aceee436eaada0752f5797aab1de47e5485f1690a073b860ff62
-```
-
-```bash
-$ docker volume create -d tiborvass/sample-volume-plugins samplevol
-
-INFO[0193] Create Called...  Ensuring directory /data/samplevol exists on host...  plugin=f52a3df433b9aceee436eaada0752f5797aab1de47e5485f1690a073b860ff62

-```
-
-```bash
-$ docker run -v samplevol:/tmp busybox sh
-
-INFO[0421] Get Called...     Found samplevol                plugin=f52a3df433b9aceee436eaada0752f5797aab1de47e5485f1690a073b860ff62

-```
-
-#### Using docker-runc to obtain logfiles and shell into the plugin.
-
-`docker-runc`, the default docker container runtime can be used for debugging
-plugins. This is specifically useful to collect plugin logs if they are
-redirected to a file.
-
-```bash
-$ docker-runc list
-ID                                                                 PID         STATUS      BUNDLE                                                                                       CREATED
-f52a3df433b9aceee436eaada0752f5797aab1de47e5485f1690a073b860ff62   2679        running     /run/docker/libcontainerd/f52a3df433b9aceee436eaada0752f5797aab1de47e5485f1690a073b860ff62	2017-02-06T21:53:03.031537592Z
-r
-```
-
-```bash
-$ docker-runc exec f52a3df433b9aceee436eaada0752f5797aab1de47e5485f1690a073b860ff62 cat /var/log/plugin.log
-```
-
-If the plugin has a built-in shell, then exec into the plugin can be done as
-follows:
-```bash
-$ docker-runc exec -t f52a3df433b9aceee436eaada0752f5797aab1de47e5485f1690a073b860ff62 sh
-```
-
-#### Using curl to debug plugin socket issues.
-
-To verify if the plugin API socket that the docker daemon communicates with
-is responsive, use curl. In this example, we will make API calls from the
-docker host to volume and network plugins using curl 7.47.0 to ensure that
-the plugin is listening on the said socket. For a well functioning plugin,
-these basic requests should work. Note that plugin sockets are available on the host under `/var/run/docker/plugins/<pluginID>`
-
-
-```bash
-curl -H "Content-Type: application/json" -XPOST -d '{}' --unix-socket /var/run/docker/plugins/e8a37ba56fc879c991f7d7921901723c64df6b42b87e6a0b055771ecf8477a6d/plugin.sock http:/VolumeDriver.List
-
-{"Mountpoint":"","Err":"","Volumes":[{"Name":"myvol1","Mountpoint":"/data/myvol1"},{"Name":"myvol2","Mountpoint":"/data/myvol2"}],"Volume":null}
-```
-
-```bash
-curl -H "Content-Type: application/json" -XPOST -d '{}' --unix-socket /var/run/docker/plugins/45e00a7ce6185d6e365904c8bcf62eb724b1fe307e0d4e7ecc9f6c1eb7bcdb70/plugin.sock http:/NetworkDriver.GetCapabilities
-
-{"Scope":"local"}
-```
-When using curl 7.5 and above, the URL should be of the form
-`http://hostname/APICall`, where `hostname` is the valid hostname where the
-plugin is installed and `APICall` is the call to the plugin API.
-
-For example, `http://localhost/VolumeDriver.List`

-This document describes the Docker Engine plugins generally available in Docker
-Engine. To view information on plugins managed by Docker,
-refer to [Docker Engine plugin system](index.md).
-
-You can extend the capabilities of the Docker Engine by loading third-party
-plugins. This page explains the types of plugins and provides links to several
-volume and network plugins for Docker.
-
-## Types of plugins
-
-Plugins extend Docker's functionality. They come in specific types.  For
-example, a [volume plugin](plugins_volume.md) might enable Docker
-volumes to persist across multiple Docker hosts and a
-[network plugin](plugins_network.md) might provide network plumbing.
-
-Currently Docker supports authorization, volume and network driver plugins. In the future it
-will support additional plugin types.
-
-## Installing a plugin
-
-Follow the instructions in the plugin's documentation.
-
-## Finding a plugin

-# Docker Plugin API
-
-Docker plugins are out-of-process extensions which add capabilities to the
-Docker Engine.
-
-This document describes the Docker Engine plugin API. To view information on
-plugins managed by Docker Engine, refer to [Docker Engine plugin system](index.md).
-
-This page is intended for people who want to develop their own Docker plugin.
-If you just want to learn about or use Docker plugins, look
-[here](legacy_plugins.md).
-
-## What plugins are
-
-A plugin is a process running on the same or a different host as the docker daemon,
-which registers itself by placing a file on the same docker host in one of the plugin
-directories described in [Plugin discovery](#plugin-discovery).
-
-Plugins have human-readable names, which are short, lowercase strings. For
-example, `flocker` or `weave`.
-
-Plugins can run inside or outside containers. Currently running them outside
-containers is recommended.
-
-## Plugin discovery
-
-Docker discovers plugins by looking for them in the plugin directory whenever a
-user or container tries to use one by name.
-
-There are three types of files which can be put in the plugin directory.
-
-* `.sock` files are UNIX domain sockets.
-* `.spec` files are text files containing a URL, such as `unix:///other.sock` or `tcp://localhost:8080`.
-* `.json` files are text files containing a full json specification for the plugin.
-
-Plugins with UNIX domain socket files must run on the same docker host, whereas
-plugins with spec or json files can run on a different host if a remote URL is specified.
-
-UNIX domain socket files must be located under `/run/docker/plugins`, whereas
-spec files can be located either under `/etc/docker/plugins` or `/usr/lib/docker/plugins`.
-
-The name of the file (excluding the extension) determines the plugin name.
-
-For example, the `flocker` plugin might create a UNIX socket at
-`/run/docker/plugins/flocker.sock`.
-
-You can define each plugin into a separated subdirectory if you want to isolate definitions from each other.
-For example, you can create the `flocker` socket under `/run/docker/plugins/flocker/flocker.sock` and only
-mount `/run/docker/plugins/flocker` inside the `flocker` container.
-
-Docker always searches for unix sockets in `/run/docker/plugins` first. It checks for spec or json files under
-`/etc/docker/plugins` and `/usr/lib/docker/plugins` if the socket doesn't exist. The directory scan stops as
-soon as it finds the first plugin definition with the given name.
-
-### JSON specification
-
-This is the JSON format for a plugin:
-
-```json
-{
-  "Name": "plugin-example",
-  "Addr": "https://example.com/docker/plugin",
-  "TLSConfig": {
-    "InsecureSkipVerify": false,
-    "CAFile": "/usr/shared/docker/certs/example-ca.pem",
-    "CertFile": "/usr/shared/docker/certs/example-cert.pem",
-    "KeyFile": "/usr/shared/docker/certs/example-key.pem"
-  }
-}
-```
-
-The `TLSConfig` field is optional and TLS will only be verified if this configuration is present.
-
-## Plugin lifecycle
-
-Plugins should be started before Docker, and stopped after Docker.  For
-example, when packaging a plugin for a platform which supports `systemd`, you
-might use [`systemd` dependencies](
-http://www.freedesktop.org/software/systemd/man/systemd.unit.html#Before=) to
-manage startup and shutdown order.
-
-When upgrading a plugin, you should first stop the Docker daemon, upgrade the
-plugin, then start Docker again.
-
-## Plugin activation
-
-When a plugin is first referred to -- either by a user referring to it by name
-(e.g.  `docker run --volume-driver=foo`) or a container already configured to
-use a plugin being started -- Docker looks for the named plugin in the plugin
-directory and activates it with a handshake. See Handshake API below.
-
-Plugins are *not* activated automatically at Docker daemon startup. Rather,
-they are activated only lazily, or on-demand, when they are needed.
-
-## Systemd socket activation
-
-Plugins may also be socket activated by `systemd`. The official [Plugins helpers](https://github.com/docker/go-plugins-helpers)
-natively supports socket activation. In order for a plugin to be socket activated it needs
-a `service` file and a `socket` file.
-
-The `service` file (for example `/lib/systemd/system/your-plugin.service`):
-
-```
-[Unit]
-Description=Your plugin
-Before=docker.service
-After=network.target your-plugin.socket
-Requires=your-plugin.socket docker.service
-
-[Service]
-ExecStart=/usr/lib/docker/your-plugin
-
-[Install]
-WantedBy=multi-user.target
-```
-The `socket` file (for example `/lib/systemd/system/your-plugin.socket`):
-
-```
-[Unit]
-Description=Your plugin
-
-[Socket]
-ListenStream=/run/docker/plugins/your-plugin.sock
-
-[Install]
-WantedBy=sockets.target
-```
-
-This will allow plugins to be actually started when the Docker daemon connects to
-the sockets they're listening on (for instance the first time the daemon uses them
-or if one of the plugin goes down accidentally).
-
-## API design
-
-The Plugin API is RPC-style JSON over HTTP, much like webhooks.
-
-Requests flow *from* the Docker daemon *to* the plugin.  So the plugin needs to
-implement an HTTP server and bind this to the UNIX socket mentioned in the
-"plugin discovery" section.
-
-All requests are HTTP `POST` requests.
-
-The API is versioned via an Accept header, which currently is always set to
-`application/vnd.docker.plugins.v1+json`.
-
-## Handshake API
-
-Plugins are activated via the following "handshake" API call.
-
-### /Plugin.Activate
-
-**Request:** empty body
-
-**Response:**
-```
-{
-    "Implements": ["VolumeDriver"]
-}
-```
-
-Responds with a list of Docker subsystems which this plugin implements.
-After activation, the plugin will then be sent events from this subsystem.
-
-Possible values are:
-
-* [`authz`](plugins_authorization.md)
-* [`NetworkDriver`](plugins_network.md)
-* [`VolumeDriver`](plugins_volume.md)
-
-
-## Plugin retries
-
-Attempts to call a method on a plugin are retried with an exponential backoff
-for up to 30 seconds. This may help when packaging plugins as containers, since
-it gives plugin containers a chance to start up before failing any user
-containers which depend on them.
-
-## Plugins helpers
-
-To ease plugins development, we're providing an `sdk` for each kind of plugins
-currently supported by Docker at [docker/go-plugins-helpers](https://github.com/docker/go-plugins-helpers).

-# Create an authorization plugin
-
-This document describes the Docker Engine plugins generally available in Docker
-Engine. To view information on plugins managed by Docker Engine,
-refer to [Docker Engine plugin system](index.md).
-
-Docker's out-of-the-box authorization model is all or nothing. Any user with
-permission to access the Docker daemon can run any Docker client command. The
-same is true for callers using Docker's Engine API to contact the daemon. If you
-require greater access control, you can create authorization plugins and add
-them to your Docker daemon configuration. Using an authorization plugin, a
-Docker administrator can configure granular access policies for managing access
-to Docker daemon.
-
-Anyone with the appropriate skills can develop an authorization plugin. These
-skills, at their most basic, are knowledge of Docker, understanding of REST, and
-sound programming knowledge. This document describes the architecture, state,
-and methods information available to an authorization plugin developer.
-
-## Basic principles
-
-Docker's [plugin infrastructure](plugin_api.md) enables
-extending Docker by loading, removing and communicating with
-third-party components using a generic API. The access authorization subsystem
-was built using this mechanism.
-
-Using this subsystem, you don't need to rebuild the Docker daemon to add an
-authorization plugin.  You can add a plugin to an installed Docker daemon. You do
-need to restart the Docker daemon to add a new plugin.
-
-An authorization plugin approves or denies requests to the Docker daemon based
-on both the current authentication context and the command context. The
-authentication context contains all user details and the authentication method.
-The command context contains all the relevant request data.
-
-Authorization plugins must follow the rules described in [Docker Plugin API](plugin_api.md).
-Each plugin must reside within directories described under the
-[Plugin discovery](plugin_api.md#plugin-discovery) section.
-
-**Note**: the abbreviations `AuthZ` and `AuthN` mean authorization and authentication
-respectively.
-
-## Default user authorization mechanism
-
-If TLS is enabled in the [Docker daemon](https://docs.docker.com/engine/security/https/), the default user authorization flow extracts the user details from the certificate subject name.
-That is, the `User` field is set to the client certificate subject common name, and the `AuthenticationMethod` field is set to `TLS`.
-
-## Basic architecture
-
-You are responsible for registering your plugin as part of the Docker daemon
-startup. You can install multiple plugins and chain them together. This chain
-can be ordered. Each request to the daemon passes in order through the chain.
-Only when all the plugins grant access to the resource, is the access granted.
-
-When an HTTP request is made to the Docker daemon through the CLI or via the
-Engine API, the authentication subsystem passes the request to the installed
-authentication plugin(s). The request contains the user (caller) and command
-context. The plugin is responsible for deciding whether to allow or deny the
-request.
-
-The sequence diagrams below depict an allow and deny authorization flow:
-
-![Authorization Allow flow](images/authz_allow.png)
-
-![Authorization Deny flow](images/authz_deny.png)
-
-Each request sent to the plugin includes the authenticated user, the HTTP
-headers, and the request/response body. Only the user name and the
-authentication method used are passed to the plugin. Most importantly, no user
-credentials or tokens are passed. Finally, not all request/response bodies
-are sent to the authorization plugin. Only those request/response bodies where
-the `Content-Type` is either `text/*` or `application/json` are sent.
-
-For commands that can potentially hijack the HTTP connection (`HTTP
-Upgrade`), such as `exec`, the authorization plugin is only called for the
-initial HTTP requests. Once the plugin approves the command, authorization is
-not applied to the rest of the flow. Specifically, the streaming data is not
-passed to the authorization plugins. For commands that return chunked HTTP
-response, such as `logs` and `events`, only the HTTP request is sent to the
-authorization plugins.
-
-During request/response processing, some authorization flows might
-need to do additional queries to the Docker daemon. To complete such flows,
-plugins can call the daemon API similar to a regular user. To enable these
-additional queries, the plugin must provide the means for an administrator to
-configure proper authentication and security policies.
-
-## Docker client flows
-
-To enable and configure the authorization plugin, the plugin developer must
-support the Docker client interactions detailed in this section.
-
-### Setting up Docker daemon
-
-Enable the authorization plugin with a dedicated command line flag in the
-`--authorization-plugin=PLUGIN_ID` format. The flag supplies a `PLUGIN_ID`
-value. This value can be the plugin’s socket or a path to a specification file.
-Authorization plugins can be loaded without restarting the daemon. Refer
-to the [`dockerd` documentation](../reference/commandline/dockerd.md#configuration-reloading) for more information.
-
-```bash
-$ dockerd --authorization-plugin=plugin1 --authorization-plugin=plugin2,...
-```
-
-Docker's authorization subsystem supports multiple `--authorization-plugin` parameters.
-
-### Calling authorized command (allow)
-
-```bash
-$ docker pull centos
-...
-f1b10cd84249: Pull complete
-...
-```
-
-### Calling unauthorized command (deny)
-
-```bash
-$ docker pull centos
-...
-docker: Error response from daemon: authorization denied by plugin PLUGIN_NAME: volumes are not allowed.
-```
-
-### Error from plugins
-
-```bash
-$ docker pull centos
-...
-docker: Error response from daemon: plugin PLUGIN_NAME failed with error: AuthZPlugin.AuthZReq: Cannot connect to the Docker daemon. Is the docker daemon running on this host?.
-```
-
-## API schema and implementation
-
-In addition to Docker's standard plugin registration method, each plugin
-should implement the following two methods:
-
-* `/AuthZPlugin.AuthZReq` This authorize request method is called before the Docker daemon processes the client request.
-
-* `/AuthZPlugin.AuthZRes` This authorize response method is called before the response is returned from Docker daemon to the client.
-
-#### /AuthZPlugin.AuthZReq
-
-**Request**:
-
-```json
-{
-    "User":              "The user identification",
-    "UserAuthNMethod":   "The authentication method used",
-    "RequestMethod":     "The HTTP method",
-    "RequestURI":        "The HTTP request URI",
-    "RequestBody":       "Byte array containing the raw HTTP request body",
-    "RequestHeader":     "Byte array containing the raw HTTP request header as a map[string][]string "
-}
-```
-
-**Response**:
-
-```json
-{
-    "Allow": "Determined whether the user is allowed or not",
-    "Msg":   "The authorization message",
-    "Err":   "The error message if things go wrong"
-}
-```
-#### /AuthZPlugin.AuthZRes
-
-**Request**:
-
-```json
-{
-    "User":              "The user identification",
-    "UserAuthNMethod":   "The authentication method used",
-    "RequestMethod":     "The HTTP method",
-    "RequestURI":        "The HTTP request URI",
-    "RequestBody":       "Byte array containing the raw HTTP request body",
-    "RequestHeader":     "Byte array containing the raw HTTP request header as a map[string][]string",
-    "ResponseBody":      "Byte array containing the raw HTTP response body",
-    "ResponseHeader":    "Byte array containing the raw HTTP response header as a map[string][]string",
-    "ResponseStatusCode":"Response status code"
-}
-```
-
-**Response**:
-
-```json
-{
-   "Allow":              "Determined whether the user is allowed or not",

-   "Err":                "The error message if things go wrong"
-}
-```
-
-### Request authorization

-# Docker graph driver plugins
-
-Docker graph driver plugins enable admins to use an external/out-of-process
-graph driver for use with Docker engine. This is an alternative to using the
-built-in storage drivers, such as aufs/overlay/devicemapper/btrfs.
-
-You need to install and enable the plugin and then restart the Docker daemon
-before using the plugin. See the following example for the correct ordering
-of steps.
-
-```
-$ docker plugin install cpuguy83/docker-overlay2-graphdriver-plugin # this command also enables the driver
-<output suppressed>
-$ pkill dockerd
-$ dockerd --experimental -s cpuguy83/docker-overlay2-graphdriver-plugin
-```
-
-# Write a graph driver plugin
-
-See the [plugin documentation](https://docs.docker.com/engine/extend/) for detailed information
-on the underlying plugin protocol.

-If a plugin registers itself as a `GraphDriver` when activated, then it is
-expected to provide the rootfs for containers as well as image layer storage.
-
-### /GraphDriver.Init
-
-**Request**:
-```json
-{
-  "Home": "/graph/home/path",
-  "Opts": [],
-  "UIDMaps": [],
-  "GIDMaps": []
-}
-```
-
-Initialize the graph driver plugin with a home directory and array of options.
-These are passed through from the user, but the plugin is not required to parse
-or honor them.
-
-The request also includes a list of UID and GID mappings, structed as follows:
-```json
-{
-  "ContainerID": 0,
-  "HostID": 0,
-  "Size": 0
-}
-```
-
-**Response**:
-```json
-{
-  "Err": ""
-}
-```
-
-Respond with a non-empty string error if an error occurred.
-
-
-### /GraphDriver.Capabilities
-
-**Request**:
-```json
-{}
-```
-
-Get behavioral characteristics of the graph driver. If a plugin does not handle
-this request, the engine will use default values for all capabilities.
-
-**Response**:
-```json
-{
-  "ReproducesExactDiffs": false,
-}
-```
-
-Respond with values of capabilities:
-
-* **ReproducesExactDiffs** Defaults to false. Flags that this driver is capable
-of reproducing exactly equivalent diffs for read-only filesystem layers.

-# Logging driver plugins
-
-This document describes logging driver plugins for Docker.
-
-Logging drivers enables users to forward container logs to another service for
-processing. Docker includes several logging drivers as built-ins, however can
-never hope to support all use-cases with built-in drivers. Plugins allow Docker
-to support a wide range of logging services without requiring to embed client
-libraries for these services in the main Docker codebase. See the
-[plugin documentation](legacy_plugins.md) for more information.
-
-## Create a logging plugin
-
-The main interface for logging plugins uses the same JSON+HTTP RPC protocol used
-by other plugin types. See the
-[example](https://github.com/cpuguy83/docker-log-driver-test) plugin for a
-reference implementation of a logging plugin. The example wraps the built-in
-`jsonfilelog` log driver.
-
-## LogDriver protocol
-
-Logging plugins must register as a `LogDriver` during plugin activation. Once
-activated users can specify the plugin as a log driver.
-
-There are two HTTP endpoints that logging plugins must implement:
-
-### `/LogDriver.StartLogging`
-
-Signals to the plugin that a container is starting that the plugin should start
-receiving logs for.
-
-Logs will be streamed over the defined file in the request. On Linux this file
-is a FIFO. Logging plugins are not currently supported on Windows.
-
-**Request**:
-```json
-{
-		"File": "/path/to/file/stream",
-		"Info": {
-			"ContainerID": "123456"
-		}
-}
-```
-
-`File` is the path to the log stream that needs to be consumed. Each call to
-`StartLogging` should provide a different file path, even if it's a container
-that the plugin has already received logs for prior. The file is created by
-docker with a randomly generated name.
-
-`Info` is details about the container that's being logged. This is fairly
-free-form, but is defined by the following struct definition:
-
-```go
-type Info struct {
-	Config              map[string]string
-	ContainerID         string
-	ContainerName       string
-	ContainerEntrypoint string
-	ContainerArgs       []string
-	ContainerImageID    string
-	ContainerImageName  string
-	ContainerCreated    time.Time
-	ContainerEnv        []string
-	ContainerLabels     map[string]string
-	LogPath             string
-	DaemonName          string
-}
-```
-
-
-`ContainerID` will always be supplied with this struct, but other fields may be
-empty or missing.
-
-**Response**
-```json
-{
-	"Err": ""
-}
-```
-
-If an error occurred during this request, add an error message to the `Err` field
-in the response. If no error then you can either send an empty response (`{}`)
-or an empty value for the `Err` field.
-
-The driver should at this point be consuming log messages from the passed in file.
-If messages are unconsumed, it may cause the container to block while trying to
-write to its stdio streams.
-
-Log stream messages are encoded as protocol buffers. The protobuf definitions are
-in the
-[docker repository](https://github.com/docker/docker/blob/master/api/types/plugins/logdriver/entry.proto).
-
-Since protocol buffers are not self-delimited you must decode them from the stream
-using the following stream format:
-
-```
-[size][message]
-```
-
-Where `size` is a 4-byte big endian binary encoded uint32. `size` in this case
-defines the size of the next message. `message` is the actual log entry.
-
-A reference golang implementation of a stream encoder/decoder can be found
-[here](https://github.com/docker/docker/blob/master/api/types/plugins/logdriver/io.go)
-
-### `/LogDriver.StopLogging`
-
-Signals to the plugin to stop collecting logs from the defined file.
-Once a response is received, the file will be removed by Docker. You must make
-sure to collect all logs on the stream before responding to this request or risk
-losing log data.
-
-Requests on this endpoint does not mean that the container has been removed
-only that it has stopped.
-
-**Request**:
-```json
-{
-		"File": "/path/to/file/stream"
-}
-```
-
-**Response**:
-```json
-{
-	"Err": ""
-}
-```
-
-If an error occurred during this request, add an error message to the `Err` field
-in the response. If no error then you can either send an empty response (`{}`)
-or an empty value for the `Err` field.
-
-## Optional endpoints
-
-Logging plugins can implement two extra logging endpoints:
-
-### `/LogDriver.Capabilities`
-
-Defines the capabilities of the log driver. You must implement this endpoint for
-Docker to be able to take advantage of any of the defined capabilities.
-
-**Request**:
-```json
-{}
-```
-
-**Response**:
-```json
-{
-	"ReadLogs": true
-}
-```
-
-Supported capabilities:
-
-- `ReadLogs` - this tells Docker that the plugin is capable of reading back logs
-to clients. Plugins that report that they support `ReadLogs` must implement the
-`/LogDriver.ReadLogs` endpoint
-
-### `/LogDriver.ReadLogs`
-
-Reads back logs to the client. This is used when `docker logs <container>` is
-called.
-
-In order for Docker to use this endpoint, the plugin must specify as much when
-`/LogDriver.Capabilities` is called.
-
-
-**Request**:
-```json
-{
-	"ReadConfig": {},
-	"Info": {
-		"ContainerID": "123456"
-	}
-}
-```
-
-`ReadConfig` is the list of options for reading, it is defined with the following
-golang struct:
-
-```go
-type ReadConfig struct {
-	Since  time.Time
-	Tail   int
-	Follow bool
-}
-```
-
-- `Since` defines the oldest log that should be sent.
-- `Tail` defines the number of lines to read (e.g. like the command `tail -n 10`)
-- `Follow` signals that the client wants to stay attached to receive new log messages
-as they come in once the existing logs have been read.
-
-`Info` is the same type defined in `/LogDriver.StartLogging`. It should be used
-to determine what set of logs to read.
-
-**Response**:
-```
-{{ log stream }}
-```
-
-The response should be the encoded log message using the same format as the
-messages that the plugin consumed from Docker.

-# Metrics Collector Plugins
-
-Docker exposes internal metrics based on the prometheus format. Metrics plugins
-enable accessing these metrics in a consistent way by providing a Unix
-socket at a predefined path where the plugin can scrape the metrics.
-
-> **Note**: that while the plugin interface for metrics is non-experimental, the naming
-of the metrics and metric labels is still considered experimental and may change
-in a future version.
-
-## Creating a metrics plugin
-
-You must currently set `PropagatedMount` in the plugin `config.json` to
-`/run/docker`. This allows the plugin to receive updated mounts
-(the bind-mounted socket) from Docker after the plugin is already configured.
-
-## MetricsCollector protocol
-
-Metrics plugins must register as implementing the`MetricsCollector` interface
-in `config.json`.
-
-On Unix platforms, the socket is located at `/run/docker/metrics.sock` in the
-plugin's rootfs.
-
-`MetricsCollector` must implement two endpoints:
-
-### `MetricsCollector.StartMetrics`
-
-Signals to the plugin that the metrics socket is now available for scraping
-
-**Request**
-```json
-{}
-```
-
-The request has no playload.
-
-**Response**
-```json
-{
-	"Err": ""
-}
-```
-
-If an error occurred during this request, add an error message to the `Err` field
-in the response. If no error then you can either send an empty response (`{}`)
-or an empty value for the `Err` field. Errors will only be logged.
-
-### `MetricsCollector.StopMetrics`
-
-Signals to the plugin that the metrics socket is no longer available.
-This may happen when the daemon is shutting down.
-
-**Request**
-```json
-{}
-```
-
-The request has no playload.
-
-**Response**
-```json
-{
-	"Err": ""
-}
-```
-
-If an error occurred during this request, add an error message to the `Err` field
-in the response. If no error then you can either send an empty response (`{}`)
-or an empty value for the `Err` field. Errors will only be logged.

-# Engine network driver plugins
-
-This document describes Docker Engine network driver plugins generally
-available in Docker Engine. To view information on plugins
-managed by Docker Engine, refer to [Docker Engine plugin system](index.md).
-
-Docker Engine network plugins enable Engine deployments to be extended to
-support a wide range of networking technologies, such as VXLAN, IPVLAN, MACVLAN
-or something completely different. Network driver plugins are supported via the
-LibNetwork project. Each plugin is implemented as a  "remote driver" for
-LibNetwork, which shares plugin infrastructure with Engine. Effectively, network
-driver plugins are activated in the same way as other plugins, and use the same
-kind of protocol.
-
-## Network driver plugins and swarm mode
-
-Docker 1.12 adds support for cluster management and orchestration called
-[swarm mode](https://docs.docker.com/engine/swarm/). Docker Engine running in swarm mode currently
-only supports the built-in overlay driver for networking. Therefore existing
-networking plugins will not work in swarm mode.
-
-When you run Docker Engine outside of swarm mode, all networking plugins that
-worked in Docker 1.11 will continue to function normally. They do not require
-any modification.
-
-## Using network driver plugins
-
-The means of installing and running a network driver plugin depend on the
-particular plugin. So, be sure to install your plugin according to the
-instructions obtained from the plugin developer.
-
-Once running however, network driver plugins are used just like the built-in
-network drivers: by being mentioned as a driver in network-oriented Docker
-commands. For example,
-
-    $ docker network create --driver weave mynet
-
-Some network driver plugins are listed in [plugins](legacy_plugins.md)
-
-The `mynet` network is now owned by `weave`, so subsequent commands
-referring to that network will be sent to the plugin,
-
-    $ docker run --network=mynet busybox top
-
-
-## Write a network plugin
-
-Network plugins implement the [Docker plugin
-API](plugin_api.md) and the network plugin protocol
-
-## Network plugin protocol
-
-The network driver protocol, in addition to the plugin activation call, is
-documented as part of libnetwork:
-[https://github.com/docker/libnetwork/blob/master/docs/remote.md](https://github.com/docker/libnetwork/blob/master/docs/remote.md).
-
-# Related Information
-
-To interact with the Docker maintainers and other interested users, see the IRC channel `#docker-network`.

-# Using Volume and Network plugins in Docker services
-
-In swarm mode, it is possible to create a service that allows for attaching
-to networks or mounting volumes that are backed by plugins. Swarm schedules
-services based on plugin availability on a node.
-
-
-### Volume plugins
-
-In this example, a volume plugin is installed on a swarm worker and a volume
-is created using the plugin. In the manager, a service is created with the
-relevant mount options. It can be observed that the service is scheduled to
-run on the worker node with the said volume plugin and volume. Note that,
-node1 is the manager and node2 is the worker.
-
-1.  Prepare manager. In node 1:
-
-    ```bash
-    $ docker swarm init
-    Swarm initialized: current node (dxn1zf6l61qsb1josjja83ngz) is now a manager.
-    ```
-
-2. Join swarm, install plugin and create volume on worker. In node 2:
-
-    ```bash
-    $ docker swarm join \
-    --token SWMTKN-1-49nj1cmql0jkz5s954yi3oex3nedyz0fb0xx14ie39trti4wxv-8vxv8rssmk743ojnwacrr2e7c \
-    192.168.99.100:2377
-    ```
-
-    ```bash

-### Network plugins
-
-In this example, a global scope network plugin is installed on both the
-swarm manager and worker. A service is created with replicated instances
-using the installed plugin. We will observe how the availability of the
-plugin determines network creation and container scheduling.
-
-Note that node1 is the manager and node2 is the worker.
-
-
-1. Install a global scoped network plugin on both manager and worker. On node1
-   and node2:
-
-    ```bash
-    $ docker plugin install bboreham/weave2
-    Plugin "bboreham/weave2" is requesting the following privileges:
-    - network: [host]
-    - capabilities: [CAP_SYS_ADMIN CAP_NET_ADMIN]
-    Do you grant the above permissions? [y/N] y

-# Write a volume plugin
-
-Docker Engine volume plugins enable Engine deployments to be integrated with
-external storage systems such as Amazon EBS, and enable data volumes to persist
-beyond the lifetime of a single Docker host. See the
-[plugin documentation](legacy_plugins.md) for more information.
-
-## Changelog
-
-### 1.13.0
-
-- If used as part of the v2 plugin architecture, mountpoints that are part of
-  paths returned by the plugin must be mounted under the directory specified by
-  `PropagatedMount` in the plugin configuration
-  ([#26398](https://github.com/docker/docker/pull/26398))
-
-### 1.12.0
-
-- Add `Status` field to `VolumeDriver.Get` response
-  ([#21006](https://github.com/docker/docker/pull/21006#))
-- Add `VolumeDriver.Capabilities` to get capabilities of the volume driver
-  ([#22077](https://github.com/docker/docker/pull/22077))
-
-### 1.10.0
-
-- Add `VolumeDriver.Get` which gets the details about the volume
-  ([#16534](https://github.com/docker/docker/pull/16534))
-- Add `VolumeDriver.List` which lists all volumes owned by the driver
-  ([#16534](https://github.com/docker/docker/pull/16534))
-
-### 1.8.0
-
-- Initial support for volume driver plugins
-  ([#14659](https://github.com/docker/docker/pull/14659))
-
-## Command-line changes
-
-To give a container access to a volume, use the `--volume` and `--volume-driver`
-flags on the `docker container run` command.  The `--volume` (or `-v`) flag
-accepts a volume name and path on the host, and the `--volume-driver` flag
-accepts a driver type.
-
-```bash
-$ docker volume create --driver=flocker volumename
-
-$ docker container run -it --volume volumename:/data busybox sh
-```
-
-### `--volume`
-
-The `--volume` (or `-v`) flag takes a value that is in the format
-`<volume_name>:<mountpoint>`. The two parts of the value are
-separated by a colon (`:`) character.
-
-- The volume name is a human-readable name for the volume, and cannot begin with
-  a `/` character. It is referred to as `volume_name` in the rest of this topic.
-- The `Mountpoint` is the path on the host (v1) or in the plugin (v2) where the
-  volume has been made available.
-
-### `volumedriver`
-
-Specifying a `volumedriver` in conjunction with a `volumename` allows you to
-use plugins such as [Flocker](https://github.com/ScatterHQ/flocker) to manage
-volumes external to a single host, such as those on EBS.
-
-## Create a VolumeDriver
-
-The container creation endpoint (`/containers/create`) accepts a `VolumeDriver`
-field of type `string` allowing to specify the name of the driver. If not
-specified, it defaults to `"local"` (the default driver for local volumes).
-
-## Volume plugin protocol
-
-If a plugin registers itself as a `VolumeDriver` when activated, it must
-provide the Docker Daemon with writeable paths on the host filesystem. The Docker
-daemon provides these paths to containers to consume. The Docker daemon makes
-the volumes available by bind-mounting the provided paths into the containers.
-
-> **Note**: Volume plugins should *not* write data to the `/var/lib/docker/`
-> directory, including `/var/lib/docker/volumes`. The `/var/lib/docker/`
-> directory is reserved for Docker.
-
-### `/VolumeDriver.Create`
-
-**Request**:
-```json
-{
-    "Name": "volume_name",
-    "Opts": {}
-}
-```
-
-Instruct the plugin that the user wants to create a volume, given a user
-specified volume name. The plugin does not need to actually manifest the
-volume on the filesystem yet (until `Mount` is called).
-`Opts` is a map of driver specific options passed through from the user request.
-
-**Response**:
-```json
-{
-    "Err": ""
-}
-```
-
-Respond with a string error if an error occurred.
-
-### `/VolumeDriver.Remove`
-
-**Request**:
-```json
-{
-    "Name": "volume_name"
-}
-```
-
-Delete the specified volume from disk. This request is issued when a user
-invokes `docker rm -v` to remove volumes associated with a container.
-
-**Response**:
-```json
-{
-    "Err": ""
-}
-```
-
-Respond with a string error if an error occurred.
-
-### `/VolumeDriver.Mount`
-
-**Request**:
-```json
-{
-    "Name": "volume_name",
-    "ID": "b87d7442095999a92b65b3d9691e697b61713829cc0ffd1bb72e4ccd51aa4d6c"
-}
-```
-
-Docker requires the plugin to provide a volume, given a user specified volume
-name. `Mount` is called once per container start. If the same `volume_name` is requested
-more than once, the plugin may need to keep track of each new mount request and provision
-at the first mount request and deprovision at the last corresponding unmount request.
-
-`ID` is a unique ID for the caller that is requesting the mount.
-
-**Response**:
-
-- **v1**:
-
-  ```json
-  {
-      "Mountpoint": "/path/to/directory/on/host",
-      "Err": ""
-  }
-  ```
-
-- **v2**:
-
-  ```json
-  {
-      "Mountpoint": "/path/under/PropagatedMount",
-      "Err": ""
-  }
-  ```
-
-`Mountpoint` is the path on the host (v1) or in the plugin (v2) where the volume
-has been made available.
-
-`Err` is either empty or contains an error string.
-
-### `/VolumeDriver.Path`
-
-**Request**:
-
-```json
-{
-    "Name": "volume_name"
-}
-```
-
-Request the path to the volume with the given `volume_name`.
-
-**Response**:
-
-- **v1**:
-
-  ```json
-  {
-      "Mountpoin": "/path/to/directory/on/host",
-      "Err": ""
-  }
-  ```
-
-- **v2**:
-
-  ```json
-  {
-      "Mountpoint": "/path/under/PropagatedMount",
-      "Err": ""
-  }
-  ```
-
-Respond with the path on the host (v1) or inside the plugin (v2) where the
-volume has been made available, and/or a string error if an error occurred.
-
-`Mountpoint` is optional. However, the plugin may be queried again later if one
-is not provided.
-
-### `/VolumeDriver.Unmount`
-
-**Request**:
-```json
-{
-    "Name": "volume_name",
-    "ID": "b87d7442095999a92b65b3d9691e697b61713829cc0ffd1bb72e4ccd51aa4d6c"
-}
-```
-
-Docker is no longer using the named volume. `Unmount` is called once per
-container stop. Plugin may deduce that it is safe to deprovision the volume at
-this point.
-
-`ID` is a unique ID for the caller that is requesting the mount.
-
-**Response**:
-```json
-{
-    "Err": ""
-}
-```
-
-Respond with a string error if an error occurred.
-
-
-### `/VolumeDriver.Get`
-
-**Request**:
-```json
-{
-    "Name": "volume_name"
-}
-```
-
-Get info about `volume_name`.
-
-
-**Response**:
-
-- **v1**:
-
-  ```json
-  {
-    "Volume": {
-      "Name": "volume_name",
-      "Mountpoint": "/path/to/directory/on/host",
-      "Status": {}
-    },
-    "Err": ""
-  }
-  ```
-
-- **v2**:
-
-  ```json
-  {
-    "Volume": {
-      "Name": "volume_name",
-      "Mountpoint": "/path/under/PropagatedMount",
-      "Status": {}
-    },
-    "Err": ""
-  }
-  ```
-
-Respond with a string error if an error occurred. `Mountpoint` and `Status` are
-optional.
-
-
-### /VolumeDriver.List
-
-**Request**:
-```json
-{}
-```
-
-Get the list of volumes registered with the plugin.
-
-**Response**:
-
-- **v1**:
-
-  ```json
-  {
-    "Volumes": [
-      {
-        "Name": "volume_name",
-        "Mountpoint": "/path/to/directory/on/host"
-      }
-    ],
-    "Err": ""
-  }
-  ```
-
-- **v2**:
-
-  ```json
-  {
-    "Volumes": [
-      {
-        "Name": "volume_name",
-        "Mountpoint": "/path/under/PropagatedMount"
-      }
-    ],
-    "Err": ""

-
-**Response**:

-  "Capabilities": {
-    "Scope": "global"
-  }
-}
-```
-
-Supported scopes are `global` and `local`. Any other value in `Scope` will be
-ignored, and `local` is used. `Scope` allows cluster managers to handle the
-volume in different ways. For instance, a scope of `global`, signals to the
-cluster manager that it only needs to create the volume once instead of on each
-Docker host. More capabilities may be added in the future.

-# Dockerfile reference
-
-Docker can build images automatically by reading the instructions from a
-`Dockerfile`. A `Dockerfile` is a text document that contains all the commands a
-user could call on the command line to assemble an image. Using `docker build`
-users can create an automated build that executes several command-line
-instructions in succession.
-
-This page describes the commands you can use in a `Dockerfile`. When you are
-done reading this page, refer to the [`Dockerfile` Best
-Practices](https://docs.docker.com/engine/userguide/eng-image/dockerfile_best-practices/) for a tip-oriented guide.
-
-## Usage
-
-The [`docker build`](commandline/build.md) command builds an image from
-a `Dockerfile` and a *context*. The build's context is the files at a specified
-location `PATH` or `URL`. The `PATH` is a directory on your local filesystem.
-The `URL` is a Git repository location.
-
-A context is processed recursively. So, a `PATH` includes any subdirectories and
-the `URL` includes the repository and its submodules. A simple build command
-that uses the current directory as context:
-
-    $ docker build .
-    Sending build context to Docker daemon  6.51 MB
-    ...
-
-The build is run by the Docker daemon, not by the CLI. The first thing a build
-process does is send the entire context (recursively) to the daemon.  In most
-cases, it's best to start with an empty directory as context and keep your
-Dockerfile in that directory. Add only the files needed for building the
-Dockerfile.
-
->**Warning**: Do not use your root directory, `/`, as the `PATH` as it causes
->the build to transfer the entire contents of your hard drive to the Docker
->daemon.
-
-To use a file in the build context, the `Dockerfile` refers to the file specified
-in an instruction, for example,  a `COPY` instruction. To increase the build's
-performance, exclude files and directories by adding a `.dockerignore` file to
-the context directory.  For information about how to [create a `.dockerignore`
-file](#dockerignore-file) see the documentation on this page.
-
-Traditionally, the `Dockerfile` is called `Dockerfile` and located in the root
-of the context. You use the `-f` flag with `docker build` to point to a Dockerfile
-anywhere in your file system.
-
-    $ docker build -f /path/to/a/Dockerfile .
-
-You can specify a repository and tag at which to save the new image if
-the build succeeds:
-
-    $ docker build -t shykes/myapp .
-
-To tag the image into multiple repositories after the build,
-add multiple `-t` parameters when you run the `build` command:
-
-    $ docker build -t shykes/myapp:1.0.2 -t shykes/myapp:latest .
-
-Before the Docker daemon runs the instructions in the `Dockerfile`, it performs
-a preliminary validation of the `Dockerfile` and returns an error if the syntax is incorrect:
-
-    $ docker build -t test/myapp .
-    Sending build context to Docker daemon 2.048 kB
-    Error response from daemon: Unknown instruction: RUNCMD
-
-The Docker daemon runs the instructions in the `Dockerfile` one-by-one,
-committing the result of each instruction
-to a new image if necessary, before finally outputting the ID of your
-new image. The Docker daemon will automatically clean up the context you
-sent.
-
-Note that each instruction is run independently, and causes a new image
-to be created - so `RUN cd /tmp` will not have any effect on the next
-instructions.
-
-Whenever possible, Docker will re-use the intermediate images (cache),
-to accelerate the `docker build` process significantly. This is indicated by
-the `Using cache` message in the console output.
-(For more information, see the [Build cache section](https://docs.docker.com/engine/userguide/eng-image/dockerfile_best-practices/#build-cache) in the
-`Dockerfile` best practices guide):
-
-    $ docker build -t svendowideit/ambassador .

-
-Build cache is only used from images that have a local parent chain. This means
-that these images were created by previous builds or the whole chain of images
-was loaded with `docker load`. If you wish to use build cache of a specific
-image you can specify it with `--cache-from` option. Images specified with
-`--cache-from` do not need to have a parent chain and may be pulled from other
-registries.
-
-When you're done with your build, you're ready to look into [*Pushing a
-repository to its registry*](https://docs.docker.com/engine/tutorials/dockerrepos/#/contributing-to-docker-hub).
-
-## Format
-
-Here is the format of the `Dockerfile`:
-
-```Dockerfile
-# Comment
-INSTRUCTION arguments
-```
-
-The instruction is not case-sensitive. However, convention is for them to
-be UPPERCASE to distinguish them from arguments more easily.
-
-
-Docker runs instructions in a `Dockerfile` in order. A `Dockerfile` **must
-start with a \`FROM\` instruction**. The `FROM` instruction specifies the [*Base
-Image*](glossary.md#base-image) from which you are building. `FROM` may only be
-proceeded by one or more `ARG` instructions, which declare arguments that are used
-in `FROM` lines in the `Dockerfile`.
-
-Docker treats lines that *begin* with `#` as a comment, unless the line is
-a valid [parser directive](#parser-directives). A `#` marker anywhere
-else in a line is treated as an argument. This allows statements like:
-
-```Dockerfile
-# Comment
-RUN echo 'we are running some # of cool things'
-```
-
-Line continuation characters are not supported in comments.
-
-## Parser directives
-
-Parser directives are optional, and affect the way in which subsequent lines
-in a `Dockerfile` are handled. Parser directives do not add layers to the build,
-and will not be shown as a build step. Parser directives are written as a
-special type of comment in the form `# directive=value`. A single directive
-may only be used once.
-
-Once a comment, empty line or builder instruction has been processed, Docker
-no longer looks for parser directives. Instead it treats anything formatted
-as a parser directive as a comment and does not attempt to validate if it might
-be a parser directive. Therefore, all parser directives must be at the very
-top of a `Dockerfile`.
-
-Parser directives are not case-sensitive. However, convention is for them to
-be lowercase. Convention is also to include a blank line following any
-parser directives. Line continuation characters are not supported in parser
-directives.
-
-Due to these rules, the following examples are all invalid:
-
-Invalid due to line continuation:
-
-```Dockerfile
-# direc \
-tive=value
-```
-
-Invalid due to appearing twice:
-
-```Dockerfile
-# directive=value1
-# directive=value2
-
-FROM ImageName
-```
-
-Treated as a comment due to appearing after a builder instruction:
-
-```Dockerfile
-FROM ImageName
-# directive=value
-```
-
-Treated as a comment due to appearing after a comment which is not a parser
-directive:
-
-```Dockerfile
-# About my dockerfile
-# directive=value
-FROM ImageName
-```
-
-The unknown directive is treated as a comment due to not being recognized. In
-addition, the known directive is treated as a comment due to appearing after
-a comment which is not a parser directive.
-
-```Dockerfile
-# unknowndirective=value
-# knowndirective=value
-```
-
-Non line-breaking whitespace is permitted in a parser directive. Hence, the
-following lines are all treated identically:
-
-```Dockerfile
-#directive=value
-# directive =value
-#	directive= value
-# directive = value
-#	  dIrEcTiVe=value
-```
-
-The following parser directive is supported:
-
-* `escape`
-
-## escape
-
-    # escape=\ (backslash)
-
-Or
-
-    # escape=` (backtick)
-
-The `escape` directive sets the character used to escape characters in a
-`Dockerfile`. If not specified, the default escape character is `\`.
-
-The escape character is used both to escape characters in a line, and to
-escape a newline. This allows a `Dockerfile` instruction to
-span multiple lines. Note that regardless of whether the `escape` parser
-directive is included in a `Dockerfile`, *escaping is not performed in
-a `RUN` command, except at the end of a line.*
-
-Setting the escape character to `` ` `` is especially useful on
-`Windows`, where `\` is the directory path separator. `` ` `` is consistent
-with [Windows PowerShell](https://technet.microsoft.com/en-us/library/hh847755.aspx).
-
-Consider the following example which would fail in a non-obvious way on
-`Windows`. The second `\` at the end of the second line would be interpreted as an
-escape for the newline, instead of a target of the escape from the first `\`.
-Similarly, the `\` at the end of the third line would, assuming it was actually
-handled as an instruction, cause it be treated as a line continuation. The result
-of this dockerfile is that second and third lines are considered a single
-instruction:
-
-```Dockerfile
-FROM microsoft/nanoserver
-COPY testfile.txt c:\\
-RUN dir c:\
-```
-
-Results in:
-
-    PS C:\John> docker build -t cmd .
-    Sending build context to Docker daemon 3.072 kB
-    Step 1/2 : FROM microsoft/nanoserver
-     ---> 22738ff49c6d
-    Step 2/2 : COPY testfile.txt c:\RUN dir c:
-    GetFileAttributesEx c:RUN: The system cannot find the file specified.
-    PS C:\John>
-
-One solution to the above would be to use `/` as the target of both the `COPY`
-instruction, and `dir`. However, this syntax is, at best, confusing as it is not
-natural for paths on `Windows`, and at worst, error prone as not all commands on
-`Windows` support `/` as the path separator.
-
-By adding the `escape` parser directive, the following `Dockerfile` succeeds as
-expected with the use of natural platform semantics for file paths on `Windows`:
-
-    # escape=`
-
-    FROM microsoft/nanoserver
-    COPY testfile.txt c:\
-    RUN dir c:\
-
-Results in:
-
-    PS C:\John> docker build -t succeeds --no-cache=true .

-## Environment replacement
-
-Environment variables (declared with [the `ENV` statement](#env)) can also be
-used in certain instructions as variables to be interpreted by the
-`Dockerfile`. Escapes are also handled for including variable-like syntax
-into a statement literally.
-
-Environment variables are notated in the `Dockerfile` either with
-`$variable_name` or `${variable_name}`. They are treated equivalently and the
-brace syntax is typically used to address issues with variable names with no
-whitespace, like `${foo}_bar`.
-
-The `${variable_name}` syntax also supports a few of the standard `bash`
-modifiers as specified below:
-
-* `${variable:-word}` indicates that if `variable` is set then the result
-  will be that value. If `variable` is not set then `word` will be the result.
-* `${variable:+word}` indicates that if `variable` is set then `word` will be
-  the result, otherwise the result is the empty string.
-
-In all cases, `word` can be any string, including additional environment
-variables.
-
-Escaping is possible by adding a `\` before the variable: `\$foo` or `\${foo}`,
-for example, will translate to `$foo` and `${foo}` literals respectively.
-
-Example (parsed representation is displayed after the `#`):
-
-    FROM busybox
-    ENV foo /bar
-    WORKDIR ${foo}   # WORKDIR /bar
-    ADD . $foo       # ADD . /bar
-    COPY \$foo /quux # COPY $foo /quux
-
-Environment variables are supported by the following list of instructions in
-the `Dockerfile`:
-
-* `ADD`
-* `COPY`
-* `ENV`
-* `EXPOSE`
-* `FROM`
-* `LABEL`
-* `STOPSIGNAL`
-* `USER`
-* `VOLUME`
-* `WORKDIR`
-
-as well as:
-
-* `ONBUILD` (when combined with one of the supported instructions above)
-
-> **Note**:
-> prior to 1.4, `ONBUILD` instructions did **NOT** support environment
-> variable, even when combined with any of the instructions listed above.
-
-Environment variable substitution will use the same value for each variable
-throughout the entire instruction. In other words, in this example:
-
-    ENV abc=hello
-    ENV abc=bye def=$abc
-    ENV ghi=$abc
-
-will result in `def` having a value of `hello`, not `bye`. However,
-`ghi` will have a value of `bye` because it is not part of the same instruction 
-that set `abc` to `bye`.
-
-## .dockerignore file
-
-Before the docker CLI sends the context to the docker daemon, it looks
-for a file named `.dockerignore` in the root directory of the context.
-If this file exists, the CLI modifies the context to exclude files and
-directories that match patterns in it.  This helps to avoid
-unnecessarily sending large or sensitive files and directories to the
-daemon and potentially adding them to images using `ADD` or `COPY`.
-
-The CLI interprets the `.dockerignore` file as a newline-separated
-list of patterns similar to the file globs of Unix shells.  For the
-purposes of matching, the root of the context is considered to be both
-the working and the root directory.  For example, the patterns
-`/foo/bar` and `foo/bar` both exclude a file or directory named `bar`
-in the `foo` subdirectory of `PATH` or in the root of the git
-repository located at `URL`.  Neither excludes anything else.
-
-If a line in `.dockerignore` file starts with `#` in column 1, then this line is
-considered as a comment and is ignored before interpreted by the CLI.
-
-Here is an example `.dockerignore` file:
-
-```
-# comment
-*/temp*
-*/*/temp*
-temp?
-```
-
-This file causes the following build behavior:
-
-| Rule           | Behavior                                                                                                                                                                     |
-|----------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
-| `# comment`    | Ignored.                 |
-| `*/temp*`      | Exclude files and directories whose names start with `temp` in any immediate subdirectory of the root.  For example, the plain file `/somedir/temporary.txt` is excluded, as is the directory `/somedir/temp`.                 |
-| `*/*/temp*`    | Exclude files and directories starting with `temp` from any subdirectory that is two levels below the root. For example, `/somedir/subdir/temporary.txt` is excluded. |
-| `temp?`        | Exclude files and directories in the root directory whose names are a one-character extension of `temp`.  For example, `/tempa` and `/tempb` are excluded.
-
-
-Matching is done using Go's
-[filepath.Match](http://golang.org/pkg/path/filepath#Match) rules.  A
-preprocessing step removes leading and trailing whitespace and
-eliminates `.` and `..` elements using Go's
-[filepath.Clean](http://golang.org/pkg/path/filepath/#Clean).  Lines
-that are blank after preprocessing are ignored.
-
-Beyond Go's filepath.Match rules, Docker also supports a special
-wildcard string `**` that matches any number of directories (including
-zero). For example, `**/*.go` will exclude all files that end with `.go`
-that are found in all directories, including the root of the build context.
-
-Lines starting with `!` (exclamation mark) can be used to make exceptions
-to exclusions.  The following is an example `.dockerignore` file that
-uses this mechanism:
-
-```
-    *.md
-    !README.md
-```
-
-All markdown files *except* `README.md` are excluded from the context.
-
-The placement of `!` exception rules influences the behavior: the last
-line of the `.dockerignore` that matches a particular file determines
-whether it is included or excluded.  Consider the following example:
-
-```
-    *.md
-    !README*.md
-    README-secret.md
-```
-
-No markdown files are included in the context except README files other than
-`README-secret.md`.
-
-Now consider this example:
-
-```
-    *.md
-    README-secret.md
-    !README*.md
-```
-
-All of the README files are included.  The middle line has no effect because
-`!README*.md` matches `README-secret.md` and comes last.
-
-You can even use the `.dockerignore` file to exclude the `Dockerfile`
-and `.dockerignore` files.  These files are still sent to the daemon
-because it needs them to do its job.  But the `ADD` and `COPY` instructions
-do not copy them to the image.
-
-Finally, you may want to specify which files to include in the
-context, rather than which to exclude. To achieve this, specify `*` as
-the first pattern, followed by one or more `!` exception patterns.
-
-**Note**: For historical reasons, the pattern `.` is ignored.
-
-## FROM
-
-    FROM <image> [AS <name>]
-
-Or
-
-    FROM <image>[:<tag>] [AS <name>]
-
-Or
-
-    FROM <image>[@<digest>] [AS <name>]
-
-The `FROM` instruction initializes a new build stage and sets the 
-[*Base Image*](glossary.md#base-image) for subsequent instructions. As such, a 
-valid `Dockerfile` must start with a `FROM` instruction. The image can be
-any valid image – it is especially easy to start by **pulling an image** from 
-the [*Public Repositories*](https://docs.docker.com/engine/tutorials/dockerrepos/).
-
-- `ARG` is the only instruction that may proceed `FROM` in the `Dockerfile`. 
-  See [Understand how ARG and FROM interact](#understand-how-arg-and-from-interact).
-
-- `FROM` can appear multiple times within a single `Dockerfile` to 
-  create multiple images or use one build stage as a dependency for another.
-  Simply make a note of the last image ID output by the commit before each new 
-  `FROM` instruction. Each `FROM` instruction clears any state created by previous
-  instructions.
-
-- Optionally a name can be given to a new build stage by adding `AS name` to the 
-  `FROM` instruction. The name can be used in subsequent `FROM` and
-  `COPY --from=<name|index>` instructions to refer to the image built in this stage.
-
-- The `tag` or `digest` values are optional. If you omit either of them, the 
-  builder assumes a `latest` tag by default. The builder returns an error if it
-  cannot find the `tag` value.
-
-### Understand how ARG and FROM interact
-
-`FROM` instructions support variables that are declared by any `ARG` 
-instructions that occur before the first `FROM`.
-
-```Dockerfile
-ARG  CODE_VERSION=latest
-FROM base:${CODE_VERSION}
-CMD  /code/run-app
-
-FROM extras:${CODE_VERSION}
-CMD  /code/run-extras
-```
-
-To use the default value of an `ARG` declared before the first `FROM` use an
-`ARG` instruction without a value:
-
-```Dockerfile
-ARG  SETTINGS=default
-
-FROM busybox
-ARG  SETTINGS
-
-```
-
-## RUN
-
-RUN has 2 forms:
-
-- `RUN <command>` (*shell* form, the command is run in a shell, which by
-default is `/bin/sh -c` on Linux or `cmd /S /C` on Windows)
-- `RUN ["executable", "param1", "param2"]` (*exec* form)
-
-The `RUN` instruction will execute any commands in a new layer on top of the
-current image and commit the results. The resulting committed image will be
-used for the next step in the `Dockerfile`.
-
-Layering `RUN` instructions and generating commits conforms to the core
-concepts of Docker where commits are cheap and containers can be created from
-any point in an image's history, much like source control.
-
-The *exec* form makes it possible to avoid shell string munging, and to `RUN`
-commands using a base image that does not contain the specified shell executable.
-
-The default shell for the *shell* form can be changed using the `SHELL`
-command.
-
-In the *shell* form you can use a `\` (backslash) to continue a single
-RUN instruction onto the next line. For example, consider these two lines:
-
-```
-RUN /bin/bash -c 'source $HOME/.bashrc; \
-echo $HOME'
-```
-Together they are equivalent to this single line:
-
-```
-RUN /bin/bash -c 'source $HOME/.bashrc; echo $HOME'
-```
-
-> **Note**:
-> To use a different shell, other than '/bin/sh', use the *exec* form
-> passing in the desired shell. For example,
-> `RUN ["/bin/bash", "-c", "echo hello"]`
-
-> **Note**:
-> The *exec* form is parsed as a JSON array, which means that
-> you must use double-quotes (") around words not single-quotes (').
-
-> **Note**:
-> Unlike the *shell* form, the *exec* form does not invoke a command shell.
-> This means that normal shell processing does not happen. For example,
-> `RUN [ "echo", "$HOME" ]` will not do variable substitution on `$HOME`.
-> If you want shell processing then either use the *shell* form or execute
-> a shell directly, for example: `RUN [ "sh", "-c", "echo $HOME" ]`.
-> When using the exec form and executing a shell directly, as in the case for
-> the shell form, it is the shell that is doing the environment variable
-> expansion, not docker.
->
-> **Note**:
-> In the *JSON* form, it is necessary to escape backslashes. This is
-> particularly relevant on Windows where the backslash is the path separator.
-> The following line would otherwise be treated as *shell* form due to not
-> being valid JSON, and fail in an unexpected way:
-> `RUN ["c:\windows\system32\tasklist.exe"]`
-> The correct syntax for this example is:
-> `RUN ["c:\\windows\\system32\\tasklist.exe"]`
-
-The cache for `RUN` instructions isn't invalidated automatically during
-the next build. The cache for an instruction like
-`RUN apt-get dist-upgrade -y` will be reused during the next build. The
-cache for `RUN` instructions can be invalidated by using the `--no-cache`
-flag, for example `docker build --no-cache`.

-### Known issues (RUN)
-
-- [Issue 783](https://github.com/docker/docker/issues/783) is about file
-  permissions problems that can occur when using the AUFS file system. You
-  might notice it during an attempt to `rm` a file, for example.
-
-  For systems that have recent aufs version (i.e., `dirperm1` mount option can
-  be set), docker will attempt to fix the issue automatically by mounting
-  the layers with `dirperm1` option. More details on `dirperm1` option can be
-  found at [`aufs` man page](https://github.com/sfjro/aufs3-linux/tree/aufs3.18/Documentation/filesystems/aufs)
-
-  If your system doesn't have support for `dirperm1`, the issue describes a workaround.
-
-## CMD
-
-The `CMD` instruction has three forms:
-
-- `CMD ["executable","param1","param2"]` (*exec* form, this is the preferred form)
-- `CMD ["param1","param2"]` (as *default parameters to ENTRYPOINT*)
-- `CMD command param1 param2` (*shell* form)
-
-There can only be one `CMD` instruction in a `Dockerfile`. If you list more than one `CMD`
-then only the last `CMD` will take effect.
-
-**The main purpose of a `CMD` is to provide defaults for an executing
-container.** These defaults can include an executable, or they can omit
-the executable, in which case you must specify an `ENTRYPOINT`
-instruction as well.
-
-> **Note**:
-> If `CMD` is used to provide default arguments for the `ENTRYPOINT`
-> instruction, both the `CMD` and `ENTRYPOINT` instructions should be specified
-> with the JSON array format.
-
-> **Note**:
-> The *exec* form is parsed as a JSON array, which means that
-> you must use double-quotes (") around words not single-quotes (').
-
-> **Note**:
-> Unlike the *shell* form, the *exec* form does not invoke a command shell.
-> This means that normal shell processing does not happen. For example,
-> `CMD [ "echo", "$HOME" ]` will not do variable substitution on `$HOME`.
-> If you want shell processing then either use the *shell* form or execute
-> a shell directly, for example: `CMD [ "sh", "-c", "echo $HOME" ]`.
-> When using the exec form and executing a shell directly, as in the case for
-> the shell form, it is the shell that is doing the environment variable
-> expansion, not docker.
-
-When used in the shell or exec formats, the `CMD` instruction sets the command
-to be executed when running the image.
-
-If you use the *shell* form of the `CMD`, then the `<command>` will execute in
-`/bin/sh -c`:
-
-    FROM ubuntu
-    CMD echo "This is a test." | wc -
-
-If you want to **run your** `<command>` **without a shell** then you must
-express the command as a JSON array and give the full path to the executable.
-**This array form is the preferred format of `CMD`.** Any additional parameters
-must be individually expressed as strings in the array:
-
-    FROM ubuntu
-    CMD ["/usr/bin/wc","--help"]
-
-If you would like your container to run the same executable every time, then
-you should consider using `ENTRYPOINT` in combination with `CMD`. See
-[*ENTRYPOINT*](#entrypoint).
-
-If the user specifies arguments to `docker run` then they will override the
-default specified in `CMD`.
-
-> **Note**:
-> Don't confuse `RUN` with `CMD`. `RUN` actually runs a command and commits
-> the result; `CMD` does not execute anything at build time, but specifies
-> the intended command for the image.
-
-## LABEL
-
-    LABEL <key>=<value> <key>=<value> <key>=<value> ...
-
-The `LABEL` instruction adds metadata to an image. A `LABEL` is a
-key-value pair. To include spaces within a `LABEL` value, use quotes and
-backslashes as you would in command-line parsing. A few usage examples:
-
-    LABEL "com.example.vendor"="ACME Incorporated"
-    LABEL com.example.label-with-value="foo"
-    LABEL version="1.0"
-    LABEL description="This text illustrates \
-    that label-values can span multiple lines."
-
-An image can have more than one label. To specify multiple labels,
-Docker recommends combining labels into a single `LABEL` instruction where
-possible. Each `LABEL` instruction produces a new layer which can result in an
-inefficient image if you use many labels. This example results in a single image
-layer.
-
-    LABEL multi.label1="value1" multi.label2="value2" other="value3"
-
-The above can also be written as:
-
-    LABEL multi.label1="value1" \
-          multi.label2="value2" \
-          other="value3"
-
-Labels are additive including `LABEL`s in `FROM` images. If Docker
-encounters a label/key that already exists, the new value overrides any previous
-labels with identical keys.
-
-To view an image's labels, use the `docker inspect` command.
-
-    "Labels": {
-        "com.example.vendor": "ACME Incorporated"
-        "com.example.label-with-value": "foo",
-        "version": "1.0",
-        "description": "This text illustrates that label-values can span multiple lines.",
-        "multi.label1": "value1",
-        "multi.label2": "value2",
-        "other": "value3"
-    },
-
-## MAINTAINER (deprecated)
-
-    MAINTAINER <name>
-
-The `MAINTAINER` instruction sets the *Author* field of the generated images.
-The `LABEL` instruction is a much more flexible version of this and you should use
-it instead, as it enables setting any metadata you require, and can be viewed
-easily, for example with `docker inspect`. To set a label corresponding to the
-`MAINTAINER` field you could use:
-
-    LABEL maintainer="SvenDowideit@home.org.au"
-
-This will then be visible from `docker inspect` with the other labels.
-
-## EXPOSE
-
-    EXPOSE <port> [<port>...]
-
-The `EXPOSE` instruction informs Docker that the container listens on the
-specified network ports at runtime. `EXPOSE` does not make the ports of the
-container accessible to the host. To do that, you must use either the `-p` flag
-to publish a range of ports or the `-P` flag to publish all of the exposed
-ports. You can expose one port number and publish it externally under another
-number.
-
-To set up port redirection on the host system, see [using the -P
-flag](run.md#expose-incoming-ports). The Docker network feature supports
-creating networks without the need to expose ports within the network, for
-detailed information see the  [overview of this
-feature](https://docs.docker.com/engine/userguide/networking/)).
-
-## ENV
-
-    ENV <key> <value>
-    ENV <key>=<value> ...
-
-The `ENV` instruction sets the environment variable `<key>` to the value
-`<value>`. This value will be in the environment of all "descendant"
-`Dockerfile` commands and can be [replaced inline](#environment-replacement) in
-many as well.
-
-The `ENV` instruction has two forms. The first form, `ENV <key> <value>`,
-will set a single variable to a value. The entire string after the first
-space will be treated as the `<value>` - including characters such as
-spaces and quotes.
-
-The second form, `ENV <key>=<value> ...`, allows for multiple variables to
-be set at one time. Notice that the second form uses the equals sign (=)
-in the syntax, while the first form does not. Like command line parsing,
-quotes and backslashes can be used to include spaces within values.
-
-For example:
-
-    ENV myName="John Doe" myDog=Rex\ The\ Dog \
-        myCat=fluffy
-
-and
-
-    ENV myName John Doe
-    ENV myDog Rex The Dog
-    ENV myCat fluffy
-
-will yield the same net results in the final image, but the first form
-is preferred because it produces a single cache layer.
-
-The environment variables set using `ENV` will persist when a container is run
-from the resulting image. You can view the values using `docker inspect`, and
-change them using `docker run --env <key>=<value>`.
-
-> **Note**:
-> Environment persistence can cause unexpected side effects. For example,
-> setting `ENV DEBIAN_FRONTEND noninteractive` may confuse apt-get
-> users on a Debian-based image. To set a value for a single command, use
-> `RUN <key>=<value> <command>`.
-
-## ADD
-
-ADD has two forms:
-
-- `ADD <src>... <dest>`
-- `ADD ["<src>",... "<dest>"]` (this form is required for paths containing
-whitespace)
-
-The `ADD` instruction copies new files, directories or remote file URLs from `<src>`
-and adds them to the filesystem of the image at the path `<dest>`.
-
-Multiple `<src>` resource may be specified but if they are files or
-directories then they must be relative to the source directory that is
-being built (the context of the build).
-
-Each `<src>` may contain wildcards and matching will be done using Go's
-[filepath.Match](http://golang.org/pkg/path/filepath#Match) rules. For example:
-
-    ADD hom* /mydir/        # adds all files starting with "hom"
-    ADD hom?.txt /mydir/    # ? is replaced with any single character, e.g., "home.txt"
-
-The `<dest>` is an absolute path, or a path relative to `WORKDIR`, into which
-the source will be copied inside the destination container.
-
-    ADD test relativeDir/          # adds "test" to `WORKDIR`/relativeDir/
-    ADD test /absoluteDir/         # adds "test" to /absoluteDir/
-
-When adding files or directories that contain special characters (such as `[`
-and `]`), you need to escape those paths following the Golang rules to prevent
-them from being treated as a matching pattern. For example, to add a file
-named `arr[0].txt`, use the following;
-
-    ADD arr[[]0].txt /mydir/    # copy a file named "arr[0].txt" to /mydir/
-
-
-All new files and directories are created with a UID and GID of 0.
-
-In the case where `<src>` is a remote file URL, the destination will
-have permissions of 600. If the remote file being retrieved has an HTTP
-`Last-Modified` header, the timestamp from that header will be used
-to set the `mtime` on the destination file. However, like any other file
-processed during an `ADD`, `mtime` will not be included in the determination
-of whether or not the file has changed and the cache should be updated.
-
-> **Note**:
-> If you build by passing a `Dockerfile` through STDIN (`docker
-> build - < somefile`), there is no build context, so the `Dockerfile`
-> can only contain a URL based `ADD` instruction. You can also pass a
-> compressed archive through STDIN: (`docker build - < archive.tar.gz`),
-> the `Dockerfile` at the root of the archive and the rest of the
-> archive will be used as the context of the build.
-
-> **Note**:
-> If your URL files are protected using authentication, you
-> will need to use `RUN wget`, `RUN curl` or use another tool from
-> within the container as the `ADD` instruction does not support
-> authentication.
-
-> **Note**:
-> The first encountered `ADD` instruction will invalidate the cache for all
-> following instructions from the Dockerfile if the contents of `<src>` have
-> changed. This includes invalidating the cache for `RUN` instructions.
-> See the [`Dockerfile` Best Practices
-guide](https://docs.docker.com/engine/userguide/eng-image/dockerfile_best-practices/#/build-cache) for more information.
-
-
-`ADD` obeys the following rules:
-
-- The `<src>` path must be inside the *context* of the build;
-  you cannot `ADD ../something /something`, because the first step of a
-  `docker build` is to send the context directory (and subdirectories) to the
-  docker daemon.
-
-- If `<src>` is a URL and `<dest>` does not end with a trailing slash, then a
-  file is downloaded from the URL and copied to `<dest>`.
-
-- If `<src>` is a URL and `<dest>` does end with a trailing slash, then the
-  filename is inferred from the URL and the file is downloaded to
-  `<dest>/<filename>`. For instance, `ADD http://example.com/foobar /` would
-  create the file `/foobar`. The URL must have a nontrivial path so that an
-  appropriate filename can be discovered in this case (`http://example.com`
-  will not work).
-
-- If `<src>` is a directory, the entire contents of the directory are copied,
-  including filesystem metadata.
-
-> **Note**:
-> The directory itself is not copied, just its contents.
-
-- If `<src>` is a *local* tar archive in a recognized compression format
-  (identity, gzip, bzip2 or xz) then it is unpacked as a directory. Resources
-  from *remote* URLs are **not** decompressed. When a directory is copied or
-  unpacked, it has the same behavior as `tar -x`, the result is the union of:
-
-    1. Whatever existed at the destination path and
-    2. The contents of the source tree, with conflicts resolved in favor
-       of "2." on a file-by-file basis.
-
-  > **Note**:
-  > Whether a file is identified as a recognized compression format or not
-  > is done solely based on the contents of the file, not the name of the file.
-  > For example, if an empty file happens to end with `.tar.gz` this will not
-  > be recognized as a compressed file and **will not** generate any kind of
-  > decompression error message, rather the file will simply be copied to the
-  > destination.
-
-- If `<src>` is any other kind of file, it is copied individually along with
-  its metadata. In this case, if `<dest>` ends with a trailing slash `/`, it
-  will be considered a directory and the contents of `<src>` will be written
-  at `<dest>/base(<src>)`.
-
-- If multiple `<src>` resources are specified, either directly or due to the
-  use of a wildcard, then `<dest>` must be a directory, and it must end with
-  a slash `/`.
-
-- If `<dest>` does not end with a trailing slash, it will be considered a
-  regular file and the contents of `<src>` will be written at `<dest>`.
-
-- If `<dest>` doesn't exist, it is created along with all missing directories
-  in its path.
-
-## COPY
-
-COPY has two forms:
-
-- `COPY <src>... <dest>`
-- `COPY ["<src>",... "<dest>"]` (this form is required for paths containing
-whitespace)
-
-The `COPY` instruction copies new files or directories from `<src>`
-and adds them to the filesystem of the container at the path `<dest>`.
-
-Multiple `<src>` resource may be specified but they must be relative
-to the source directory that is being built (the context of the build).
-
-Each `<src>` may contain wildcards and matching will be done using Go's
-[filepath.Match](http://golang.org/pkg/path/filepath#Match) rules. For example:
-
-    COPY hom* /mydir/        # adds all files starting with "hom"
-    COPY hom?.txt /mydir/    # ? is replaced with any single character, e.g., "home.txt"
-
-The `<dest>` is an absolute path, or a path relative to `WORKDIR`, into which
-the source will be copied inside the destination container.
-
-    COPY test relativeDir/   # adds "test" to `WORKDIR`/relativeDir/
-    COPY test /absoluteDir/  # adds "test" to /absoluteDir/
-
-
-When copying files or directories that contain special characters (such as `[`
-and `]`), you need to escape those paths following the Golang rules to prevent
-them from being treated as a matching pattern. For example, to copy a file
-named `arr[0].txt`, use the following;
-
-    COPY arr[[]0].txt /mydir/    # copy a file named "arr[0].txt" to /mydir/
-
-All new files and directories are created with a UID and GID of 0.
-
-> **Note**:
-> If you build using STDIN (`docker build - < somefile`), there is no
-> build context, so `COPY` can't be used.
-
-Optionally `COPY` accepts a flag `--from=<name|index>` that can be used to set
-the source location to a previous build stage (created with `FROM .. AS <name>`)
-that will be used instead of a build context sent by the user. The flag also 
-accepts a numeric index assigned for all previous build stages started with 
-`FROM` instruction. In case a build stage with a specified name can't be found an 
-image with the same name is attempted to be used instead.
-
-`COPY` obeys the following rules:
-
-- The `<src>` path must be inside the *context* of the build;
-  you cannot `COPY ../something /something`, because the first step of a
-  `docker build` is to send the context directory (and subdirectories) to the
-  docker daemon.

-  regular file and the contents of `<src>` will be written at `<dest>`.
-
-- If `<dest>` doesn't exist, it is created along with all missing directories
-  in its path.
-
-## ENTRYPOINT
-
-ENTRYPOINT has two forms:
-
-- `ENTRYPOINT ["executable", "param1", "param2"]`
-  (*exec* form, preferred)
-- `ENTRYPOINT command param1 param2`
-  (*shell* form)
-
-An `ENTRYPOINT` allows you to configure a container that will run as an executable.
-
-For example, the following will start nginx with its default content, listening
-on port 80:
-
-    docker run -i -t --rm -p 80:80 nginx
-
-Command line arguments to `docker run <image>` will be appended after all
-elements in an *exec* form `ENTRYPOINT`, and will override all elements specified
-using `CMD`.
-This allows arguments to be passed to the entry point, i.e., `docker run <image> -d`
-will pass the `-d` argument to the entry point.
-You can override the `ENTRYPOINT` instruction using the `docker run --entrypoint`
-flag.
-
-The *shell* form prevents any `CMD` or `run` command line arguments from being
-used, but has the disadvantage that your `ENTRYPOINT` will be started as a
-subcommand of `/bin/sh -c`, which does not pass signals.
-This means that the executable will not be the container's `PID 1` - and
-will _not_ receive Unix signals - so your executable will not receive a
-`SIGTERM` from `docker stop <container>`.
-
-Only the last `ENTRYPOINT` instruction in the `Dockerfile` will have an effect.
-
-### Exec form ENTRYPOINT example
-
-You can use the *exec* form of `ENTRYPOINT` to set fairly stable default commands
-and arguments and then use either form of `CMD` to set additional defaults that
-are more likely to be changed.
-
-    FROM ubuntu
-    ENTRYPOINT ["top", "-b"]
-    CMD ["-c"]
-
-When you run the container, you can see that `top` is the only process:
-
-    $ docker run -it --rm --name test  top -H
-    top - 08:25:00 up  7:27,  0 users,  load average: 0.00, 0.01, 0.05
-    Threads:   1 total,   1 running,   0 sleeping,   0 stopped,   0 zombie
-    %Cpu(s):  0.1 us,  0.1 sy,  0.0 ni, 99.7 id,  0.0 wa,  0.0 hi,  0.0 si,  0.0 st
-    KiB Mem:   2056668 total,  1616832 used,   439836 free,    99352 buffers
-    KiB Swap:  1441840 total,        0 used,  1441840 free.  1324440 cached Mem
-
-      PID USER      PR  NI    VIRT    RES    SHR S %CPU %MEM     TIME+ COMMAND
-        1 root      20   0   19744   2336   2080 R  0.0  0.1   0:00.04 top
-
-To examine the result further, you can use `docker exec`:
-
-    $ docker exec -it test ps aux
-    USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
-    root         1  2.6  0.1  19752  2352 ?        Ss+  08:24   0:00 top -b -H
-    root         7  0.0  0.1  15572  2164 ?        R+   08:25   0:00 ps aux
-
-And you can gracefully request `top` to shut down using `docker stop test`.
-
-The following `Dockerfile` shows using the `ENTRYPOINT` to run Apache in the
-foreground (i.e., as `PID 1`):
-
-```
-FROM debian:stable
-RUN apt-get update && apt-get install -y --force-yes apache2
-EXPOSE 80 443
-VOLUME ["/var/www", "/var/log/apache2", "/etc/apache2"]
-ENTRYPOINT ["/usr/sbin/apache2ctl", "-D", "FOREGROUND"]
-```
-
-If you need to write a starter script for a single executable, you can ensure that
-the final executable receives the Unix signals by using `exec` and `gosu`
-commands:
-
-```bash
-#!/usr/bin/env bash
-set -e
-
-if [ "$1" = 'postgres' ]; then
-    chown -R postgres "$PGDATA"
-
-    if [ -z "$(ls -A "$PGDATA")" ]; then
-        gosu postgres initdb
-    fi
-
-    exec gosu postgres "$@"
-fi
-
-exec "$@"
-```
-
-Lastly, if you need to do some extra cleanup (or communicate with other containers)
-on shutdown, or are co-ordinating more than one executable, you may need to ensure
-that the `ENTRYPOINT` script receives the Unix signals, passes them on, and then
-does some more work:
-
-```
-#!/bin/sh
-# Note: I've written this using sh so it works in the busybox container too
-
-# USE the trap if you need to also do manual cleanup after the service is stopped,
-#     or need to start multiple services in the one container
-trap "echo TRAPed signal" HUP INT QUIT TERM
-
-# start service in background here
-/usr/sbin/apachectl start
-
-echo "[hit enter key to exit] or run 'docker stop <container>'"
-read
-
-# stop service and clean up here
-echo "stopping apache"
-/usr/sbin/apachectl stop
-
-echo "exited $0"
-```
-
-If you run this image with `docker run -it --rm -p 80:80 --name test apache`,
-you can then examine the container's processes with `docker exec`, or `docker top`,
-and then ask the script to stop Apache:
-
-```bash
-$ docker exec -it test ps aux
-USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
-root         1  0.1  0.0   4448   692 ?        Ss+  00:42   0:00 /bin/sh /run.sh 123 cmd cmd2

-sys	0m 0.03s
-```
-
-> **Note:** you can override the `ENTRYPOINT` setting using `--entrypoint`,
-> but this can only set the binary to *exec* (no `sh -c` will be used).
-
-> **Note**:
-> The *exec* form is parsed as a JSON array, which means that
-> you must use double-quotes (") around words not single-quotes (').
-
-> **Note**:
-> Unlike the *shell* form, the *exec* form does not invoke a command shell.
-> This means that normal shell processing does not happen. For example,
-> `ENTRYPOINT [ "echo", "$HOME" ]` will not do variable substitution on `$HOME`.

-
-### Shell form ENTRYPOINT example
-
-You can specify a plain string for the `ENTRYPOINT` and it will execute in `/bin/sh -c`.
-This form will use shell processing to substitute shell environment variables,
-and will ignore any `CMD` or `docker run` command line arguments.
-To ensure that `docker stop` will signal any long running `ENTRYPOINT` executable
-correctly, you need to remember to start it with `exec`:
-
-    FROM ubuntu
-    ENTRYPOINT exec top -b
-
-When you run this image, you'll see the single `PID 1` process:
-
-    $ docker run -it --rm --name test top
-    Mem: 1704520K used, 352148K free, 0K shrd, 0K buff, 140368121167873K cached
-    CPU:   5% usr   0% sys   0% nic  94% idle   0% io   0% irq   0% sirq
-    Load average: 0.08 0.03 0.05 2/98 6
-      PID  PPID USER     STAT   VSZ %VSZ %CPU COMMAND
-        1     0 root     R     3164   0%   0% top -b
-
-Which will exit cleanly on `docker stop`:
-
-    $ /usr/bin/time docker stop test
-    test
-    real	0m 0.20s
-    user	0m 0.02s
-    sys	0m 0.04s
-
-If you forget to add `exec` to the beginning of your `ENTRYPOINT`:
-
-    FROM ubuntu
-    ENTRYPOINT top -b
-    CMD --ignored-param1
-
-You can then run it (giving it a name for the next step):
-
-    $ docker run -it --name test top --ignored-param2
-    Mem: 1704184K used, 352484K free, 0K shrd, 0K buff, 140621524238337K cached
-    CPU:   9% usr   2% sys   0% nic  88% idle   0% io   0% irq   0% sirq
-    Load average: 0.01 0.02 0.05 2/101 7
-      PID  PPID USER     STAT   VSZ %VSZ %CPU COMMAND
-        1     0 root     S     3168   0%   0% /bin/sh -c top -b cmd cmd2
-        7     1 root     R     3164   0%   0% top -b
-
-You can see from the output of `top` that the specified `ENTRYPOINT` is not `PID 1`.
-
-If you then run `docker stop test`, the container will not exit cleanly - the
-`stop` command will be forced to send a `SIGKILL` after the timeout:
-
-    $ docker exec -it test ps aux
-    PID   USER     COMMAND
-        1 root     /bin/sh -c top -b cmd cmd2
-        7 root     top -b
-        8 root     ps aux
-    $ /usr/bin/time docker stop test
-    test
-    real	0m 10.19s
-    user	0m 0.04s
-    sys	0m 0.03s
-
-### Understand how CMD and ENTRYPOINT interact
-
-Both `CMD` and `ENTRYPOINT` instructions define what command gets executed when running a container.
-There are few rules that describe their co-operation.
-
-1. Dockerfile should specify at least one of `CMD` or `ENTRYPOINT` commands.
-
-2. `ENTRYPOINT` should be defined when using the container as an executable.
-
-3. `CMD` should be used as a way of defining default arguments for an `ENTRYPOINT` command
-or for executing an ad-hoc command in a container.
-
-4. `CMD` will be overridden when running the container with alternative arguments.
-
-The table below shows what command is executed for different `ENTRYPOINT` / `CMD` combinations:
-
-|                                | No ENTRYPOINT              | ENTRYPOINT exec_entry p1_entry | ENTRYPOINT ["exec_entry", "p1_entry"]          |
-|--------------------------------|----------------------------|--------------------------------|------------------------------------------------|
-| **No CMD**                     | *error, not allowed*       | /bin/sh -c exec_entry p1_entry | exec_entry p1_entry                            |
-| **CMD ["exec_cmd", "p1_cmd"]** | exec_cmd p1_cmd            | /bin/sh -c exec_entry p1_entry | exec_entry p1_entry exec_cmd p1_cmd            |
-| **CMD ["p1_cmd", "p2_cmd"]**   | p1_cmd p2_cmd              | /bin/sh -c exec_entry p1_entry | exec_entry p1_entry p1_cmd p2_cmd              |
-| **CMD exec_cmd p1_cmd**        | /bin/sh -c exec_cmd p1_cmd | /bin/sh -c exec_entry p1_entry | exec_entry p1_entry /bin/sh -c exec_cmd p1_cmd |
-
-## VOLUME
-
-    VOLUME ["/data"]
-
-The `VOLUME` instruction creates a mount point with the specified name
-and marks it as holding externally mounted volumes from native host or other
-containers. The value can be a JSON array, `VOLUME ["/var/log/"]`, or a plain
-string with multiple arguments, such as `VOLUME /var/log` or `VOLUME /var/log
-/var/db`. For more information/examples and mounting instructions via the
-Docker client, refer to
-[*Share Directories via Volumes*](https://docs.docker.com/engine/tutorials/dockervolumes/#/mount-a-host-directory-as-a-data-volume)
-documentation.
-
-The `docker run` command initializes the newly created volume with any data
-that exists at the specified location within the base image. For example,
-consider the following Dockerfile snippet:
-
-    FROM ubuntu
-    RUN mkdir /myvol
-    RUN echo "hello world" > /myvol/greeting
-    VOLUME /myvol
-
-This Dockerfile results in an image that causes `docker run`, to
-create a new mount point at `/myvol` and copy the  `greeting` file
-into the newly created volume.
-
-### Notes about specifying volumes
-
-Keep the following things in mind about volumes in the `Dockerfile`.
-
-- **Volumes on Windows-based containers**: When using Windows-based containers,
-  the destination of a volume inside the container must be one of:
-  
-  - a non-existing or empty directory
-  - a drive other than `C:`
-
-- **Changing the volume from within the Dockerfile**: If any build steps change the
-  data within the volume after it has been declared, those changes will be discarded.
-
-- **JSON formatting**: The list is parsed as a JSON array.
-  You must enclose words with double quotes (`"`)rather than single quotes (`'`).
-
-- **The host directory is declared at container run-time**: The host directory
-  (the mountpoint) is, by its nature, host-dependent. This is to preserve image
-  portability. since a given host directory can't be guaranteed to be available
-  on all hosts.For this reason, you can't mount a host directory from
-  within the Dockerfile. The `VOLUME` instruction does not support specifying a `host-dir`
-  parameter.  You must specify the mountpoint when you create or run the container.
-
-## USER
-
-    USER daemon
-
-The `USER` instruction sets the user name or UID to use when running the image
-and for any `RUN`, `CMD` and `ENTRYPOINT` instructions that follow it in the
-`Dockerfile`.
-
-## WORKDIR
-
-    WORKDIR /path/to/workdir
-
-The `WORKDIR` instruction sets the working directory for any `RUN`, `CMD`,
-`ENTRYPOINT`, `COPY` and `ADD` instructions that follow it in the `Dockerfile`.
-If the `WORKDIR` doesn't exist, it will be created even if it's not used in any
-subsequent `Dockerfile` instruction.
-
-It can be used multiple times in the one `Dockerfile`. If a relative path
-is provided, it will be relative to the path of the previous `WORKDIR`
-instruction. For example:
-
-    WORKDIR /a
-    WORKDIR b
-    WORKDIR c
-    RUN pwd
-
-The output of the final `pwd` command in this `Dockerfile` would be
-`/a/b/c`.
-
-The `WORKDIR` instruction can resolve environment variables previously set using
-`ENV`. You can only use environment variables explicitly set in the `Dockerfile`.
-For example:
-
-    ENV DIRPATH /path
-    WORKDIR $DIRPATH/$DIRNAME
-    RUN pwd
-
-The output of the final `pwd` command in this `Dockerfile` would be
-`/path/$DIRNAME`
-
-## ARG
-
-    ARG <name>[=<default value>]
-
-The `ARG` instruction defines a variable that users can pass at build-time to
-the builder with the `docker build` command using the `--build-arg <varname>=<value>`
-flag. If a user specifies a build argument that was not
-defined in the Dockerfile, the build outputs a warning.
-
-```
-[Warning] One or more build-args [foo] were not consumed.
-```
-
-The Dockerfile author can define a single variable by specifying `ARG` once or many
-variables by specifying `ARG` more than once. For example, a valid Dockerfile:
-
-```
-FROM busybox
-ARG user1
-ARG buildno
-...
-```
-
-A Dockerfile author may optionally specify a default value for an `ARG` instruction:
-
-```
-FROM busybox
-ARG user1=someuser
-ARG buildno=1
-...
-```
-
-If an `ARG` value has a default and if there is no value passed at build-time, the
-builder uses the default.
-
-An `ARG` variable definition comes into effect from the line on which it is
-defined in the `Dockerfile` not from the argument's use on the command-line or
-elsewhere.  For example, consider this Dockerfile:
-
-```
-1 FROM busybox
-2 USER ${user:-some_user}
-3 ARG user
-4 USER $user
-...
-```
-A user builds this file by calling:
-
-```
-$ docker build --build-arg user=what_user .
-```
-
-The `USER` at line 2 evaluates to `some_user` as the `user` variable is defined on the
-subsequent line 3. The `USER` at line 4 evaluates to `what_user` as `user` is
-defined and the `what_user` value was passed on the command line. Prior to its definition by an
-`ARG` instruction, any use of a variable results in an empty string.
-
-> **Warning:** It is not recommended to use build-time variables for
->  passing secrets like github keys, user credentials etc. Build-time variable
->  values are visible to any user of the image with the `docker history` command.
-
-You can use an `ARG` or an `ENV` instruction to specify variables that are
-available to the `RUN` instruction. Environment variables defined using the
-`ENV` instruction always override an `ARG` instruction of the same name. Consider
-this Dockerfile with an `ENV` and `ARG` instruction.
-
-```
-1 FROM ubuntu
-2 ARG CONT_IMG_VER
-3 ENV CONT_IMG_VER v1.0.0
-4 RUN echo $CONT_IMG_VER
-```
-Then, assume this image is built with this command:
-
-```
-$ docker build --build-arg CONT_IMG_VER=v2.0.1 .
-```
-
-In this case, the `RUN` instruction uses `v1.0.0` instead of the `ARG` setting
-passed by the user:`v2.0.1` This behavior is similar to a shell
-script where a locally scoped variable overrides the variables passed as
-arguments or inherited from environment, from its point of definition.
-
-Using the example above but a different `ENV` specification you can create more
-useful interactions between `ARG` and `ENV` instructions:
-
-```
-1 FROM ubuntu
-2 ARG CONT_IMG_VER
-3 ENV CONT_IMG_VER ${CONT_IMG_VER:-v1.0.0}
-4 RUN echo $CONT_IMG_VER
-```
-
-Unlike an `ARG` instruction, `ENV` values are always persisted in the built
-image. Consider a docker build without the `--build-arg` flag:
-
-```
-$ docker build .
-```
-
-Using this Dockerfile example, `CONT_IMG_VER` is still persisted in the image but
-its value would be `v1.0.0` as it is the default set in line 3 by the `ENV` instruction.
-
-The variable expansion technique in this example allows you to pass arguments
-from the command line and persist them in the final image by leveraging the
-`ENV` instruction. Variable expansion is only supported for [a limited set of
-Dockerfile instructions.](#environment-replacement)
-
-Docker has a set of predefined `ARG` variables that you can use without a
-corresponding `ARG` instruction in the Dockerfile.
-
-* `HTTP_PROXY`
-* `http_proxy`
-* `HTTPS_PROXY`
-* `https_proxy`
-* `FTP_PROXY`
-* `ftp_proxy`
-* `NO_PROXY`
-* `no_proxy`
-
-To use these, simply pass them on the command line using the flag:
-
-```
---build-arg <varname>=<value>
-```
-
-By default, these pre-defined variables are excluded from the output of
-`docker history`. Excluding them reduces the risk of accidentally leaking
-sensitive authentication information in an `HTTP_PROXY` variable.
-
-For example, consider building the following Dockerfile using
-`--build-arg HTTP_PROXY=http://user:pass@proxy.lon.example.com`
-
-``` Dockerfile
-FROM ubuntu
-RUN echo "Hello World"
-```
-
-In this case, the value of the `HTTP_PROXY` variable is not available in the
-`docker history` and is not cached. If you were to change location, and your
-proxy server changed to `http://user:pass@proxy.sfo.example.com`, a subsequent
-build does not result in a cache miss.
-
-If you need to override this behaviour then you may do so by adding an `ARG`
-statement in the Dockerfile as follows:
-
-``` Dockerfile
-FROM ubuntu
-ARG HTTP_PROXY
-RUN echo "Hello World"
-```
-
-When building this Dockerfile, the `HTTP_PROXY` is preserved in the
-`docker history`, and changing its value invalidates the build cache.
-
-### Impact on build caching
-
-`ARG` variables are not persisted into the built image as `ENV` variables are.
-However, `ARG` variables do impact the build cache in similar ways. If a
-Dockerfile defines an `ARG` variable whose value is different from a previous
-build, then a "cache miss" occurs upon its first usage, not its definition. In
-particular, all `RUN` instructions following an `ARG` instruction use the `ARG`
-variable implicitly (as an environment variable), thus can cause a cache miss.
-All predefined `ARG` variables are exempt from caching unless there is a
-matching `ARG` statement in the `Dockerfile`.
-
-For example, consider these two Dockerfile:
-
-```
-1 FROM ubuntu
-2 ARG CONT_IMG_VER
-3 RUN echo $CONT_IMG_VER
-```
-
-```
-1 FROM ubuntu
-2 ARG CONT_IMG_VER
-3 RUN echo hello
-```
-
-If you specify `--build-arg CONT_IMG_VER=<value>` on the command line, in both
-cases, the specification on line 2 does not cause a cache miss; line 3 does
-cause a cache miss.`ARG CONT_IMG_VER` causes the RUN line to be identified
-as the same as running `CONT_IMG_VER=<value>` echo hello, so if the `<value>`
-changes, we get a cache miss.
-
-Consider another example under the same command line:
-
-```
-1 FROM ubuntu
-2 ARG CONT_IMG_VER
-3 ENV CONT_IMG_VER $CONT_IMG_VER
-4 RUN echo $CONT_IMG_VER
-```
-In this example, the cache miss occurs on line 3. The miss happens because
-the variable's value in the `ENV` references the `ARG` variable and that
-variable is changed through the command line. In this example, the `ENV`
-command causes the image to include the value.
-
-If an `ENV` instruction overrides an `ARG` instruction of the same name, like
-this Dockerfile:
-
-```
-1 FROM ubuntu
-2 ARG CONT_IMG_VER
-3 ENV CONT_IMG_VER hello
-4 RUN echo $CONT_IMG_VER
-```
-
-Line 3 does not cause a cache miss because the value of `CONT_IMG_VER` is a
-constant (`hello`). As a result, the environment variables and values used on
-the `RUN` (line 4) doesn't change between builds.
-
-## ONBUILD
-
-    ONBUILD [INSTRUCTION]
-
-The `ONBUILD` instruction adds to the image a *trigger* instruction to
-be executed at a later time, when the image is used as the base for
-another build. The trigger will be executed in the context of the
-downstream build, as if it had been inserted immediately after the
-`FROM` instruction in the downstream `Dockerfile`.
-
-Any build instruction can be registered as a trigger.
-
-This is useful if you are building an image which will be used as a base
-to build other images, for example an application build environment or a
-daemon which may be customized with user-specific configuration.
-
-For example, if your image is a reusable Python application builder, it
-will require application source code to be added in a particular
-directory, and it might require a build script to be called *after*
-that. You can't just call `ADD` and `RUN` now, because you don't yet
-have access to the application source code, and it will be different for
-each application build. You could simply provide application developers
-with a boilerplate `Dockerfile` to copy-paste into their application, but
-that is inefficient, error-prone and difficult to update because it
-mixes with application-specific code.
-
-The solution is to use `ONBUILD` to register advance instructions to
-run later, during the next build stage.
-
-Here's how it works:
-
-1. When it encounters an `ONBUILD` instruction, the builder adds a
-   trigger to the metadata of the image being built. The instruction
-   does not otherwise affect the current build.
-2. At the end of the build, a list of all triggers is stored in the
-   image manifest, under the key `OnBuild`. They can be inspected with
-   the `docker inspect` command.
-3. Later the image may be used as a base for a new build, using the
-   `FROM` instruction. As part of processing the `FROM` instruction,
-   the downstream builder looks for `ONBUILD` triggers, and executes
-   them in the same order they were registered. If any of the triggers
-   fail, the `FROM` instruction is aborted which in turn causes the
-   build to fail. If all triggers succeed, the `FROM` instruction
-   completes and the build continues as usual.
-4. Triggers are cleared from the final image after being executed. In
-   other words they are not inherited by "grand-children" builds.
-
-For example you might add something like this:
-
-    [...]
-    ONBUILD ADD . /app/src
-    ONBUILD RUN /usr/local/bin/python-build --dir /app/src
-    [...]
-
-> **Warning**: Chaining `ONBUILD` instructions using `ONBUILD ONBUILD` isn't allowed.
-
-> **Warning**: The `ONBUILD` instruction may not trigger `FROM` or `MAINTAINER` instructions.
-
-## STOPSIGNAL
-
-    STOPSIGNAL signal
-
-The `STOPSIGNAL` instruction sets the system call signal that will be sent to the container to exit.
-This signal can be a valid unsigned number that matches a position in the kernel's syscall table, for instance 9,
-or a signal name in the format SIGNAME, for instance SIGKILL.
-
-## HEALTHCHECK
-
-The `HEALTHCHECK` instruction has two forms:
-
-* `HEALTHCHECK [OPTIONS] CMD command` (check container health by running a command inside the container)
-* `HEALTHCHECK NONE` (disable any healthcheck inherited from the base image)
-
-The `HEALTHCHECK` instruction tells Docker how to test a container to check that
-it is still working. This can detect cases such as a web server that is stuck in
-an infinite loop and unable to handle new connections, even though the server
-process is still running.
-
-When a container has a healthcheck specified, it has a _health status_ in
-addition to its normal status. This status is initially `starting`. Whenever a
-health check passes, it becomes `healthy` (whatever state it was previously in).
-After a certain number of consecutive failures, it becomes `unhealthy`.
-
-The options that can appear before `CMD` are:
-
-* `--interval=DURATION` (default: `30s`)
-* `--timeout=DURATION` (default: `30s`)
-* `--start-period=DURATION` (default: `0s`)
-* `--retries=N` (default: `3`)
-
-The health check will first run **interval** seconds after the container is
-started, and then again **interval** seconds after each previous check completes.
-
-If a single run of the check takes longer than **timeout** seconds then the check
-is considered to have failed.
-
-It takes **retries** consecutive failures of the health check for the container
-to be considered `unhealthy`.
-
-**start period** provides initialization time for containers that need time to bootstrap.
-Probe failure during that period will not be counted towards the maximum number of retries.
-However, if a health check succeeds during the start period, the container is considered
-started and all consecutive failures will be counted towards the maximum number of retries.
-
-There can only be one `HEALTHCHECK` instruction in a Dockerfile. If you list
-more than one then only the last `HEALTHCHECK` will take effect.
-
-The command after the `CMD` keyword can be either a shell command (e.g. `HEALTHCHECK
-CMD /bin/check-running`) or an _exec_ array (as with other Dockerfile commands;
-see e.g. `ENTRYPOINT` for details).
-
-The command's exit status indicates the health status of the container.
-The possible values are:
-
-- 0: success - the container is healthy and ready for use
-- 1: unhealthy - the container is not working correctly
-- 2: reserved - do not use this exit code
-
-For example, to check every five minutes or so that a web-server is able to
-serve the site's main page within three seconds:
-
-    HEALTHCHECK --interval=5m --timeout=3s \
-      CMD curl -f http://localhost/ || exit 1
-
-To help debug failing probes, any output text (UTF-8 encoded) that the command writes
-on stdout or stderr will be stored in the health status and can be queried with
-`docker inspect`. Such output should be kept short (only the first 4096 bytes
-are stored currently).
-
-When the health status of a container changes, a `health_status` event is
-generated with the new status.
-
-The `HEALTHCHECK` feature was added in Docker 1.12.
-
-
-## SHELL
-
-    SHELL ["executable", "parameters"]
-
-The `SHELL` instruction allows the default shell used for the *shell* form of
-commands to be overridden. The default shell on Linux is `["/bin/sh", "-c"]`, and on
-Windows is `["cmd", "/S", "/C"]`. The `SHELL` instruction *must* be written in JSON
-form in a Dockerfile.
-
-The `SHELL` instruction is particularly useful on Windows where there are
-two commonly used and quite different native shells: `cmd` and `powershell`, as
-well as alternate shells available including `sh`.
-
-The `SHELL` instruction can appear multiple times. Each `SHELL` instruction overrides
-all previous `SHELL` instructions, and affects all subsequent instructions. For example:
-
-    FROM microsoft/windowsservercore
-
-    # Executed as cmd /S /C echo default
-    RUN echo default
-
-    # Executed as cmd /S /C powershell -command Write-Host default
-    RUN powershell -command Write-Host default
-
-    # Executed as powershell -command Write-Host hello
-    SHELL ["powershell", "-command"]
-    RUN Write-Host hello
-
-    # Executed as cmd /S /C echo hello
-    SHELL ["cmd", "/S"", "/C"]
-    RUN echo hello
-
-The following instructions can be affected by the `SHELL` instruction when the
-*shell* form of them is used in a Dockerfile: `RUN`, `CMD` and `ENTRYPOINT`.
-
-The following example is a common pattern found on Windows which can be
-streamlined by using the `SHELL` instruction:
-
-    ...
-    RUN powershell -command Execute-MyCmdlet -param1 "c:\foo.txt"
-    ...
-
-The command invoked by docker will be:
-
-    cmd /S /C powershell -command Execute-MyCmdlet -param1 "c:\foo.txt"
-
-This is inefficient for two reasons. First, there is an un-necessary cmd.exe command
-processor (aka shell) being invoked. Second, each `RUN` instruction in the *shell*
-form requires an extra `powershell -command` prefixing the command.
-
-To make this more efficient, one of two mechanisms can be employed. One is to
-use the JSON form of the RUN command such as:
-
-    ...
-    RUN ["powershell", "-command", "Execute-MyCmdlet", "-param1 \"c:\\foo.txt\""]
-    ...
-
-While the JSON form is unambiguous and does not use the un-necessary cmd.exe,
-it does require more verbosity through double-quoting and escaping. The alternate
-mechanism is to use the `SHELL` instruction and the *shell* form,
-making a more natural syntax for Windows users, especially when combined with
-the `escape` parser directive:
-
-    # escape=`
-
-    FROM microsoft/nanoserver
-    SHELL ["powershell","-command"]
-    RUN New-Item -ItemType Directory C:\Example
-    ADD Execute-MyCmdlet.ps1 c:\example\
-    RUN c:\example\Execute-MyCmdlet -sample 'hello world'
-
-Resulting in:
-
-    PS E:\docker\build\shell> docker build -t shell .

-The `SHELL` instruction could also be used to modify the way in which
-a shell operates. For example, using `SHELL cmd /S /C /V:ON|OFF` on Windows, delayed
-environment variable expansion semantics could be modified.
-
-The `SHELL` instruction can also be used on Linux should an alternate shell be
-required such as `zsh`, `csh`, `tcsh` and others.
-
-The `SHELL` feature was added in Docker 1.12.

-# attach
-
-```markdown
-Usage: docker attach [OPTIONS] CONTAINER
-
-Attach local standard input, output, and error streams to a running container
-
-Options:
-      --detach-keys string   Override the key sequence for detaching a container
-      --help                 Print usage
-      --no-stdin             Do not attach STDIN
-      --sig-proxy            Proxy all received signals to the process (default true)
-```
-
-## Description
-
-Use `docker attach` to attach your terminal's standard input, output, and error
-(or any combination of the three) to a running container using the container's
-ID or name. This allows you to view its ongoing output or to control it
-interactively, as though the commands were running directly in your terminal.
-
-> **Note:**
-> The `attach` command will display the output of the `ENTRYPOINT/CMD` process.  This
-> can appear as if the attach command is hung when in fact the process may simply
-> not be interacting with the terminal at that time.
-
-You can attach to the same contained process multiple times simultaneously,
-even as a different user with the appropriate permissions.
-
-To stop a container, use `CTRL-c`. This key sequence sends `SIGKILL` to the
-container. If `--sig-proxy` is true (the default),`CTRL-c` sends a `SIGINT` to
-the container. You can detach from a container and leave it running using the
- `CTRL-p CTRL-q` key sequence.
-
-> **Note:**
-> A process running as PID 1 inside a container is treated specially by
-> Linux: it ignores any signal with the default action. So, the process
-> will not terminate on `SIGINT` or `SIGTERM` unless it is coded to do
-> so.
-
-It is forbidden to redirect the standard input of a `docker attach` command
-while attaching to a tty-enabled container (i.e.: launched with `-t`).
-
-While a client is connected to container's stdio using `docker attach`, Docker
-uses a ~1MB memory buffer to maximize the throughput of the application. If
-this buffer is filled, the speed of the API connection will start to have an
-effect on the process output writing speed. This is similar to other
-applications like SSH. Because of this, it is not recommended to run
-performance critical applications that generate a lot of output in the
-foreground over a slow client connection. Instead, users should use the
-`docker logs` command to get access to the logs.
-
-### Override the detach sequence
-
-If you want, you can configure an override the Docker key sequence for detach.
-This is useful if the Docker default sequence conflicts with key sequence you
-use for other applications. There are two ways to define your own detach key
-sequence, as a per-container override or as a configuration property on  your
-entire configuration.
-
-To override the sequence for an individual container, use the
-`--detach-keys="<sequence>"` flag with the `docker attach` command. The format of
-the `<sequence>` is either a letter [a-Z], or the `ctrl-` combined with any of
-the following:
-
-* `a-z` (a single lowercase alpha character )
-* `@` (at sign)
-* `[` (left bracket)
-* `\\` (two backward slashes)
-*  `_` (underscore)
-* `^` (caret)
-
-These `a`, `ctrl-a`, `X`, or `ctrl-\\` values are all examples of valid key
-sequences. To configure a different configuration default key sequence for all
-containers, see [**Configuration file** section](cli.md#configuration-files).

-
-## Description
-
-Builds Docker images from a Dockerfile and a "context". A build's context is
-the files located in the specified `PATH` or `URL`. The build process can refer
-to any of the files in the context. For example, your build can use an
-[*ADD*](../builder.md#add) instruction to reference a file in the
-context.
-
-The `URL` parameter can refer to three kinds of resources: Git repositories,
-pre-packaged tarball contexts and plain text files.
-
-### Git repositories
-
-When the `URL` parameter points to the location of a Git repository, the
-repository acts as the build context. The system recursively fetches the
-repository and its submodules. The commit history is not preserved. A
-repository is first pulled into a temporary directory on your local host. After
-the that succeeds, the directory is sent to the Docker daemon as the context.
-Local copy gives you the ability to access private repositories using local
-user credentials, VPN's, and so forth.
-
-> **Note:**
-> If the `URL` parameter contains a fragment the system will recursively clone
-> the repository and its submodules using a `git clone --recursive` command.
-
-Git URLs accept context configuration in their fragment section, separated by a
-colon `:`.  The first part represents the reference that Git will check out,
-this can be either a branch, a tag, or a remote reference. The second part
-represents a subdirectory inside the repository that will be used as a build
-context.
-
-For example, run this command to use a directory called `docker` in the branch
-`container`:
-
-```bash
-$ docker build https://github.com/docker/rootfs.git#container:docker
-```
-
-The following table represents all the valid suffixes with their build
-contexts:
-
-Build Syntax Suffix             | Commit Used           | Build Context Used
---------------------------------|-----------------------|-------------------
-`myrepo.git`                    | `refs/heads/master`   | `/`
-`myrepo.git#mytag`              | `refs/tags/mytag`     | `/`
-`myrepo.git#mybranch`           | `refs/heads/mybranch` | `/`
-`myrepo.git#pull/42/head`       | `refs/pull/42/head`   | `/`
-`myrepo.git#:myfolder`          | `refs/heads/master`   | `/myfolder`
-`myrepo.git#master:myfolder`    | `refs/heads/master`   | `/myfolder`
-`myrepo.git#mytag:myfolder`     | `refs/tags/mytag`     | `/myfolder`
-`myrepo.git#mybranch:myfolder`  | `refs/heads/mybranch` | `/myfolder`
-
-
-### Tarball contexts
-
-If you pass an URL to a remote tarball, the URL itself is sent to the daemon:
-
-```bash
-$ docker build http://server/context.tar.gz
-```
-
-The download operation will be performed on the host the Docker daemon is
-running on, which is not necessarily the same host from which the build command
-is being issued. The Docker daemon will fetch `context.tar.gz` and use it as the
-build context. Tarball contexts must be tar archives conforming to the standard
-`tar` UNIX format and can be compressed with any one of the 'xz', 'bzip2',
-'gzip' or 'identity' (no compression) formats.
-
-### Text files
-
-Instead of specifying a context, you can pass a single `Dockerfile` in the
-`URL` or pipe the file in via `STDIN`. To pipe a `Dockerfile` from `STDIN`:
-
-```bash
-$ docker build - < Dockerfile
-```
-
-With Powershell on Windows, you can run:
-
-```powershell
-Get-Content Dockerfile | docker build -
-```
-
-If you use `STDIN` or specify a `URL` pointing to a plain text file, the system
-places the contents into a file called `Dockerfile`, and any `-f`, `--file`
-option is ignored. In this scenario, there is no context.
-
-By default the `docker build` command will look for a `Dockerfile` at the root
-of the build context. The `-f`, `--file`, option lets you specify the path to
-an alternative file to use instead. This is useful in cases where the same set
-of files are used for multiple builds. The path must be to a file within the
-build context. If a relative path is specified then it is interpreted as
-relative to the root of the context.
-
-In most cases, it's best to put each Dockerfile in an empty directory. Then,
-add to that directory only the files needed for building the Dockerfile. To
-increase the build's performance, you can exclude files and directories by
-adding a `.dockerignore` file to that directory as well. For information on
-creating one, see the [.dockerignore file](../builder.md#dockerignore-file).
-
-If the Docker client loses connection to the daemon, the build is canceled.
-This happens if you interrupt the Docker client with `CTRL-c` or if the Docker
-client is killed for any reason. If the build initiated a pull which is still
-running at the time the build is cancelled, the pull is cancelled as well.
-
-## Return code
-
-On a successful build, a return code of success `0` will be returned.  When the
-build fails, a non-zero failure code will be returned.
-
-There should be informational output of the reason for failure output to
-`STDERR`:
-
-```bash
-$ docker build -t fail .
-
-Sending build context to Docker daemon 2.048 kB
-Sending build context to Docker daemon

-
-This example specifies that the `PATH` is `.`, and so all the files in the
-local directory get `tar`d and sent to the Docker daemon. The `PATH` specifies
-where to find the files for the "context" of the build on the Docker daemon.
-Remember that the daemon could be running on a remote machine and that no
-parsing of the Dockerfile happens at the client side (where you're running
-`docker build`). That means that *all* the files at `PATH` get sent, not just
-the ones listed to [*ADD*](../builder.md#add) in the Dockerfile.
-
-The transfer of context from the local machine to the Docker daemon is what the
-`docker` client means when you see the "Sending build context" message.
-
-If you wish to keep the intermediate containers after the build is complete,
-you must use `--rm=false`. This does not affect the build cache.
-
-### Build with URL
-
-```bash
-$ docker build github.com/creack/docker-firefox
-```
-
-This will clone the GitHub repository and use the cloned repository as context.
-The Dockerfile at the root of the repository is used as Dockerfile. You can
-specify an arbitrary Git repository by using the `git://` or `git@` scheme.
-
-```bash
-$ docker build -f ctx/Dockerfile http://server/ctx.tar.gz

-
-This sends the URL `http://server/ctx.tar.gz` to the Docker daemon, which
-downloads and extracts the referenced tarball. The `-f ctx/Dockerfile`
-parameter specifies a path inside `ctx.tar.gz` to the `Dockerfile` that is used
-to build the image. Any `ADD` commands in that `Dockerfile` that refers to local
-paths must be relative to the root of the contents inside `ctx.tar.gz`. In the
-example above, the tarball contains a directory `ctx/`, so the `ADD
-ctx/container.cfg /` operation works as expected.
-
-### Build with -
-
-```bash
-$ docker build - < Dockerfile
-```
-
-This will read a Dockerfile from `STDIN` without context. Due to the lack of a
-context, no contents of any local directory will be sent to the Docker daemon.
-Since there is no context, a Dockerfile `ADD` only works if it refers to a
-remote URL.
-
-```bash
-$ docker build - < context.tar.gz
-```
-
-This will build an image for a compressed context read from `STDIN`.  Supported
-formats are: bzip2, gzip and xz.
-
-### Use a .dockerignore file
-
-```bash
-$ docker build .
-

-Uploading context

-Successfully built 99cc1ad10469
-```
-
-This example shows the use of the `.dockerignore` file to exclude the `.git`
-directory from the context. Its effect can be seen in the changed size of the
-uploaded context. The builder reference contains detailed information on
-[creating a .dockerignore file](../builder.md#dockerignore-file)
-
-### Tag an image (-t)
-
-```bash
-$ docker build -t vieux/apache:2.0 .
-```
-
-This will build like the previous example, but it will then tag the resulting
-image. The repository name will be `vieux/apache` and the tag will be `2.0`.
-[Read more about valid tags](tag.md).
-
-You can apply multiple tags to an image. For example, you can apply the `latest`
-tag to a newly built image and add another tag that references a specific
-version.
-For example, to tag an image both as `whenry/fedora-jboss:latest` and
-`whenry/fedora-jboss:v2.1`, use the following:
-
-```bash
-$ docker build -t whenry/fedora-jboss:latest -t whenry/fedora-jboss:v2.1 .
-```
-
-### Specify a Dockerfile (-f)
-
-```bash
-$ docker build -f Dockerfile.debug .
-```
-
-This will use a file called `Dockerfile.debug` for the build instructions
-instead of `Dockerfile`.
-
-```bash
-$ curl example.com/remote/Dockerfile | docker build -f - .
-```
-
-The above command will use the current directory as the build context and read
-a Dockerfile from stdin.
-
-```bash
-$ docker build -f dockerfiles/Dockerfile.debug -t myapp_debug .
-$ docker build -f dockerfiles/Dockerfile.prod  -t myapp_prod .
-```
-
-The above commands will build the current build context (as specified by the
-`.`) twice, once using a debug version of a `Dockerfile` and once using a
-production version.
-
-```bash
-$ cd /home/me/myapp/some/dir/really/deep
-$ docker build -f /home/me/myapp/dockerfiles/debug /home/me/myapp
-$ docker build -f ../../../../dockerfiles/debug /home/me/myapp
-```
-
-These two `docker build` commands do the exact same thing. They both use the
-contents of the `debug` file instead of looking for a `Dockerfile` and will use
-`/home/me/myapp` as the root of the build context. Note that `debug` is in the
-directory structure of the build context, regardless of how you refer to it on
-the command line.
-
-> **Note:**
-> `docker build` will return a `no such file or directory` error if the
-> file or directory does not exist in the uploaded context. This may
-> happen if there is no context, or if you specify a file that is
-> elsewhere on the Host system. The context is limited to the current
-> directory (and its children) for security reasons, and to ensure
-> repeatable builds on remote Docker hosts. This is also the reason why
-> `ADD ../file` will not work.
-
-### Use a custom parent cgroup (--cgroup-parent)
-
-When `docker build` is run with the `--cgroup-parent` option the containers
-used in the build will be run with the [corresponding `docker run`
-flag](../run.md#specifying-custom-cgroups).
-
-### Set ulimits in container (--ulimit)
-
-Using the `--ulimit` option with `docker build` will cause each build step's
-container to be started using those [`--ulimit`
-flag values](./run.md#set-ulimits-in-container-ulimit).
-
-### Set build-time variables (--build-arg)
-
-You can use `ENV` instructions in a Dockerfile to define variable
-values. These values persist in the built image. However, often
-persistence is not what you want. Users want to specify variables differently
-depending on which host they build an image on.
-
-A good example is `http_proxy` or source versions for pulling intermediate
-files. The `ARG` instruction lets Dockerfile authors define values that users
-can set at build-time using the  `--build-arg` flag:
-
-```bash
-$ docker build --build-arg HTTP_PROXY=http://10.20.30.2:1234 .
-```
-
-This flag allows you to pass the build-time variables that are
-accessed like regular environment variables in the `RUN` instruction of the
-Dockerfile. Also, these values don't persist in the intermediate or final images
-like `ENV` values do.
-
-Using this flag will not alter the output you see when the `ARG` lines from the
-Dockerfile are echoed during the build process.
-
-For detailed information on using `ARG` and `ENV` instructions, see the
-[Dockerfile reference](../builder.md).
-
-### Optional security options (--security-opt)
-
-This flag is only supported on a daemon running on Windows, and only supports
-the `credentialspec` option. The `credentialspec` must be in the format
-`file://spec.txt` or `registry://keyname`.
-
-### Specify isolation technology for container (--isolation)
-
-This option is useful in situations where you are running Docker containers on
-Windows. The `--isolation=<value>` option sets a container's isolation
-technology. On Linux, the only supported is the `default` option which uses
-Linux namespaces. On Microsoft Windows, you can specify these values:
-
-
-| Value     | Description                                                                                                                                                   |
-|-----------|---------------------------------------------------------------------------------------------------------------------------------------------------------------|
-| `default` | Use the value specified by the Docker daemon's `--exec-opt` . If the `daemon` does not specify an isolation technology, Microsoft Windows uses `process` as its default value.  |
-| `process` | Namespace isolation only.                                                                                                                                     |
-| `hyperv`  | Hyper-V hypervisor partition-based isolation.                                                                                                                 |
-
-Specifying the `--isolation` flag without a value is the same as setting `--isolation="default"`.
-
-### Add entries to container hosts file (--add-host)
-
-You can add other hosts into a container's `/etc/hosts` file by using one or
-more `--add-host` flags. This example adds a static address for a host named
-`docker`:
-
-    $ docker build --add-host=docker:10.180.0.1 .
-
-### Specifying target build stage (--target)
-
-When building a Dockerfile with multiple build stages, `--target` can be used to
-specify an intermediate build stage by name as a final stage for the resulting
-image. Commands after the target stage will be skipped.
-
-```Dockerfile
-FROM debian AS build-env
-...
-
-FROM alpine AS production-env
-...
-```
-
-```bash
-$ docker build -t mybuildimage --target build-env .
-```
-
-### Squash an image's layers (--squash) **Experimental Only**
-
-#### Overview
-
-Once the image is built, squash the new layers into a new image with a single
-new layer. Squashing does not destroy any existing image, rather it creates a new
-image with the content of the squashed layers. This effectively makes it look
-like all `Dockerfile` commands were created with a single layer. The build
-cache is preserved with this method.
-
-**Note**: using this option means the new image will not be able to take
-advantage of layer sharing with other images and may use significantly more
-space.
-
-**Note**: using this option you may see significantly more space used due to
-storing two copies of the image, one for the build cache with all the cache
-layers in tact, and one for the squashed version.
-
-#### Prerequisites
-
-The example on this page is using experimental mode in Docker 1.13.
-
-Experimental mode can be enabled by using the `--experimental` flag when starting the Docker daemon or setting `experimental: true` in the `daemon.json` configuration file.
-
-By default, experimental mode is disabled. To see the current configuration, use the `docker version` command.
-
-```none
-
-Server:
- Version:      1.13.1
- API version:  1.26 (minimum version 1.12)
- Go version:   go1.7.5
- Git commit:   092cba3
- Built:        Wed Feb  8 06:35:24 2017
- OS/Arch:      linux/amd64
- Experimental: false
-
- [...]
-
-```
-
-To enable experimental mode, users need to restart the docker daemon with the experimental flag enabled.
-
-#### Enable Docker experimental
-
-Experimental features are now included in the standard Docker binaries as of version 1.13.0. For enabling experimental features, you need to start the Docker daemon with `--experimental` flag. You can also enable the daemon flag via /etc/docker/daemon.json. e.g.
-
-```
-
-{
-    "experimental": true
-}
-
-```
-Then make sure the experimental flag is enabled:
-
-```bash
-
-$ docker version -f '{{.Server.Experimental}}'
-true
-
-```
-
-#### Build an image with `--squash` argument
-
-The following is an example of docker build with `--squash` argument
-
-```Dockerfile
-
-FROM busybox
-RUN echo hello > /hello
-RUN echo world >> /hello
-RUN touch remove_me /remove_me
-ENV HELLO world
-RUN rm /remove_me
-
-```
-An image named `test` is built with `--squash` argument.
-
-```bash
-
-$ docker build --squash -t test .
-
-[...]
-
-```
-
-If everything is right, the history will look like this:
-
-```bash
-$ docker history test 
-
-IMAGE               CREATED             CREATED BY                                      SIZE                COMMENT
-4e10cb5b4cac        3 seconds ago                                                       12 B                merge sha256:88a7b0112a41826885df0e7072698006ee8f621c6ab99fca7fe9151d7b599702 to sha256:47bcc53f74dc94b1920f0b34f6036096526296767650f223433fe65c35f149eb
-<missing>           5 minutes ago       /bin/sh -c rm /remove_me                        0 B
-<missing>           5 minutes ago       /bin/sh -c #(nop) ENV HELLO=world               0 B
-<missing>           5 minutes ago       /bin/sh -c touch remove_me /remove_me           0 B
-<missing>           5 minutes ago       /bin/sh -c echo world >> /hello                 0 B
-<missing>           6 minutes ago       /bin/sh -c echo hello > /hello                  0 B
-<missing>           7 weeks ago         /bin/sh -c #(nop) CMD ["sh"]                    0 B
-<missing>           7 weeks ago         /bin/sh -c #(nop) ADD file:47ca6e777c36a4cfff   1.113 MB
-
-```
-We could find that all layer's name is `<missing>`, and there is a new layer with COMMENT `merge`.
-
-Test the image, check for `/remove_me` being gone, make sure `hello\nworld` is in `/hello`, make sure the `HELLO` envvar's value is `world`.

-
-## Description
-
-Depending on your Docker system configuration, you may be required to preface
-each `docker` command with `sudo`. To avoid having to use `sudo` with the
-`docker` command, your system administrator can create a Unix group called
-`docker` and add users to it.
-
-For more information about installing Docker or `sudo` configuration, refer to
-the [installation](https://docs.docker.com/engine/installation/) instructions for your operating system.
-
-### Environment variables
-
-For easy reference, the following list of environment variables are supported
-by the `docker` command line:
-
-* `DOCKER_API_VERSION` The API version to use (e.g. `1.19`)
-* `DOCKER_CONFIG` The location of your client configuration files.
-* `DOCKER_CERT_PATH` The location of your authentication keys.
-* `DOCKER_DRIVER` The graph driver to use.
-* `DOCKER_HOST` Daemon socket to connect to.
-* `DOCKER_NOWARN_KERNEL_VERSION` Prevent warnings that your Linux kernel is
-  unsuitable for Docker.
-* `DOCKER_RAMDISK` If set this will disable 'pivot_root'.
-* `DOCKER_TLS_VERIFY` When set Docker uses TLS and verifies the remote.
-* `DOCKER_CONTENT_TRUST` When set Docker uses notary to sign and verify images.
-  Equates to `--disable-content-trust=false` for build, create, pull, push, run.
-* `DOCKER_CONTENT_TRUST_SERVER` The URL of the Notary server to use. This defaults
-  to the same URL as the registry.
-* `DOCKER_HIDE_LEGACY_COMMANDS` When set, Docker hides "legacy" top-level commands (such as `docker rm`, and
-  `docker pull`) in `docker help` output, and only `Management commands` per object-type (e.g., `docker container`) are
-  printed. This may become the default in a future release, at which point this environment-variable is removed.
-* `DOCKER_TMPDIR` Location for temporary Docker files.
-
-Because Docker is developed using Go, you can also use any environment
-variables used by the Go runtime. In particular, you may find these useful:
-
-* `HTTP_PROXY`
-* `HTTPS_PROXY`
-* `NO_PROXY`
-
-These Go environment variables are case-insensitive. See the
-[Go specification](http://golang.org/pkg/net/http/) for details on these
-variables.
-
-### Configuration files
-
-By default, the Docker command line stores its configuration files in a
-directory called `.docker` within your `$HOME` directory. However, you can
-specify a different location via the `DOCKER_CONFIG` environment variable
-or the `--config` command line option. If both are specified, then the
-`--config` option overrides the `DOCKER_CONFIG` environment variable.
-For example:
-
-    docker --config ~/testconfigs/ ps
-
-Instructs Docker to use the configuration files in your `~/testconfigs/`
-directory when running the `ps` command.
-
-Docker manages most of the files in the configuration directory
-and you should not modify them. However, you *can modify* the
-`config.json` file to control certain aspects of how the `docker`
-command behaves.
-
-Currently, you can modify the `docker` command behavior using environment
-variables or command-line options. You can also use options within
-`config.json` to modify some of the same behavior. When using these
-mechanisms, you must keep in mind the order of precedence among them. Command
-line options override environment variables and environment variables override
-properties you specify in a `config.json` file.
-
-The `config.json` file stores a JSON encoding of several properties:
-
-The property `HttpHeaders` specifies a set of headers to include in all messages
-sent from the Docker client to the daemon. Docker does not try to interpret or
-understand these header; it simply puts them into the messages. Docker does
-not allow these headers to change any headers it sets for itself.
-
-The property `psFormat` specifies the default format for `docker ps` output.
-When the `--format` flag is not provided with the `docker ps` command,
-Docker's client uses this property. If this property is not set, the client
-falls back to the default table format. For a list of supported formatting
-directives, see the
-[**Formatting** section in the `docker ps` documentation](ps.md)
-
-The property `imagesFormat` specifies the default format for `docker images` output.
-When the `--format` flag is not provided with the `docker images` command,
-Docker's client uses this property. If this property is not set, the client
-falls back to the default table format. For a list of supported formatting
-directives, see the [**Formatting** section in the `docker images` documentation](images.md)
-
-The property `pluginsFormat` specifies the default format for `docker plugin ls` output.
-When the `--format` flag is not provided with the `docker plugin ls` command,
-Docker's client uses this property. If this property is not set, the client
-falls back to the default table format. For a list of supported formatting
-directives, see the [**Formatting** section in the `docker plugin ls` documentation](plugin_ls.md)
-
-The property `servicesFormat` specifies the default format for `docker
-service ls` output. When the `--format` flag is not provided with the
-`docker service ls` command, Docker's client uses this property. If this
-property is not set, the client falls back to the default json format. For a
-list of supported formatting directives, see the
-[**Formatting** section in the `docker service ls` documentation](service_ls.md)
-
-The property `serviceInspectFormat` specifies the default format for `docker
-service inspect` output. When the `--format` flag is not provided with the
-`docker service inspect` command, Docker's client uses this property. If this
-property is not set, the client falls back to the default json format. For a
-list of supported formatting directives, see the
-[**Formatting** section in the `docker service inspect` documentation](service_inspect.md)
-
-The property `statsFormat` specifies the default format for `docker
-stats` output. When the `--format` flag is not provided with the
-`docker stats` command, Docker's client uses this property. If this
-property is not set, the client falls back to the default table
-format. For a list of supported formatting directives, see
-[**Formatting** section in the `docker stats` documentation](stats.md)
-
-The property `secretFormat` specifies the default format for `docker
-secret ls` output. When the `--format` flag is not provided with the
-`docker secret ls` command, Docker's client uses this property. If this
-property is not set, the client falls back to the default table
-format. For a list of supported formatting directives, see
-[**Formatting** section in the `docker secret ls` documentation](secret_ls.md)
-
-
-The property `nodesFormat` specifies the default format for `docker node ls` output.
-When the `--format` flag is not provided with the `docker node ls` command,
-Docker's client uses the value of `nodesFormat`. If the value of `nodesFormat` is not set,
-the client uses the default table format. For a list of supported formatting
-directives, see the [**Formatting** section in the `docker node ls` documentation](node_ls.md)
-
-The property `configFormat` specifies the default format for `docker
-config ls` output. When the `--format` flag is not provided with the
-`docker config ls` command, Docker's client uses this property. If this
-property is not set, the client falls back to the default table
-format. For a list of supported formatting directives, see
-[**Formatting** section in the `docker config ls` documentation](config_ls.md)
-
-The property `credsStore` specifies an external binary to serve as the default
-credential store. When this property is set, `docker login` will attempt to
-store credentials in the binary specified by `docker-credential-<value>` which
-is visible on `$PATH`. If this property is not set, credentials will be stored
-in the `auths` property of the config. For more information, see the
-[**Credentials store** section in the `docker login` documentation](login.md#credentials-store)
-
-The property `credHelpers` specifies a set of credential helpers to use
-preferentially over `credsStore` or `auths` when storing and retrieving
-credentials for specific registries. If this property is set, the binary
-`docker-credential-<value>` will be used when storing or retrieving credentials
-for a specific registry. For more information, see the
-[**Credential helpers** section in the `docker login` documentation](login.md#credential-helpers)
-
-Once attached to a container, users detach from it and leave it running using
-the using `CTRL-p CTRL-q` key sequence. This detach key sequence is customizable
-using the `detachKeys` property. Specify a `<sequence>` value for the
-property. The format of the `<sequence>` is a comma-separated list of either
-a letter [a-Z], or the `ctrl-` combined with any of the following:
-
-* `a-z` (a single lowercase alpha character )
-* `@` (at sign)
-* `[` (left bracket)
-* `\\` (two backward slashes)
-*  `_` (underscore)
-* `^` (caret)
-
-Your customization applies to all containers started in with your Docker client.
-Users can override your custom or the default key sequence on a per-container
-basis. To do this, the user specifies the `--detach-keys` flag with the `docker
-attach`, `docker exec`, `docker run` or `docker start` command.
-
-Following is a sample `config.json` file:
-
-```json
-{
-  "HttpHeaders": {
-    "MyHeader": "MyValue"
-  },
-  "psFormat": "table {{.ID}}\\t{{.Image}}\\t{{.Command}}\\t{{.Labels}}",
-  "imagesFormat": "table {{.ID}}\\t{{.Repository}}\\t{{.Tag}}\\t{{.CreatedAt}}",

-### Notary
-
-If using your own notary server and a self-signed certificate or an internal
-Certificate Authority, you need to place the certificate at
-`tls/<registry_url>/ca.crt` in your docker config directory.
-
-Alternatively you can trust the certificate globally by adding it to your system's
-list of root Certificate Authorities.
-
-## Examples
-
-### Display help text
-
-To list the help on any command just execute the command, followed by the
-`--help` option.
-
-    $ docker run --help
-
-    Usage: docker run [OPTIONS] IMAGE [COMMAND] [ARG...]
-
-    Run a command in a new container
-
-    Options:
-          --add-host value             Add a custom host-to-IP mapping (host:ip) (default [])
-      -a, --attach value               Attach to STDIN, STDOUT or STDERR (default [])
-    ...
-
-### Option types
-
-Single character command line options can be combined, so rather than
-typing `docker run -i -t --name test busybox sh`,
-you can write `docker run -it --name test busybox sh`.
-
-#### Boolean
-
-Boolean options take the form `-d=false`. The value you see in the help text is
-the default value which is set if you do **not** specify that flag. If you
-specify a Boolean flag without a value, this will set the flag to `true`,
-irrespective of the default value.
-
-For example, running `docker run -d` will set the value to `true`, so your
-container **will** run in "detached" mode, in the background.
-
-Options which default to `true` (e.g., `docker build --rm=true`) can only be
-set to the non-default value by explicitly setting them to `false`:
-
-```bash
-$ docker build --rm=false .
-```
-
-#### Multi
-
-You can specify options like `-a=[]` multiple times in a single command line,
-for example in these commands:
-
-```bash
-$ docker run -a stdin -a stdout -i -t ubuntu /bin/bash
-
-$ docker run -a stdin -a stdout -a stderr ubuntu /bin/ls
-```
-
-Sometimes, multiple options can call for a more complex value string as for
-`-v`:
-
-```bash
-$ docker run -v /host:/container example/mysql
-```
-
-> **Note**: Do not use the `-t` and `-a stderr` options together due to
-> limitations in the `pty` implementation. All `stderr` in `pty` mode
-> simply goes to `stdout`.
-
-#### Strings and Integers
-
-Options like `--name=""` expect a string, and they
-can only be specified once. Options like `-c=0`
-expect an integer, and they can only be specified once.

-# commit
-
-```markdown
-Usage:  docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]
-
-Create a new image from a container's changes
-
-Options:
-  -a, --author string    Author (e.g., "John Hannibal Smith <hannibal@a-team.com>")
-  -c, --change value     Apply Dockerfile instruction to the created image (default [])
-      --help             Print usage
-  -m, --message string   Commit message
-  -p, --pause            Pause container during commit (default true)
-```
-
-## Description
-
-It can be useful to commit a container's file changes or settings into a new
-image. This allows you to debug a container by running an interactive shell, or to
-export a working dataset to another server. Generally, it is better to use
-Dockerfiles to manage your images in a documented and maintainable way.
-[Read more about valid image names and tags](tag.md).
-
-The commit operation will not include any data contained in
-volumes mounted inside the container.
-
-By default, the container being committed and its processes will be paused
-while the image is committed. This reduces the likelihood of encountering data
-corruption during the process of creating the commit.  If this behavior is
-undesired, set the `--pause` option to false.
-
-The `--change` option will apply `Dockerfile` instructions to the image that is
-created.  Supported `Dockerfile` instructions:
-`CMD`|`ENTRYPOINT`|`ENV`|`EXPOSE`|`LABEL`|`ONBUILD`|`USER`|`VOLUME`|`WORKDIR`

-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
-than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
-
-The currently supported filters are:
-
-* until (`<timestamp>`) - only remove containers created before given timestamp
-* label (`label=<key>`, `label=<key>=<value>`, `label!=<key>`, or `label!=<key>=<value>`) - only remove containers with (or without, in case `label!=...` is used) the specified labels.
-
-The `until` filter can be Unix timestamps, date formatted
-timestamps, or Go duration strings (e.g. `10m`, `1h30m`) computed
-relative to the daemon machine’s time. Supported formats for date
-formatted time stamps include RFC3339Nano, RFC3339, `2006-01-02T15:04:05`,
-`2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
-timezone on the daemon will be used if you do not provide either a `Z` or a
-`+-00:00` timezone offset at the end of the timestamp.  When providing Unix
-timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
-that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
-seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
-fraction of a second no more than nine digits long.
-
-The `label` filter accepts two formats. One is the `label=...` (`label=<key>` or `label=<key>=<value>`),
-which removes containers with the specified labels. The other
-format is the `label!=...` (`label!=<key>` or `label!=<key>=<value>`), which removes
-containers without the specified labels.
-
-The following removes containers created more than 5 minutes ago:
-
-```bash
-$ docker ps -a --format 'table {{.ID}}\t{{.Image}}\t{{.Command}}\t{{.CreatedAt}}\t{{.Status}}'

-# cp
-
-```markdown
-Usage:  docker cp [OPTIONS] CONTAINER:SRC_PATH DEST_PATH|-
-        docker cp [OPTIONS] SRC_PATH|- CONTAINER:DEST_PATH
-
-Copy files/folders between a container and the local filesystem
-
-Use '-' as the source to read a tar archive from stdin
-and extract it to a directory destination in a container.
-Use '-' as the destination to stream a tar archive of a
-container source to stdout.
-
-Options:
-  -L, --follow-link   Always follow symbol link in SRC_PATH
-      --help          Print usage
-```
-
-## Description
-
-The `docker cp` utility copies the contents of `SRC_PATH` to the `DEST_PATH`.
-You can copy from the container's file system to the local machine or the
-reverse, from the local filesystem to the container. If `-` is specified for
-either the `SRC_PATH` or `DEST_PATH`, you can also stream a tar archive from
-`STDIN` or to `STDOUT`. The `CONTAINER` can be a running or stopped container.
-The `SRC_PATH` or `DEST_PATH` can be a file or directory.
-
-The `docker cp` command assumes container paths are relative to the container's
-`/` (root) directory. This means supplying the initial forward slash is optional;
-The command sees `compassionate_darwin:/tmp/foo/myfile.txt` and
-`compassionate_darwin:tmp/foo/myfile.txt` as identical. Local machine paths can
-be an absolute or relative value. The command interprets a local machine's
-relative paths as relative to the current working directory where `docker cp` is
-run.
-
-The `cp` command behaves like the Unix `cp -a` command in that directories are
-copied recursively with permissions preserved if possible. Ownership is set to
-the user and primary group at the destination. For example, files copied to a
-container are created with `UID:GID` of the root user. Files copied to the local
-machine are created with the `UID:GID` of the user which invoked the `docker cp`
-command.  If you specify the `-L` option, `docker cp` follows any symbolic link
-in the `SRC_PATH`.  `docker cp` does *not* create parent directories for
-`DEST_PATH` if they do not exist.
-
-Assuming a path separator of `/`, a first argument of `SRC_PATH` and second
-argument of `DEST_PATH`, the behavior is as follows:
-
-- `SRC_PATH` specifies a file
-    - `DEST_PATH` does not exist
-        - the file is saved to a file created at `DEST_PATH`
-    - `DEST_PATH` does not exist and ends with `/`
-        - Error condition: the destination directory must exist.
-    - `DEST_PATH` exists and is a file
-        - the destination is overwritten with the source file's contents
-    - `DEST_PATH` exists and is a directory
-        - the file is copied into this directory using the basename from
-          `SRC_PATH`
-- `SRC_PATH` specifies a directory
-    - `DEST_PATH` does not exist
-        - `DEST_PATH` is created as a directory and the *contents* of the source
-           directory are copied into this directory
-    - `DEST_PATH` exists and is a file
-        - Error condition: cannot copy a directory to a file
-    - `DEST_PATH` exists and is a directory
-        - `SRC_PATH` does not end with `/.` (that is: _slash_ followed by _dot_)
-            - the source directory is copied into this directory
-        - `SRC_PATH` does end with `/.` (that is: _slash_ followed by _dot_)
-            - the *content* of the source directory is copied into this
-              directory
-
-The command requires `SRC_PATH` and `DEST_PATH` to exist according to the above
-rules. If `SRC_PATH` is local and is a symbolic link, the symbolic link, not
-the target, is copied by default. To copy the link target and not the link, specify
-the `-L` option.
-
-A colon (`:`) is used as a delimiter between `CONTAINER` and its path. You can
-also use `:` when specifying paths to a `SRC_PATH` or `DEST_PATH` on a local
-machine, for example  `file:name.txt`. If you use a `:` in a local machine path,
-you must be explicit with a relative or absolute path, for example:
-
-    `/path/to/file:name.txt` or `./file:name.txt`
-
-It is not possible to copy certain system files such as resources under
-`/proc`, `/sys`, `/dev`, [tmpfs](run.md#mount-tmpfs-tmpfs), and mounts created by
-the user in the container. However, you can still copy such files by manually
-running `tar` in `docker exec`. Both of the following examples do the same thing
-in different ways (consider `SRC_PATH` and `DEST_PATH` are directories):
-
-```bash
-$ docker exec foo tar Ccf $(dirname SRC_PATH) - $(basename SRC_PATH) | tar Cxf DEST_PATH -
-```
-
-```bash
-$ tar Ccf $(dirname SRC_PATH) - $(basename SRC_PATH) | docker exec -i foo tar Cxf DEST_PATH -
-```
-
-Using `-` as the `SRC_PATH` streams the contents of `STDIN` as a tar archive.
-The command extracts the content of the tar to the `DEST_PATH` in container's
-filesystem. In this case, `DEST_PATH` must specify a directory. Using `-` as
-the `DEST_PATH` streams the contents of the resource as a tar archive to `STDOUT`.

-## Description
-
-The `docker create` command creates a writeable container layer over the
-specified image and prepares it for running the specified command.  The
-container ID is then printed to `STDOUT`.  This is similar to `docker run -d`
-except the container is never started.  You can then use the
-`docker start <container_id>` command to start the container at any point.
-
-This is useful when you want to set up a container configuration ahead of time
-so that it is ready to start when you need it. The initial status of the
-new container is `created`.
-
-Please see the [run command](run.md) section and the [Docker run reference](../run.md) for more details.
-
-## Examples
-
-### Create and start a container
-
-```bash
-$ docker create -t -i fedora bash
-
-6d8af538ec541dd581ebc2a24153a28329acb5268abe5ef868c1f1a261221752
-
-$ docker start -a -i 6d8af538ec5
-
-bash-4.2#
-```
-
-### Initialize volumes
-
-As of v1.4.0 container volumes are initialized during the `docker create` phase
-(i.e., `docker run` too). For example, this allows you to `create` the `data`
-volume container, and then use it from another container:
-
-```bash
-$ docker create -v /data --name data ubuntu
-
-240633dfbb98128fa77473d3d9018f6123b99c454b3251427ae190a7d951ad57
-
-$ docker run --rm --volumes-from data ubuntu ls -la /data
-
-total 8
-drwxr-xr-x  2 root root 4096 Dec  5 04:10 .
-drwxr-xr-x 48 root root 4096 Dec  5 04:11 ..
-```
-
-Similarly, `create` a host directory bind mounted volume container, which can
-then be used from the subsequent container:
-
-```bash
-$ docker create -v /home/docker:/docker --name docker ubuntu
-
-9aa88c08f319cd1e4515c3c46b0de7cc9aa75e878357b1e96f91e2c773029f03
-
-$ docker run --rm --volumes-from docker ubuntu ls -la /docker
-
-total 20
-drwxr-sr-x  5 1000 staff  180 Dec  5 04:00 .
-drwxr-xr-x 48 root root  4096 Dec  5 04:13 ..
--rw-rw-r--  1 1000 staff 3833 Dec  5 04:01 .ash_history
--rw-r--r--  1 1000 staff  446 Nov 28 11:51 .ashrc
--rw-r--r--  1 1000 staff   25 Dec  5 04:00 .gitconfig
-drwxr-sr-x  3 1000 staff   60 Dec  1 03:28 .local
--rw-r--r--  1 1000 staff  920 Nov 28 11:51 .profile
-drwx--S---  2 1000 staff  460 Dec  5 00:51 .ssh
-drwxr-xr-x 32 1000 staff 1140 Dec  5 04:01 docker
-```
-
-
-Set storage driver options per container.
-
-```bash
-$ docker create -it --storage-opt size=120G fedora /bin/bash
-```
-
-This (size) will allow to set the container rootfs size to 120G at creation time.
-This option is only available for the `devicemapper`, `btrfs`, `overlay2`,
-`windowsfilter` and `zfs` graph drivers.
-For the `devicemapper`, `btrfs`, `windowsfilter` and `zfs` graph drivers,
-user cannot pass a size less than the Default BaseFS Size.
-For the `overlay2` storage driver, the size option is only available if the
-backing fs is `xfs` and mounted with the `pquota` mount option.
-Under these conditions, user can pass any size less then the backing fs size.
-
-### Specify isolation technology for container (--isolation)
-
-This option is useful in situations where you are running Docker containers on
-Windows. The `--isolation=<value>` option sets a container's isolation
-technology. On Linux, the only supported is the `default` option which uses
-Linux namespaces. On Microsoft Windows, you can specify these values:
-
-
-| Value     | Description                                                                                                                                                   |
-|-----------|---------------------------------------------------------------------------------------------------------------------------------------------------------------|
-| `default` | Use the value specified by the Docker daemon's `--exec-opt` . If the `daemon` does not specify an isolation technology, Microsoft Windows uses `process` as its default value if the
-daemon is running on Windows server, or `hyperv` if running on Windows client.  |
-| `process` | Namespace isolation only.                                                                                                                                     |
-| `hyperv`   | Hyper-V hypervisor partition-based isolation.                                                                                                                  |
-
-Specifying the `--isolation` flag without a value is the same as setting `--isolation="default"`.
-
-### Dealing with dynamically created devices (--device-cgroup-rule)
-
-Devices available to a container are assigned at creation time. The
-assigned devices will both be added to the cgroup.allow file and
-created into the container once it is run. This poses a problem when
-a new device needs to be added to running container.
-
-One of the solution is to add a more permissive rule to a container
-allowing it access to a wider range of devices. For example, supposing
-our container needs access to a character device with major `42` and
-any number of minor number (added as new devices appear), the
-following rule would be added:
-
-```
-docker create --device-cgroup-rule='c 42:* rmw' -name my-container my-image
-```
-
-Then, a user could ask `udev` to execute a script that would `docker exec my-container mknod newDevX c 42 <minor>`
-the required device when it is added.
-
-NOTE: initially present devices still need to be explicitely added to
-the create/run command

-Inspect changes to files or directories on a container's filesystem
-
-Options:
-      --help   Print usage
-```
-
-## Description
-
-List the changed files and directories in a container᾿s filesystem since the
-container was created. Three different types of change are tracked:
-
-| Symbol | Description                     |
-|--------|---------------------------------|
-| `A`    | A file or directory was added   |
-| `D`    | A file or directory was deleted |
-| `C`    | A file or directory was changed |
-
-You can use the full or shortened container ID or the container name set using
-`docker run --name` option.
-
-## Examples
-
-Inspect the changes to an `nginx` container:
-
-```bash

-## Description
-
-`dockerd` is the persistent process that manages containers. Docker
-uses different binaries for the daemon and client. To run the daemon you
-type `dockerd`.
-
-To run the daemon with debug output, use `dockerd -D` or add `debug: true` to
-the `daemon.json` file.
-
-> **Note**: In Docker 1.13 and higher, enable experimental features by starting
-> `dockerd` with the `--experimental` flag or adding `experimental: true` to the
-> `daemon.json` file. In earlier Docker versions, a different build was required
-> to enable experimental features.
-
-## Examples
-
-### Daemon socket option
-
-The Docker daemon can listen for [Docker Engine API](../api/)
-requests via three different types of Socket: `unix`, `tcp`, and `fd`.
-
-By default, a `unix` domain socket (or IPC socket) is created at
-`/var/run/docker.sock`, requiring either `root` permission, or `docker` group
-membership.
-
-If you need to access the Docker daemon remotely, you need to enable the `tcp`
-Socket. Beware that the default setup provides un-encrypted and
-un-authenticated direct access to the Docker daemon - and should be secured
-either using the [built in HTTPS encrypted socket](https://docs.docker.com/engine/security/https/), or by
-putting a secure web proxy in front of it. You can listen on port `2375` on all
-network interfaces with `-H tcp://0.0.0.0:2375`, or on a particular network
-interface using its IP address: `-H tcp://192.168.59.103:2375`. It is
-conventional to use port `2375` for un-encrypted, and port `2376` for encrypted
-communication with the daemon.
-
-> **Note**: If you're using an HTTPS encrypted socket, keep in mind that only
-> TLS1.0 and greater are supported. Protocols SSLv3 and under are not
-> supported anymore for security reasons.
-
-On Systemd based systems, you can communicate with the daemon via
-[Systemd socket activation](http://0pointer.de/blog/projects/socket-activation.html),
-use `dockerd -H fd://`. Using `fd://` will work perfectly for most setups but
-you can also specify individual sockets: `dockerd -H fd://3`. If the
-specified socket activated files aren't found, then Docker will exit. You can
-find examples of using Systemd socket activation with Docker and Systemd in the
-[Docker source tree](https://github.com/docker/docker/tree/master/contrib/init/systemd/).
-
-You can configure the Docker daemon to listen to multiple sockets at the same
-time using multiple `-H` options:
-
-```bash
-# listen using the default unix socket, and on 2 specific IP addresses on this host.
-
-$ sudo dockerd -H unix:///var/run/docker.sock -H tcp://192.168.59.106 -H tcp://10.10.10.2
-```
-
-The Docker client will honor the `DOCKER_HOST` environment variable to set the
-`-H` flag for the client. Use **one** of the following commands:
-
-```bash
-$ docker -H tcp://0.0.0.0:2375 ps
-```
-
-```bash
-$ export DOCKER_HOST="tcp://0.0.0.0:2375"
-
-$ docker ps
-```
-
-Setting the `DOCKER_TLS_VERIFY` environment variable to any value other than
-the empty string is equivalent to setting the `--tlsverify` flag. The following
-are equivalent:
-
-```bash
-$ docker --tlsverify ps
-# or
-$ export DOCKER_TLS_VERIFY=1
-$ docker ps
-```
-
-The Docker client will honor the `HTTP_PROXY`, `HTTPS_PROXY`, and `NO_PROXY`
-environment variables (or the lowercase versions thereof). `HTTPS_PROXY` takes
-precedence over `HTTP_PROXY`.
-
-#### Bind Docker to another host/port or a Unix socket
-
-> **Warning**:
-> Changing the default `docker` daemon binding to a
-> TCP port or Unix *docker* user group will increase your security risks
-> by allowing non-root users to gain *root* access on the host. Make sure
-> you control access to `docker`. If you are binding
-> to a TCP port, anyone with access to that port has full Docker access;
-> so it is not advisable on an open network.
-
-With `-H` it is possible to make the Docker daemon to listen on a
-specific IP and port. By default, it will listen on
-`unix:///var/run/docker.sock` to allow only local connections by the
-*root* user. You *could* set it to `0.0.0.0:2375` or a specific host IP
-to give access to everybody, but that is **not recommended** because
-then it is trivial for someone to gain root access to the host where the
-daemon is running.
-
-Similarly, the Docker client can use `-H` to connect to a custom port.
-The Docker client will default to connecting to `unix:///var/run/docker.sock`
-on Linux, and `tcp://127.0.0.1:2376` on Windows.
-
-`-H` accepts host and port assignment in the following format:
-
-    tcp://[host]:[port][path] or unix://path
-
-For example:
-
--   `tcp://` -> TCP connection to `127.0.0.1` on either port `2376` when TLS encryption
-    is on, or port `2375` when communication is in plain text.
--   `tcp://host:2375` -> TCP connection on
-    host:2375
--   `tcp://host:2375/path` -> TCP connection on
-    host:2375 and prepend path to all requests
--   `unix://path/to/socket` -> Unix socket located
-    at `path/to/socket`
-
-`-H`, when empty, will default to the same value as
-when no `-H` was passed in.
-
-`-H` also accepts short form for TCP bindings: `host:` or `host:port` or `:port`
-
-Run Docker in daemon mode:
-
-```bash
-$ sudo <path to>/dockerd -H 0.0.0.0:5555 &
-```
-
-Download an `ubuntu` image:
-
-```bash
-$ docker -H :5555 pull ubuntu
-```
-
-You can use multiple `-H`, for example, if you want to listen on both
-TCP and a Unix socket
-
-```bash
-# Run docker in daemon mode
-$ sudo <path to>/dockerd -H tcp://127.0.0.1:2375 -H unix:///var/run/docker.sock &
-# Download an ubuntu image, use default Unix socket
-$ docker pull ubuntu
-# OR use the TCP port
-$ docker -H tcp://127.0.0.1:2375 pull ubuntu
-```
-
-### Daemon storage-driver
-
-The Docker daemon has support for several different image layer storage
-drivers: `aufs`, `devicemapper`, `btrfs`, `zfs`, `overlay` and `overlay2`.
-
-The `aufs` driver is the oldest, but is based on a Linux kernel patch-set that
-is unlikely to be merged into the main kernel. These are also known to cause
-some serious kernel crashes. However `aufs` allows containers to share
-executable and shared library memory, so is a useful choice when running
-thousands of containers with the same program or libraries.
-
-The `devicemapper` driver uses thin provisioning and Copy on Write (CoW)
-snapshots. For each devicemapper graph location – typically
-`/var/lib/docker/devicemapper` – a thin pool is created based on two block
-devices, one for data and one for metadata. By default, these block devices
-are created automatically by using loopback mounts of automatically created
-sparse files. Refer to [Storage driver options](#storage-driver-options) below
-for a way how to customize this setup.
-[~jpetazzo/Resizing Docker containers with the Device Mapper plugin](http://jpetazzo.github.io/2014/01/29/docker-device-mapper-resize/)
-article explains how to tune your existing setup without the use of options.
-
-The `btrfs` driver is very fast for `docker build` - but like `devicemapper`
-does not share executable memory between devices. Use
-`dockerd -s btrfs -g /mnt/btrfs_partition`.
-
-The `zfs` driver is probably not as fast as `btrfs` but has a longer track record
-on stability. Thanks to `Single Copy ARC` shared blocks between clones will be
-cached only once. Use `dockerd -s zfs`. To select a different zfs filesystem
-set `zfs.fsname` option as described in [Storage driver options](#storage-driver-options).
-
-The `overlay` is a very fast union filesystem. It is now merged in the main
-Linux kernel as of [3.18.0](https://lkml.org/lkml/2014/10/26/137). `overlay`
-also supports page cache sharing, this means multiple containers accessing
-the same file can share a single page cache entry (or entries), it makes
-`overlay` as efficient with memory as `aufs` driver. Call
-`dockerd -s overlay` to use it.
-
-> **Note**: As promising as `overlay` is, the feature is still quite young and
-> should not be used in production. Most notably, using `overlay` can cause
-> excessive inode consumption (especially as the number of images grows), as
-> well as > being incompatible with the use of RPMs.
-
-The `overlay2` uses the same fast union filesystem but takes advantage of
-[additional features](https://lkml.org/lkml/2015/2/11/106) added in Linux
-kernel 4.0 to avoid excessive inode consumption. Call `dockerd -s overlay2`
-to use it.
-
-> **Note**: Both `overlay` and `overlay2` are currently unsupported on `btrfs`
-> or any Copy on Write filesystem and should only be used over `ext4` partitions.
-
-### Options per storage driver
-
-Particular storage-driver can be configured with options specified with
-`--storage-opt` flags. Options for `devicemapper` are prefixed with `dm`,
-options for `zfs` start with `zfs` and options for `btrfs` start with `btrfs`.
-
-#### Devicemapper options
-
-This is an example of the configuration file for devicemapper on Linux:
-
-```json
-{
-  "storage-driver": "devicemapper",
-  "storage-opts": [
-    "dm.thinpooldev=/dev/mapper/thin-pool",
-    "dm.use_deferred_deletion=true",
-    "dm.use_deferred_removal=true"
-  ]
-}
-```
-
-##### `dm.thinpooldev`
-
-Specifies a custom block storage device to use for the thin pool.
-
-If using a block device for device mapper storage, it is best to use `lvm`
-to create and manage the thin-pool volume. This volume is then handed to Docker
-to exclusively create snapshot volumes needed for images and containers.
-
-Managing the thin-pool outside of Engine makes for the most feature-rich
-method of having Docker utilize device mapper thin provisioning as the
-backing storage for Docker containers. The highlights of the lvm-based
-thin-pool management feature include: automatic or interactive thin-pool
-resize support, dynamically changing thin-pool features, automatic thinp
-metadata checking when lvm activates the thin-pool, etc.
-
-As a fallback if no thin pool is provided, loopback files are
-created. Loopback is very slow, but can be used without any
-pre-configuration of storage. It is strongly recommended that you do
-not use loopback in production. Ensure your Engine daemon has a
-`--storage-opt dm.thinpooldev` argument provided.
-
-###### Example:
-
-```bash
-$ sudo dockerd --storage-opt dm.thinpooldev=/dev/mapper/thin-pool
-```
-
-##### `dm.directlvm_device`
-
-As an alternative to providing a thin pool as above, Docker can setup a block
-device for you.
-
-###### Example:
-
-```bash
-$ sudo dockerd --storage-opt dm.directlvm_device=/dev/xvdf
-```
-
-##### `dm.thinp_percent`
-
-Sets the percentage of passed in block device to use for storage.
-
-###### Example:
-
-```bash
-$ sudo dockerd --storage-opt dm.thinp_percent=95
-```
-
-##### `dm.thinp_metapercent`
-
-Sets the percentage of the passed in block device to use for metadata storage.
-
-###### Example:
-
-```bash
-$ sudo dockerd --storage-opt dm.thinp_metapercent=1
-```
-
-##### `dm.thinp_autoextend_threshold`
-
-Sets the value of the percentage of space used before `lvm` attempts to
-autoextend the available space [100 = disabled]
-
-###### Example:
-
-```bash
-$ sudo dockerd --storage-opt dm.thinp_autoextend_threshold=80
-```
-
-##### `dm.thinp_autoextend_percent`
-
-Sets the value percentage value to increase the thin pool by when when `lvm`
-attempts to autoextend the available space [100 = disabled]
-
-###### Example:
-
-```bash
-$ sudo dockerd --storage-opt dm.thinp_autoextend_percent=20
-```
-
-
-##### `dm.basesize`
-
-Specifies the size to use when creating the base device, which limits the
-size of images and containers. The default value is 10G. Note, thin devices
-are inherently "sparse", so a 10G device which is mostly empty doesn't use
-10 GB of space on the pool. However, the filesystem will use more space for
-the empty case the larger the device is.
-
-The base device size can be increased at daemon restart which will allow
-all future images and containers (based on those new images) to be of the
-new base device size.
-
-###### Examples
-
-```bash
-$ sudo dockerd --storage-opt dm.basesize=50G
-```
-
-This will increase the base device size to 50G. The Docker daemon will throw an
-error if existing base device size is larger than 50G. A user can use
-this option to expand the base device size however shrinking is not permitted.
-
-This value affects the system-wide "base" empty filesystem
-that may already be initialized and inherited by pulled images. Typically,
-a change to this value requires additional steps to take effect:
-
- ```bash
-$ sudo service docker stop
-
-$ sudo rm -rf /var/lib/docker
-
-$ sudo service docker start
-```
-
-
-##### `dm.loopdatasize`
-
-> **Note**: This option configures devicemapper loopback, which should not
-> be used in production.
-
-Specifies the size to use when creating the loopback file for the
-"data" device which is used for the thin pool. The default size is
-100G. The file is sparse, so it will not initially take up this
-much space.
-
-###### Example
-
-```bash
-$ sudo dockerd --storage-opt dm.loopdatasize=200G
-```
-
-##### `dm.loopmetadatasize`
-
-> **Note**: This option configures devicemapper loopback, which should not
-> be used in production.
-
-Specifies the size to use when creating the loopback file for the
-"metadata" device which is used for the thin pool. The default size
-is 2G. The file is sparse, so it will not initially take up
-this much space.
-
-###### Example
-
-```bash
-$ sudo dockerd --storage-opt dm.loopmetadatasize=4G
-```
-
-##### `dm.fs`
-
-Specifies the filesystem type to use for the base device. The supported
-options are "ext4" and "xfs". The default is "xfs"
-
-###### Example
-
-```bash
-$ sudo dockerd --storage-opt dm.fs=ext4
-```
-
-##### `dm.mkfsarg`
-
-Specifies extra mkfs arguments to be used when creating the base device.
-
-###### Example
-
-```bash
-$ sudo dockerd --storage-opt "dm.mkfsarg=-O ^has_journal"
-```
-
-##### `dm.mountopt`
-
-Specifies extra mount options used when mounting the thin devices.
-
-###### Example
-
-```bash
-$ sudo dockerd --storage-opt dm.mountopt=nodiscard
-```
-
-##### `dm.datadev`
-
-(Deprecated, use `dm.thinpooldev`)
-
-Specifies a custom blockdevice to use for data for the thin pool.
-
-If using a block device for device mapper storage, ideally both `datadev` and
-`metadatadev` should be specified to completely avoid using the loopback
-device.
-
-###### Example
-
-```bash
-$ sudo dockerd \
-      --storage-opt dm.datadev=/dev/sdb1 \
-      --storage-opt dm.metadatadev=/dev/sdc1
-```
-
-##### `dm.metadatadev`
-
-(Deprecated, use `dm.thinpooldev`)
-
-Specifies a custom blockdevice to use for metadata for the thin pool.
-
-For best performance the metadata should be on a different spindle than the
-data, or even better on an SSD.
-
-If setting up a new metadata pool it is required to be valid. This can be
-achieved by zeroing the first 4k to indicate empty metadata, like this:
-
-```bash
-$ dd if=/dev/zero of=$metadata_dev bs=4096 count=1
-```
-
-###### Example
-
-```bash
-$ sudo dockerd \
-      --storage-opt dm.datadev=/dev/sdb1 \
-      --storage-opt dm.metadatadev=/dev/sdc1
-```
-
-##### `dm.blocksize`
-
-Specifies a custom blocksize to use for the thin pool. The default
-blocksize is 64K.
-
-###### Example
-
-```bash
-$ sudo dockerd --storage-opt dm.blocksize=512K
-```
-
-##### `dm.blkdiscard`
-
-Enables or disables the use of `blkdiscard` when removing devicemapper
-devices. This is enabled by default (only) if using loopback devices and is
-required to resparsify the loopback file on image/container removal.
-
-Disabling this on loopback can lead to *much* faster container removal
-times, but will make the space used in `/var/lib/docker` directory not be
-returned to the system for other use when containers are removed.
-
-###### Examples
-
-```bash
-$ sudo dockerd --storage-opt dm.blkdiscard=false
-```
-
-##### `dm.override_udev_sync_check`
-
-Overrides the `udev` synchronization checks between `devicemapper` and `udev`.
-`udev` is the device manager for the Linux kernel.
-
-To view the `udev` sync support of a Docker daemon that is using the
-`devicemapper` driver, run:
-
-```bash
-$ docker info
-[...]
-Udev Sync Supported: true
-[...]
-```
-
-When `udev` sync support is `true`, then `devicemapper` and udev can
-coordinate the activation and deactivation of devices for containers.
-
-When `udev` sync support is `false`, a race condition occurs between
-the`devicemapper` and `udev` during create and cleanup. The race condition
-results in errors and failures. (For information on these failures, see
-[docker#4036](https://github.com/docker/docker/issues/4036))
-
-To allow the `docker` daemon to start, regardless of `udev` sync not being
-supported, set `dm.override_udev_sync_check` to true:
-
-```bash
-$ sudo dockerd --storage-opt dm.override_udev_sync_check=true
-```
-
-When this value is `true`, the  `devicemapper` continues and simply warns
-you the errors are happening.
-
-> **Note**: The ideal is to pursue a `docker` daemon and environment that does
-> support synchronizing with `udev`. For further discussion on this
-> topic, see [docker#4036](https://github.com/docker/docker/issues/4036).
-> Otherwise, set this flag for migrating existing Docker daemons to
-> a daemon with a supported environment.
-
-##### `dm.use_deferred_removal`
-
-Enables use of deferred device removal if `libdm` and the kernel driver
-support the mechanism.
-
-Deferred device removal means that if device is busy when devices are
-being removed/deactivated, then a deferred removal is scheduled on
-device. And devices automatically go away when last user of the device
-exits.
-
-For example, when a container exits, its associated thin device is removed.
-If that device has leaked into some other mount namespace and can't be
-removed, the container exit still succeeds and this option causes the
-system to schedule the device for deferred removal. It does not wait in a
-loop trying to remove a busy device.
-
-###### Example
-
-```bash
-$ sudo dockerd --storage-opt dm.use_deferred_removal=true
-```
-
-##### `dm.use_deferred_deletion`
-
-Enables use of deferred device deletion for thin pool devices. By default,
-thin pool device deletion is synchronous. Before a container is deleted,
-the Docker daemon removes any associated devices. If the storage driver
-can not remove a device, the container deletion fails and daemon returns.
-
-```none
-Error deleting container: Error response from daemon: Cannot destroy container
-```
-
-To avoid this failure, enable both deferred device deletion and deferred
-device removal on the daemon.
-
-```bash
-$ sudo dockerd \
-      --storage-opt dm.use_deferred_deletion=true \
-      --storage-opt dm.use_deferred_removal=true
-```
-
-With these two options enabled, if a device is busy when the driver is
-deleting a container, the driver marks the device as deleted. Later, when
-the device isn't in use, the driver deletes it.
-
-In general it should be safe to enable this option by default. It will help
-when unintentional leaking of mount point happens across multiple mount
-namespaces.
-
-##### `dm.min_free_space`
-
-Specifies the min free space percent in a thin pool require for new device
-creation to succeed. This check applies to both free data space as well
-as free metadata space. Valid values are from 0% - 99%. Value 0% disables
-free space checking logic. If user does not specify a value for this option,
-the Engine uses a default value of 10%.
-
-Whenever a new a thin pool device is created (during `docker pull` or during
-container creation), the Engine checks if the minimum free space is
-available. If sufficient space is unavailable, then device creation fails
-and any relevant `docker` operation fails.
-
-To recover from this error, you must create more free space in the thin pool
-to recover from the error. You can create free space by deleting some images
-and containers from the thin pool. You can also add more storage to the thin
-pool.
-
-To add more space to a LVM (logical volume management) thin pool, just add
-more storage to the volume group container thin pool; this should automatically
-resolve any errors. If your configuration uses loop devices, then stop the
-Engine daemon, grow the size of loop files and restart the daemon to resolve
-the issue.
-
-###### Example
-
-```bash
-$ sudo dockerd --storage-opt dm.min_free_space=10%
-```
-
-##### `dm.xfs_nospace_max_retries`
-
-Specifies the maximum number of retries XFS should attempt to complete
-IO when ENOSPC (no space) error is returned by underlying storage device.
-
-By default XFS retries infinitely for IO to finish and this can result
-in unkillable process. To change this behavior one can set
-xfs_nospace_max_retries to say 0 and XFS will not retry IO after getting
-ENOSPC and will shutdown filesystem.
-
-###### Example
-
-```bash
-$ sudo dockerd --storage-opt dm.xfs_nospace_max_retries=0
-```
-
-#### ZFS options
-
-##### `zfs.fsname`
-
-Set zfs filesystem under which docker will create its own datasets.
-By default docker will pick up the zfs filesystem where docker graph
-(`/var/lib/docker`) is located.
-
-###### Example
-
-```bash
-$ sudo dockerd -s zfs --storage-opt zfs.fsname=zroot/docker
-```
-
-#### Btrfs options
-
-##### `btrfs.min_space`
-
-Specifies the minimum size to use when creating the subvolume which is used
-for containers. If user uses disk quota for btrfs when creating or running
-a container with **--storage-opt size** option, docker should ensure the
-**size** cannot be smaller than **btrfs.min_space**.
-
-###### Example
-
-```bash
-$ sudo dockerd -s btrfs --storage-opt btrfs.min_space=10G
-```
-
-#### Overlay2 options
-
-##### `overlay2.override_kernel_check`
-
-Overrides the Linux kernel version check allowing overlay2. Support for
-specifying multiple lower directories needed by overlay2 was added to the
-Linux kernel in 4.0.0. However, some older kernel versions may be patched
-to add multiple lower directory support for OverlayFS. This option should
-only be used after verifying this support exists in the kernel. Applying
-this option on a kernel without this support will cause failures on mount.
-
-### Docker runtime execution options
-
-The Docker daemon relies on a
-[OCI](https://github.com/opencontainers/runtime-spec) compliant runtime
-(invoked via the `containerd` daemon) as its interface to the Linux
-kernel `namespaces`, `cgroups`, and `SELinux`.
-
-By default, the Docker daemon automatically starts `containerd`. If you want to
-control `containerd` startup, manually start `containerd` and pass the path to
-the `containerd` socket using the `--containerd` flag. For example:
-
-```bash
-$ sudo dockerd --containerd /var/run/dev/docker-containerd.sock
-```
-
-Runtimes can be registered with the daemon either via the
-configuration file or using the `--add-runtime` command line argument.
-
-The following is an example adding 2 runtimes via the configuration:
-
-```json
-{
-	"default-runtime": "runc",
-	"runtimes": {
-		"runc": {
-			"path": "runc"
-		},
-		"custom": {
-			"path": "/usr/local/bin/my-runc-replacement",
-			"runtimeArgs": [
-				"--debug"
-			]
-		}
-	}
-}
-```
-
-This is the same example via the command line:
-
-```bash
-$ sudo dockerd --add-runtime runc=runc --add-runtime custom=/usr/local/bin/my-runc-replacement
-```
-
-> **Note**: Defining runtime arguments via the command line is not supported.
-
-#### Options for the runtime
-
-You can configure the runtime using options specified
-with the `--exec-opt` flag. All the flag's options have the `native` prefix. A
-single `native.cgroupdriver` option is available.
-
-The `native.cgroupdriver` option specifies the management of the container's
-cgroups. You can only specify `cgroupfs` or `systemd`. If you specify
-`systemd` and it is not available, the system errors out. If you omit the
-`native.cgroupdriver` option,` cgroupfs` is used.
-
-This example sets the `cgroupdriver` to `systemd`:
-
-```bash
-$ sudo dockerd --exec-opt native.cgroupdriver=systemd
-```
-
-Setting this option applies to all containers the daemon launches.
-
-Also Windows Container makes use of `--exec-opt` for special purpose. Docker user
-can specify default container isolation technology with this, for example:
-
-```console
-> dockerd --exec-opt isolation=hyperv
-```
-
-Will make `hyperv` the default isolation technology on Windows. If no isolation
-value is specified on daemon start, on Windows client, the default is
-`hyperv`, and on Windows server, the default is `process`.
-
-#### Daemon DNS options
-
-To set the DNS server for all Docker containers, use:
-
-```bash
-$ sudo dockerd --dns 8.8.8.8
-```
-
-To set the DNS search domain for all Docker containers, use:
-
-```bash
-$ sudo dockerd --dns-search example.com
-```
-
-#### Allow push of nondistributable artifacts
-
-Some images (e.g., Windows base images) contain artifacts whose distribution is
-restricted by license. When these images are pushed to a registry, restricted
-artifacts are not included.
-
-To override this behavior for specific registries, use the
-`--allow-nondistributable-artifacts` option in one of the following forms:
-
-* `--allow-nondistributable-artifacts myregistry:5000` tells the Docker daemon
-  to push nondistributable artifacts to myregistry:5000.
-* `--allow-nondistributable-artifacts 10.1.0.0/16` tells the Docker daemon to
-  push nondistributable artifacts to all registries whose resolved IP address
-  is within the subnet described by the CIDR syntax.
-
-This option can be used multiple times.
-
-This option is useful when pushing images containing nondistributable artifacts
-to a registry on an air-gapped network so hosts on that network can pull the
-images without connecting to another server.
-
-> **Warning**: Nondistributable artifacts typically have restrictions on how
-> and where they can be distributed and shared. Only use this feature to push
-> artifacts to private registries and ensure that you are in compliance with
-> any terms that cover redistributing nondistributable artifacts.
-
-#### Insecure registries
-
-Docker considers a private registry either secure or insecure. In the rest of
-this section, *registry* is used for *private registry*, and `myregistry:5000`
-is a placeholder example for a private registry.
-
-A secure registry uses TLS and a copy of its CA certificate is placed on the
-Docker host at `/etc/docker/certs.d/myregistry:5000/ca.crt`. An insecure
-registry is either not using TLS (i.e., listening on plain text HTTP), or is
-using TLS with a CA certificate not known by the Docker daemon. The latter can
-happen when the certificate was not found under
-`/etc/docker/certs.d/myregistry:5000/`, or if the certificate verification
-failed (i.e., wrong CA).
-
-By default, Docker assumes all, but local (see local registries below),
-registries are secure. Communicating with an insecure registry is not possible
-if Docker assumes that registry is secure. In order to communicate with an
-insecure registry, the Docker daemon requires `--insecure-registry` in one of
-the following two forms:
-
-* `--insecure-registry myregistry:5000` tells the Docker daemon that
-  myregistry:5000 should be considered insecure.
-* `--insecure-registry 10.1.0.0/16` tells the Docker daemon that all registries
-  whose domain resolve to an IP address is part of the subnet described by the
-  CIDR syntax, should be considered insecure.
-
-The flag can be used multiple times to allow multiple registries to be marked
-as insecure.
-
-If an insecure registry is not marked as insecure, `docker pull`,
-`docker push`, and `docker search` will result in an error message prompting
-the user to either secure or pass the `--insecure-registry` flag to the Docker
-daemon as described above.
-
-Local registries, whose IP address falls in the 127.0.0.0/8 range, are
-automatically marked as insecure as of Docker 1.3.2. It is not recommended to
-rely on this, as it may change in the future.
-
-Enabling `--insecure-registry`, i.e., allowing un-encrypted and/or untrusted
-communication, can be useful when running a local registry.  However,
-because its use creates security vulnerabilities it should ONLY be enabled for
-testing purposes.  For increased security, users should add their CA to their
-system's list of trusted CAs instead of enabling `--insecure-registry`.
-
-##### Legacy Registries
-
-Operations against registries supporting only the legacy v1 protocol are
-disabled by default. Specifically, the daemon will not attempt `push`,
-`pull` and `login` to v1 registries. The exception to this is `search`
-which can still be performed on v1 registries.
-
-Add `"disable-legacy-registry":false` to the [daemon configuration
-file](#daemon-configuration-file), or set the
-`--disable-legacy-registry=false` flag, if you need to interact with
-registries that have not yet migrated to the v2 protocol.
-
-Interaction v1 registries will no longer be supported in Docker v17.12,
-and the `disable-legacy-registry` configuration option will be removed.
-
-#### Running a Docker daemon behind an HTTPS_PROXY
-
-When running inside a LAN that uses an `HTTPS` proxy, the Docker Hub
-certificates will be replaced by the proxy's certificates. These certificates
-need to be added to your Docker host's configuration:
-
-1. Install the `ca-certificates` package for your distribution
-2. Ask your network admin for the proxy's CA certificate and append them to
-   `/etc/pki/tls/certs/ca-bundle.crt`
-3. Then start your Docker daemon with `HTTPS_PROXY=http://username:password@proxy:port/ dockerd`.
-   The `username:` and `password@` are optional - and are only needed if your
-   proxy is set up to require authentication.
-
-This will only add the proxy and authentication to the Docker daemon's requests -
-your `docker build`s and running containers will need extra configuration to
-use the proxy
-
-#### Default `ulimit` settings
-
-`--default-ulimit` allows you to set the default `ulimit` options to use for
-all containers. It takes the same options as `--ulimit` for `docker run`. If
-these defaults are not set, `ulimit` settings will be inherited, if not set on
-`docker run`, from the Docker daemon. Any `--ulimit` options passed to
-`docker run` will overwrite these defaults.
-
-Be careful setting `nproc` with the `ulimit` flag as `nproc` is designed by Linux to
-set the maximum number of processes available to a user, not to a container. For details
-please check the [run](run.md) reference.
-
-#### Node discovery
-
-The `--cluster-advertise` option specifies the `host:port` or `interface:port`
-combination that this particular daemon instance should use when advertising
-itself to the cluster. The daemon is reached by remote hosts through this value.
-If you  specify an interface, make sure it includes the IP address of the actual
-Docker host. For Engine installation created through `docker-machine`, the
-interface is typically `eth1`.
-
-The daemon uses [libkv](https://github.com/docker/libkv/) to advertise
-the node within the cluster. Some key-value backends support mutual
-TLS. To configure the client TLS settings used by the daemon can be configured
-using the `--cluster-store-opt` flag, specifying the paths to PEM encoded
-files. For example:
-
-```bash
-$ sudo dockerd \
-    --cluster-advertise 192.168.1.2:2376 \
-    --cluster-store etcd://192.168.1.2:2379 \
-    --cluster-store-opt kv.cacertfile=/path/to/ca.pem \
-    --cluster-store-opt kv.certfile=/path/to/cert.pem \
-    --cluster-store-opt kv.keyfile=/path/to/key.pem
-```
-
-The currently supported cluster store options are:
-
-| Option                | Description |
-|-----------------------|-------------|
-| `discovery.heartbeat` | Specifies the heartbeat timer in seconds which is used by the daemon as a `keepalive` mechanism to make sure discovery module treats the node as alive in the cluster. If not configured, the default value is 20 seconds. |
-| `discovery.ttl`       | Specifies the TTL (time-to-live) in seconds which is used by the discovery module to timeout a node if a valid heartbeat is not received within the configured ttl value. If not configured, the default value is 60 seconds. |
-| `kv.cacertfile`       | Specifies the path to a local file with PEM encoded CA certificates to trust. |
-| `kv.certfile`         | Specifies the path to a local file with a PEM encoded certificate. This certificate is used as the client cert for communication with the Key/Value store. |
-| `kv.keyfile`          | Specifies the path to a local file with a PEM encoded private key. This private key is used as the client key for communication with the Key/Value store. |
-| `kv.path`             | Specifies the path in the Key/Value store. If not configured, the default value is 'docker/nodes'. |

-#### Access authorization
-
-Docker's access authorization can be extended by authorization plugins that your
-organization can purchase or build themselves. You can install one or more
-authorization plugins when you start the Docker `daemon` using the
-`--authorization-plugin=PLUGIN_ID` option.
-
-```bash
-$ sudo dockerd --authorization-plugin=plugin1 --authorization-plugin=plugin2,...
-```
-
-The `PLUGIN_ID` value is either the plugin's name or a path to its specification
-file. The plugin's implementation determines whether you can specify a name or
-path. Consult with your Docker administrator to get information about the
-plugins available to you.
-
-Once a plugin is installed, requests made to the `daemon` through the
-command line or Docker's Engine API are allowed or denied by the plugin.
-If you have multiple plugins installed, each plugin, in order, must
-allow the request for it to complete.
-
-For information about how to create an authorization plugin, see [authorization
-plugin](../../extend/plugins_authorization.md) section in the Docker extend section of this documentation.
-
-
-#### Daemon user namespace options
-
-The Linux kernel [user namespace support](http://man7.org/linux/man-pages/man7/user_namespaces.7.html) provides additional security by enabling
-a process, and therefore a container, to have a unique range of user and
-group IDs which are outside the traditional user and group range utilized by
-the host system. Potentially the most important security improvement is that,
-by default, container processes running as the `root` user will have expected
-administrative privilege (with some restrictions) inside the container but will
-effectively be mapped to an unprivileged `uid` on the host.
-
-When user namespace support is enabled, Docker creates a single daemon-wide mapping
-for all containers running on the same engine instance. The mappings will
-utilize the existing subordinate user and group ID feature available on all modern
-Linux distributions.
-The [`/etc/subuid`](http://man7.org/linux/man-pages/man5/subuid.5.html) and
-[`/etc/subgid`](http://man7.org/linux/man-pages/man5/subgid.5.html) files will be
-read for the user, and optional group, specified to the `--userns-remap`
-parameter.  If you do not wish to specify your own user and/or group, you can
-provide `default` as the value to this flag, and a user will be created on your behalf
-and provided subordinate uid and gid ranges. This default user will be named
-`dockremap`, and entries will be created for it in `/etc/passwd` and
-`/etc/group` using your distro's standard user and group creation tools.
-
-> **Note**: The single mapping per-daemon restriction is in place for now
-> because Docker shares image layers from its local cache across all
-> containers running on the engine instance.  Since file ownership must be
-> the same for all containers sharing the same layer content, the decision
-> was made to map the file ownership on `docker pull` to the daemon's user and
-> group mappings so that there is no delay for running containers once the
-> content is downloaded. This design preserves the same performance for `docker
-> pull`, `docker push`, and container startup as users expect with
-> user namespaces disabled.
-
-##### Start the daemon with user namespaces enabled
-
-To enable user namespace support, start the daemon with the
-`--userns-remap` flag, which accepts values in the following formats:
-
- - uid
- - uid:gid
- - username
- - username:groupname
-
-If numeric IDs are provided, translation back to valid user or group names
-will occur so that the subordinate uid and gid information can be read, given
-these resources are name-based, not id-based.  If the numeric ID information
-provided does not exist as entries in `/etc/passwd` or `/etc/group`, daemon
-startup will fail with an error message.
-
-**Example: starting with default Docker user management:**
-
-```bash
-$ sudo dockerd --userns-remap=default
-```
-
-When `default` is provided, Docker will create - or find the existing - user and group
-named `dockremap`. If the user is created, and the Linux distribution has
-appropriate support, the `/etc/subuid` and `/etc/subgid` files will be populated
-with a contiguous 65536 length range of subordinate user and group IDs, starting
-at an offset based on prior entries in those files.  For example, Ubuntu will
-create the following range, based on an existing user named `user1` already owning
-the first 65536 range:
-
-```bash
-$ cat /etc/subuid
-user1:100000:65536
-dockremap:165536:65536
-```
-
-If you have a preferred/self-managed user with subordinate ID mappings already
-configured, you can provide that username or uid to the `--userns-remap` flag.
-If you have a group that doesn't match the username, you may provide the `gid`
-or group name as well; otherwise the username will be used as the group name
-when querying the system for the subordinate group ID range.
-
-The output of `docker info` can be used to determine if the daemon is running
-with user namespaces enabled or not. If the daemon is configured with user
-namespaces, the Security Options entry in the response will list "userns" as
-one of the enabled security features.
-
-##### Behavior differences when user namespaces are enabled
-
-When you start the Docker daemon with `--userns-remap`, Docker segregates the graph directory
-where the images are stored by adding an extra directory with a name corresponding to the
-remapped UID and GID. For example, if the remapped UID and GID begin with `165536`, all
-images and containers running with that remap setting are located in `/var/lib/docker/165536.165536`
-instead of `/var/lib/docker/`.
-
-In addition, the files and directories within the new directory, which correspond to
-images and container layers, are also owned by the new UID and GID. To set the ownership
-correctly, you need to re-pull the images and restart the containers after starting the
-daemon with `--userns-remap`.
-
-##### Detailed information on `subuid`/`subgid` ranges
-
-Given potential advanced use of the subordinate ID ranges by power users, the
-following paragraphs define how the Docker daemon currently uses the range entries
-found within the subordinate range files.
-
-The simplest case is that only one contiguous range is defined for the
-provided user or group. In this case, Docker will use that entire contiguous
-range for the mapping of host uids and gids to the container process.  This
-means that the first ID in the range will be the remapped root user, and the
-IDs above that initial ID will map host ID 1 through the end of the range.
-
-From the example `/etc/subuid` content shown above, the remapped root
-user would be uid 165536.
-
-If the system administrator has set up multiple ranges for a single user or
-group, the Docker daemon will read all the available ranges and use the
-following algorithm to create the mapping ranges:
-
-1. The range segments found for the particular user will be sorted by *start ID* ascending.
-2. Map segments will be created from each range in increasing value with a length matching the length of each segment. Therefore the range segment with the lowest numeric starting value will be equal to the remapped root, and continue up through host uid/gid equal to the range segment length. As an example, if the lowest segment starts at ID 1000 and has a length of 100, then a map of 1000 -> 0 (the remapped root) up through 1100 -> 100 will be created from this segment. If the next segment starts at ID 10000, then the next map will start with mapping 10000 -> 101 up to the length of this second segment. This will continue until no more segments are found in the subordinate files for this user.
-3. If more than five range segments exist for a single user, only the first five will be utilized, matching the kernel's limitation of only five entries in `/proc/self/uid_map` and `proc/self/gid_map`.
-
-##### Disable user namespace for a container
-
-If you enable user namespaces on the daemon, all containers are started
-with user namespaces enabled. In some situations you might want to disable
-this feature for a container, for example, to start a privileged container (see
-[user namespace known restrictions](#user-namespace-known-restrictions)).
-To enable those advanced features for a specific container use `--userns=host`
-in the `run/exec/create` command.
-This option will completely disable user namespace mapping for the container's user.
-
-##### User namespace known restrictions
-
-The following standard Docker features are currently incompatible when
-running a Docker daemon with user namespaces enabled:
-
- - sharing PID or NET namespaces with the host (`--pid=host` or `--net=host`)
- - Using `--privileged` mode flag on `docker run` (unless also specifying `--userns=host`)
-
-In general, user namespaces are an advanced feature and will require
-coordination with other capabilities. For example, if volumes are mounted from
-the host, file ownership will have to be pre-arranged if the user or
-administrator wishes the containers to have expected access to the volume
-contents. Note that when using external volume or graph driver plugins, those
-external software programs must be made aware of user and group mapping ranges
-if they are to work seamlessly with user namespace support.
-
-Finally, while the `root` user inside a user namespaced container process has
-many of the expected admin privileges that go along with being the superuser, the
-Linux kernel has restrictions based on internal knowledge that this is a user namespaced
-process. The most notable restriction that we are aware of at this time is the
-inability to use `mknod`. Permission will be denied for device creation even as
-container `root` inside a user namespace.
-
-### Miscellaneous options
-
-IP masquerading uses address translation to allow containers without a public
-IP to talk to other machines on the Internet. This may interfere with some
-network topologies and can be disabled with `--ip-masq=false`.
-
-Docker supports softlinks for the Docker data directory (`/var/lib/docker`) and
-for `/var/lib/docker/tmp`. The `DOCKER_TMPDIR` and the data directory can be
-set like this:
-
-    DOCKER_TMPDIR=/mnt/disk2/tmp /usr/local/bin/dockerd -D -g /var/lib/docker -H unix:// > /var/lib/docker-machine/docker.log 2>&1
-    # or
-    export DOCKER_TMPDIR=/mnt/disk2/tmp
-    /usr/local/bin/dockerd -D -g /var/lib/docker -H unix:// > /var/lib/docker-machine/docker.log 2>&1
-
-#### Default cgroup parent
-
-The `--cgroup-parent` option allows you to set the default cgroup parent
-to use for containers. If this option is not set, it defaults to `/docker` for
-fs cgroup driver and `system.slice` for systemd cgroup driver.
-
-If the cgroup has a leading forward slash (`/`), the cgroup is created
-under the root cgroup, otherwise the cgroup is created under the daemon
-cgroup.
-
-Assuming the daemon is running in cgroup `daemoncgroup`,
-`--cgroup-parent=/foobar` creates a cgroup in
-`/sys/fs/cgroup/memory/foobar`, whereas using `--cgroup-parent=foobar`
-creates the cgroup in `/sys/fs/cgroup/memory/daemoncgroup/foobar`
-
-The systemd cgroup driver has different rules for `--cgroup-parent`. Systemd
-represents hierarchy by slice and the name of the slice encodes the location in
-the tree. So `--cgroup-parent` for systemd cgroups should be a slice name. A
-name can consist of a dash-separated series of names, which describes the path
-to the slice from the root slice. For example, `--cgroup-parent=user-a-b.slice`
-means the memory cgroup for the container is created in
-`/sys/fs/cgroup/memory/user.slice/user-a.slice/user-a-b.slice/docker-<id>.scope`.
-
-This setting can also be set per container, using the `--cgroup-parent`
-option on `docker create` and `docker run`, and takes precedence over
-the `--cgroup-parent` option on the daemon.
-
-#### Daemon metrics
-
-The `--metrics-addr` option takes a tcp address to serve the metrics API.
-This feature is still experimental, therefore, the daemon must be running in experimental
-mode for this feature to work.
-
-To serve the metrics API on localhost:1337 you would specify `--metrics-addr 127.0.0.1:1337`
-allowing you to make requests on the API at `127.0.0.1:1337/metrics` to receive metrics in the
-[prometheus](https://prometheus.io/docs/instrumenting/exposition_formats/) format.
-
-If you are running a prometheus server you can add this address to your scrape configs
-to have prometheus collect metrics on Docker.  For more information
-on prometheus you can view the website [here](https://prometheus.io/).
-
-```none
-scrape_configs:
-  - job_name: 'docker'
-    static_configs:
-      - targets: ['127.0.0.1:1337']
-```
-
-Please note that this feature is still marked as experimental as metrics and metric
-names could change while this feature is still in experimental.  Please provide
-feedback on what you would like to see collected in the API.
-
-#### Daemon configuration file
-
-The `--config-file` option allows you to set any configuration option
-for the daemon in a JSON format. This file uses the same flag names as keys,
-except for flags that allow several entries, where it uses the plural
-of the flag name, e.g., `labels` for the `label` flag.
-
-The options set in the configuration file must not conflict with options set
-via flags. The docker daemon fails to start if an option is duplicated between
-the file and the flags, regardless their value. We do this to avoid
-silently ignore changes introduced in configuration reloads.
-For example, the daemon fails to start if you set daemon labels
-in the configuration file and also set daemon labels via the `--label` flag.
-Options that are not present in the file are ignored when the daemon starts.
-
-##### On Linux
-
-The default location of the configuration file on Linux is
-`/etc/docker/daemon.json`. The `--config-file` flag can be used to specify a
- non-default location.
-
-This is a full example of the allowed configuration options on Linux:
-
-```json

-```
-
-> **Note:** You cannot set options in `daemon.json` that have already been set on
-> daemon startup as a flag.
-> On systems that use `systemd` to start the Docker daemon, `-H` is already set, so
-> you cannot use the `hosts` key in `daemon.json` to add listening addresses.
-> See https://docs.docker.com/engine/admin/systemd/#custom-docker-daemon-options for how
-> to accomplish this task with a systemd drop-in file.
-
-##### On Windows
-
-The default location of the configuration file on Windows is
- `%programdata%\docker\config\daemon.json`. The `--config-file` flag can be
- used to specify a non-default location.
-
-This is a full example of the allowed configuration options on Windows:
-
-```json
-{
-    "authorization-plugins": [],
-    "data-root": "",
-    "dns": [],
-    "dns-opts": [],
-    "dns-search": [],
-    "exec-opts": [],
-    "experimental": false,
-    "storage-driver": "",
-    "storage-opts": [],
-    "labels": [],
-    "log-driver": "",
-    "mtu": 0,

-    "cluster-advertise": "",
-    "max-concurrent-downloads": 3,
-    "max-concurrent-uploads": 5,
-    "shutdown-timeout": 15,
-    "debug": true,
-    "hosts": [],

-    "allow-nondistributable-artifacts": [],
-    "registry-mirrors": [],
-    "insecure-registries": [],
-    "disable-legacy-registry": false
-}
-```
-
-#### Configuration reload behavior
-
-Some options can be reconfigured when the daemon is running without requiring
-to restart the process. We use the `SIGHUP` signal in Linux to reload, and a global event
-in Windows with the key `Global\docker-daemon-config-$PID`. The options can
-be modified in the configuration file but still will check for conflicts with
-the provided flags. The daemon fails to reconfigure itself
-if there are conflicts, but it won't stop execution.
-
-The list of currently supported options that can be reconfigured is this:
-
-- `debug`: it changes the daemon to debug mode when set to true.
-- `cluster-store`: it reloads the discovery store with the new address.
-- `cluster-store-opts`: it uses the new options to reload the discovery store.
-- `cluster-advertise`: it modifies the address advertised after reloading.
-- `labels`: it replaces the daemon labels with a new set of labels.
-- `live-restore`: Enables [keeping containers alive during daemon downtime](https://docs.docker.com/engine/admin/live-restore/).
-- `max-concurrent-downloads`: it updates the max concurrent downloads for each pull.
-- `max-concurrent-uploads`: it updates the max concurrent uploads for each push.
-- `default-runtime`: it updates the runtime to be used if not is
-  specified at container creation. It defaults to "default" which is
-  the runtime shipped with the official docker packages.
-- `runtimes`: it updates the list of available OCI runtimes that can
-  be used to run containers
-- `authorization-plugin`: specifies the authorization plugins to use.
-- `allow-nondistributable-artifacts`: Replaces the set of registries to which the daemon will push nondistributable artifacts with a new set of registries.
-- `insecure-registries`: it replaces the daemon insecure registries with a new set of insecure registries. If some existing insecure registries in daemon's configuration are not in newly reloaded insecure resgitries, these existing ones will be removed from daemon's config.
-- `registry-mirrors`: it replaces the daemon registry mirrors with a new set of registry mirrors. If some existing registry mirrors in daemon's configuration are not in newly reloaded registry mirrors, these existing ones will be removed from daemon's config.
-
-Updating and reloading the cluster configurations such as `--cluster-store`,
-`--cluster-advertise` and `--cluster-store-opts` will take effect only if
-these configurations were not previously configured. If `--cluster-store`
-has been provided in flags and `cluster-advertise` not, `cluster-advertise`
-can be added in the configuration file without accompanied by `--cluster-store`.
-Configuration reload will log a warning message if it detects a change in
-previously configured cluster configurations.
-
-
-### Run multiple daemons
-
-> **Note:** Running multiple daemons on a single host is considered as "experimental". The user should be aware of
-> unsolved problems. This solution may not work properly in some cases. Solutions are currently under development
-> and will be delivered in the near future.
-
-This section describes how to run multiple Docker daemons on a single host. To
-run multiple daemons, you must configure each daemon so that it does not
-conflict with other daemons on the same host. You can set these options either
-by providing them as flags, or by using a [daemon configuration file](#daemon-configuration-file).
-
-The following daemon options must be configured for each daemon:
-
-```none
--b, --bridge=                          Attach containers to a network bridge
---exec-root=/var/run/docker            Root of the Docker execdriver
---data-root=/var/lib/docker            Root of persisted Docker data
--p, --pidfile=/var/run/docker.pid      Path to use for daemon PID file
--H, --host=[]                          Daemon socket(s) to connect to
---iptables=true                        Enable addition of iptables rules
---config-file=/etc/docker/daemon.json  Daemon configuration file
---tlscacert="~/.docker/ca.pem"         Trust certs signed only by this CA
---tlscert="~/.docker/cert.pem"         Path to TLS certificate file
---tlskey="~/.docker/key.pem"           Path to TLS key file
-```
-
-When your daemons use different values for these flags, you can run them on the same host without any problems.
-It is very important to properly understand the meaning of those options and to use them correctly.
-
-- The `-b, --bridge=` flag is set to `docker0` as default bridge network. It is created automatically when you install Docker.
-If you are not using the default, you must create and configure the bridge manually or just set it to 'none': `--bridge=none`
-- `--exec-root` is the path where the container state is stored. The default value is `/var/run/docker`. Specify the path for
-your running daemon here.
-- `--data-root` is the path where persisted data such as images, volumes, and
-cluster state are stored. The default value is `/var/lib/docker`. To avoid any
-conflict with other daemons, set this parameter separately for each daemon.
-- `-p, --pidfile=/var/run/docker.pid` is the path where the process ID of the daemon is stored. Specify the path for your
-pid file here.
-- `--host=[]` specifies where the Docker daemon will listen for client connections. If unspecified, it defaults to `/var/run/docker.sock`.
--  `--iptables=false` prevents the Docker daemon from adding iptables rules. If
-multiple daemons manage iptables rules, they may overwrite rules set by another
-daemon. Be aware that disabling this option requires you to manually add
-iptables rules to expose container ports. If you prevent Docker from adding
-iptables rules, Docker will also not add IP masquerading rules, even if you set
-`--ip-masq` to `true`. Without IP masquerading rules, Docker containers will not be
-able to connect to external hosts or the internet when using network other than
-default bridge.
-- `--config-file=/etc/docker/daemon.json` is the path where configuration file is stored. You can use it instead of
-daemon flags. Specify the path for each daemon.
-- `--tls*` Docker daemon supports `--tlsverify` mode that enforces encrypted and authenticated remote connections.
-The `--tls*` options enable use of specific certificates for individual daemons.
-
-Example script for a separate “bootstrap” instance of the Docker daemon without network:
-
-```bash
-$ sudo dockerd \
-        -H unix:///var/run/docker-bootstrap.sock \
-        -p /var/run/docker-bootstrap.pid \
-        --iptables=false \
-        --ip-masq=false \
-        --bridge=none \
-        --data-root=/var/lib/docker-bootstrap \
-        --exec-root=/var/run/docker-bootstrap
-```

-
-## Description
-
-Use `docker events` to get real-time events from the server. These events differ
-per Docker object type.
-
-### Object types
-
-#### Containers
-
-Docker containers report the following events:
-
-- `attach`
-- `commit`

-### Limiting, filtering, and formatting the output
-
-#### Limit events by time
-
-The `--since` and `--until` parameters can be Unix timestamps, date formatted
-timestamps, or Go duration strings (e.g. `10m`, `1h30m`) computed
-relative to the client machine’s time. If you do not provide the `--since` option,
-the command returns only new and/or live events.  Supported formats for date
-formatted time stamps include RFC3339Nano, RFC3339, `2006-01-02T15:04:05`,
-`2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
-timezone on the client will be used if you do not provide either a `Z` or a
-`+-00:00` timezone offset at the end of the timestamp.  When providing Unix
-timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
-that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
-seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
-fraction of a second no more than nine digits long.
-
-#### Filtering
-
-The filtering flag (`-f` or `--filter`) format is of "key=value". If you would
-like to use multiple filters, pass multiple flags (e.g.,
-`--filter "foo=bar" --filter "bif=baz"`)
-
-Using the same filter multiple times will be handled as a *OR*; for example
-`--filter container=588a23dac085 --filter container=a8f7720b8c22` will display
-events for container 588a23dac085 *OR* container a8f7720b8c22
-
-Using multiple filters will be handled as a *AND*; for example
-`--filter container=588a23dac085 --filter event=start` will display events for
-container container 588a23dac085 *AND* the event type is *start*
-
-The currently supported filters are:
-
-* container (`container=<name or id>`)
-* daemon (`daemon=<name or id>`)
-* event (`event=<event action>`)
-* image (`image=<tag or id>`)
-* label (`label=<key>` or `label=<key>=<value>`)
-* network (`network=<name or id>`)
-* plugin (`plugin=<name or id>`)
-* type (`type=<container or image or volume or network or daemon or plugin>`)
-* volume (`volume=<name or id>`)
-
-#### Format
-
-If a format (`--format`) is specified, the given template will be executed
-instead of the default
-format. Go's [text/template](http://golang.org/pkg/text/template/) package
-describes all the details of the format.
-
-If a format is set to `{{json .}}`, the events are streamed as valid JSON
-Lines. For information about JSON Lines, please refer to http://jsonlines.org/ .
-
-## Examples
-
-### Basic example
-
-You'll need two shells for this example.
-
-**Shell 1: Listening for events:**
-
-```bash
-$ docker events
-```
-
-**Shell 2: Start and Stop containers:**
-
-```bash
-$ docker create --name test alpine:latest top
-$ docker start test
-$ docker stop test
-```
-
-**Shell 1: (Again .. now showing events):**
-
-```none
-2017-01-05T00:35:58.859401177+08:00 container create 0fdb48addc82871eb34eb23a847cfd033dedd1a0a37bef2e6d9eb3870fc7ff37 (image=alpine:latest, name=test)

-2017-01-05T00:36:09.890214053+08:00 container stop 0fdb...ff37 (image=alpine:latest, name=test)
-```
-
-To exit the `docker events` command, use `CTRL+C`.
-
-### Filter events by time
-
-You can filter the output by an absolute timestamp or relative time on the host
-machine, using the following different time syntaxes:
-
-```bash

-The command started using `docker exec` only runs while the container's primary
-process (`PID 1`) is running, and it is not restarted if the container is
-restarted.
-
-COMMAND will run in the default directory of the container. It the
-underlying image has a custom directory specified with the WORKDIR directive
-in its Dockerfile, this will be used instead.
-
-COMMAND should be an executable, a chained or a quoted command
-will not work. Example: `docker exec -ti my_container "echo a && echo b"` will
-not work, but `docker exec -ti my_container sh -c "echo a && echo b"` will.
-
-## Examples
-
-### Run `docker exec` on a running container
-
-First, start a container.
-
-```bash
-$ docker run --name ubuntu_bash --rm -i -t ubuntu bash
-```
-
-This will create a container named `ubuntu_bash` and start a Bash session.
-
-Next, execute a command on the container.
-
-```bash
-$ docker exec -d ubuntu_bash touch /tmp/execWorks
-```
-
-This will create a new file `/tmp/execWorks` inside the running container
-`ubuntu_bash`, in the background.
-
-Next, execute an interactive `bash` shell on the container.
-
-```bash
-$ docker exec -it ubuntu_bash bash
-```
-
-This will create a new Bash session in the container `ubuntu_bash`.
-
-### Try to run `docker exec` on a paused container
-
-If the container is paused, then the `docker exec` command will fail with an error:
-
-```bash
-$ docker pause test
-
-test
-
-$ docker ps
-

-# export
-
-```markdown
-Usage:  docker export [OPTIONS] CONTAINER
-
-Export a container's filesystem as a tar archive
-
-Options:
-      --help            Print usage
-  -o, --output string   Write to a file, instead of STDOUT
-```
-
-## Description
-
-The `docker export` command does not export the contents of volumes associated
-with the container. If a volume is mounted on top of an existing directory in
-the container, `docker export` will export the contents of the *underlying*
-directory, not the contents of the volume.
-
-Refer to [Backup, restore, or migrate data volumes](https://docs.docker.com/engine/tutorials/dockervolumes/#backup-restore-or-migrate-data-volumes)
-in the user guide for examples on exporting data in a volume.
-
-## Examples
-
-Each of these commands has the same result.
-
-```bash
-$ docker export red_panda > latest.tar
-```
-
-```bash
-$ docker export --output="latest.tar" red_panda
-```

-
-### Format the output
-
-The formatting option (`--format`) will pretty-prints history output
-using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-| Placeholder     | Description |
-| --------------- | ----------- |
-| `.ID`           | Image ID    |
-| `.CreatedSince` | Elapsed time since the image was created if `--human=true`, otherwise timestamp of when image was created |
-| `.CreatedAt`    | Timestamp of when image was created |
-| `.CreatedBy`    | Command that was used to create the image |
-| `.Size`         | Image disk size |
-| `.Comment`      | Comment for image |
-
-When using the `--format` option, the `history` command will either
-output the data exactly as the template declares or, when using the
-`table` directive, will include column headers as well.
-
-The following example uses a template without headers and outputs the
-`ID` and `CreatedSince` entries separated by a colon for all images:
-
-```bash
-$ docker images --format "{{.ID}}: {{.Created}} ago"
-

-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
-than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
-
-The currently supported filters are:
-
-* until (`<timestamp>`) - only remove images created before given timestamp
-* label (`label=<key>`, `label=<key>=<value>`, `label!=<key>`, or `label!=<key>=<value>`) - only remove images with (or without, in case `label!=...` is used) the specified labels.
-
-The `until` filter can be Unix timestamps, date formatted
-timestamps, or Go duration strings (e.g. `10m`, `1h30m`) computed
-relative to the daemon machine’s time. Supported formats for date
-formatted time stamps include RFC3339Nano, RFC3339, `2006-01-02T15:04:05`,
-`2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
-timezone on the daemon will be used if you do not provide either a `Z` or a
-`+-00:00` timezone offset at the end of the timestamp.  When providing Unix
-timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
-that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
-seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
-fraction of a second no more than nine digits long.
-
-The `label` filter accepts two formats. One is the `label=...` (`label=<key>` or `label=<key>=<value>`),
-which removes images with the specified labels. The other
-format is the `label!=...` (`label!=<key>` or `label!=<key>=<value>`), which removes
-images without the specified labels.
-
-The following removes images created before `2017-01-04T00:00:00`:
-
-```bash
-$ docker images --format 'table {{.Repository}}\t{{.Tag}}\t{{.ID}}\t{{.CreatedAt}}\t{{.Size}}'

-## Description
-
-The default `docker images` will show all top level
-images, their repository and tags, and their size.
-
-Docker images have intermediate layers that increase reusability,
-decrease disk usage, and speed up `docker build` by
-allowing each step to be cached. These intermediate layers are not shown
-by default.
-
-The `SIZE` is the cumulative space taken up by the image and all
-its parent images. This is also the disk space used by the contents of the
-Tar file created when you `docker save` an image.
-
-An image will be listed more than once if it has multiple repository names
-or tags. This single image (identifiable by its matching `IMAGE ID`)
-uses up the `SIZE` listed only once.
-

-
-### List images by name and tag
-
-The `docker images` command takes an optional `[REPOSITORY[:TAG]]` argument
-that restricts the list to images that match the argument. If you specify
-`REPOSITORY`but no `TAG`, the `docker images` command lists all images in the
-given repository.
-
-For example, to list all images in the "java" repository, run this command :
-
-```bash
-$ docker images java
-
-REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
-java                8                   308e519aac60        6 days ago          824.5 MB
-java                7                   493d82594c15        3 months ago        656.3 MB
-java                latest              2711b1d6f3aa        5 months ago        603.9 MB
-```
-
-The `[REPOSITORY[:TAG]]` value must be an "exact match". This means that, for example,
-`docker images jav` does not match the image `java`.
-
-If both `REPOSITORY` and `TAG` are provided, only images matching that
-repository and tag are listed.  To find all local images in the "java"
-repository with tag "8" you can use:
-
-```bash
-$ docker images java:8
-
-REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
-java                8                   308e519aac60        6 days ago          824.5 MB
-```
-
-If nothing matches `REPOSITORY[:TAG]`, the list is empty.
-
-```bash
-$ docker images java:0
-
-REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
-```
-
-### List the full length image IDs
-
-```bash
-$ docker images --no-trunc
-
-REPOSITORY                    TAG                 IMAGE ID                                                                  CREATED             SIZE

-
-### List image digests
-
-Images that use the v2 or later format have a content-addressable identifier
-called a `digest`. As long as the input used to generate the image is
-unchanged, the digest value is predictable. To list image digest values, use
-the `--digests` flag:
-
-```bash
-$ docker images --digests
-REPOSITORY                         TAG                 DIGEST                                                                    IMAGE ID            CREATED             SIZE
-localhost:5000/test/busybox        <none>              sha256:cbbf2f9a99b47fc460d422812b6a5adff7dfee951d8fa2e4a98caa0382cfbdbf   4986bf8c1536        9 weeks ago         2.43 MB
-```
-
-When pushing or pulling to a 2.0 registry, the `push` or `pull` command
-output includes the image digest. You can `pull` using a digest value. You can
-also reference by digest in `create`, `run`, and `rmi` commands, as well as the
-`FROM` image reference in a Dockerfile.
-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
-than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
-
-The currently supported filters are:
-
-* dangling (boolean - true or false)
-* label (`label=<key>` or `label=<key>=<value>`)
-* before (`<image-name>[:<tag>]`,  `<image id>` or `<image@digest>`) - filter images created before given id or references
-* since (`<image-name>[:<tag>]`,  `<image id>` or `<image@digest>`) - filter images created since given id or references
-* reference (pattern of an image reference) - filter images whose reference matches the specified pattern
-
-#### Show untagged images (dangling)
-
-```bash
-$ docker images --filter "dangling=true"
-
-REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
-<none>              <none>              8abc22fbb042        4 weeks ago         0 B

-```
-
-This will display untagged images that are the leaves of the images tree (not
-intermediary layers). These images occur when a new build of an image takes the
-`repo:tag` away from the image ID, leaving it as `<none>:<none>` or untagged.
-A warning will be issued if trying to remove an image when a container is presently
-using it. By having this flag it allows for batch cleanup.
-
-You can use this in conjunction with `docker rmi ...`:
-
-```bash
-$ docker rmi $(docker images -f "dangling=true" -q)
-
-8abc22fbb042
-48e5f45168b9
-bf747efa0e2f
-980fe10e5736
-dea752e4e117
-511136ea3c5a
-```
-
-> **Note**: Docker warns you if any containers exist that are using these
-> untagged images.
-
-
-#### Show images with a given label
-
-The `label` filter matches images based on the presence of a `label` alone or a `label` and a
-value.
-
-The following filter matches images with the `com.example.version` label regardless of its value.
-
-```bash
-$ docker images --filter "label=com.example.version"
-
-REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
-match-me-1          latest              eeae25ada2aa        About a minute ago   188.3 MB
-match-me-2          latest              dea752e4e117        About a minute ago   188.3 MB
-```
-
-The following filter matches images with the `com.example.version` label with the `1.0` value.
-
-```bash
-$ docker images --filter "label=com.example.version=1.0"
-
-REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
-match-me            latest              511136ea3c5a        About a minute ago   188.3 MB
-```
-
-In this example, with the `0.1` value, it returns an empty set because no matches were found.
-
-```bash
-$ docker images --filter "label=com.example.version=0.1"
-REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
-```
-
-#### Filter images by time
-
-The `before` filter shows only images created before the image with
-given id or reference. For example, having these images:
-
-```bash
-$ docker images
-
-REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
-image1              latest              eeae25ada2aa        4 minutes ago        188.3 MB
-image2              latest              dea752e4e117        9 minutes ago        188.3 MB
-image3              latest              511136ea3c5a        25 minutes ago       188.3 MB
-```
-
-Filtering with `before` would give:
-
-```bash
-$ docker images --filter "before=image1"
-
-REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
-image2              latest              dea752e4e117        9 minutes ago        188.3 MB
-image3              latest              511136ea3c5a        25 minutes ago       188.3 MB
-```
-
-Filtering with `since` would give:
-
-```bash
-$ docker images --filter "since=image3"
-REPOSITORY          TAG                 IMAGE ID            CREATED              SIZE
-image1              latest              eeae25ada2aa        4 minutes ago        188.3 MB
-image2              latest              dea752e4e117        9 minutes ago        188.3 MB
-```
-
-#### Filter images by reference
-
-The `reference` filter shows only images whose reference matches
-the specified pattern.
-
-```bash
-$ docker images
-
-REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
-busybox             latest              e02e811dd08f        5 weeks ago         1.09 MB
-busybox             uclibc              e02e811dd08f        5 weeks ago         1.09 MB
-busybox             musl                733eb3059dce        5 weeks ago         1.21 MB
-busybox             glibc               21c16b6787c6        5 weeks ago         4.19 MB
-```
-
-Filtering with `reference` would give:
-
-```bash
-$ docker images --filter=reference='busy*:*libc'
-
-REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
-busybox             uclibc              e02e811dd08f        5 weeks ago         1.09 MB

-```
-
-### Format the output
-
-The formatting option (`--format`) will pretty print container output
-using a Go template.
-
-Valid placeholders for the Go template are listed below:

-| Placeholder | Description|
-| ---- | ---- |
-| `.ID` | Image ID |
-| `.Repository` | Image repository |
-| `.Tag` | Image tag |
-| `.Digest` | Image digest |
-| `.CreatedSince` | Elapsed time since the image was created |
-| `.CreatedAt` | Time when the image was created |
-| `.Size` | Image disk size |
-
-When using the `--format` option, the `image` command will either
-output the data exactly as the template declares or, when using the
-`table` directive, will include column headers as well.
-
-The following example uses a template without headers and outputs the
-`ID` and `Repository` entries separated by a colon for all images:
-
-```bash
-$ docker images --format "{{.ID}}: {{.Repository}}"
-
-77af4d6b9913: <none>
-b6fa739cedf5: committ
-78a85c484f71: <none>
-30557a29d5ab: docker
-5ed6274db6ce: <none>
-746b819f315e: postgres
-746b819f315e: postgres
-746b819f315e: postgres
-746b819f315e: postgres
-```
-
-To list all images with their repository and tag in a table format you
-can use:
-
-```bash
-$ docker images --format "table {{.ID}}\t{{.Repository}}\t{{.Tag}}"
-
-IMAGE ID            REPOSITORY                TAG
-77af4d6b9913        <none>                    <none>
-b6fa739cedf5        committ                   latest
-78a85c484f71        <none>                    <none>
-30557a29d5ab        docker                    latest
-5ed6274db6ce        <none>                    <none>
-746b819f315e        postgres                  9
-746b819f315e        postgres                  9.3
-746b819f315e        postgres                  9.3.5

-# import
-
-```markdown
-Usage:  docker import [OPTIONS] file|URL|- [REPOSITORY[:TAG]]
-
-Import the contents from a tarball to create a filesystem image
-
-Options:
-  -c, --change value     Apply Dockerfile instruction to the created image (default [])
-      --help             Print usage
-  -m, --message string   Set commit message for imported image
-```
-
-## Description
-
-You can specify a `URL` or `-` (dash) to take data directly from `STDIN`. The
-`URL` can point to an archive (.tar, .tar.gz, .tgz, .bzip, .tar.xz, or .txz)
-containing a filesystem or to an individual file on the Docker host.  If you
-specify an archive, Docker untars it in the container relative to the `/`
-(root). If you specify an individual file, you must specify the full path within
-the host. To import from a remote location, specify a `URI` that begins with the
-`http://` or `https://` protocol.
-
-The `--change` option will apply `Dockerfile` instructions to the image
-that is created.
-Supported `Dockerfile` instructions:
-`CMD`|`ENTRYPOINT`|`ENV`|`EXPOSE`|`ONBUILD`|`USER`|`VOLUME`|`WORKDIR`
-
-## Examples
-
-### Import from a remote location
-
-This will create a new untagged image.
-
-```bash
-$ docker import http://example.com/exampleimage.tgz
-```
-
-### Import from a local file
-
-- Import to docker via pipe and `STDIN`.
-
-  ```bash
-  $ cat exampleimage.tgz | docker import - exampleimagelocal:new
-  ```
-
-- Import with a commit message.
-
-  ```bash
-  $ cat exampleimage.tgz | docker import --message "New image imported from tarball" - exampleimagelocal:new
-  ```
-
-- Import to docker from a local archive.
-
-  ```bash
-    $ docker import /path/to/exampleimage.tgz
-  ```
-
-### Import from a local directory
-
-```bash
-$ sudo tar -c . | docker import - exampleimagedir
-```
-
-### Import from a local directory with new configurations
-
-```bash
-$ sudo tar -c . | docker import --change "ENV DEBUG true" - exampleimagedir
-```
-
-Note the `sudo` in this example – you must preserve
-the ownership of the files (especially root ownership) during the
-archiving with tar. If you are not root (or the sudo command) when you
-tar, then the ownerships might not get preserved.

-# The Docker commands
-
-This section contains reference information on using Docker's command line
-client. Each command has a reference page along with samples. If you are
-unfamiliar with the command line, you should start by reading about how to [Use
-the Docker command line](cli.md).
-
-You start the Docker daemon with the command line. How you start the daemon
-affects your Docker containers. For that reason you should also make sure to
-read the [`dockerd`](dockerd.md) reference page.

-
-## Description
-
-This command displays system wide information regarding the Docker installation.
-Information displayed includes the kernel version, number of containers and images.
-The number of images shown is the number of unique images. The same image tagged
-under different names is counted only once.
-
-If a format is specified, the given template will be executed instead of the
-default format. Go's [text/template](http://golang.org/pkg/text/template/) package
-describes all the details of the format.
-
-Depending on the storage driver in use, additional information can be shown, such
-as pool name, data file, metadata file, data space used, total data space, metadata
-space used, and total metadata space.
-
-The data file is where the images are stored and the metadata file is where the
-meta data regarding those images are stored. When run for the first time Docker
-allocates a certain amount of data space and meta data space from the space
-available on the volume where `/var/lib/docker` is mounted.
-
-## Examples
-
-### Show output
-
-The example below shows the output for a daemon running on Red Hat Enterprise Linux,
-using the `devicemapper` storage driver. As can be seen in the output, additional
-information about the `devicemapper` storage driver is shown:

-# inspect
-
-```markdown
-Usage:  docker inspect [OPTIONS] NAME|ID [NAME|ID...]
-
-Return low-level information on Docker object(s) (e.g. container, image, volume,
-network, node, service, or task) identified by name or ID
-
-Options:
-  -f, --format       Format the output using the given Go template
-      --help         Print usage
-  -s, --size         Display total file sizes if the type is container
-      --type         Return JSON for specified type
-```
-
-## Description
-
-Docker inspect provides detailed information on constructs controlled by Docker.
-
-By default, `docker inspect` will render results in a JSON array.
-
-## Request a custom response format (--format)
-
-If a format is specified, the given template will be executed for each result.
-
-Go's [text/template](http://golang.org/pkg/text/template/) package
-describes all the details of the format.
-
-## Specify target type (--type)
-
-`--type container|image|node|network|secret|service|volume|task|plugin`
-
-The `docker inspect` command matches any type of object by either ID or name.
-In some cases multiple type of objects (for example, a container and a volume)
-exist with the same name, making the result ambigious.
-
-To restrict `docker inspect` to a specific type of object, use the `--type`
-option.
-
-The following example inspects a _volume_ named "myvolume"
-
-```bash
-$ docker inspect --type=volume myvolume
-```
-
-## Examples
-
-### Get an instance's IP address
-
-For the most part, you can pick out any field from the JSON in a fairly
-straightforward manner.
-
-```bash
-$ docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $INSTANCE_ID
-```
-
-### Get an instance's MAC address
-
-```bash
-$ docker inspect --format='{{range .NetworkSettings.Networks}}{{.MacAddress}}{{end}}' $INSTANCE_ID
-```
-
-### Get an instance's log path
-
-```bash
-$ docker inspect --format='{{.LogPath}}' $INSTANCE_ID
-```
-
-### Get an instance's image name
-
-```bash
-$ docker inspect --format='{{.Config.Image}}' $INSTANCE_ID
-```
-
-### List all port bindings
-
-You can loop over arrays and maps in the results to produce simple text
-output:
-
-```bash
-$ docker inspect --format='{{range $p, $conf := .NetworkSettings.Ports}} {{$p}} -> {{(index $conf 0).HostPort}} {{end}}' $INSTANCE_ID
-```
-
-### Find a specific port mapping
-
-The `.Field` syntax doesn't work when the field name begins with a
-number, but the template language's `index` function does. The
-`.NetworkSettings.Ports` section contains a map of the internal port
-mappings to a list of external address/port objects. To grab just the
-numeric public port, you use `index` to find the specific port map, and
-then `index` 0 contains the first object inside of that. Then we ask for
-the `HostPort` field to get the public address.
-
-```bash
-$ docker inspect --format='{{(index (index .NetworkSettings.Ports "8787/tcp") 0).HostPort}}' $INSTANCE_ID
-```
-
-### Get a subsection in JSON format
-
-If you request a field which is itself a structure containing other
-fields, by default you get a Go-style dump of the inner values.
-Docker adds a template function, `json`, which can be applied to get
-results in JSON format.
-
-```bash
-$ docker inspect --format='{{json .Config}}' $INSTANCE_ID
-```

-  -p, --password string   Password
-  -u, --username string   Username
-```
-
-## Description
-
-Login to a registry.
-
-### Login to a self-hosted registry
-
-If you want to login to a self-hosted registry you can specify this by
-adding the server name.
-
-```bash
-$ docker login localhost:8080
-```
-
-### Privileged user requirement
-
-`docker login` requires user to use `sudo` or be `root`, except when:
-
-1.  connecting to a remote daemon, such as a `docker-machine` provisioned `docker engine`.
-2.  user is added to the `docker` group.  This will impact the security of your system; the `docker` group is `root` equivalent.  See [Docker Daemon Attack Surface](https://docs.docker.com/security/security/#docker-daemon-attack-surface) for details.
-
-You can log into any public or private repository for which you have
-credentials.  When you log in, the command stores encoded credentials in
-`$HOME/.docker/config.json` on Linux or `%USERPROFILE%/.docker/config.json` on Windows.
-
-### Credentials store
-
-The Docker Engine can keep user credentials in an external credentials store,
-such as the native keychain of the operating system. Using an external store
-is more secure than storing credentials in the Docker configuration file.
-
-To use a credentials store, you need an external helper program to interact
-with a specific keychain or external store. Docker requires the helper
-program to be in the client's host `$PATH`.
-
-This is the list of currently available credentials helpers and where
-you can download them from:
-
-- D-Bus Secret Service: https://github.com/docker/docker-credential-helpers/releases
-- Apple macOS keychain: https://github.com/docker/docker-credential-helpers/releases
-- Microsoft Windows Credential Manager: https://github.com/docker/docker-credential-helpers/releases
-
-You need to specify the credentials store in `$HOME/.docker/config.json`
-to tell the docker engine to use it. The value of the config property should be
-the suffix of the program to use (i.e. everything after `docker-credential-`).
-For example, to use `docker-credential-osxkeychain`:
-
-```json
-{
-	"credsStore": "osxkeychain"
-}
-```
-
-If you are currently logged in, run `docker logout` to remove
-the credentials from the file and run `docker login` again.
-
-### Credential helper protocol
-
-Credential helpers can be any program or script that follows a very simple protocol.
-This protocol is heavily inspired by Git, but it differs in the information shared.
-
-The helpers always use the first argument in the command to identify the action.
-There are only three possible values for that argument: `store`, `get`, and `erase`.
-
-The `store` command takes a JSON payload from the standard input. That payload carries
-the server address, to identify the credential, the user name, and either a password
-or an identity token.
-
-```json
-{
-	"ServerURL": "https://index.docker.io/v1",
-	"Username": "david",
-	"Secret": "passw0rd1"
-}
-```
-
-If the secret being stored is an identity token, the Username should be set to
-`<token>`.
-
-The `store` command can write error messages to `STDOUT` that the docker engine
-will show if there was an issue.
-
-The `get` command takes a string payload from the standard input. That payload carries
-the server address that the docker engine needs credentials for. This is
-an example of that payload: `https://index.docker.io/v1`.
-
-The `get` command writes a JSON payload to `STDOUT`. Docker reads the user name
-and password from this payload:
-
-```json
-{
-	"Username": "david",
-	"Secret": "passw0rd1"
-}
-```
-
-The `erase` command takes a string payload from `STDIN`. That payload carries
-the server address that the docker engine wants to remove credentials for. This is
-an example of that payload: `https://index.docker.io/v1`.
-
-The `erase` command can write error messages to `STDOUT` that the docker engine
-will show if there was an issue.
-
-### Credential helpers
-
-Credential helpers are similar to the credential store above, but act as the
-designated programs to handle credentials for *specific registries*. The default
-credential store (`credsStore` or the config file itself) will not be used for
-operations concerning credentials of the specified registries.
-
-### Logging out
-
-If you are currently logged in, run `docker logout` to remove
-the credentials from the default store.
-
-Credential helpers are specified in a similar way to `credsStore`, but
-allow for multiple helpers to be configured at a time. Keys specify the
-registry domain, and values specify the suffix of the program to use
-(i.e. everything after `docker-credential-`).
-For example:
-
-```json
-{
-  "credHelpers": {
-    "registry.example.com": "registryhelper",
-    "awesomereg.example.org": "hip-star",
-    "unicorn.example.io": "vcbait"
-  }
-}
-```

-  -t, --timestamps     Show timestamps
-```
-
-## Description
-
-The `docker logs` command batch-retrieves logs present at the time of execution.
-
-> **Note**: this command is only functional for containers that are started with
-> the `json-file` or `journald` logging driver.
-
-For more information about selecting and configuring logging drivers, refer to
-[Configure logging drivers](https://docs.docker.com/engine/admin/logging/overview/).
-
-The `docker logs --follow` command will continue streaming the new output from
-the container's `STDOUT` and `STDERR`.
-
-Passing a negative number or a non-integer to `--tail` is invalid and the
-value is set to `all` in that case.
-
-The `docker logs --timestamps` command will add an [RFC3339Nano timestamp](https://golang.org/pkg/time/#pkg-constants)
-, for example `2014-09-16T06:17:46.000000000Z`, to each
-log entry. To ensure that the timestamps are aligned the
-nano-second part of the timestamp will be padded with zero when necessary.
-
-The `docker logs --details` command will add on extra attributes, such as
-environment variables and labels, provided to `--log-opt` when creating the
-container.
-
-The `--since` option shows only the container logs generated after
-a given date. You can specify the date as an RFC 3339 date, a UNIX
-timestamp, or a Go duration string (e.g. `1m30s`, `3h`). Besides RFC3339 date
-format you may also use RFC3339Nano, `2006-01-02T15:04:05`,
-`2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
-timezone on the client will be used if you do not provide either a `Z` or a
-`+-00:00` timezone offset at the end of the timestamp. When providing Unix

-      --link-local-ip value   Add a link-local address for the container (default [])
-```
-
-## Description
-
-Connects a container to a network. You can connect a container by name
-or by ID. Once connected, the container can communicate with other containers in
-the same network.
-
-## Examples
-
-### Connect a running container to a network
-
-```bash
-$ docker network connect multi-host-network container1
-```
-
-### Connect a container to a network when it starts
-
-You can also use the `docker run --network=<network-name>` option to start a container and immediately connect it to a network.
-
-```bash
-$ docker run -itd --network=multi-host-network busybox
-```
-
-### Specify the IP address a container will use on a given network
-
-You can specify the IP address you want to be assigned to the container's interface.
-
-```bash
-$ docker network connect --ip 10.10.36.122 multi-host-network container2
-```
-
-### Use the legacy `--link` option
-
-You can use `--link` option to link another container with a preferred alias
-
-```bash
-$ docker network connect --link container1:c1 multi-host-network container2
-```
-
-### Create a network alias for a container
-
-`--alias` option can be used to resolve the container by another name in the network
-being connected to.
-
-```bash
-$ docker network connect --alias db --alias mysql multi-host-network container2
-```
-
-### Network implications of stopping, pausing, or restarting containers
-
-You can pause, restart, and stop containers that are connected to a network.
-A container connects to its configured networks when it runs.
-
-If specified, the container's IP address(es) is reapplied when a stopped
-container is restarted. If the IP address is no longer available, the container
-fails to start. One way to guarantee that the IP address is available is
-to specify an `--ip-range` when creating the network, and choose the static IP
-address(es) from outside that range. This ensures that the IP address is not
-given to another container while this container is not on the network.
-
-```bash
-$ docker network create --subnet 172.20.0.0/16 --ip-range 172.20.240.0/20 multi-host-network
-```
-
-```bash
-$ docker network connect --ip 172.20.128.2 multi-host-network container2
-```
-
-To verify the container is connected, use the `docker network inspect` command. Use `docker network disconnect` to remove a container from the network.
-
-Once connected in network, containers can communicate using only another
-container's IP address or name. For `overlay` networks or custom plugins that
-support multi-host connectivity, containers connected to the same multi-host
-network but launched from different Engines can also communicate in this way.
-
-You can connect a container to one or more networks. The networks need not be the same type. For example, you can connect a single container bridge and overlay networks.

-## Description
-
-Creates a new network. The `DRIVER` accepts `bridge` or `overlay` which are the
-built-in network drivers. If you have installed a third party or your own custom
-network driver you can specify that `DRIVER` here also. If you don't specify the
-`--driver` option, the command automatically creates a `bridge` network for you.
-When you install Docker Engine it creates a `bridge` network automatically. This
-network corresponds to the `docker0` bridge that Engine has traditionally relied
-on. When you launch a new container with  `docker run` it automatically connects to
-this bridge network. You cannot remove this default bridge network, but you can
-create new ones using the `network create` command.
-
-```bash
-$ docker network create -d bridge my-bridge-network
-```
-
-Bridge networks are isolated networks on a single Engine installation. If you
-want to create a network that spans multiple Docker hosts each running an
-Engine, you must create an `overlay` network. Unlike `bridge` networks, overlay
-networks require some pre-existing conditions before you can create one. These
-conditions are:
-
-* Access to a key-value store. Engine supports Consul, Etcd, and ZooKeeper (Distributed store) key-value stores.
-* A cluster of hosts with connectivity to the key-value store.
-* A properly configured Engine `daemon` on each host in the cluster.
-
-The `dockerd` options that support the `overlay` network are:
-
-* `--cluster-store`
-* `--cluster-store-opt`
-* `--cluster-advertise`
-
-To read more about these options and how to configure them, see ["*Get started
-with multi-host network*"](https://docs.docker.com/engine/userguide/networking/get-started-overlay).
-
-While not required, it is a good idea to install Docker Swarm to
-manage the cluster that makes up your network. Swarm provides sophisticated
-discovery and server management tools that can assist your implementation.
-
-Once you have prepared the `overlay` network prerequisites you simply choose a
-Docker host in the cluster and issue the following to create the network:
-
-```bash
-$ docker network create -d overlay my-multihost-network
-```
-
-Network names must be unique. The Docker daemon attempts to identify naming
-conflicts but this is not guaranteed. It is the user's responsibility to avoid
-name conflicts.
-
-## Examples
-
-### Connect containers
-
-When you start a container, use the `--network` flag to connect it to a network.
-This example adds the `busybox` container to the `mynet` network:
-
-```bash
-$ docker run -itd --network=mynet busybox
-```
-
-If you want to add a container to a network after the container is already
-running, use the `docker network connect` subcommand.
-
-You can connect multiple containers to the same network. Once connected, the
-containers can communicate using only another container's IP address or name.
-For `overlay` networks or custom plugins that support multi-host connectivity,
-containers connected to the same multi-host network but launched from different
-Engines can also communicate in this way.
-
-You can disconnect a container from a network using the `docker network
-disconnect` command.
-
-### Specify advanced options
-
-When you create a network, Engine creates a non-overlapping subnetwork for the
-network by default. This subnetwork is not a subdivision of an existing
-network. It is purely for ip-addressing purposes. You can override this default
-and specify subnetwork values directly using the `--subnet` option. On a
-`bridge` network you can only create a single subnet:
-
-```bash
-$ docker network create --driver=bridge --subnet=192.168.0.0/16 br0
-```
-
-Additionally, you also specify the `--gateway` `--ip-range` and `--aux-address`
-options.
-
-```bash
-$ docker network create \
-  --driver=bridge \
-  --subnet=172.28.0.0/16 \
-  --ip-range=172.28.5.0/24 \
-  --gateway=172.28.5.254 \
-  br0
-```
-
-If you omit the `--gateway` flag the Engine selects one for you from inside a
-preferred pool. For `overlay` networks and for network driver plugins that
-support it you can create multiple subnetworks.
-
-```bash
-$ docker network create -d overlay \
-  --subnet=192.168.0.0/16 \
-  --subnet=192.170.0.0/16 \
-  --gateway=192.168.0.100 \
-  --gateway=192.170.0.100 \
-  --ip-range=192.168.1.0/24 \
-  --aux-address="my-router=192.168.1.5" --aux-address="my-switch=192.168.1.6" \
-  --aux-address="my-printer=192.170.1.5" --aux-address="my-nas=192.170.1.6" \
-  my-multihost-network
-```
-
-Be sure that your subnetworks do not overlap. If they do, the network create
-fails and Engine returns an error.
-
-### Bridge driver options
-
-When creating a custom network, the default network driver (i.e. `bridge`) has
-additional options that can be passed. The following are those options and the
-equivalent docker daemon flags used for docker0 bridge:
-
-| Option                                           | Equivalent  | Description                                           |
-|--------------------------------------------------|-------------|-------------------------------------------------------|
-| `com.docker.network.bridge.name`                 | -           | bridge name to be used when creating the Linux bridge |
-| `com.docker.network.bridge.enable_ip_masquerade` | `--ip-masq` | Enable IP masquerading                                |
-| `com.docker.network.bridge.enable_icc`           | `--icc`     | Enable or Disable Inter Container Connectivity        |
-| `com.docker.network.bridge.host_binding_ipv4`    | `--ip`      | Default IP when binding container ports               |
-| `com.docker.network.driver.mtu`                  | `--mtu`     | Set the containers network MTU                        |
-
-The following arguments can be passed to `docker network create` for any
-network driver, again with their approximate equivalents to `docker daemon`.
-
-| Argument     | Equivalent     | Description                                |
-|--------------|----------------|--------------------------------------------|
-| `--gateway`  | -              | IPv4 or IPv6 Gateway for the master subnet |
-| `--ip-range` | `--fixed-cidr` | Allocate IPs from a range                  |
-| `--internal` | -              | Restrict external access to the network   |
-| `--ipv6`     | `--ipv6`       | Enable IPv6 networking                     |
-| `--subnet`   | `--bip`        | Subnet for network                         |
-
-For example, let's use `-o` or `--opt` options to specify an IP address binding
-when publishing ports:
-
-```bash
-$ docker network create \
-    -o "com.docker.network.bridge.host_binding_ipv4"="172.19.0.1" \
-    simple-network
-```
-
-### Network internal mode
-
-By default, when you connect a container to an `overlay` network, Docker also
-connects a bridge network to it to provide external connectivity. If you want
-to create an externally isolated `overlay` network, you can specify the
-`--internal` option.
-
-### Network ingress mode
-
-You can create the network which will be used to provide the routing-mesh in the
-swarm cluster. You do so by specifying `--ingress` when creating the network. Only
-one ingress network can be created at the time. The network can be removed only
-if no services depend on it. Any option available when creating a overlay network
-is also available when creating the ingress network, besides the `--attachable` option.
-
-```bash
-$ docker network create -d overlay \
-  --subnet=10.11.0.0/16 \
-  --ingress \
-  --opt com.docker.network.mtu=9216 \
-  --opt encrypted=true \
-  my-ingress-network
-```

-
-The `network inspect` command shows the containers, by id, in its
-results. For networks backed by multi-host network driver, such as Overlay,
-this command also shows the container endpoints in other hosts in the
-cluster. These endpoints are represented as "ep-{endpoint-id}" in the output.
-However, for swarm mode networks, only the endpoints that are local to the
-node are shown.
-
-You can specify an alternate format to execute a given
-template for each result. Go's
-[text/template](http://golang.org/pkg/text/template/) package describes all the
-details of the format.

-### Inspect the `ingress` network
-
-For swarm mode overlay networks `network inspect` also shows the IP address and node name
-of the peers. Peers are the nodes in the swarm cluster which have at least one task attached
-to the network. Node name is of the format `<hostname>-<unique ID>`.

-
-### Using `verbose` option for `network inspect`
-
-`docker network inspect --verbose` for swarm mode overlay networks shows service-specific
-details such as the service's VIP and port mappings. It also shows IPs of service tasks,
-and the IPs of the nodes where the tasks are running.
-
-Following is an example output for a overlay network `ov1` that has one service `s1`
-attached to. service `s1` in this case has three replicas.
-
-```bash
-$ docker network inspect --verbose ov1

-# docker network ls
-
-```markdown
-Usage:  docker network ls [OPTIONS]
-
-List networks
-
-Aliases:
-  ls, list
-
-Options:
-  -f, --filter filter   Provide filter values (e.g. 'driver=bridge')
-      --format string   Pretty-print networks using a Go template
-      --help            Print usage

-  -q, --quiet           Only display network IDs
-```
-
-## Description
-
-Lists all the networks the Engine `daemon` knows about. This includes the
-networks that span across multiple hosts in a cluster.
-
-## Examples
-
-### List all networks
-
-```bash
-$ sudo docker network ls
-NETWORK ID          NAME                DRIVER          SCOPE
-7fca4eb8c647        bridge              bridge          local
-9f904ee27bf5        none                null            local
-cf03ee007fb4        host                host            local
-78b03ee04fc4        multi-host          overlay         swarm
-```
-
-Use the `--no-trunc` option to display the full network id:
-
-```bash
-$ docker network ls --no-trunc
-NETWORK ID                                                         NAME                DRIVER           SCOPE
-18a2866682b85619a026c81b98a5e375bd33e1b0936a26cc497c283d27bae9b3   none                null             local

-7b369448dccbf865d397c8d2be0cda7cf7edc6b0945f77d2529912ae917a0185   bridge              bridge           local
-95e74588f40db048e86320c6526440c504650a1ff3e9f7d60a497c4d2163e5bd   foo                 bridge           local
-63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161   dev                 bridge           local
-```
-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there
-is more than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`).
-Multiple filter flags are combined as an `OR` filter. For example,
-`-f type=custom -f type=builtin` returns both `custom` and `builtin` networks.
-
-The currently supported filters are:
-
-* driver
-* id (network's id)
-* label (`label=<key>` or `label=<key>=<value>`)
-* name (network's name)
-* scope (`swarm|global|local`)
-* type (`custom|builtin`)
-
-#### Driver
-
-The `driver` filter matches networks based on their driver.
-
-The following example matches networks with the `bridge` driver:
-
-```bash
-$ docker network ls --filter driver=bridge
-NETWORK ID          NAME                DRIVER            SCOPE
-db9db329f835        test1               bridge            local
-f6e212da9dfd        test2               bridge            local
-```
-
-#### ID
-
-The `id` filter matches on all or part of a network's ID.
-
-The following filter matches all networks with an ID containing the
-`63d1ff1f77b0...` string.
-
-```bash
-$ docker network ls --filter id=63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161
-NETWORK ID          NAME                DRIVER           SCOPE
-63d1ff1f77b0        dev                 bridge           local
-```
-
-You can also filter for a substring in an ID as this shows:
-
-```bash
-$ docker network ls --filter id=95e74588f40d
-NETWORK ID          NAME                DRIVER          SCOPE
-95e74588f40d        foo                 bridge          local
-
-$ docker network ls --filter id=95e
-NETWORK ID          NAME                DRIVER          SCOPE
-95e74588f40d        foo                 bridge          local
-```
-
-#### Label
-
-The `label` filter matches networks based on the presence of a `label` alone or a `label` and a
-value.
-
-The following filter matches networks with the `usage` label regardless of its value.
-
-```bash
-$ docker network ls -f "label=usage"
-NETWORK ID          NAME                DRIVER         SCOPE
-db9db329f835        test1               bridge         local
-f6e212da9dfd        test2               bridge         local
-```
-
-The following filter matches networks with the `usage` label with the `prod` value.
-
-```bash
-$ docker network ls -f "label=usage=prod"
-NETWORK ID          NAME                DRIVER        SCOPE
-f6e212da9dfd        test2               bridge        local
-```
-
-#### Name
-
-The `name` filter matches on all or part of a network's name.
-
-The following filter matches all networks with a name containing the `foobar` string.
-
-```bash
-$ docker network ls --filter name=foobar
-NETWORK ID          NAME                DRIVER       SCOPE
-06e7eef0a170        foobar              bridge       local
-```
-
-You can also filter for a substring in a name as this shows:
-
-```bash
-$ docker network ls --filter name=foo
-NETWORK ID          NAME                DRIVER       SCOPE
-95e74588f40d        foo                 bridge       local
-06e7eef0a170        foobar              bridge       local
-```
-
-#### Scope
-
-The `scope` filter matches networks based on their scope.
-
-The following example matches networks with the `swarm` scope:
-
-```bash
-$ docker network ls --filter scope=swarm
-NETWORK ID          NAME                DRIVER              SCOPE
-xbtm0v4f1lfh        ingress             overlay             swarm
-ic6r88twuu92        swarmnet            overlay             swarm
-```
-
-The following example matches networks with the `local` scope:
-
-```bash
-$ docker network ls --filter scope=local
-NETWORK ID          NAME                DRIVER              SCOPE
-e85227439ac7        bridge              bridge              local
-0ca0e19443ed        host                host                local

-```
-
-#### Type
-
-The `type` filter supports two values; `builtin` displays predefined networks
-(`bridge`, `none`, `host`), whereas `custom` displays user defined networks.
-
-The following filter matches all user defined networks:
-
-```bash
-$ docker network ls --filter type=custom
-NETWORK ID          NAME                DRIVER       SCOPE
-95e74588f40d        foo                 bridge       local  
-63d1ff1f77b0        dev                 bridge       local
-```
-
-By having this flag it allows for batch cleanup. For example, use this filter
-to delete all user defined networks:
-
-```bash
-$ docker network rm `docker network ls --filter type=custom -q`
-```
-
-A warning will be issued when trying to remove a network that has containers
-attached.
-
-### Formatting
-
-The formatting options (`--format`) pretty-prints networks output
-using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-Placeholder  | Description
--------------|------------------------------------------------------------------------------------------
-`.ID`        | Network ID
-`.Name`      | Network name
-`.Driver`    | Network driver
-`.Scope`     | Network scope (local, global)
-`.IPv6`      | Whether IPv6 is enabled on the network or not.
-`.Internal`  | Whether the network is internal or not.
-`.Labels`    | All labels assigned to the network.
-`.Label`     | Value of a specific label for this network. For example `{{.Label "project.version"}}`
-`.CreatedAt` | Time when the network was created
-
-When using the `--format` option, the `network ls` command will either
-output the data exactly as the template declares or, when using the
-`table` directive, includes column headers as well.
-
-The following example uses a template without headers and outputs the
-`ID` and `Driver` entries separated by a colon for all networks:
-
-```bash
-$ docker network ls --format "{{.ID}}: {{.Driver}}"
-afaaab448eb2: bridge
-d1584f8dc718: host
-391df270dc66: null
-```

-# network prune
-
-```markdown
-Usage:	docker network prune [OPTIONS]
-
-Remove all unused networks
-
-Options:
-      --filter filter   Provide filter values (e.g. 'until=<timestamp>')
-  -f, --force           Do not prompt for confirmation
-      --help            Print usage
-```
-
-## Description
-
-Remove all unused networks. Unused networks are those which are not referenced
-by any containers.
-
-## Examples
-
-```bash
-$ docker network prune
-
-WARNING! This will remove all networks not used by at least one container.
-Are you sure you want to continue? [y/N] y
-Deleted Networks:
-n1
-n2
-```
-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
-than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
-
-The currently supported filters are:
-
-* until (`<timestamp>`) - only remove networks created before given timestamp
-* label (`label=<key>`, `label=<key>=<value>`, `label!=<key>`, or `label!=<key>=<value>`) - only remove networks with (or without, in case `label!=...` is used) the specified labels.
-
-The `until` filter can be Unix timestamps, date formatted
-timestamps, or Go duration strings (e.g. `10m`, `1h30m`) computed
-relative to the daemon machine’s time. Supported formats for date
-formatted time stamps include RFC3339Nano, RFC3339, `2006-01-02T15:04:05`,
-`2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
-timezone on the daemon will be used if you do not provide either a `Z` or a
-`+-00:00` timezone offset at the end of the timestamp.  When providing Unix
-timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
-that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
-seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
-fraction of a second no more than nine digits long.
-
-The `label` filter accepts two formats. One is the `label=...` (`label=<key>` or `label=<key>=<value>`),
-which removes networks with the specified labels. The other
-format is the `label!=...` (`label!=<key>` or `label!=<key>=<value>`), which removes
-networks without the specified labels.
-
-The following removes networks created more than 5 minutes ago. Note that
-system networks such as `bridge`, `host`, and `none` will never be pruned:
-
-```none
-$ docker network ls
-
-NETWORK ID          NAME                DRIVER              SCOPE

-# network rm
-
-```markdown
-Usage:  docker network rm NETWORK [NETWORK...]
-
-Remove one or more networks
-
-Aliases:
-  rm, remove
-
-Options:
-      --help   Print usage
-```
-
-## Description
-
-Removes one or more networks by name or identifier. To remove a network,
-you must first disconnect any containers connected to it.
-
-## Examples
-
-### Remove a network
-
-To remove the network named 'my-network':
-
-```bash
-  $ docker network rm my-network
-```
-
-### Remove multiple networks
-
-To delete multiple networks in a single `docker network rm` command, provide
-multiple network names or ids. The following example deletes a network with id
-`3695c422697f` and a network named `my-network`:
-
-```bash
-  $ docker network rm 3695c422697f my-network
-```
-
-When you specify multiple networks, the command attempts to delete each in turn.
-If the deletion of one network fails, the command continues to the next on the
-list and tries to delete that. The command reports success or failure for each
-deletion.

-# node ls
-
-```markdown
-Usage:  docker node ls [OPTIONS]
-
-List nodes in the swarm
-
-Aliases:
-  ls, list
-
-Options:
-  -f, --filter filter   Filter output based on conditions provided
-      --format string   Pretty-print nodes using a Go template
-      --help            Print usage
-  -q, --quiet           Only display IDs
-```
-
-## Description
-
-Lists all the nodes that the Docker Swarm manager knows about. You can filter
-using the `-f` or `--filter` flag. Refer to the [filtering](#filtering) section
-for more information about available filter options.
-
-## Examples
-
-```bash
-$ docker node ls
-
-ID                           HOSTNAME        STATUS  AVAILABILITY  MANAGER STATUS
-1bcef6utixb0l0ca7gxuivsj0    swarm-worker2   Ready   Active
-38ciaotwjuritcdtn9npbnkuz    swarm-worker1   Ready   Active
-e216jshn25ckzbvmwlnh5jr3g *  swarm-manager1  Ready   Active        Leader
-```
-> **Note**:
-> In the above example output, there is a hidden column of `.Self` that indicates if the
-> node is the same node as the current docker daemon. A `*` (e.g., `e216jshn25ckzbvmwlnh5jr3g *`)
-> means this node is the current docker daemon.
-
-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
-than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
-
-The currently supported filters are:
-
-* [id](node_ls.md#id)
-* [label](node_ls.md#label)
-* [membership](node_ls.md#membership)
-* [name](node_ls.md#name)
-* [role](node_ls.md#role)
-
-#### id
-
-The `id` filter matches all or part of a node's id.
-
-```bash
-$ docker node ls -f id=1
-
-ID                         HOSTNAME       STATUS  AVAILABILITY  MANAGER STATUS
-1bcef6utixb0l0ca7gxuivsj0  swarm-worker2  Ready   Active
-```
-
-#### label
-
-The `label` filter matches nodes based on engine labels and on the presence of a `label` alone or a `label` and a value. Node labels are currently not used for filtering.
-
-The following filter matches nodes with the `foo` label regardless of its value.
-
-```bash
-$ docker node ls -f "label=foo"
-
-ID                         HOSTNAME       STATUS  AVAILABILITY  MANAGER STATUS
-1bcef6utixb0l0ca7gxuivsj0  swarm-worker2  Ready   Active
-```
-
-#### membership
-
-The `membership` filter matches nodes based on the presence of a `membership` and a value
-`accepted` or `pending`.
-
-The following filter matches nodes with the `membership` of `accepted`.
-
-```bash
-$ docker node ls -f "membership=accepted"
-
-ID                           HOSTNAME        STATUS  AVAILABILITY  MANAGER STATUS
-1bcef6utixb0l0ca7gxuivsj0    swarm-worker2   Ready   Active
-38ciaotwjuritcdtn9npbnkuz    swarm-worker1   Ready   Active
-```
-
-#### name
-
-The `name` filter matches on all or part of a node hostname.
-
-The following filter matches the nodes with a name equal to `swarm-master` string.
-
-```bash
-$ docker node ls -f name=swarm-manager1
-
-ID                           HOSTNAME        STATUS  AVAILABILITY  MANAGER STATUS
-e216jshn25ckzbvmwlnh5jr3g *  swarm-manager1  Ready   Active        Leader
-```
-
-#### role
-
-The `role` filter matches nodes based on the presence of a `role` and a value `worker` or `manager`.
-
-The following filter matches nodes with the `manager` role.
-
-```bash
-$ docker node ls -f "role=manager"
-
-ID                           HOSTNAME        STATUS  AVAILABILITY  MANAGER STATUS
-e216jshn25ckzbvmwlnh5jr3g *  swarm-manager1  Ready   Active        Leader
-```
-
-### Formatting
-
-The formatting options (`--format`) pretty-prints nodes output
-using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-Placeholder      | Description
------------------|------------------------------------------------------------------------------------------
-`.ID`            | Node ID
-`.Self`          | Node of the daemon (`true/false`, `true`indicates that the node is the same as current docker daemon)
-`.Hostname`      | Node hostname
-`.Status`        | Node status
-`.Availability`  | Node availability ("active", "pause", or "drain")
-`.ManagerStatus` | Manager status of the node
-`.TLSStatus`     | TLS status of the node ("Ready", or "Needs Rotation" has TLS certificate signed by an old CA)
-
-When using the `--format` option, the `node ls` command will either
-output the data exactly as the template declares or, when using the
-`table` directive, includes column headers as well.
-
-The following example uses a template without headers and outputs the
-`ID`, `Hostname`, and `TLS Status` entries separated by a colon for all nodes:
-
-```bash
-$ docker node ls --format "{{.ID}}: {{.Hostname}} {{.TLSStatus}}"
-e216jshn25ckzbvmwlnh5jr3g: swarm-manager1 Ready
-35o6tiywb700jesrt3dmllaza: swarm-worker1 Needs Rotation

-
-Aliases:

-
-Options:
-  -f, --force   Force remove a node from the swarm
-      --help    Print usage
-```
-
-## Description
-
-When run from a manager node, removes the specified nodes from a swarm.
-
-
-## Examples
-
-### Remove a stopped node from the swarm
-
-```bash
-$ docker node rm swarm-node-02
-
-Node swarm-node-02 removed from swarm
-```
-### Attempt to remove a running node from a swarm
-
-Removes the specified nodes from the swarm, but only if the nodes are in the
-down state. If you attempt to remove an active node you will receive an error:
-
-```non
-$ docker node rm swarm-node-03
-
-Error response from daemon: rpc error: code = 9 desc = node swarm-node-03 is not
-down and can't be removed
-```
-
-### Forcibly remove an inaccessible node from a swarm
-
-If you lose access to a worker node or need to shut it down because it has been
-compromised or is not behaving as expected, you can use the `--force` option.
-This may cause transient errors or interruptions, depending on the type of task
-being run on the node.
-
-```bash
-$ docker node rm --force swarm-node-03
-
-Node swarm-node-03 removed from swarm
-```
-
-A manager node must be demoted to a worker node (using `docker node demote`)
-before you can remove it from the swarm.

-
-```markdown
-Usage:  docker node update [OPTIONS] NODE
-
-Update a node

-      --help                  Print usage
-      --label-add value       Add or update a node label (key=value) (default [])
-      --label-rm value        Remove a node label if exists (default [])
-      --role string           Role of the node ("worker"|"manager")
-```
-
-## Description
-
-Update metadata about a node, such as its availability, labels, or roles.
-
-## Examples
-
-### Add label metadata to a node
-
-Add metadata to a swarm node using node labels. You can specify a node label as
-a key with an empty value:
-
-``` bash
-$ docker node update --label-add foo worker1
-```
-
-To add multiple labels to a node, pass the `--label-add` flag for each label:
-
-```bash
-$ docker node update --label-add foo --label-add bar worker1
-```
-
-When you [create a service](service_create.md),
-you can use node labels as a constraint. A constraint limits the nodes where the
-scheduler deploys tasks for a service.
-
-For example, to add a `type` label to identify nodes where the scheduler should
-deploy message queue service tasks:
-
-``` bash
-$ docker node update --label-add type=queue worker1
-```
-
-The labels you set for nodes using `docker node update` apply only to the node
-entity within the swarm. Do not confuse them with the docker daemon labels for
-[dockerd](https://docs.docker.com/engine/userguide/labels-custom-metadata/#daemon-labels).
-
-For more information about labels, refer to [apply custom
-metadata](https://docs.docker.com/engine/userguide/labels-custom-metadata/).

-
-```markdown
-Usage:  docker pause CONTAINER [CONTAINER...]
-
-Pause all processes within one or more containers
-
-Options:

-```
-
-## Description
-
-The `docker pause` command suspends all processes in the specified containers.
-On Linux, this uses the cgroups freezer. Traditionally, when suspending a process
-the `SIGSTOP` signal is used, which is observable by the process being suspended.
-With the cgroups freezer the process is unaware, and unable to capture,
-that it is being suspended, and subsequently resumed. On Windows, only Hyper-V
-containers can be paused.
-
-See the
-[cgroups freezer documentation](https://www.kernel.org/doc/Documentation/cgroup-v1/freezer-subsystem.txt)
-for further details.

-      --disable                 Do not enable the plugin on install

-
-## Description
-
-Installs and enables a plugin. Docker looks first for the plugin on your Docker
-host. If the plugin does not exist locally, then the plugin is pulled from
-the registry. Note that the minimum required registry version to distribute
-plugins is 2.3.0
-
-## Examples
-
-The following example installs `vieus/sshfs` plugin and [sets](plugin_set.md) its
-`DEBUG` environment variable to `1`. To install, `pull` the plugin from Docker
-Hub and prompt the user to accept the list of privileges that the plugin needs,
-set the plugin's parameters and enable the plugin.
-
-```bash
-$ docker plugin install vieux/sshfs DEBUG=1
-
-Plugin "vieux/sshfs" is requesting the following privileges:
- - network: [host]
- - device: [/dev/fuse]
- - capabilities: [CAP_SYS_ADMIN]
-Do you grant the above permissions? [y/N] y
-vieux/sshfs
-```
-
-After the plugin is installed, it appears in the list of plugins:
-
-```bash
-$ docker plugin ls
-
-ID                  NAME                  TAG                 DESCRIPTION                ENABLED

-# plugin ls
-
-```markdown
-Usage:  docker plugin ls [OPTIONS]
-
-List plugins
-
-Aliases:
-  ls, list
-
-Options:
-  -f, --filter filter   Provide filter values (e.g. 'enabled=true')
-      --format string   Pretty-print plugins using a Go template
-      --help            Print usage
-      --no-trunc        Don't truncate output
-  -q, --quiet           Only display plugin IDs
-```
-
-## Description
-
-Lists all the plugins that are currently installed. You can install plugins
-using the [`docker plugin install`](plugin_install.md) command.
-You can also filter using the `-f` or `--filter` flag.
-Refer to the [filtering](#filtering) section for more information about available filter options.
-
-## Examples
-
-```bash
-$ docker plugin ls
-
-ID                  NAME                             TAG                 DESCRIPTION                ENABLED
-69553ca1d123        tiborvass/sample-volume-plugin   latest              A test plugin for Docker   true
-```
-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
-than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
-
-The currently supported filters are:
-
-* enabled (boolean - true or false, 0 or 1)
-* capability (string - currently `volumedriver`, `networkdriver`, `ipamdriver`, `logdriver`, `metricscollector`, or `authz`)
-
-#### enabled
-
-The `enabled` filter matches on plugins enabled or disabled.
-
-#### capability
-
-The `capability` filter matches on plugin capabilities. One plugin
-might have multiple capabilities. Currently `volumedriver`, `networkdriver`,
-`ipamdriver`, `logdriver`, `metricscollector`, and `authz` are supported capabilities.
-
-```bash
-$ docker plugin install --disable tiborvass/no-remove
-
-tiborvass/no-remove
-
-$ docker plugin ls --filter enabled=true
-
-NAME                  TAG                 DESCRIPTION                ENABLED
-```
-
-### Formatting
-
-The formatting options (`--format`) pretty-prints plugins output
-using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-Placeholder    | Description
----------------|------------------------------------------------------------------------------------------
-`.ID`              | Plugin ID
-`.Name`            | Plugin name
-`.Description`     | Plugin description
-`.Enabled`         | Whether plugin is enabled or not
-`.PluginReference` | The reference used to push/pull from a registry
-
-When using the `--format` option, the `plugin ls` command will either
-output the data exactly as the template declares or, when using the
-`table` directive, includes column headers as well.
-
-The following example uses a template without headers and outputs the
-`ID` and `Name` entries separated by a colon for all plugins:
-
-```bash
-$ docker plugin ls --format "{{.ID}}: {{.Name}}"
-
-4be01827a72e: tiborvass/no-remove
-```

-# plugin rm
-
-```markdown
-Usage:  docker plugin rm [OPTIONS] PLUGIN [PLUGIN...]
-
-Remove one or more plugins
-
-Aliases:
-  rm, remove
-
-Options:
-      -f, --force  Force the removal of an active plugin
-          --help   Print usage
-```
-
-## Description
-
-Removes a plugin. You cannot remove a plugin if it is enabled, you must disable
-a plugin using the [`docker plugin disable`](plugin_disable.md) before removing
-it (or use --force, use of force is not recommended, since it can affect
-functioning of running containers using the plugin).
-
-## Examples
-
-The following example disables and removes the `sample-volume-plugin:latest`
-plugin:
-
-```bash
-$ docker plugin disable tiborvass/sample-volume-plugin
-
-tiborvass/sample-volume-plugin
-
-$ docker plugin rm tiborvass/sample-volume-plugin:latest
-
-tiborvass/sample-volume-plugin
-```

-# plugin set
-
-```markdown
-Usage:  docker plugin set PLUGIN KEY=VALUE [KEY=VALUE...]
-
-Change settings for a plugin
-
-Options:
-      --help                    Print usage
-```
-
-## Description
-
-Change settings for a plugin. The plugin must be disabled.
-
-The settings currently supported are:
- * env variables
- * source of mounts
- * path of devices
- * args
-
-## What is settable ?
-
-Look at the plugin manifest, it's easy to see what fields are settable,
-by looking at the `Settable` field.
-
-Here is an extract of a plugin manifest:
-
-```
-{
-        "config": {
-            ...
-            "args": {
-                "name": "myargs",
-                "settable": ["value"],
-                "value": ["foo", "bar"]
-            },
-            "env": [
-                {
-                    "name": "DEBUG",
-                    "settable": ["value"],
-                    "value": "0"
-                },
-                {
-                    "name": "LOGGING",
-                    "value": "1"
-                }
-            ],
-	    "devices": [
-                {
-                    "name": "mydevice",
-                    "path": "/dev/foo",
-                    "settable": ["path"]
-                }
-            ],
-	    "mounts": [
-                {
-                    "destination": "/baz",
-                    "name": "mymount",
-                    "options": ["rbind"],
-                    "settable": ["source"],
-                    "source": "/foo",
-                    "type": "bind"
-                }
-            ],
-	    ...
-	 }
-}
-```
-
-In this example, we can see that the `value` of the `DEBUG` environment variable is settable,
-the `source` of the `mymount` mount is also settable. Same for the `path` of `mydevice` and `value` of `myargs`.
-
-On the contrary, the `LOGGING` environment variable doesn't have any settable field, which implies that user cannot tweak it.
-
-## Examples
-
-### Change an environment variable
-
-The following example change the env variable `DEBUG` on the
-`sample-volume-plugin` plugin.
-
-```bash
-$ docker plugin inspect -f {{.Settings.Env}} tiborvass/sample-volume-plugin
-[DEBUG=0]
-
-$ docker plugin set tiborvass/sample-volume-plugin DEBUG=1
-
-$ docker plugin inspect -f {{.Settings.Env}} tiborvass/sample-volume-plugin
-[DEBUG=1]
-```
-
-### Change the source of a mount
-
-The following example change the source of the `mymount` mount on
-the `myplugin` plugin.
-
-```bash
-$ docker plugin inspect -f '{{with $mount := index .Settings.Mounts 0}}{{$mount.Source}}{{end}}' myplugin
-/foo
-
-$ docker plugins set myplugin mymount.source=/bar
-
-$ docker plugin inspect -f '{{with $mount := index .Settings.Mounts 0}}{{$mount.Source}}{{end}}' myplugin
-/bar
-```
-
-> **Note**: Since only `source` is settable in `mymount`,
-> `docker plugins set mymount=/bar myplugin` would work too.
-
-### Change a device path
-
-The following example change the path of the `mydevice` device on
-the `myplugin` plugin.
-
-```bash
-$ docker plugin inspect -f '{{with $device := index .Settings.Devices 0}}{{$device.Path}}{{end}}' myplugin
-
-/dev/foo
-
-$ docker plugins set myplugin mydevice.path=/dev/bar
-
-$ docker plugin inspect -f '{{with $device := index .Settings.Devices 0}}{{$device.Path}}{{end}}' myplugin
-
-/dev/bar
-```
-
-> **Note**: Since only `path` is settable in `mydevice`,
-> `docker plugins set mydevice=/dev/bar myplugin` would work too.
-
-### Change the source of the arguments
-
-The following example change the value of the args on the `myplugin` plugin.
-
-```bash
-$ docker plugin inspect -f '{{.Settings.Args}}' myplugin
-
-["foo", "bar"]
-
-$ docker plugins set myplugin myargs="foo bar baz"
-
-$ docker plugin inspect -f '{{.Settings.Args}}' myplugin
-
-["foo", "bar", "baz"]
-```

-
-## Examples
-
-### Prevent truncating output
-
-Running `docker ps --no-trunc` showing 2 linked containers.
-
-```bash
-$ docker ps
-
-CONTAINER ID        IMAGE                        COMMAND                CREATED              STATUS              PORTS               NAMES
-4c01db0b339c        ubuntu:12.04                 bash                   17 seconds ago       Up 16 seconds       3300-3310/tcp       webapp
-d7886598dbe2        crosbymichael/redis:latest   /redis-server --dir    33 minutes ago       Up 33 minutes       6379/tcp            redis,webapp/db
-```
-
-### Show both running and stopped containers
-
-The `docker ps` command only shows running containers by default. To see all
-containers, use the `-a` (or `--all`) flag:
-
-```bash
-$ docker ps -a
-```
-
-`docker ps` groups exposed ports into a single range if possible. E.g., a
-container that exposes TCP ports `100, 101, 102` displays `100-102/tcp` in
-the `PORTS` column.
-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there is more
-than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`)
-
-The currently supported filters are:
-
-* id (container's id)
-* label (`label=<key>` or `label=<key>=<value>`)
-* name (container's name)
-* exited (int - the code of exited containers. Only useful with `--all`)
-* status (`created|restarting|running|removing|paused|exited|dead`)
-* ancestor (`<image-name>[:<tag>]`,  `<image id>` or `<image@digest>`) - filters containers that were created from the given image or a descendant.
-* before (container's id or name) - filters containers created before given id or name
-* since (container's id or name) - filters containers created since given id or name
-* isolation (`default|process|hyperv`)   (Windows daemon only)
-* volume (volume name or mount point) - filters containers that mount volumes.
-* network (network id or name) - filters containers connected to the provided network
-* health (starting|healthy|unhealthy|none) - filters containers based on healthcheck status
-* publish=(container's published port) - filters published ports by containers
-* expose=(container's exposed port) - filters exposed ports by containers
-
-#### label
-
-The `label` filter matches containers based on the presence of a `label` alone or a `label` and a
-value.
-
-The following filter matches containers with the `color` label regardless of its value.
-
-```bash
-$ docker ps --filter "label=color"
-
-CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
-673394ef1d4c        busybox             "top"               47 seconds ago      Up 45 seconds                           nostalgic_shockley
-d85756f57265        busybox             "top"               52 seconds ago      Up 51 seconds                           high_albattani
-```
-
-The following filter matches containers with the `color` label with the `blue` value.
-
-```bash
-$ docker ps --filter "label=color=blue"
-
-CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
-d85756f57265        busybox             "top"               About a minute ago   Up About a minute                       high_albattani
-```
-
-#### name
-
-The `name` filter matches on all or part of a container's name.
-
-The following filter matches all containers with a name containing the `nostalgic_stallman` string.
-
-```bash
-$ docker ps --filter "name=nostalgic_stallman"
-
-CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
-9b6247364a03        busybox             "top"               2 minutes ago       Up 2 minutes                            nostalgic_stallman
-```
-
-You can also filter for a substring in a name as this shows:
-
-```bash
-$ docker ps --filter "name=nostalgic"
-
-CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
-715ebfcee040        busybox             "top"               3 seconds ago       Up 1 second                             i_am_nostalgic
-9b6247364a03        busybox             "top"               7 minutes ago       Up 7 minutes                            nostalgic_stallman
-673394ef1d4c        busybox             "top"               38 minutes ago      Up 38 minutes                           nostalgic_shockley
-```
-
-#### exited
-
-The `exited` filter matches containers by exist status code. For example, to
-filter for containers that have exited successfully:
-
-```bash
-$ docker ps -a --filter 'exited=0'
-
-CONTAINER ID        IMAGE             COMMAND                CREATED             STATUS                   PORTS                      NAMES
-ea09c3c82f6e        registry:latest   /srv/run.sh            2 weeks ago         Exited (0) 2 weeks ago   127.0.0.1:5000->5000/tcp   desperate_leakey
-106ea823fe4e        fedora:latest     /bin/sh -c 'bash -l'   2 weeks ago         Exited (0) 2 weeks ago                              determined_albattani
-48ee228c9464        fedora:20         bash                   2 weeks ago         Exited (0) 2 weeks ago                              tender_torvalds
-```
-
-#### Filter by exit signal
-
-You can use a filter to locate containers that exited with status of `137`
-meaning a `SIGKILL(9)` killed them.
-
-```none
-$ docker ps -a --filter 'exited=137'
-
-CONTAINER ID        IMAGE               COMMAND                CREATED             STATUS                       PORTS               NAMES
-b3e1c0ed5bfe        ubuntu:latest       "sleep 1000"           12 seconds ago      Exited (137) 5 seconds ago                       grave_kowalevski
-a2eb5558d669        redis:latest        "/entrypoint.sh redi   2 hours ago         Exited (137) 2 hours ago                         sharp_lalande
-```
-
-Any of these events result in a `137` status:
-
-* the `init` process of the container is killed manually
-* `docker kill` kills the container
-* Docker daemon restarts which kills all running containers
-
-#### status
-
-The `status` filter matches containers by status. You can filter using
-`created`, `restarting`, `running`, `removing`, `paused`, `exited` and `dead`. For example,
-to filter for `running` containers:
-
-```bash
-$ docker ps --filter status=running
-
-CONTAINER ID        IMAGE                  COMMAND             CREATED             STATUS              PORTS               NAMES
-715ebfcee040        busybox                "top"               16 minutes ago      Up 16 minutes                           i_am_nostalgic
-d5c976d3c462        busybox                "top"               23 minutes ago      Up 23 minutes                           top
-9b6247364a03        busybox                "top"               24 minutes ago      Up 24 minutes                           nostalgic_stallman
-```
-
-To filter for `paused` containers:
-
-```bash
-$ docker ps --filter status=paused
-
-CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                      PORTS               NAMES
-673394ef1d4c        busybox             "top"               About an hour ago   Up About an hour (Paused)                       nostalgic_shockley
-```
-
-#### ancestor
-
-The `ancestor` filter matches containers based on its image or a descendant of
-it. The filter supports the following image representation:
-
-- image
-- image:tag
-- image:tag@digest
-- short-id
-- full-id
-
-If you don't specify a `tag`, the `latest` tag is used. For example, to filter
-for containers that use the latest `ubuntu` image:
-
-```bash
-$ docker ps --filter ancestor=ubuntu
-
-CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
-919e1179bdb8        ubuntu-c1           "top"               About a minute ago   Up About a minute                       admiring_lovelace
-5d1e4a540723        ubuntu-c2           "top"               About a minute ago   Up About a minute                       admiring_sammet
-82a598284012        ubuntu              "top"               3 minutes ago        Up 3 minutes                            sleepy_bose
-bab2a34ba363        ubuntu              "top"               3 minutes ago        Up 3 minutes                            focused_yonath
-```
-
-Match containers based on the `ubuntu-c1` image which, in this case, is a child
-of `ubuntu`:
-
-```bash
-$ docker ps --filter ancestor=ubuntu-c1
-
-CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
-919e1179bdb8        ubuntu-c1           "top"               About a minute ago   Up About a minute                       admiring_lovelace
-```
-
-Match containers based on the `ubuntu` version `12.04.5` image:
-
-```bash
-$ docker ps --filter ancestor=ubuntu:12.04.5
-
-CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
-82a598284012        ubuntu:12.04.5      "top"               3 minutes ago        Up 3 minutes                            sleepy_bose
-```
-
-The following matches containers based on the layer `d0e008c6cf02` or an image
-that have this layer in its layer stack.
-
-```bash
-$ docker ps --filter ancestor=d0e008c6cf02
-
-CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
-82a598284012        ubuntu:12.04.5      "top"               3 minutes ago        Up 3 minutes                            sleepy_bose
-```
-
-#### Create time
-
-##### before
-
-The `before` filter shows only containers created before the container with
-given id or name. For example, having these containers created:
-
-```bash
-$ docker ps
-
-CONTAINER ID        IMAGE       COMMAND       CREATED              STATUS              PORTS              NAMES
-9c3527ed70ce        busybox     "top"         14 seconds ago       Up 15 seconds                          desperate_dubinsky
-4aace5031105        busybox     "top"         48 seconds ago       Up 49 seconds                          focused_hamilton
-6e63f6ff38b0        busybox     "top"         About a minute ago   Up About a minute                      distracted_fermat
-```
-
-Filtering with `before` would give:
-
-```bash
-$ docker ps -f before=9c3527ed70ce
-
-CONTAINER ID        IMAGE       COMMAND       CREATED              STATUS              PORTS              NAMES
-4aace5031105        busybox     "top"         About a minute ago   Up About a minute                      focused_hamilton
-6e63f6ff38b0        busybox     "top"         About a minute ago   Up About a minute                      distracted_fermat
-```
-
-##### since
-
-The `since` filter shows only containers created since the container with given
-id or name. For example, with the same containers as in `before` filter:
-
-```bash
-$ docker ps -f since=6e63f6ff38b0
-
-CONTAINER ID        IMAGE       COMMAND       CREATED             STATUS              PORTS               NAMES
-9c3527ed70ce        busybox     "top"         10 minutes ago      Up 10 minutes                           desperate_dubinsky
-4aace5031105        busybox     "top"         10 minutes ago      Up 10 minutes                           focused_hamilton
-```
-
-#### volume
-
-The `volume` filter shows only containers that mount a specific volume or have
-a volume mounted in a specific path:
-
-```bash
-$ docker ps --filter volume=remote-volume --format "table {{.ID}}\t{{.Mounts}}"
-CONTAINER ID        MOUNTS
-9c3527ed70ce        remote-volume
-
-$ docker ps --filter volume=/data --format "table {{.ID}}\t{{.Mounts}}"
-CONTAINER ID        MOUNTS
-9c3527ed70ce        remote-volume
-```
-
-#### network
-
-The `network` filter shows only containers that are connected to a network with
-a given name or id.
-
-The following filter matches all containers that are connected to a network
-with a name containing `net1`.
-
-```bash
-$ docker run -d --net=net1 --name=test1 ubuntu top
-$ docker run -d --net=net2 --name=test2 ubuntu top
-
-$ docker ps --filter network=net1
-
-CONTAINER ID        IMAGE       COMMAND       CREATED             STATUS              PORTS               NAMES
-9d4893ed80fe        ubuntu      "top"         10 minutes ago      Up 10 minutes                           test1
-```
-
-The network filter matches on both the network's name and id. The following
-example shows all containers that are attached to the `net1` network, using
-the network id as a filter;
-
-```bash
-$ docker network inspect --format "{{.ID}}" net1
-
-8c0b4110ae930dbe26b258de9bc34a03f98056ed6f27f991d32919bfe401d7c5
-
-$ docker ps --filter network=8c0b4110ae930dbe26b258de9bc34a03f98056ed6f27f991d32919bfe401d7c5
-
-CONTAINER ID        IMAGE       COMMAND       CREATED             STATUS              PORTS               NAMES
-9d4893ed80fe        ubuntu      "top"         10 minutes ago      Up 10 minutes                           test1
-```
-
-#### publish and expose
-
-The `publish` and `expose` filters show only containers that have published or exposed port with a given port
-number, port range, and/or protocol. The default protocol is `tcp` when not specified.
-
-The following filter matches all containers that have published port of 80:
-
-```bash
-$ docker run -d --publish=80 busybox top
-$ docker run -d --expose=8080 busybox top
-
-$ docker ps -a
-
-CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                   NAMES
-9833437217a5        busybox             "top"               5 seconds ago       Up 4 seconds        8080/tcp                dreamy_mccarthy
-fc7e477723b7        busybox             "top"               50 seconds ago      Up 50 seconds       0.0.0.0:32768->80/tcp   admiring_roentgen
-
-$ docker ps --filter publish=80
-
-CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS                   NAMES
-fc7e477723b7        busybox             "top"               About a minute ago   Up About a minute   0.0.0.0:32768->80/tcp   admiring_roentgen
-```
-
-The following filter matches all containers that have exposed TCP port in the range of `8000-8080`:
-```bash
-$ docker ps --filter expose=8000-8080/tcp
-
-CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
-9833437217a5        busybox             "top"               21 seconds ago      Up 19 seconds       8080/tcp            dreamy_mccarthy
-```
-
-The following filter matches all containers that have exposed UDP port `80`:
-```bash
-$ docker ps --filter publish=80/udp
-
-CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
-```
-
-### Formatting
-
-The formatting option (`--format`) pretty-prints container output using a Go
-template.
-
-Valid placeholders for the Go template are listed below:
-
-Placeholder   | Description
---------------|----------------------------------------------------------------------------------------------------
-`.ID`         | Container ID
-`.Image`      | Image ID
-`.Command`    | Quoted command
-`.CreatedAt`  | Time when the container was created.
-`.RunningFor` | Elapsed time since the container was started.
-`.Ports`      | Exposed ports.
-`.Status`     | Container status.
-`.Size`       | Container disk size.
-`.Names`      | Container names.
-`.Labels`     | All labels assigned to the container.
-`.Label`      | Value of a specific label for this container. For example `'{{.Label "com.docker.swarm.cpu"}}'`
-`.Mounts`     | Names of the volumes mounted in this container.
-`.Networks`   | Names of the networks attached to this container.
-
-When using the `--format` option, the `ps` command will either output the data
-exactly as the template declares or, when using the `table` directive, includes
-column headers as well.
-
-The following example uses a template without headers and outputs the `ID` and
-`Command` entries separated by a colon for all running containers:
-
-```bash
-$ docker ps --format "{{.ID}}: {{.Command}}"
-
-a87ecb4f327c: /bin/sh -c #(nop) MA
-01946d9d34d8: /bin/sh -c #(nop) MA
-c1d3b0166030: /bin/sh -c yum -y up
-41d50ecd2f57: /bin/sh -c #(nop) MA
-```
-
-To list all running containers with their labels in a table format you can use:
-
-```bash
-$ docker ps --format "table {{.ID}}\t{{.Labels}}"
-
-CONTAINER ID        LABELS
-a87ecb4f327c        com.docker.swarm.node=ubuntu,com.docker.swarm.storage=ssd
-01946d9d34d8
-c1d3b0166030        com.docker.swarm.node=debian,com.docker.swarm.cpu=6
-41d50ecd2f57        com.docker.swarm.node=fedora,com.docker.swarm.cpu=3,com.docker.swarm.storage=ssd

-# pull
-
-```markdown
-Usage:  docker pull [OPTIONS] NAME[:TAG|@DIGEST]
-
-Pull an image or a repository from a registry
-
-Options:
-  -a, --all-tags                Download all tagged images in the repository
-      --disable-content-trust   Skip image verification (default true)
-      --help                    Print usage
-```
-
-## Description
-
-Most of your images will be created on top of a base image from the
-[Docker Hub](https://hub.docker.com) registry.
-
-[Docker Hub](https://hub.docker.com) contains many pre-built images that you
-can `pull` and try without needing to define and configure your own.
-
-To download a particular image, or set of images (i.e., a repository),
-use `docker pull`.
-
-### Proxy configuration
-
-If you are behind an HTTP proxy server, for example in corporate settings,
-before open a connect to registry, you may need to configure the Docker
-daemon's proxy settings, using the `HTTP_PROXY`, `HTTPS_PROXY`, and `NO_PROXY`
-environment variables. To set these environment variables on a host using
-`systemd`, refer to the [control and configure Docker with systemd](https://docs.docker.com/engine/admin/systemd/#http-proxy)
-for variables configuration.
-
-### Concurrent downloads
-
-By default the Docker daemon will pull three layers of an image at a time.
-If you are on a low bandwidth connection this may cause timeout issues and you may want to lower
-this via the `--max-concurrent-downloads` daemon option. See the
-[daemon documentation](dockerd.md) for more details.
-
-## Examples
-
-### Pull an image from Docker Hub
-
-To download a particular image, or set of images (i.e., a repository), use
-`docker pull`. If no tag is provided, Docker Engine uses the `:latest` tag as a
-default. This command pulls the `debian:latest` image:
-
-```bash
-$ docker pull debian
-
-Using default tag: latest
-latest: Pulling from library/debian
-fdd5d7827f33: Pull complete
-a3ed95caeb02: Pull complete
-Digest: sha256:e7d38b3517548a1c71e41bffe9c8ae6d6d29546ce46bf62159837aad072c90aa
-Status: Downloaded newer image for debian:latest
-```
-
-Docker images can consist of multiple layers. In the example above, the image
-consists of two layers; `fdd5d7827f33` and `a3ed95caeb02`.
-
-Layers can be reused by images. For example, the `debian:jessie` image shares
-both layers with `debian:latest`. Pulling the `debian:jessie` image therefore
-only pulls its metadata, but not its layers, because all layers are already
-present locally:
-
-```bash
-$ docker pull debian:jessie
-
-jessie: Pulling from library/debian
-fdd5d7827f33: Already exists
-a3ed95caeb02: Already exists
-Digest: sha256:a9c958be96d7d40df920e7041608f2f017af81800ca5ad23e327bc402626b58e
-Status: Downloaded newer image for debian:jessie
-```
-
-To see which images are present locally, use the [`docker images`](images.md)
-command:
-
-```bash
-$ docker images
-
-REPOSITORY   TAG      IMAGE ID        CREATED      SIZE
-debian       jessie   f50f9524513f    5 days ago   125.1 MB
-debian       latest   f50f9524513f    5 days ago   125.1 MB
-```
-
-Docker uses a content-addressable image store, and the image ID is a SHA256
-digest covering the image's configuration and layers. In the example above,
-`debian:jessie` and `debian:latest` have the same image ID because they are
-actually the *same* image tagged with different names. Because they are the
-same image, their layers are stored only once and do not consume extra disk
-space.
-
-For more information about images, layers, and the content-addressable store,
-refer to [understand images, containers, and storage drivers](https://docs.docker.com/engine/userguide/storagedriver/imagesandcontainers/).
-
-
-### Pull an image by digest (immutable identifier)
-
-So far, you've pulled images by their name (and "tag"). Using names and tags is
-a convenient way to work with images. When using tags, you can `docker pull` an
-image again to make sure you have the most up-to-date version of that image.
-For example, `docker pull ubuntu:14.04` pulls the latest version of the Ubuntu
-14.04 image.
-
-In some cases you don't want images to be updated to newer versions, but prefer
-to use a fixed version of an image. Docker enables you to pull an image by its
-*digest*. When pulling an image by digest, you specify *exactly* which version
-of an image to pull. Doing so, allows you to "pin" an image to that version,
-and guarantee that the image you're using is always the same.
-
-To know the digest of an image, pull the image first. Let's pull the latest
-`ubuntu:14.04` image from Docker Hub:
-
-```bash
-$ docker pull ubuntu:14.04
-
-14.04: Pulling from library/ubuntu
-5a132a7e7af1: Pull complete
-fd2731e4c50c: Pull complete
-28a2f68d1120: Pull complete
-a3ed95caeb02: Pull complete
-Digest: sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2
-Status: Downloaded newer image for ubuntu:14.04
-```
-
-Docker prints the digest of the image after the pull has finished. In the example
-above, the digest of the image is:
-
-    sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2
-
-Docker also prints the digest of an image when *pushing* to a registry. This
-may be useful if you want to pin to a version of the image you just pushed.
-
-A digest takes the place of the tag when pulling an image, for example, to
-pull the above image by digest, run the following command:
-
-```bash
-$ docker pull ubuntu@sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2
-
-sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2: Pulling from library/ubuntu
-5a132a7e7af1: Already exists
-fd2731e4c50c: Already exists
-28a2f68d1120: Already exists
-a3ed95caeb02: Already exists
-Digest: sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2
-Status: Downloaded newer image for ubuntu@sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2
-```
-
-Digest can also be used in the `FROM` of a Dockerfile, for example:
-
-```Dockerfile
-FROM ubuntu@sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2
-MAINTAINER some maintainer <maintainer@example.com>
-```
-
-> **Note**: Using this feature "pins" an image to a specific version in time.
-> Docker will therefore not pull updated versions of an image, which may include
-> security updates. If you want to pull an updated image, you need to change the
-> digest accordingly.
-
-
-### Pull from a different registry
-
-By default, `docker pull` pulls images from [Docker Hub](https://hub.docker.com). It is also possible to
-manually specify the path of a registry to pull from. For example, if you have
-set up a local registry, you can specify its path to pull from it. A registry
-path is similar to a URL, but does not contain a protocol specifier (`https://`).
-
-The following command pulls the `testing/test-image` image from a local registry
-listening on port 5000 (`myregistry.local:5000`):
-
-```bash
-$ docker pull myregistry.local:5000/testing/test-image
-```
-
-Registry credentials are managed by [docker login](login.md).
-
-Docker uses the `https://` protocol to communicate with a registry, unless the
-registry is allowed to be accessed over an insecure connection. Refer to the
-[insecure registries](dockerd.md#insecure-registries) section for more information.
-
-
-### Pull a repository with multiple images
-
-By default, `docker pull` pulls a *single* image from the registry. A repository
-can contain multiple images. To pull all images from a repository, provide the
-`-a` (or `--all-tags`) option when using `docker pull`.
-
-This command pulls all images from the `fedora` repository:
-
-```bash
-$ docker pull --all-tags fedora
-
-Pulling repository fedora
-ad57ef8d78d7: Download complete
-105182bb5e8b: Download complete
-511136ea3c5a: Download complete
-73bd853d2ea5: Download complete
-....
-
-Status: Downloaded newer image for fedora
-```
-
-After the pull has completed use the `docker images` command to see the
-images that were pulled. The example below shows all the `fedora` images
-that are present locally:
-
-```bash
-$ docker images fedora
-
-REPOSITORY   TAG         IMAGE ID        CREATED      SIZE
-fedora       rawhide     ad57ef8d78d7    5 days ago   359.3 MB
-fedora       20          105182bb5e8b    5 days ago   372.7 MB
-fedora       heisenbug   105182bb5e8b    5 days ago   372.7 MB
-fedora       latest      105182bb5e8b    5 days ago   372.7 MB
-```
-
-### Cancel a pull
-
-Killing the `docker pull` process, for example by pressing `CTRL-c` while it is
-running in a terminal, will terminate the pull operation.
-
-```bash
-$ docker pull fedora
-
-Using default tag: latest
-latest: Pulling from library/fedora
-a3ed95caeb02: Pulling fs layer
-236608c7b546: Pulling fs layer
-^C
-```
-
-> **Note**: Technically, the Engine terminates a pull operation when the
-> connection between the Docker Engine daemon and the Docker Engine client
-> initiating the pull is lost. If the connection with the Engine daemon is
-> lost for other reasons than a manual interaction, the pull is also aborted.

-# push
-
-```markdown
-Usage:  docker push [OPTIONS] NAME[:TAG]
-
-Push an image or a repository to a registry
-
-Options:
-      --disable-content-trust   Skip image signing (default true)
-      --help                    Print usage
-```
-
-## Description
-
-Use `docker push` to share your images to the [Docker Hub](https://hub.docker.com)
-registry or to a self-hosted one.
-
-Refer to the [`docker tag`](tag.md) reference for more information about valid
-image and tag names.
-
-Killing the `docker push` process, for example by pressing `CTRL-c` while it is
-running in a terminal, terminates the push operation.
-
-Progress bars are shown during docker push, which show the uncompressed size. The 
-actual amount of data that's pushed will be compressed before sending, so the uploaded
- size will not be reflected by the progress bar. 
-
-Registry credentials are managed by [docker login](login.md).
-
-### Concurrent uploads
-
-By default the Docker daemon will push five layers of an image at a time.
-If you are on a low bandwidth connection this may cause timeout issues and you may want to lower
-this via the `--max-concurrent-uploads` daemon option. See the
-[daemon documentation](dockerd.md) for more details.
-
-## Examples
-
-### Push a new image to a registry
-
-First save the new image by finding the container ID (using [`docker ps`](ps.md))
-and then committing it to a new image name.  Note that only `a-z0-9-_.` are
-allowed when naming images:
-
-```bash
-$ docker commit c16378f943fe rhel-httpd
-```
-
-Now, push the image to the registry using the image ID. In this example the
-registry is on host named `registry-host` and listening on port `5000`. To do
-this, tag the image with the host name or IP address, and the port of the
-registry:
-
-```bash
-$ docker tag rhel-httpd registry-host:5000/myadmin/rhel-httpd
-
-$ docker push registry-host:5000/myadmin/rhel-httpd
-```
-
-Check that this worked by running:
-
-```bash
-$ docker images
-```
-
-You should see both `rhel-httpd` and `registry-host:5000/myadmin/rhel-httpd`
-listed.

-  -v, --volumes   Remove the volumes associated with the container
-```
-
-## Examples
-
-### Remove a container
-
-This will remove the container referenced under the link
-`/redis`.
-
-```bash
-$ docker rm /redis
-
-/redis
-```
-
-### Remove a link specified with `--link` on the default bridge network
-
-This will remove the underlying link between `/webapp` and the `/redis`
-containers on the default bridge network, removing all network communication
-between the two containers. This does not apply when `--link` is used with
-user-specified networks.
-
-```bash
-$ docker rm --link /webapp/redis
-
-/webapp/redis
-```
-
-### Force-remove a running container
-
-This command will force-remove a running container.
-
-```bash
-$ docker rm --force redis
-
-redis
-```
-
-The main process inside the container referenced under the link `redis` will receive
-`SIGKILL`, then the container will be removed.
-
-### Remove all stopped containers
-
-```bash
-$ docker rm $(docker ps -a -q)
-```
-
-This command will delete all stopped containers. The command
-`docker ps -a -q` will return all existing container IDs and pass them to
-the `rm` command which will delete them. Any running containers will not be
-deleted.
-
-### Remove a container and its volumes
-
-```bash
-$ docker rm -v redis
-redis
-```
-
-This command will remove the container and any volumes associated with it.
-Note that if a volume was specified with a name, it will not be removed.
-
-### Remove a container and selectively remove volumes
-
-```bash
-$ docker create -v awesome:/foo -v /bar --name hello redis
-hello
-$ docker rm -v hello
-```
-
-In this example, the volume for `/foo` will remain intact, but the volume for
-`/bar` will be removed. The same behavior holds for volumes inherited with
-`--volumes-from`.

-## Description
-
-The `docker run` command first `creates` a writeable container layer over the
-specified image, and then `starts` it using the specified command. That is,
-`docker run` is equivalent to the API `/containers/create` then
-`/containers/(id)/start`. A stopped container can be restarted with all its
-previous changes intact using `docker start`. See `docker ps -a` to view a list
-of all containers.
-
-The `docker run` command can be used in combination with `docker commit` to
-[*change the command that a container runs*](commit.md). There is additional detailed information about `docker run` in the [Docker run reference](../run.md).
-
-For information on connecting a container to a network, see the ["*Docker network overview*"](https://docs.docker.com/engine/userguide/networking/).
-
-## Examples
-
-### Assign name and allocate pseudo-TTY (--name, -it)
-
-```bash
-$ docker run --name test -it debian
-
-root@d6c0fe130dba:/# exit 13
-$ echo $?
-13
-$ docker ps -a | grep test
-d6c0fe130dba        debian:7            "/bin/bash"         26 seconds ago      Exited (13) 17 seconds ago                         test
-```
-
-This example runs a container named `test` using the `debian:latest`
-image. The `-it` instructs Docker to allocate a pseudo-TTY connected to
-the container's stdin; creating an interactive `bash` shell in the container.
-In the example, the `bash` shell is quit by entering
-`exit 13`. This exit code is passed on to the caller of
-`docker run`, and is recorded in the `test` container's metadata.
-
-### Capture container ID (--cidfile)
-
-```bash
-$ docker run --cidfile /tmp/docker_test.cid ubuntu echo "test"
-```
-
-This will create a container and print `test` to the console. The `cidfile`
-flag makes Docker attempt to create a new file and write the container ID to it.
-If the file exists already, Docker will return an error. Docker will close this
-file when `docker run` exits.
-
-### Full container capabilities (--privileged)
-
-```bash
-$ docker run -t -i --rm ubuntu bash
-root@bc338942ef20:/# mount -t tmpfs none /mnt
-mount: permission denied
-```
-
-This will *not* work, because by default, most potentially dangerous kernel
-capabilities are dropped; including `cap_sys_admin` (which is required to mount
-filesystems). However, the `--privileged` flag will allow it to run:
-
-```bash
-$ docker run -t -i --privileged ubuntu bash
-root@50e3f57e16e6:/# mount -t tmpfs none /mnt
-root@50e3f57e16e6:/# df -h
-Filesystem      Size  Used Avail Use% Mounted on
-none            1.9G     0  1.9G   0% /mnt
-```
-
-The `--privileged` flag gives *all* capabilities to the container, and it also
-lifts all the limitations enforced by the `device` cgroup controller. In other
-words, the container can then do almost everything that the host can do. This
-flag exists to allow special use-cases, like running Docker within Docker.
-
-### Set working directory (-w)
-
-```bash
-$ docker  run -w /path/to/dir/ -i -t  ubuntu pwd
-```
-
-The `-w` lets the command being executed inside directory given, here
-`/path/to/dir/`. If the path does not exist it is created inside the container.
-
-### Set storage driver options per container
-
-```bash
-$ docker run -it --storage-opt size=120G fedora /bin/bash
-```
-
-This (size) will allow to set the container rootfs size to 120G at creation time.
-This option is only available for the `devicemapper`, `btrfs`, `overlay2`,
-`windowsfilter` and `zfs` graph drivers.
-For the `devicemapper`, `btrfs`, `windowsfilter` and `zfs` graph drivers,
-user cannot pass a size less than the Default BaseFS Size.
-For the `overlay2` storage driver, the size option is only available if the
-backing fs is `xfs` and mounted with the `pquota` mount option.
-Under these conditions, user can pass any size less then the backing fs size.
-
-### Mount tmpfs (--tmpfs)
-
-```bash
-$ docker run -d --tmpfs /run:rw,noexec,nosuid,size=65536k my_image
-```
-
-The `--tmpfs` flag mounts an empty tmpfs into the container with the `rw`,
-`noexec`, `nosuid`, `size=65536k` options.
-
-### Mount volume (-v, --read-only)
-
-```bash
-$ docker  run  -v `pwd`:`pwd` -w `pwd` -i -t  ubuntu pwd
-```
-
-The `-v` flag mounts the current working directory into the container. The `-w`
-lets the command being executed inside the current working directory, by
-changing into the directory to the value returned by `pwd`. So this
-combination executes the command using the container, but inside the
-current working directory.
-
-```bash
-$ docker run -v /doesnt/exist:/foo -w /foo -i -t ubuntu bash
-```
-
-When the host directory of a bind-mounted volume doesn't exist, Docker
-will automatically create this directory on the host for you. In the
-example above, Docker will create the `/doesnt/exist`
-folder before starting your container.
-
-```bash
-$ docker run --read-only -v /icanwrite busybox touch /icanwrite/here
-```
-
-Volumes can be used in combination with `--read-only` to control where
-a container writes files. The `--read-only` flag mounts the container's root
-filesystem as read only prohibiting writes to locations other than the
-specified volumes for the container.
-
-```bash
-$ docker run -t -i -v /var/run/docker.sock:/var/run/docker.sock -v /path/to/static-docker-binary:/usr/bin/docker busybox sh
-```
-
-By bind-mounting the docker unix socket and statically linked docker
-binary (refer to [get the linux binary](
-https://docs.docker.com/engine/installation/binaries/#/get-the-linux-binary)),
-you give the container the full access to create and manipulate the host's
-Docker daemon.
-
-On Windows, the paths must be specified using Windows-style semantics.
-
-```powershell
-PS C:\> docker run -v c:\foo:c:\dest microsoft/nanoserver cmd /s /c type c:\dest\somefile.txt
-Contents of file
-
-PS C:\> docker run -v c:\foo:d: microsoft/nanoserver cmd /s /c type d:\somefile.txt
-Contents of file
-```
-
-The following examples will fail when using Windows-based containers, as the
-destination of a volume or bind-mount inside the container must be one of:
-a non-existing or empty directory; or a drive other than C:. Further, the source
-of a bind mount must be a local directory, not a file.
-
-```powershell
-net use z: \\remotemachine\share
-docker run -v z:\foo:c:\dest ...
-docker run -v \\uncpath\to\directory:c:\dest ...
-docker run -v c:\foo\somefile.txt:c:\dest ...
-docker run -v c:\foo:c: ...
-docker run -v c:\foo:c:\existing-directory-with-contents ...
-```
-
-For in-depth information about volumes, refer to [manage data in containers](https://docs.docker.com/engine/tutorials/dockervolumes/)
-
-
-### Add bind-mounts or volumes using the --mount flag
-
-The `--mount` flag allows you to mount volumes, host-directories and `tmpfs`
-mounts in a container.
-
-The `--mount` flag supports most options that are supported by the `-v` or the
-`--volume` flag, but uses a different syntax. For in-depth information on the
-`--mount` flag, and a comparison between `--volume` and `--mount`, refer to
-the [service create command reference](service_create.md#add-bind-mounts-or-volumes).
-
-Even though there is no plan to deprecate `--volume`, usage of `--mount` is recommended.
-
-Examples:
-
-```bash
-$ docker run --read-only --mount type=volume,target=/icanwrite busybox touch /icanwrite/here
-```
-
-```bash
-$ docker run -t -i --mount type=bind,src=/data,dst=/data busybox sh
-```
-
-### Publish or expose port (-p, --expose)
-
-```bash
-$ docker run -p 127.0.0.1:80:8080 ubuntu bash
-```
-
-This binds port `8080` of the container to port `80` on `127.0.0.1` of the host
-machine. The [Docker User
-Guide](https://docs.docker.com/engine/userguide/networking/default_network/dockerlinks/)
-explains in detail how to manipulate ports in Docker.
-
-```bash
-$ docker run --expose 80 ubuntu bash
-```
-
-This exposes port `80` of the container without publishing the port to the host
-system's interfaces.
-
-### Set environment variables (-e, --env, --env-file)
-
-```bash
-$ docker run -e MYVAR1 --env MYVAR2=foo --env-file ./env.list ubuntu bash
-```
-
-Use the `-e`, `--env`, and `--env-file` flags to set simple (non-array)
-environment variables in the container you're running, or overwrite variables
-that are defined in the Dockerfile of the image you're running.
-
-You can define the variable and its value when running the container:
-
-```bash
-$ docker run --env VAR1=value1 --env VAR2=value2 ubuntu env | grep VAR
-VAR1=value1
-VAR2=value2
-```
-
-You can also use variables that you've exported to your local environment:
-
-```bash
-export VAR1=value1
-export VAR2=value2
-
-$ docker run --env VAR1 --env VAR2 ubuntu env | grep VAR
-VAR1=value1
-VAR2=value2
-```
-
-When running the command, the Docker CLI client checks the value the variable
-has in your local environment and passes it to the container.
-If no `=` is provided and that variable is not exported in your local
-environment, the variable won't be set in the container.
-
-You can also load the environment variables from a file. This file should use
-the syntax `<variable>=value` (which sets the variable to the given value) or
-`<variable>` (which takes the value from the local environment), and `#` for comments.
-
-```bash
-$ cat env.list
-# This is a comment
-VAR1=value1
-VAR2=value2
-USER
-
-$ docker run --env-file env.list ubuntu env | grep VAR
-VAR1=value1
-VAR2=value2
-USER=denis
-```
-
-### Set metadata on container (-l, --label, --label-file)
-
-A label is a `key=value` pair that applies metadata to a container. To label a container with two labels:
-
-```bash
-$ docker run -l my-label --label com.example.foo=bar ubuntu bash
-```
-
-The `my-label` key doesn't specify a value so the label defaults to an empty
-string(`""`). To add multiple labels, repeat the label flag (`-l` or `--label`).
-
-The `key=value` must be unique to avoid overwriting the label value. If you
-specify labels with identical keys but different values, each subsequent value
-overwrites the previous. Docker uses the last `key=value` you supply.
-
-Use the `--label-file` flag to load multiple labels from a file. Delimit each
-label in the file with an EOL mark. The example below loads labels from a
-labels file in the current directory:
-
-```bash
-$ docker run --label-file ./labels ubuntu bash
-```
-
-The label-file format is similar to the format for loading environment
-variables. (Unlike environment variables, labels are not visible to processes
-running inside a container.) The following example illustrates a label-file
-format:
-
-```none
-com.example.label1="a label"
-
-# this is a comment
-com.example.label2=another\ label
-com.example.label3
-```
-
-You can load multiple label-files by supplying multiple  `--label-file` flags.
-
-For additional information on working with labels, see [*Labels - custom
-metadata in Docker*](https://docs.docker.com/engine/userguide/labels-custom-metadata/) in the Docker User
-Guide.
-
-### Connect a container to a network (--network)
-
-When you start a container use the `--network` flag to connect it to a network.
-This adds the `busybox` container to the `my-net` network.
-
-```bash
-$ docker run -itd --network=my-net busybox
-```
-
-You can also choose the IP addresses for the container with `--ip` and `--ip6`
-flags when you start the container on a user-defined network.
-
-```bash
-$ docker run -itd --network=my-net --ip=10.10.9.75 busybox
-```
-
-If you want to add a running container to a network use the `docker network connect` subcommand.
-
-You can connect multiple containers to the same network. Once connected, the
-containers can communicate easily need only another container's IP address
-or name. For `overlay` networks or custom plugins that support multi-host
-connectivity, containers connected to the same multi-host network but launched
-from different Engines can also communicate in this way.
-
-> **Note**: Service discovery is unavailable on the default bridge network.
-> Containers can communicate via their IP addresses by default. To communicate
-> by name, they must be linked.
-
-You can disconnect a container from a network using the `docker network
-disconnect` command.
-
-### Mount volumes from container (--volumes-from)
-
-```bash
-$ docker run --volumes-from 777f7dc92da7 --volumes-from ba8c0c54f0f2:ro -i -t ubuntu pwd
-```
-
-The `--volumes-from` flag mounts all the defined volumes from the referenced
-containers. Containers can be specified by repetitions of the `--volumes-from`
-argument. The container ID may be optionally suffixed with `:ro` or `:rw` to
-mount the volumes in read-only or read-write mode, respectively. By default,
-the volumes are mounted in the same mode (read write or read only) as
-the reference container.
-
-Labeling systems like SELinux require that proper labels are placed on volume
-content mounted into a container. Without a label, the security system might
-prevent the processes running inside the container from using the content. By
-default, Docker does not change the labels set by the OS.
-
-To change the label in the container context, you can add either of two suffixes
-`:z` or `:Z` to the volume mount. These suffixes tell Docker to relabel file
-objects on the shared volumes. The `z` option tells Docker that two containers
-share the volume content. As a result, Docker labels the content with a shared
-content label. Shared volume labels allow all containers to read/write content.
-The `Z` option tells Docker to label the content with a private unshared label.
-Only the current container can use a private volume.
-
-### Attach to STDIN/STDOUT/STDERR (-a)
-
-The `-a` flag tells `docker run` to bind to the container's `STDIN`, `STDOUT`
-or `STDERR`. This makes it possible to manipulate the output and input as
-needed.
-
-```bash
-$ echo "test" | docker run -i -a stdin ubuntu cat -
-```
-
-This pipes data into a container and prints the container's ID by attaching
-only to the container's `STDIN`.
-
-```bash
-$ docker run -a stderr ubuntu echo test
-```
-
-This isn't going to print anything unless there's an error because we've
-only attached to the `STDERR` of the container. The container's logs
-still store what's been written to `STDERR` and `STDOUT`.
-
-```bash
-$ cat somefile | docker run -i -a stdin mybuilder dobuild
-```
-
-This is how piping a file into a container could be done for a build.
-The container's ID will be printed after the build is done and the build
-logs could be retrieved using `docker logs`. This is
-useful if you need to pipe a file or something else into a container and
-retrieve the container's ID once the container has finished running.
-
-### Add host device to container (--device)
-
-```bash
-$ docker run --device=/dev/sdc:/dev/xvdc \
-             --device=/dev/sdd --device=/dev/zero:/dev/nulo \
-             -i -t \
-             ubuntu ls -l /dev/{xvdc,sdd,nulo}
-
-brw-rw---- 1 root disk 8, 2 Feb  9 16:05 /dev/xvdc
-brw-rw---- 1 root disk 8, 3 Feb  9 16:05 /dev/sdd
-crw-rw-rw- 1 root root 1, 5 Feb  9 16:05 /dev/nulo
-```
-
-It is often necessary to directly expose devices to a container. The `--device`
-option enables that. For example, a specific block storage device or loop
-device or audio device can be added to an otherwise unprivileged container
-(without the `--privileged` flag) and have the application directly access it.
-
-By default, the container will be able to `read`, `write` and `mknod` these devices.
-This can be overridden using a third `:rwm` set of options to each `--device`
-flag:
-
-```bash
-$ docker run --device=/dev/sda:/dev/xvdc --rm -it ubuntu fdisk  /dev/xvdc
-
-Command (m for help): q
-$ docker run --device=/dev/sda:/dev/xvdc:r --rm -it ubuntu fdisk  /dev/xvdc
-You will not be able to write the partition table.
-
-Command (m for help): q
-
-$ docker run --device=/dev/sda:/dev/xvdc:rw --rm -it ubuntu fdisk  /dev/xvdc
-
-Command (m for help): q
-
-$ docker run --device=/dev/sda:/dev/xvdc:m --rm -it ubuntu fdisk  /dev/xvdc
-fdisk: unable to open /dev/xvdc: Operation not permitted
-```
-
-> **Note**: `--device` cannot be safely used with ephemeral devices. Block devices
-> that may be removed should not be added to untrusted containers with
-> `--device`.
-
-### Restart policies (--restart)
-
-Use Docker's `--restart` to specify a container's *restart policy*. A restart
-policy controls whether the Docker daemon restarts a container after exit.
-Docker supports the following restart policies:
-
-| Policy    | Result                                                                                                                                                                                                                                                           |
-|:----------|:-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
-| `no`      | Do not automatically restart the container when it exits. This is the default.                                                                                                                                                                                   |
-| `failure` | Restart only if the container exits with a non-zero exit status. Optionally, limit the number of restart retries the Docker daemon attempts.                                                                                                                     |
-| `always`  | Always restart the container regardless of the exit status. When you specify always, the Docker daemon will try to restart the container indefinitely. The container will also always start on daemon startup, regardless of the current state of the container. |
-
-```bash
-$ docker run --restart=always redis
-```
-
-This will run the `redis` container with a restart policy of **always**
-so that if the container exits, Docker will restart it.
-
-More detailed information on restart policies can be found in the
-[Restart Policies (--restart)](../run.md#restart-policies-restart)
-section of the Docker run reference page.
-
-### Add entries to container hosts file (--add-host)
-
-You can add other hosts into a container's `/etc/hosts` file by using one or
-more `--add-host` flags. This example adds a static address for a host named
-`docker`:
-
-```bash
-$ docker run --add-host=docker:10.180.0.1 --rm -it debian
-
-root@f38c87f2a42d:/# ping docker
-PING docker (10.180.0.1): 48 data bytes
-56 bytes from 10.180.0.1: icmp_seq=0 ttl=254 time=7.600 ms
-56 bytes from 10.180.0.1: icmp_seq=1 ttl=254 time=30.705 ms
-^C--- docker ping statistics ---
-2 packets transmitted, 2 packets received, 0% packet loss
-round-trip min/avg/max/stddev = 7.600/19.152/30.705/11.553 ms
-```
-
-Sometimes you need to connect to the Docker host from within your
-container. To enable this, pass the Docker host's IP address to
-the container using the `--add-host` flag. To find the host's address,
-use the `ip addr show` command.
-
-The flags you pass to `ip addr show` depend on whether you are
-using IPv4 or IPv6 networking in your containers. Use the following
-flags for IPv4 address retrieval for a network device named `eth0`:
-
-```bash
-$ HOSTIP=`ip -4 addr show scope global dev eth0 | grep inet | awk '{print \$2}' | cut -d / -f 1`
-$ docker run  --add-host=docker:${HOSTIP} --rm -it debian
-```
-
-For IPv6 use the `-6` flag instead of the `-4` flag. For other network
-devices, replace `eth0` with the correct device name (for example `docker0`
-for the bridge device).
-
-### Set ulimits in container (--ulimit)
-
-Since setting `ulimit` settings in a container requires extra privileges not
-available in the default container, you can set these using the `--ulimit` flag.
-`--ulimit` is specified with a soft and hard limit as such:
-`<type>=<soft limit>[:<hard limit>]`, for example:
-
-```bash
-$ docker run --ulimit nofile=1024:1024 --rm debian sh -c "ulimit -n"
-1024
-```
-
-> **Note**: If you do not provide a `hard limit`, the `soft limit` will be used
-> for both values. If no `ulimits` are set, they will be inherited from
-> the default `ulimits` set on the daemon.  `as` option is disabled now.
-> In other words, the following script is not supported:
->
-> ```bash
-> $ docker run -it --ulimit as=1024 fedora /bin/bash`
-> ```
-
-The values are sent to the appropriate `syscall` as they are set.
-Docker doesn't perform any byte conversion. Take this into account when setting the values.
-
-#### For `nproc` usage
-
-Be careful setting `nproc` with the `ulimit` flag as `nproc` is designed by Linux to set the
-maximum number of processes available to a user, not to a container.  For example, start four
-containers with `daemon` user:
-
-```bash
-$ docker run -d -u daemon --ulimit nproc=3 busybox top
-
-$ docker run -d -u daemon --ulimit nproc=3 busybox top
-
-$ docker run -d -u daemon --ulimit nproc=3 busybox top
-
-$ docker run -d -u daemon --ulimit nproc=3 busybox top
-```
-
-The 4th container fails and reports "[8] System error: resource temporarily unavailable" error.
-This fails because the caller set `nproc=3` resulting in the first three containers using up
-the three processes quota set for the `daemon` user.
-
-### Stop container with signal (--stop-signal)
-
-The `--stop-signal` flag sets the system call signal that will be sent to the container to exit.
-This signal can be a valid unsigned number that matches a position in the kernel's syscall table, for instance 9,
-or a signal name in the format SIGNAME, for instance SIGKILL.
-
-### Optional security options (--security-opt)
-
-On Windows, this flag can be used to specify the `credentialspec` option.
-The `credentialspec` must be in the format `file://spec.txt` or `registry://keyname`.
-
-### Stop container with timeout (--stop-timeout)
-
-The `--stop-timeout` flag sets the timeout (in seconds) that a pre-defined (see `--stop-signal`) system call
-signal that will be sent to the container to exit. After timeout elapses the container will be killed with SIGKILL.
-
-### Specify isolation technology for container (--isolation)
-
-This option is useful in situations where you are running Docker containers on
-Windows. The `--isolation <value>` option sets a container's isolation technology.
-On Linux, the only supported is the `default` option which uses
-Linux namespaces. These two commands are equivalent on Linux:
-
-```bash
-$ docker run -d busybox top
-$ docker run -d --isolation default busybox top
-```
-
-On Windows, `--isolation` can take one of these values:
-
-
-| Value     | Description                                                                                |
-|:----------|:-------------------------------------------------------------------------------------------|
-| `default` | Use the value specified by the Docker daemon's `--exec-opt` or system default (see below). |
-| `process` | Shared-kernel namespace isolation (not supported on Windows client operating systems).     |
-| `hyperv`  | Hyper-V hypervisor partition-based isolation.                                              |
-
-The default isolation on Windows server operating systems is `process`. The default (and only supported)
-isolation on Windows client operating systems is `hyperv`. An attempt to start a container on a client
-operating system with `--isolation process` will fail.
-
-On Windows server, assuming the default configuration, these commands are equivalent
-and result in `process` isolation:
-
-```PowerShell
-PS C:\> docker run -d microsoft/nanoserver powershell echo process
-PS C:\> docker run -d --isolation default microsoft/nanoserver powershell echo process
-PS C:\> docker run -d --isolation process microsoft/nanoserver powershell echo process
-```
-
-If you have set the `--exec-opt isolation=hyperv` option on the Docker `daemon`, or
-are running against a Windows client-based daemon, these commands are equivalent and
-result in `hyperv` isolation:
-
-```PowerShell
-PS C:\> docker run -d microsoft/nanoserver powershell echo hyperv
-PS C:\> docker run -d --isolation default microsoft/nanoserver powershell echo hyperv
-PS C:\> docker run -d --isolation hyperv microsoft/nanoserver powershell echo hyperv
-```
-
-### Specify hard limits on memory available to containers (-m, --memory)
-
-These parameters always set an upper limit on the memory available to the container. On Linux, this
-is set on the cgroup and applications in a container can query it at `/sys/fs/cgroup/memory/memory.limit_in_bytes`.
-
-On Windows, this will affect containers differently depending on what type of isolation is used.
-
-- With `process` isolation, Windows will report the full memory of the host system, not the limit to applications running inside the container
-    ```powershell
-    docker run -it -m 2GB --isolation=process microsoft/nanoserver powershell Get-ComputerInfo *memory*
-
-    CsTotalPhysicalMemory      : 17064509440
-    CsPhyicallyInstalledMemory : 16777216
-    OsTotalVisibleMemorySize   : 16664560
-    OsFreePhysicalMemory       : 14646720
-    OsTotalVirtualMemorySize   : 19154928
-    OsFreeVirtualMemory        : 17197440
-    OsInUseVirtualMemory       : 1957488
-    OsMaxProcessMemorySize     : 137438953344
-    ```
-- With `hyperv` isolation, Windows will create a utility VM that is big enough to hold the memory limit, plus the minimal OS needed to host the container. That size is reported as "Total Physical Memory."
-    ```powershell
-    docker run -it -m 2GB --isolation=hyperv microsoft/nanoserver powershell Get-ComputerInfo *memory*
-
-    CsTotalPhysicalMemory      : 2683355136
-    CsPhyicallyInstalledMemory :
-    OsTotalVisibleMemorySize   : 2620464
-    OsFreePhysicalMemory       : 2306552
-    OsTotalVirtualMemorySize   : 2620464
-    OsFreeVirtualMemory        : 2356692
-    OsInUseVirtualMemory       : 263772
-    OsMaxProcessMemorySize     : 137438953344
-    ```
-
-
-### Configure namespaced kernel parameters (sysctls) at runtime
-
-The `--sysctl` sets namespaced kernel parameters (sysctls) in the
-container. For example, to turn on IP forwarding in the containers
-network namespace, run this command:
-
-```bash
-$ docker run --sysctl net.ipv4.ip_forward=1 someimage
-```
-
-> **Note**: Not all sysctls are namespaced. Docker does not support changing sysctls
-> inside of a container that also modify the host system. As the kernel
-> evolves we expect to see more sysctls become namespaced.
-
-#### Currently supported sysctls
-
-- `IPC Namespace`:
-
-  ```none
-  kernel.msgmax, kernel.msgmnb, kernel.msgmni, kernel.sem, kernel.shmall, kernel.shmmax, kernel.shmmni, kernel.shm_rmid_forced
-  Sysctls beginning with fs.mqueue.*
-  ```
-
-  If you use the `--ipc=host` option these sysctls will not be allowed.
-
-- `Network Namespace`:
-
-  Sysctls beginning with net.*
-
-  If you use the `--network=host` option using these sysctls will not be allowed.

-### Limit search results (--limit)
-
-The flag `--limit` is the maximum number of results returned by a search. This value could
-be in the range between 1 and 100. The default value of `--limit` is 25.
-
-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there is more
-than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`)
-
-The currently supported filters are:
-
-* stars (int - number of stars the image has)
-* is-automated (true|false) - is the image automated or not
-* is-official (true|false) - is the image official or not
-
-
-#### stars
-
-This example displays images with a name containing 'busybox' and at
-least 3 stars:

-```Markdown
-Usage:  docker secret inspect [OPTIONS] SECRET [SECRET...]
-
-Display detailed information on one or more secrets
-
-Options:
-  -f, --format string   Format the output using the given Go template
-      --help            Print usage
-```
-
-## Description
-
-Inspects the specified secret. This command has to be run targeting a manager
-node.
-
-By default, this renders all results in a JSON array. If a format is specified,
-the given template will be executed for each result.
-
-Go's [text/template](http://golang.org/pkg/text/template/) package
-describes all the details of the format.
-
-For detailed information about using secrets, refer to [manage sensitive data with Docker secrets](https://docs.docker.com/engine/swarm/secrets/).
-
-## Examples
-
-### Inspect a secret by name or ID
-
-You can inspect a secret, either by its *name*, or *ID*
-
-For example, given the following secret:
-
-```bash
-$ docker secret ls
-
-ID                          NAME                CREATED             UPDATED

-
-```none
-$ docker secret inspect secret.json
-
-[
-    {
-        "ID": "eo7jnzguqgtpdah3cm5srfb97",
-        "Version": {
-            "Index": 17
-        },
-        "CreatedAt": "2017-03-24T08:15:09.735271783Z",

-
-## Description
-
-Run this command on a manager node to list the secrets in the swarm.
-
-For detailed information about using secrets, refer to [manage sensitive data with Docker secrets](https://docs.docker.com/engine/swarm/secrets/).
-
-## Examples
-
-```bash
-$ docker secret ls
-
-ID                          NAME                        CREATED             UPDATED

-```
-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there is more
-than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
-
-The currently supported filters are:
-
-* [id](secret_ls.md#id) (secret's ID)
-* [label](secret_ls.md#label) (`label=<key>` or `label=<key>=<value>`)
-* [name](secret_ls.md#name) (secret's name)
-
-#### id
-
-The `id` filter matches all or prefix of a secret's id.
-
-```bash
-$ docker secret ls -f "id=6697bflskwj1998km1gnnjr38"
-
-ID                          NAME                        CREATED             UPDATED
-6697bflskwj1998km1gnnjr38   q5s5570vtvnimefos1fyeo2u2   6 weeks ago         6 weeks ago
-```
-
-#### label
-
-The `label` filter matches secrets based on the presence of a `label` alone or
-a `label` and a value.
-
-The following filter matches all secrets with a `project` label regardless of
-its value:
-
-```bash
-$ docker secret ls --filter label=project
-
-ID                          NAME                        CREATED             UPDATED
-mem02h8n73mybpgqjf0kfi1n0   test_secret                 About an hour ago   About an hour ago
-```
-
-The following filter matches only services with the `project` label with the
-`project-a` value.
-
-```bash
-$ docker service ls --filter label=project=test
-
-ID                          NAME                        CREATED             UPDATED
-mem02h8n73mybpgqjf0kfi1n0   test_secret                 About an hour ago   About an hour ago
-```
-
-#### name
-
-The `name` filter matches on all or prefix of a secret's name.
-
-The following filter matches secret with a name containing a prefix of `test`.
-
-```bash
-$ docker secret ls --filter name=test_secret
-
-ID                          NAME                        CREATED             UPDATED
-mem02h8n73mybpgqjf0kfi1n0   test_secret                 About an hour ago   About an hour ago
-```
-
-### Format the output
-
-The formatting option (`--format`) pretty prints secrets output
-using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-| Placeholder  | Description                                                                          |
-| ------------ | ------------------------------------------------------------------------------------ |
-| `.ID`        | Secret ID                                                                            |
-| `.Name`      | Secret name                                                                          |
-| `.CreatedAt` | Time when the secret was created                                                     |
-| `.UpdatedAt` | Time when the secret was updated                                                     |
-| `.Labels`    | All labels assigned to the secret                                                    |
-| `.Label`     | Value of a specific label for this secret. For example `{{.Label "secret.ssh.key"}}` |
-
-When using the `--format` option, the `secret ls` command will either
-output the data exactly as the template declares or, when using the
-`table` directive, will include column headers as well.
-
-The following example uses a template without headers and outputs the
-`ID` and `Name` entries separated by a colon for all images:
-
-```bash
-$ docker secret ls --format "{{.ID}}: {{.Name}}"
-
-77af4d6b9913: secret-1
-b6fa739cedf5: secret-2
-78a85c484f71: secret-3
-```
-
-To list all secrets with their name and created date in a table format you
-can use:
-
-```bash
-$ docker secret ls --format "table {{.ID}}\t{{.Name}}\t{{.CreatedAt}}"
-
-ID                  NAME                      CREATED
-77af4d6b9913        secret-1                  5 minutes ago
-b6fa739cedf5        secret-2                  3 hours ago
-78a85c484f71        secret-3                  10 days ago
-```

-
-## Description
-
-Creates a service as described by the specified parameters. You must run this
-command on a manager node.
-
-## Examples
-
-### Create a service
-
-```bash
-$ docker service create --name redis redis:3.0.6
-
-dmu1ept4cxcfe8k8lhtux3ro3
-
-$ docker service create --mode global --name redis2 redis:3.0.6
-
-a8q9dasaafudfs8q8w32udass
-
-$ docker service ls
-
-ID            NAME    MODE        REPLICAS  IMAGE
-dmu1ept4cxcf  redis   replicated  1/1       redis:3.0.6
-a8q9dasaafud  redis2  global      1/1       redis:3.0.6
-```
-
-### Create a service with 5 replica tasks (--replicas)
-
-Use the `--replicas` flag to set the number of replica tasks for a replicated
-service. The following command creates a `redis` service with `5` replica tasks:
-
-```bash
-$ docker service create --name redis --replicas=5 redis:3.0.6
-
-4cdgfyky7ozwh3htjfw0d12qv
-```
-
-The above command sets the *desired* number of tasks for the service. Even
-though the command returns immediately, actual scaling of the service may take
-some time. The `REPLICAS` column shows both the *actual* and *desired* number
-of replica tasks for the service.
-
-In the following example the desired state is  `5` replicas, but the current
-number of `RUNNING` tasks is `3`:
-
-```bash
-$ docker service ls
-
-ID            NAME   MODE        REPLICAS  IMAGE
-4cdgfyky7ozw  redis  replicated  3/5       redis:3.0.7
-```
-
-Once all the tasks are created and `RUNNING`, the actual number of tasks is
-equal to the desired number:
-
-```bash
-$ docker service ls
-
-ID            NAME   MODE        REPLICAS  IMAGE
-4cdgfyky7ozw  redis  replicated  5/5       redis:3.0.7
-```
-
-### Create a service with secrets
-
-Use the `--secret` flag to give a container access to a
-[secret](secret_create.md).
-
-Create a service specifying a secret:
-
-```bash
-$ docker service create --name redis --secret secret.json redis:3.0.6
-
-4cdgfyky7ozwh3htjfw0d12qv
-```
-
-Create a service specifying the secret, target, user/group ID and mode:
-
-```bash
-$ docker service create --name redis \
-    --secret source=ssh-key,target=ssh \
-    --secret source=app-key,target=app,uid=1000,gid=1001,mode=0400 \
-    redis:3.0.6
-
-4cdgfyky7ozwh3htjfw0d12qv
-```
-
-Secrets are located in `/run/secrets` in the container.  If no target is
-specified, the name of the secret will be used as the in memory file in the
-container.  If a target is specified, that will be the filename.  In the
-example above, two files will be created: `/run/secrets/ssh` and
-`/run/secrets/app` for each of the secret targets specified.
-
-### Create a service with a rolling update policy
-
-```bash
-$ docker service create \
-  --replicas 10 \
-  --name redis \
-  --update-delay 10s \
-  --update-parallelism 2 \
-  redis:3.0.6
-```
-
-When you run a [service update](service_update.md), the scheduler updates a
-maximum of 2 tasks at a time, with `10s` between updates. For more information,
-refer to the [rolling updates
-tutorial](https://docs.docker.com/engine/swarm/swarm-tutorial/rolling-update/).
-
-### Set environment variables (-e, --env)
-
-This sets environmental variables for all tasks in a service. For example:
-
-```bash
-$ docker service create --name redis_2 --replicas 5 --env MYVAR=foo redis:3.0.6
-```
-
-### Create a service with specific hostname (--hostname)
-
-This option sets the docker service containers hostname to a specific string.
-For example:
-
-```bash
-$ docker service create --name redis --hostname myredis redis:3.0.6
-```
-
-### Set metadata on a service (-l, --label)
-
-A label is a `key=value` pair that applies metadata to a service. To label a
-service with two labels:
-
-```bash
-$ docker service create \
-  --name redis_2 \
-  --label com.example.foo="bar"
-  --label bar=baz \
-  redis:3.0.6
-```
-
-For more information about labels, refer to [apply custom
-metadata](https://docs.docker.com/engine/userguide/labels-custom-metadata/).
-
-### Add bind-mounts or volumes
-
-Docker supports two different kinds of mounts, which allow containers to read to
-or write from files or directories on other containers or the host operating
-system. These types are _data volumes_ (often referred to simply as volumes) and
-_bind-mounts_.
-
-Additionally, Docker supports `tmpfs` mounts.
-
-A **bind-mount** makes a file or directory on the host available to the
-container it is mounted within. A bind-mount may be either read-only or
-read-write. For example, a container might share its host's DNS information by
-means of a bind-mount of the host's `/etc/resolv.conf` or a container might
-write logs to its host's `/var/log/myContainerLogs` directory. If you use
-bind-mounts and your host and containers have different notions of permissions,
-access controls, or other such details, you will run into portability issues.
-
-A **named volume** is a mechanism for decoupling persistent data needed by your
-container from the image used to create the container and from the host machine.
-Named volumes are created and managed by Docker, and a named volume persists
-even when no container is currently using it. Data in named volumes can be
-shared between a container and the host machine, as well as between multiple
-containers. Docker uses a _volume driver_ to create, manage, and mount volumes.
-You can back up or restore volumes using Docker commands.
-
-A **tmpfs** mounts a tmpfs inside a container for volatile data.
-
-Consider a situation where your image starts a lightweight web server. You could
-use that image as a base image, copy in your website's HTML files, and package
-that into another image. Each time your website changed, you'd need to update
-the new image and redeploy all of the containers serving your website. A better
-solution is to store the website in a named volume which is attached to each of
-your web server containers when they start. To update the website, you just
-update the named volume.
-
-For more information about named volumes, see
-[Data Volumes](https://docs.docker.com/engine/tutorials/dockervolumes/).
-
-The following table describes options which apply to both bind-mounts and named
-volumes in a service:

-#### Bind Propagation
-
-Bind propagation refers to whether or not mounts created within a given
-bind-mount or named volume can be propagated to replicas of that mount. Consider
-a mount point `/mnt`, which is also mounted on `/tmp`. The propation settings
-control whether a mount on `/tmp/a` would also be available on `/mnt/a`. Each
-propagation setting has a recursive counterpoint. In the case of recursion,
-consider that `/tmp/a` is also mounted as `/foo`. The propagation settings
-control whether `/mnt/a` and/or `/tmp/a` would exist.
-
-The `bind-propagation` option defaults to `rprivate` for both bind-mounts and
-volume mounts, and is only configurable for bind-mounts. In other words, named
-volumes do not support bind propagation.
-
-- **`shared`**: Sub-mounts of the original mount are exposed to replica mounts,
-                and sub-mounts of replica mounts are also propagated to the
-                original mount.
-- **`slave`**: similar to a shared mount, but only in one direction. If the
-               original mount exposes a sub-mount, the replica mount can see it.
-               However, if the replica mount exposes a sub-mount, the original
-               mount cannot see it.
-- **`private`**: The mount is private. Sub-mounts within it are not exposed to
-                 replica mounts, and sub-mounts of replica mounts are not
-                 exposed to the original mount.
-- **`rshared`**: The same as shared, but the propagation also extends to and from
-                 mount points nested within any of the original or replica mount
-                 points.
-- **`rslave`**: The same as `slave`, but the propagation also extends to and from
-                 mount points nested within any of the original or replica mount
-                 points.
-- **`rprivate`**: The default. The same as `private`, meaning that no mount points
-                  anywhere within the original or replica mount points propagate
-                  in either direction.
-
-For more information about bind propagation, see the
-[Linux kernel documentation for shared subtree](https://www.kernel.org/doc/Documentation/filesystems/sharedsubtree.txt).

-
-#### Differences between "--mount" and "--volume"
-
-The `--mount` flag supports most options that are supported by the `-v`
-or `--volume` flag for `docker run`, with some important exceptions:
-
-- The `--mount` flag allows you to specify a volume driver and volume driver
-  options *per volume*, without creating the volumes in advance. In contrast,
-  `docker run` allows you to specify a single volume driver which is shared
-  by all volumes, using the `--volume-driver` flag.
-
-- The `--mount` flag allows you to specify custom metadata ("labels") for a volume,
-  before the volume is created.
-
-- When you use `--mount` with `type=bind`, the host-path must refer to an *existing*
-  path on the host. The path will not be created for you and the service will fail
-  with an error if the path does not exist.
-
-- The `--mount` flag does not allow you to relabel a volume with `Z` or `z` flags,
-  which are used for `selinux` labeling.
-
-#### Create a service using a named volume
-
-The following example creates a service that uses a named volume:
-
-```bash
-$ docker service create \
-  --name my-service \
-  --replicas 3 \
-  --mount type=volume,source=my-volume,destination=/path/in/container,volume-label="color=red",volume-label="shape=round" \
-  nginx:alpine
-```
-
-For each replica of the service, the engine requests a volume named "my-volume"
-from the default ("local") volume driver where the task is deployed. If the
-volume does not exist, the engine creates a new volume and applies the "color"
-and "shape" labels.
-
-When the task is started, the volume is mounted on `/path/in/container/` inside
-the container.
-
-Be aware that the default ("local") volume is a locally scoped volume driver.
-This means that depending on where a task is deployed, either that task gets a
-*new* volume named "my-volume", or shares the same "my-volume" with other tasks
-of the same service. Multiple containers writing to a single shared volume can
-cause data corruption if the software running inside the container is not
-designed to handle concurrent processes writing to the same location. Also take
-into account that containers can be re-scheduled by the Swarm orchestrator and
-be deployed on a different node.
-
-#### Create a service that uses an anonymous volume
-
-The following command creates a service with three replicas with an anonymous
-volume on `/path/in/container`:
-
-```bash
-$ docker service create \
-  --name my-service \
-  --replicas 3 \
-  --mount type=volume,destination=/path/in/container \
-  nginx:alpine
-```
-
-In this example, no name (`source`) is specified for the volume, so a new volume
-is created for each task. This guarantees that each task gets its own volume,
-and volumes are not shared between tasks. Anonymous volumes are removed after
-the task using them is complete.
-
-#### Create a service that uses a bind-mounted host directory
-
-The following example bind-mounts a host directory at `/path/in/container` in
-the containers backing the service:
-
-```bash
-$ docker service create \
-  --name my-service \
-  --mount type=bind,source=/path/on/host,destination=/path/in/container \
-  nginx:alpine
-```
-
-### Set service mode (--mode)
-
-The service mode determines whether this is a _replicated_ service or a _global_
-service. A replicated service runs as many tasks as specified, while a global
-service runs on each active node in the swarm.
-
-The following command creates a global service:
-
-```bash
-$ docker service create \
- --name redis_2 \
- --mode global \
- redis:3.0.6
-```
-
-### Specify service constraints (--constraint)
-
-You can limit the set of nodes where a task can be scheduled by defining
-constraint expressions. Multiple constraints find nodes that satisfy every
-expression (AND match). Constraints can match node or Docker Engine labels as
-follows:
-
-
-<table>
-  <tr>
-    <th>node attribute</th>
-    <th>matches</th>
-    <th>example</th>
-  </tr>
-  <tr>
-    <td><tt>node.id</tt></td>
-    <td>Node ID</td>
-    <td><tt>node.id == 2ivku8v2gvtg4</tt></td>
-  </tr>
-  <tr>
-    <td><tt>node.hostname</tt></td>
-    <td>Node hostname</td>
-    <td><tt>node.hostname != node-2</tt></td>
-  </tr>
-  <tr>
-    <td><tt>node.role</tt></td>
-    <td>Node role</td>
-    <td><tt>node.role == manager</tt></td>
-  </tr>
-  <tr>
-    <td><tt>node.labels</tt></td>
-    <td>user defined node labels</td>
-    <td><tt>node.labels.security == high</tt></td>
-  </tr>
-  <tr>
-    <td><tt>engine.labels</tt></td>
-    <td>Docker Engine's labels</td>
-    <td><tt>engine.labels.operatingsystem == ubuntu 14.04</tt></td>
-  </tr>
-</table>
-
-
-`engine.labels` apply to Docker Engine labels like operating system,
-drivers, etc. Swarm administrators add `node.labels` for operational purposes by
-using the [`docker node update`](node_update.md) command.
-
-For example, the following limits tasks for the redis service to nodes where the
-node type label equals queue:
-
-```bash
-$ docker service create \
-  --name redis_2 \
-  --constraint 'node.labels.type == queue' \
-  redis:3.0.6
-```
-
-### Specify service placement preferences (--placement-pref)
-
-You can set up the service to divide tasks evenly over different categories of
-nodes. One example of where this can be useful is to balance tasks over a set
-of datacenters or availability zones. The example below illustrates this:
-
-```bash
-$ docker service create \
-  --replicas 9 \
-  --name redis_2 \
-  --placement-pref 'spread=node.labels.datacenter' \
-  redis:3.0.6
-```
-
-This uses `--placement-pref` with a `spread` strategy (currently the only
-supported strategy) to spread tasks evenly over the values of the `datacenter`
-node label. In this example, we assume that every node has a `datacenter` node
-label attached to it. If there are three different values of this label among
-nodes in the swarm, one third of the tasks will be placed on the nodes
-associated with each value. This is true even if there are more nodes with one
-value than another. For example, consider the following set of nodes:
-
-- Three nodes with `node.labels.datacenter=east`
-- Two nodes with `node.labels.datacenter=south`
-- One node with `node.labels.datacenter=west`
-
-Since we are spreading over the values of the `datacenter` label and the
-service has 9 replicas, 3 replicas will end up in each datacenter. There are
-three nodes associated with the value `east`, so each one will get one of the
-three replicas reserved for this value. There are two nodes with the value
-`south`, and the three replicas for this value will be divided between them,
-with one receiving two replicas and another receiving just one. Finally, `west`
-has a single node that will get all three replicas reserved for `west`.
-
-If the nodes in one category (for example, those with
-`node.labels.datacenter=south`) can't handle their fair share of tasks due to
-constraints or resource limitations, the extra tasks will be assigned to other
-nodes instead, if possible.
-
-Both engine labels and node labels are supported by placement preferences. The
-example above uses a node label, because the label is referenced with
-`node.labels.datacenter`. To spread over the values of an engine label, use
-`--placement-pref spread=engine.labels.<labelname>`.
-
-It is possible to add multiple placement preferences to a service. This
-establishes a hierarchy of preferences, so that tasks are first divided over
-one category, and then further divided over additional categories. One example
-of where this may be useful is dividing tasks fairly between datacenters, and
-then splitting the tasks within each datacenter over a choice of racks. To add
-multiple placement preferences, specify the `--placement-pref` flag multiple
-times. The order is significant, and the placement preferences will be applied
-in the order given when making scheduling decisions.
-
-The following example sets up a service with multiple placement preferences.
-Tasks are spread first over the various datacenters, and then over racks
-(as indicated by the respective labels):
-
-```bash
-$ docker service create \
-  --replicas 9 \
-  --name redis_2 \
-  --placement-pref 'spread=node.labels.datacenter' \
-  --placement-pref 'spread=node.labels.rack' \
-  redis:3.0.6
-```
-
-When updating a service with `docker service update`, `--placement-pref-add`
-appends a new placement preference after all existing placement preferences.
-`--placement-pref-rm` removes an existing placement preference that matches the
-argument.
-
-### Attach a service to an existing network (--network)
-
-You can use overlay networks to connect one or more services within the swarm.
-
-First, create an overlay network on a manager node the docker network create
-command:
-
-```bash
-$ docker network create --driver overlay my-network
-
-etjpu59cykrptrgw0z0hk5snf
-```
-
-After you create an overlay network in swarm mode, all manager nodes have
-access to the network.
-
-When you create a service and pass the --network flag to attach the service to
-the overlay network:
-
-```bash
-$ docker service create \
-  --replicas 3 \
-  --network my-network \
-  --name my-web \
-  nginx
-
-716thylsndqma81j6kkkb5aus
-```
-
-The swarm extends my-network to each node running the service.
-
-Containers on the same network can access each other using
-[service discovery](https://docs.docker.com/engine/swarm/networking/#use-swarm-mode-service-discovery).
-
-### Publish service ports externally to the swarm (-p, --publish)
-
-You can publish service ports to make them available externally to the swarm
-using the `--publish` flag:
-
-```bash
-$ docker service create --publish <TARGET-PORT>:<SERVICE-PORT> nginx
-```
-
-For example:
-
-```bash
-$ docker service create --name my_web --replicas 3 --publish 8080:80 nginx
-```
-
-When you publish a service port, the swarm routing mesh makes the service
-accessible at the target port on every node regardless if there is a task for
-the service running on the node. For more information refer to
-[Use swarm mode routing mesh](https://docs.docker.com/engine/swarm/ingress/).
-
-### Publish a port for TCP only or UDP only
-
-By default, when you publish a port, it is a TCP port. You can
-specifically publish a UDP port instead of or in addition to a TCP port. When
-you publish both TCP and UDP ports, Docker 1.12.2 and earlier require you to
-add the suffix `/tcp` for TCP ports. Otherwise it is optional.
-
-#### TCP only
-
-The following two commands are equivalent.
-
-```bash
-$ docker service create --name dns-cache -p 53:53 dns-cache
-
-$ docker service create --name dns-cache -p 53:53/tcp dns-cache
-```
-
-#### TCP and UDP
-
-```bash
-$ docker service create --name dns-cache -p 53:53/tcp -p 53:53/udp dns-cache
-```
-
-#### UDP only
-
-```bash
-$ docker service create --name dns-cache -p 53:53/udp dns-cache
-```
-
-### Create services using templates
-
-You can use templates for some flags of `service create`, using the syntax
-provided by the Go's [text/template](http://golang.org/pkg/text/template/) package.
-
-The supported flags are the following :
-
-- `--hostname`
-- `--mount`
-- `--env`
-
-Valid placeholders for the Go template are listed below:
-
-
-<table>
-  <tr>
-    <th>Placeholder</th>
-    <th>Description</th>
-  </tr>
-  <tr>
-    <td><tt>.Service.ID</tt></td>
-    <td>Service ID</td>
-  </tr>
-  <tr>
-    <td><tt>.Service.Name</tt></td>
-    <td>Service name</td>
-  </tr>
-  <tr>
-    <td><tt>.Service.Labels</tt></td>
-    <td>Service labels</td>
-  </tr>
-  <tr>
-    <td><tt>.Node.ID</tt></td>
-    <td>Node ID</td>
-  </tr>
-  <tr>
-    <td><tt>.Task.ID</tt></td>
-    <td>Task ID</td>
-  </tr>
-  <tr>
-    <td><tt>.Task.Name</tt></td>
-    <td>Task name</td>
-  </tr>
-  <tr>
-    <td><tt>.Task.Slot</tt></td>
-    <td>Task slot</td>
-  </tr>
-</table>
-
-
-#### Template example
-
-In this example, we are going to set the template of the created containers based on the
-service's name and the node's ID where it sits.
-
-```bash
-$ docker service create --name hosttempl \
-                        --hostname="{{.Node.ID}}-{{.Service.Name}}"\
-                         busybox top
-
-va8ew30grofhjoychbr6iot8c
-
-$ docker service ps va8ew30grofhjoychbr6iot8c
-

-
-## Description
-
-Inspects the specified service. This command has to be run targeting a manager
-node.
-
-By default, this renders all results in a JSON array. If a format is specified,
-the given template will be executed for each result.
-
-Go's [text/template](http://golang.org/pkg/text/template/) package
-describes all the details of the format.
-
-## Examples
-
-### Inspect a service by name or ID
-
-You can inspect a service, either by its *name*, or *ID*
-
-For example, given the following service;
-
-```bash
-$ docker service ls
-ID            NAME   MODE        REPLICAS  IMAGE
-dmu1ept4cxcf  redis  replicated  3/3       redis:3.0.6
-```
-
-Both `docker service inspect redis`, and `docker service inspect dmu1ept4cxcf`
-produce the same result:
-
-```none
-$ docker service inspect redis
-
-[
-    {
-        "ID": "dmu1ept4cxcfe8k8lhtux3ro3",
-        "Version": {

-        "Endpoint": {
-            "Spec": {}
-        }
-    }
-]
-```
-
-```bash
-$ docker service inspect dmu1ept4cxcf
-
-[
-    {
-        "ID": "dmu1ept4cxcfe8k8lhtux3ro3",
-        "Version": {
-            "Index": 12
-        },
-        ...
-    }
-]
-```
-
-### Formatting
-
-You can print the inspect output in a human-readable format instead of the default
-JSON output, by using the `--pretty` option:
-
-```bash
-$ docker service inspect --pretty frontend
-
-ID:		c8wgl7q4ndfd52ni6qftkvnnp
-Name:		frontend
-Labels:
- - org.example.projectname=demo-app
-Service Mode:	REPLICATED
- Replicas:		5
-Placement:
-UpdateConfig:
- Parallelism:	0
- On failure:	pause
- Max failure ratio:	0
-ContainerSpec:
- Image:		nginx:alpine
-Resources:
-Networks:	net1
-Endpoint Mode:  vip
-Ports:
- PublishedPort = 4443
-  Protocol = tcp
-  TargetPort = 443
-  PublishMode = ingress
-```
-
-You can also use `--format pretty` for the same effect.
-
-
-#### Find the number of tasks running as part of a service
-
-The `--format` option can be used to obtain specific information about a
-service. For example, the following command outputs the number of replicas
-of the "redis" service.
-
-```bash
-$ docker service inspect --format='{{.Spec.Mode.Replicated.Replicas}}' redis
-
-10
-```

-The `docker service logs` command can be used with either the name or ID of a
-service, or with the ID of a task. If a service is passed, it will display logs
-for all of the containers in that service. If a task is passed, it will only
-display logs from that particular task.
-
-> **Note**: This command is only functional for services that are started with
-> the `json-file` or `journald` logging driver.
-
-For more information about selecting and configuring logging drivers, refer to
-[Configure logging drivers](https://docs.docker.com/engine/admin/logging/overview/).
-
-The `docker service logs --follow` command will continue streaming the new output from
-the service's `STDOUT` and `STDERR`.
-
-Passing a negative number or a non-integer to `--tail` is invalid and the
-value is set to `all` in that case.
-
-The `docker service logs --timestamps` command will add an [RFC3339Nano timestamp](https://golang.org/pkg/time/#pkg-constants)
-, for example `2014-09-16T06:17:46.000000000Z`, to each
-log entry. To ensure that the timestamps are aligned the
-nano-second part of the timestamp will be padded with zero when necessary.
-
-The `docker service logs --details` command will add on extra attributes, such as
-environment variables and labels, provided to `--log-opt` when creating the
-service.
-
-The `--since` option shows only the service logs generated after
-a given date. You can specify the date as an RFC 3339 date, a UNIX
-timestamp, or a Go duration string (e.g. `1m30s`, `3h`). Besides RFC3339 date
-format you may also use RFC3339Nano, `2006-01-02T15:04:05`,
-`2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
-timezone on the client will be used if you do not provide either a `Z` or a
-`+-00:00` timezone offset at the end of the timestamp. When providing Unix
-timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
-that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
-seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
-fraction of a second no more than nine digits long. You can combine the
-`--since` option with either or both of the `--follow` or `--tail` options.

-# service ls
-
-```Markdown
-Usage:	docker service ls [OPTIONS]
-
-List services
-
-Aliases:
-  ls, list
-
-Options:
-  -f, --filter filter   Filter output based on conditions provided
-      --format string   Pretty-print services using a Go template
-      --help            Print usage
-  -q, --quiet           Only display IDs
-```
-
-## Description
-
-This command when run targeting a manager, lists services are running in the
-swarm.
-
-## Examples
-
-On a manager node:
-
-```bash
-$ docker service ls
-
-ID            NAME      MODE        REPLICAS    IMAGE
-c8wgl7q4ndfd  frontend  replicated  5/5         nginx:alpine
-dmu1ept4cxcf  redis     replicated  3/3         redis:3.0.6
-iwe3278osahj  mongo     global      7/7         mongo:3.3
-```
-
-The `REPLICAS` column shows both the *actual* and *desired* number of tasks for
-the service.
-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
-than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
-
-The currently supported filters are:
-
-* [id](service_ls.md#id)
-* [label](service_ls.md#label)
-* [mode](service_ls.md#mode)
-* [name](service_ls.md#name)
-
-#### id
-
-The `id` filter matches all or part of a service's id.
-
-```bash
-$ docker service ls -f "id=0bcjw"
-ID            NAME   MODE        REPLICAS  IMAGE
-0bcjwfh8ychr  redis  replicated  1/1       redis:3.0.6
-```
-
-#### label
-
-The `label` filter matches services based on the presence of a `label` alone or
-a `label` and a value.
-
-The following filter matches all services with a `project` label regardless of
-its value:
-
-```bash
-$ docker service ls --filter label=project
-ID            NAME       MODE        REPLICAS  IMAGE
-01sl1rp6nj5u  frontend2  replicated  1/1       nginx:alpine
-36xvvwwauej0  frontend   replicated  5/5       nginx:alpine
-74nzcxxjv6fq  backend    replicated  3/3       redis:3.0.6
-```
-
-The following filter matches only services with the `project` label with the
-`project-a` value.
-
-```bash
-$ docker service ls --filter label=project=project-a
-ID            NAME      MODE        REPLICAS  IMAGE
-36xvvwwauej0  frontend  replicated  5/5       nginx:alpine
-74nzcxxjv6fq  backend   replicated  3/3       redis:3.0.6
-```
-
-#### mode
-
-The `mode` filter matches on the mode (either `replicated` or `global`) of a service.
-
-The following filter matches only `global` services.
-
-```bash
-$ docker service ls --filter mode=global
-ID                  NAME                MODE                REPLICAS            IMAGE
-w7y0v2yrn620        top                 global              1/1                 busybox
-```
-
-#### name
-
-The `name` filter matches on all or part of a service's name.
-
-The following filter matches services with a name containing `redis`.
-
-```bash
-$ docker service ls --filter name=redis
-ID            NAME   MODE        REPLICAS  IMAGE
-0bcjwfh8ychr  redis  replicated  1/1       redis:3.0.6
-```
-
-### Formatting
-
-The formatting options (`--format`) pretty-prints services output
-using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-Placeholder | Description
-------------|------------------------------------------------------------------------------------------
-`.ID`       | Service ID
-`.Name`     | Service name
-`.Mode`     | Service mode (replicated, global)
-`.Replicas` | Service replicas
-`.Image`    | Service image
-`.Ports`    | Service ports published in ingress mode
-
-When using the `--format` option, the `service ls` command will either
-output the data exactly as the template declares or, when using the
-`table` directive, includes column headers as well.
-
-The following example uses a template without headers and outputs the
-`ID`, `Mode`, and `Replicas` entries separated by a colon for all services:
-
-```bash
-$ docker service ls --format "{{.ID}}: {{.Mode}} {{.Replicas}}"
-
-0zmvwuiu3vue: replicated 10/10
-fm6uf97exkul: global 5/5
-```

-
-## Description
-
-Lists the tasks that are running as part of the specified services. This command
-has to be run targeting a manager node.
-
-## Examples
-
-### List the tasks that are part of a service
-
-The following command shows all the tasks that are part of the `redis` service:
-
-```bash
-$ docker service ps redis
-
-ID             NAME      IMAGE        NODE      DESIRED STATE  CURRENT STATE          ERROR  PORTS

-8eaxrb2fqpbn   redis.10  redis:3.0.5  manager1  Running        Running 8 seconds
-```
-
-In addition to _running_ tasks, the output also shows the task history. For
-example, after updating the service to use the `redis:3.0.6` image, the output
-may look like this:
-
-```bash
-$ docker service ps redis
-
-ID            NAME         IMAGE        NODE      DESIRED STATE  CURRENT STATE                   ERROR  PORTS

-blkttv7zs8ee   \_ redis.4  redis:3.0.5  worker1   Shutdown       Shutdown 11 seconds ago
-```
-
-The number of items in the task history is determined by the
-`--task-history-limit` option that was set when initializing the swarm. You can
-change the task history retention limit using the
-[`docker swarm update`](swarm_update.md) command.
-
-When deploying a service, docker resolves the digest for the service's
-image, and pins the service to that digest. The digest is not shown by
-default, but is printed if `--no-trunc` is used. The `--no-trunc` option
-also shows the non-truncated task ID, and error-messages, as can be seen below;
-
-```bash
-$ docker service ps --no-trunc redis
-
-ID                          NAME         IMAGE                                                                                NODE      DESIRED STATE  CURRENT STATE            ERROR                                                                                           PORTS

-```
-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there
-is more than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`).
-Multiple filter flags are combined as an `OR` filter. For example,
-`-f name=redis.1 -f name=redis.7` returns both `redis.1` and `redis.7` tasks.
-
-The currently supported filters are:
-
-* [id](#id)
-* [name](#name)
-* [node](#node)
-* [desired-state](#desired-state)
-
-
-#### id
-
-The `id` filter matches on all or a prefix of a task's ID.
-
-```bash
-$ docker service ps -f "id=8" redis
-
-ID             NAME      IMAGE        NODE      DESIRED STATE  CURRENT STATE      ERROR  PORTS
-8ryt076polmc   redis.4   redis:3.0.6  worker1   Running        Running 9 seconds
-8eaxrb2fqpbn   redis.10  redis:3.0.6  manager1  Running        Running 8 seconds
-```
-
-#### name
-
-The `name` filter matches on task names.
-
-```bash
-$ docker service ps -f "name=redis.1" redis
-ID            NAME     IMAGE        NODE      DESIRED STATE  CURRENT STATE      ERROR  PORTS
-qihejybwf1x5  redis.1  redis:3.0.6  manager1  Running        Running 8 seconds
-```
-
-
-#### node
-
-The `node` filter matches on a node name or a node ID.
-
-```bash
-$ docker service ps -f "node=manager1" redis
-ID            NAME      IMAGE        NODE      DESIRED STATE  CURRENT STATE      ERROR  PORTS
-0qihejybwf1x  redis.1   redis:3.0.6  manager1  Running        Running 8 seconds
-1x0v8yomsncd  redis.5   redis:3.0.6  manager1  Running        Running 8 seconds
-3w1wu13yupln  redis.9   redis:3.0.6  manager1  Running        Running 8 seconds
-8eaxrb2fqpbn  redis.10  redis:3.0.6  manager1  Running        Running 8 seconds
-```
-
-#### desired-state
-
-The `desired-state` filter can take the values `running`, `shutdown`, or `accepted`.
-
-### Formatting
-
-The formatting options (`--format`) pretty-prints tasks output
-using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-Placeholder     | Description
-----------------|------------------------------------------------------------------------------------------
-`.ID`           | Task ID
-`.Name`         | Task name
-`.Image`        | Task image
-`.Node`         | Node ID
-`.DesiredState` | Desired state of the task (`running`, `shutdown`, or `accepted`)
-`.CurrentState` | Current state of the task
-`.Error`        | Error
-`.Ports`        | Task published ports
-
-When using the `--format` option, the `service ps` command will either
-output the data exactly as the template declares or, when using the
-`table` directive, includes column headers as well.
-
-The following example uses a template without headers and outputs the
-`Name` and `Image` entries separated by a colon for all tasks:
-
-```bash
-$ docker service ps --format "{{.Name}}: {{.Image}}" top
-top.1: busybox
-top.2: busybox
-top.3: busybox

-# service scale
-
-```markdown
-Usage:  docker service scale SERVICE=REPLICAS [SERVICE=REPLICAS...]
-
-Scale one or multiple replicated services
-
-Options:
-      --help   Print usage
-```
-
-## Description
-
-The scale command enables you to scale one or more replicated services either up
-or down to the desired number of replicas. This command cannot be applied on
-services which are global mode. The command will return immediately, but the
-actual scaling of the service may take some time. To stop all replicas of a
-service while keeping the service active in the swarm you can set the scale to 0.
-
-## Examples
-
-### Scale a single service
-
-The following command scales the "frontend" service to 50 tasks.
-
-```bash
-$ docker service scale frontend=50
-
-frontend scaled to 50
-```
-
-The following command tries to scale a global service to 10 tasks and returns an error.
-
-```bash
-$ docker service create --mode global --name backend backend:latest
-
-b4g08uwuairexjub6ome6usqh
-
-$ docker service scale backend=10
-
-backend: scale can only be used with replicated mode
-```
-
-Directly afterwards, run `docker service ls`, to see the actual number of
-replicas.
-
-```bash
-$ docker service ls --filter name=frontend
-
-ID            NAME      MODE        REPLICAS  IMAGE
-3pr5mlvu3fh9  frontend  replicated  15/50     nginx:alpine
-```
-
-You can also scale a service using the [`docker service update`](service_update.md)
-command. The following commands are equivalent:
-
-```bash
-$ docker service scale frontend=50
-$ docker service update --replicas=50 frontend
-```
-
-### Scale multiple services
-
-The `docker service scale` command allows you to set the desired number of
-tasks for multiple services at once. The following example scales both the
-backend and frontend services:
-
-```bash
-$ docker service scale backend=3 frontend=5
-
-backend scaled to 3
-frontend scaled to 5
-
-$ docker service ls
-
-ID            NAME      MODE        REPLICAS  IMAGE
-3pr5mlvu3fh9  frontend  replicated  5/5       nginx:alpine
-74nzcxxjv6fq  backend   replicated  3/3       redis:3.0.6
-```

-## Description
-
-Updates a service as described by the specified parameters. This command has to be run targeting a manager node.
-The parameters are the same as [`docker service create`](service_create.md). Please look at the description there
-for further information.
-
-Normally, updating a service will only cause the service's tasks to be replaced with new ones if a change to the
-service requires recreating the tasks for it to take effect. For example, only changing the
-`--update-parallelism` setting will not recreate the tasks, because the individual tasks are not affected by this
-setting. However, the `--force` flag will cause the tasks to be recreated anyway. This can be used to perform a
-rolling restart without any changes to the service parameters.
-
-## Examples
-
-### Update a service
-
-```bash
-$ docker service update --limit-cpu 2 redis
-```
-
-### Perform a rolling restart with no parameter changes
-
-```bash
-$ docker service update --force --update-parallelism 1 --update-delay 30s redis
-```
-
-In this example, the `--force` flag causes the service's tasks to be shut down
-and replaced with new ones even though none of the other parameters would
-normally cause that to happen. The `--update-parallelism 1` setting ensures
-that only one task is replaced at a time (this is the default behavior). The
-`--update-delay 30s` setting introduces a 30 second delay between tasks, so
-that the rolling restart happens gradually.
-
-### Add or remove mounts
-
-Use the `--mount-add` or `--mount-rm` options add or remove a service's bind-mounts
-or volumes.
-
-The following example creates a service which mounts the `test-data` volume to
-`/somewhere`. The next step updates the service to also mount the `other-volume`
-volume to `/somewhere-else`volume, The last step unmounts the `/somewhere` mount
-point, effectively removing the `test-data` volume. Each command returns the
-service name.
-
-- The `--mount-add` flag takes the same parameters as the `--mount` flag on
-  `service create`. Refer to the [volumes and
-  bind-mounts](service_create.md#volumes-and-bind-mounts-mount) section in the
-  `service create` reference for details.
-
-- The `--mount-rm` flag takes the `target` path of the mount.
-
-```bash
-$ docker service create \
-    --name=myservice \
-    --mount \
-      type=volume,source=test-data,target=/somewhere \
-    nginx:alpine \
-    myservice
-
-myservice
-
-$ docker service update \
-    --mount-add \
-      type=volume,source=other-volume,target=/somewhere-else \
-    myservice
-
-myservice
-
-$ docker service update --mount-rm /somewhere myservice
-
-myservice
-```
-
-### Rolling back to the previous version of a service 
-
-Use the `--rollback` option to roll back to the previous version of the service. 
-
-This will revert the service to the configuration that was in place before the most recent `docker service update` command.
-
-The following example updates the number of replicas for the service from 4 to 5, and then rolls back to the previous configuration.
-
-```bash
-$ docker service update --replicas=5 web
-
-web
-
-$ docker service ls
-
-ID            NAME  MODE        REPLICAS  IMAGE
-80bvrzp6vxf3  web   replicated  0/5       nginx:alpine
-
-```
-Roll back the `web` service... 
-
-```bash
-$ docker service update --rollback web
-
-web
-
-$ docker service ls
-
-ID            NAME  MODE        REPLICAS  IMAGE
-80bvrzp6vxf3  web   replicated  0/4       nginx:alpine
-
-```
-
-Other options can be combined with `--rollback` as well, for example, `--update-delay 0s` to execute the rollback without a delay between tasks:
-
-```bash
-$ docker service update \
-  --rollback \
-  --update-delay 0s
-  web
-
-web
-
-```
-
-Services can also be set up to roll back to the previous version automatically
-when an update fails. To set up a service for automatic rollback, use
-`--update-failure-action=rollback`. A rollback will be triggered if the fraction
-of the tasks which failed to update successfully exceeds the value given with
-`--update-max-failure-ratio`.
-
-The rate, parallelism, and other parameters of a rollback operation are
-determined by the values passed with the following flags:
-
-- `--rollback-delay`
-- `--rollback-failure-action`
-- `--rollback-max-failure-ratio`
-- `--rollback-monitor`
-- `--rollback-parallelism`
-
-For example, a service set up with `--update-parallelism 1 --rollback-parallelism 3`
-will update one task at a time during a normal update, but during a rollback, 3
-tasks at a time will get rolled back. These rollback parameters are respected both
-during automatic rollbacks and for rollbacks initiated manually using `--rollback`.
-
-### Add or remove secrets
-
-Use the `--secret-add` or `--secret-rm` options add or remove a service's
-secrets.
-
-The following example adds a secret named `ssh-2` and removes `ssh-1`:
-
-```bash
-$ docker service update \
-    --secret-add source=ssh-2,target=ssh-2 \
-    --secret-rm ssh-1 \
-    myservice
-```
-
-### Update services using templates
-
-Some flags of `service update` support the use of templating.
-See [`service create`](./service_create.md#templating) for the reference.

-# stack ls
-
-```markdown
-Usage:	docker stack ls
-
-List stacks
-
-Aliases:
-  ls, list
-
-Options:
-      --help            Print usage
-      --format string   Pretty-print stacks using a Go template
-```
-
-## Description
-
-Lists the stacks.
-
-## Examples
-
-The following command shows all stacks and some additional information:
-
-```bash
-$ docker stack ls
-
-ID                 SERVICES
-vossibility-stack  6
-myapp              2
-```
-
-### Formatting
-
-The formatting option (`--format`) pretty-prints stacks using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-| Placeholder | Description        |
-| ----------- | ------------------ |
-| `.Name`     | Stack name         |
-| `.Services` | Number of services |
-
-When using the `--format` option, the `stack ls` command either outputs
-the data exactly as the template declares or, when using the
-`table` directive, includes column headers as well.
-
-The following example uses a template without headers and outputs the
-`Name` and `Services` entries separated by a colon for all stacks:
-
-```bash
-$ docker stack ls --format "{{.Name}}: {{.Services}}"
-web-server: 1
-web-cache: 4
-```

-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there
-is more than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`).
-Multiple filter flags are combined as an `OR` filter. For example,
-`-f name=redis.1 -f name=redis.7` returns both `redis.1` and `redis.7` tasks.
-
-The currently supported filters are:
-
-* [id](#id)
-* [name](#name)
-* [node](#node)
-* [desired-state](#desired-state)
-
-#### id
-
-The `id` filter matches on all or a prefix of a task's ID.
-
-```bash
-$ docker stack ps -f "id=t" voting
-ID                  NAME                IMAGE               NODE         DESIRED STATE       CURRENTSTATE            ERROR  PORTS
-tz6j82jnwrx7        voting_db.1         postgres:9.4        node1        Running             Running 14 minutes ago
-t72q3z038jeh        voting_redis.2      redis:alpine        node3        Running             Running 14 minutes ago
-```
-
-#### name
-
-The `name` filter matches on task names.
-
-```bash
-$ docker stack ps -f "name=voting_redis" voting
-ID                  NAME                IMAGE               NODE         DESIRED STATE       CURRENTSTATE            ERROR  PORTS

-```
-
-#### node
-
-The `node` filter matches on a node name or a node ID.
-
-```bash
-$ docker stack ps -f "node=node1" voting
-ID                  NAME                  IMAGE                                          NODE   DESIRED STATE  CURRENT STATE          ERROR  PORTS

-```
-
-#### desired-state
-
-The `desired-state` filter can take the values `running`, `shutdown`, or `accepted`.
-
-```bash
-$ docker stack ps -f "desired-state=running" voting
-ID                  NAME                  IMAGE                                          NODE   DESIRED STATE  CURRENT STATE           ERROR  PORTS

-```
-
-### Formatting
-
-The formatting options (`--format`) pretty-prints tasks output using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-Placeholder     | Description
-----------------|------------------------------------------------------------------------------------------
-`.ID`           | Task ID
-`.Name`         | Task name
-`.Image`        | Task image
-`.Node`         | Node ID
-`.DesiredState` | Desired state of the task (`running`, `shutdown`, or `accepted`)
-`.CurrentState` | Current state of the task
-`.Error`        | Error
-`.Ports`        | Task published ports
-
-When using the `--format` option, the `stack ps` command will either
-output the data exactly as the template declares or, when using the
-`table` directive, includes column headers as well.
-
-The following example uses a template without headers and outputs the
-`Name` and `Image` entries separated by a colon for all tasks:
-
-```bash
-$ docker stack ps --format "{{.Name}}: {{.Image}}" voting
-voting_worker.1: dockersamples/examplevotingapp_worker:latest
-voting_result.1: dockersamples/examplevotingapp_result:before
-voting_vote.1: dockersamples/examplevotingapp_vote:before
-voting_db.1: postgres:9.4
-voting_redis.1: redis:alpine
-voting_visualizer.1: dockersamples/visualizer:stable
-voting_vote.2: dockersamples/examplevotingapp_vote:before
-voting_redis.2: redis:alpine
-```
-
-### Do not map IDs to Names
-
-The `--no-resolve` option shows IDs for task name, without mapping IDs to Names.
-
-```bash
-$ docker stack ps --no-resolve voting
-ID                  NAME                          IMAGE                                          NODE                        DESIRED STATE  CURRENT STATE            ERROR  PORTS

-```
-
-### Do not truncate output
-
-When deploying a service, docker resolves the digest for the service's
-image, and pins the service to that digest. The digest is not shown by
-default, but is printed if `--no-trunc` is used. The `--no-trunc` option
-also shows the non-truncated task IDs, and error-messages, as can be seen below:
-
-```bash
-$ docker stack ps --no-trunc voting
-ID                          NAME                  IMAGE                                                                                                                 NODE   DESIRED STATE  CURREN STATE           ERROR  PORTS

-```
-
-### Only display task IDs
-
-The `-q ` or `--quiet` option only shows IDs of the tasks in the stack.
-This example outputs all task IDs of the "voting" stack;
-
-```bash
-$ docker stack ps -q voting
-xim5bcqtgk1b
-q7yik0ks1in6
-rx5yo0866nfx
-tz6j82jnwrx7
-w48spazhbmxc
-6jj1m02freg1
-kqgdmededccb
-t72q3z038jeh
-```
-
-This option can be used to perform batch operations. For example, you can use
-the task IDs as input for other commands, such as `docker inspect`. The
-following example inspects all tasks of the "voting" stack;
-
-```bash
-$ docker inspect $(docker stack ps -q voting)
-
-[
-    {
-        "ID": "xim5bcqtgk1b1gk0krq1",
-        "Version": {
-(...)

-# stack services (experimental)
-
-```markdown
-Usage:	docker stack services [OPTIONS] STACK
-
-List the services in the stack
-
-Options:
-  -f, --filter filter   Filter output based on conditions provided
-      --format string   Pretty-print services using a Go template
-      --help            Print usage
-  -q, --quiet           Only display IDs
-```
-
-## Description
-
-Lists the services that are running as part of the specified stack. This
-command has to be run targeting a manager node.
-
-## Examples
-
-The following command shows all services in the `myapp` stack:
-
-```bash
-$ docker stack services myapp
-
-ID            NAME            REPLICAS  IMAGE                                                                          COMMAND
-7be5ei6sqeye  myapp_web       1/1       nginx@sha256:23f809e7fd5952e7d5be065b4d3643fbbceccd349d537b62a123ef2201bc886f
-dn7m7nhhfb9y  myapp_db        1/1       mysql@sha256:a9a5b559f8821fe73d58c3606c812d1c044868d42c63817fa5125fd9d8b7b539
-```
-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there
-is more than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`).
-Multiple filter flags are combined as an `OR` filter.
-
-The following command shows both the `web` and `db` services:
-
-```bash
-$ docker stack services --filter name=myapp_web --filter name=myapp_db myapp
-
-ID            NAME            REPLICAS  IMAGE                                                                          COMMAND
-7be5ei6sqeye  myapp_web       1/1       nginx@sha256:23f809e7fd5952e7d5be065b4d3643fbbceccd349d537b62a123ef2201bc886f
-dn7m7nhhfb9y  myapp_db        1/1       mysql@sha256:a9a5b559f8821fe73d58c3606c812d1c044868d42c63817fa5125fd9d8b7b539
-```
-
-The currently supported filters are:
-
-* id / ID (`--filter id=7be5ei6sqeye`, or `--filter ID=7be5ei6sqeye`)
-* name (`--filter name=myapp_web`)
-* label (`--filter label=key=value`)
-
-### Formatting
-
-The formatting options (`--format`) pretty-prints services output
-using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-Placeholder | Description
-------------|------------------------------------------------------------------------------------------
-`.ID`       | Service ID
-`.Name`     | Service name
-`.Mode`     | Service mode (replicated, global)
-`.Replicas` | Service replicas
-`.Image`    | Service image
-
-When using the `--format` option, the `stack services` command will either
-output the data exactly as the template declares or, when using the
-`table` directive, includes column headers as well.
-
-The following example uses a template without headers and outputs the
-`ID`, `Mode`, and `Replicas` entries separated by a colon for all services:
-
-```bash
-$ docker stack services --format "{{.ID}}: {{.Mode}} {{.Replicas}}"
-
-0zmvwuiu3vue: replicated 10/10
-fm6uf97exkul: global 5/5
-```
-

-# stats
-
-```markdown
-Usage:  docker stats [OPTIONS] [CONTAINER...]
-
-Display a live stream of container(s) resource usage statistics
-
-Options:
-  -a, --all             Show all containers (default shows just running)
-      --format string   Pretty-print images using a Go template
-      --help            Print usage
-      --no-stream       Disable streaming stats and only pull the first result
-```
-
-## Description
-
-The `docker stats` command returns a live data stream for running containers. To limit data to one or more specific containers, specify a list of container names or ids separated by a space. You can specify a stopped container but stopped containers do not return any data.
-
-If you want more detailed information about a container's resource usage, use the `/containers/(id)/stats` API endpoint.
-
-## Examples
-
-Running `docker stats` on all running containers against a Linux daemon.
-
-```bash
-$ docker stats

-
-### `--rotate`
-
-Root CA Rotation is recommended if one or more of the swarm managers have been
-compromised, so that those managers can no longer connect to or be trusted by
-any other node in the cluster.
-
-Alternately, root CA rotation can be used to give control of the swarm CA
-to an external CA, or to take control back from an external CA.
-
-The `--rotate` flag does not require any parameters to do a rotation, but you can
-optionally specify a certificate and key, or a certificate and external CA URL,
-and those will be used instead of an automatically-generated certificate/key pair.
-
-Because the root CA key should be kept secret, if provided it will not be visible
-when viewing swarm any information via the CLI or API.
-
-The root CA rotation will not be completed until all registered nodes have
-rotated their TLS certificates.  If the rotation is not completing within a
-reasonable amount of time, try running
-`docker node ls --format {{.ID}} {{.Hostname}} {{.Status}} {{.TLSStatus}}` to
-see if any nodes are down or otherwise unable to rotate TLS certificates.
-
-
-### `--detach`
-
-Initiate the root CA rotation, but do not wait for the completion of or display the
-progress of the rotation.

-
-## Description
-
-Initialize a swarm. The docker engine targeted by this command becomes a manager
-in the newly created single-node swarm.
-
-## Examples
-
-```bash
-$ docker swarm init --advertise-addr 192.168.99.121
-Swarm initialized: current node (bvz81updecsj6wjz393c09vti) is now a manager.
-
-To add a worker to this swarm, run the following command:
-
-    docker swarm join \
-    --token SWMTKN-1-3pu6hszjas19xyp7ghgosyx9k8atbfcr8p2is99znpy26u2lkl-1awxwuwd3z9j1z3puu7rcgdbx \
-    172.17.0.2:2377
-
-To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
-```
-
-`docker swarm init` generates two random tokens, a worker token and a manager token. When you join
-a new node to the swarm, the node joins as a worker or manager node based upon the token you pass
-to [swarm join](swarm_join.md).
-
-After you create the swarm, you can display or rotate the token using
-[swarm join-token](swarm_join_token.md).
-
-### `--autolock`
-
-This flag enables automatic locking of managers with an encryption key. The
-private keys and data stored by all managers will be protected by the
-encryption key printed in the output, and will not be accessible without it.
-Thus, it is very important to store this key in order to activate a manager
-after it restarts. The key can be passed to `docker swarm unlock` to reactivate
-the manager. Autolock can be disabled by running
-`docker swarm update --autolock=false`. After disabling it, the encryption key
-is no longer required to start the manager, and it will start up on its own
-without user intervention.
-
-### `--cert-expiry`
-
-This flag sets the validity period for node certificates.
-
-### `--dispatcher-heartbeat`
-
-This flag sets the frequency with which nodes are told to use as a
-period to report their health.
-
-### `--external-ca`
-
-This flag sets up the swarm to use an external CA to issue node certificates. The value takes
-the form `protocol=X,url=Y`. The value for `protocol` specifies what protocol should be used
-to send signing requests to the external CA. Currently, the only supported value is `cfssl`.
-The URL specifies the endpoint where signing requests should be submitted.
-
-### `--force-new-cluster`
-
-This flag forces an existing node that was part of a quorum that was lost to restart as a single node Manager without losing its data.
-
-### `--listen-addr`
-
-The node listens for inbound swarm manager traffic on this address. The default is to listen on
-0.0.0.0:2377. It is also possible to specify a network interface to listen on that interface's
-address; for example `--listen-addr eth0:2377`.
-
-Specifying a port is optional. If the value is a bare IP address or interface
-name, the default port 2377 will be used.
-
-### `--advertise-addr`
-
-This flag specifies the address that will be advertised to other members of the
-swarm for API access and overlay networking. If unspecified, Docker will check
-if the system has a single IP address, and use that IP address with the
-listening port (see `--listen-addr`). If the system has multiple IP addresses,
-`--advertise-addr` must be specified so that the correct address is chosen for
-inter-manager communication and overlay networking.
-
-It is also possible to specify a network interface to advertise that interface's address;
-for example `--advertise-addr eth0:2377`.
-
-Specifying a port is optional. If the value is a bare IP address or interface
-name, the default port 2377 will be used.
-
-### `--data-path-addr`
-
-This flag specifies the address that global scope network drivers will publish towards
-other nodes in order to reach the containers running on this node.
-Using this parameter it is then possible to separate the container's data traffic from the
-management traffic of the cluster.
-If unspecified, Docker will use the same IP address or interface that is used for the
-advertise address.
-
-### `--task-history-limit`
-
-This flag sets up task history retention limit.
-
-### `--max-snapshots`
-
-This flag sets the number of old Raft snapshots to retain in addition to the
-current Raft snapshots. By default, no old snapshots are retained. This option
-may be used for debugging, or to store old snapshots of the swarm state for
-disaster recovery purposes.
-
-### `--snapshot-interval`
-
-This flag specifies how many log entries to allow in between Raft snapshots.
-Setting this to a higher number will trigger snapshots less frequently.
-Snapshots compact the Raft log and allow for more efficient transfer of the
-state to new managers. However, there is a performance cost to taking snapshots
-frequently.
-
-### `--availability`
-
-This flag specifies the availability of the node at the time the node joins a master.
-Possible availability values are `active`, `pause`, or `drain`.
-
-This flag is useful in certain situations. For example, a cluster may want to have
-dedicated manager nodes that are not served as worker nodes. This could be achieved
-by passing `--availability=drain` to `docker swarm init`.

-
-```markdown
-Usage:  docker swarm join [OPTIONS] HOST:PORT
-
-Join a swarm as a node and/or manager
-
-Options:
-      --advertise-addr string   Advertised address (format: <ip|interface>[:port])
-      --availability string     Availability of the node ("active"|"pause"|"drain") (default "active")

-      --token string            Token for entry into the swarm
-```
-
-## Description
-
-Join a node to a swarm. The node joins as a manager node or worker node based upon the token you
-pass with the `--token` flag. If you pass a manager token, the node joins as a manager. If you
-pass a worker token, the node joins as a worker.
-
-## Examples
-
-### Join a node to swarm as a manager
-
-The example below demonstrates joining a manager node using a manager token.
-
-```bash
-$ docker swarm join --token SWMTKN-1-3pu6hszjas19xyp7ghgosyx9k8atbfcr8p2is99znpy26u2lkl-7p73s1dx5in4tatdymyhg9hu2 192.168.99.121:2377
-This node joined a swarm as a manager.
-$ docker node ls
-ID                           HOSTNAME  STATUS  AVAILABILITY  MANAGER STATUS
-dkp8vy1dq1kxleu9g4u78tlag *  manager2  Ready   Active        Reachable
-dvfxp4zseq4s0rih1selh0d20    manager1  Ready   Active        Leader
-```
-
-A cluster should only have 3-7 managers at most, because a majority of managers must be available
-for the cluster to function. Nodes that aren't meant to participate in this management quorum
-should join as workers instead. Managers should be stable hosts that have static IP addresses.
-
-### Join a node to swarm as a worker
-
-The example below demonstrates joining a worker node using a worker token.
-
-```bash
-$ docker swarm join --token SWMTKN-1-3pu6hszjas19xyp7ghgosyx9k8atbfcr8p2is99znpy26u2lkl-1awxwuwd3z9j1z3puu7rcgdbx 192.168.99.121:2377
-This node joined a swarm as a worker.
-$ docker node ls

-dvfxp4zseq4s0rih1selh0d20 *  manager1  Ready   Active        Leader
-```
-
-### `--listen-addr value`
-
-If the node is a manager, it will listen for inbound swarm manager traffic on this
-address. The default is to listen on 0.0.0.0:2377. It is also possible to specify a
-network interface to listen on that interface's address; for example `--listen-addr eth0:2377`.
-
-Specifying a port is optional. If the value is a bare IP address, or interface
-name, the default port 2377 will be used.
-
-This flag is generally not necessary when joining an existing swarm.
-
-### `--advertise-addr value`
-
-This flag specifies the address that will be advertised to other members of the
-swarm for API access. If unspecified, Docker will check if the system has a
-single IP address, and use that IP address with the listening port (see
-`--listen-addr`). If the system has multiple IP addresses, `--advertise-addr`
-must be specified so that the correct address is chosen for inter-manager
-communication and overlay networking.
-
-It is also possible to specify a network interface to advertise that interface's address;
-for example `--advertise-addr eth0:2377`.
-
-Specifying a port is optional. If the value is a bare IP address, or interface
-name, the default port 2377 will be used.
-
-This flag is generally not necessary when joining an existing swarm.
-
-### `--data-path-addr`
-
-This flag specifies the address that global scope network drivers will publish towards
-other nodes in order to reach the containers running on this node.
-Using this parameter it is then possible to separate the container's data traffic from the
-management traffic of the cluster.
-If unspecified, Docker will use the same IP address or interface that is used for the
-advertise address.
-
-### `--token string`
-
-Secret value required for nodes to join the swarm
-
-### `--availability`
-
-This flag specifies the availability of the node at the time the node joins a master.
-Possible availability values are `active`, `pause`, or `drain`.
-
-This flag is useful in certain situations. For example, a cluster may want to have
-dedicated manager nodes that are not served as worker nodes. This could be achieved
-by passing `--availability=drain` to `docker swarm join`.

-Usage:	docker swarm join-token [OPTIONS] (worker|manager)
-
-Manage join tokens
-
-Options:
-      --help     Print usage
-  -q, --quiet    Only display token
-      --rotate   Rotate join token
-```
-
-## Description
-
-Join tokens are secrets that allow a node to join the swarm. There are two
-different join tokens available, one for the worker role and one for the manager
-role. You pass the token using the `--token` flag when you run
-[swarm join](swarm_join.md). Nodes use the join token only when they join the
-swarm.
-
-## Examples
-
-You can view or rotate the join tokens using `swarm join-token`.
-
-As a convenience, you can pass `worker` or `manager` as an argument to
-`join-token` to print the full `docker swarm join` command to join a new node to
-the swarm:
-
-```bash
-$ docker swarm join-token worker
-To add a worker to this swarm, run the following command:
-
-    docker swarm join \
-    --token SWMTKN-1-3pu6hszjas19xyp7ghgosyx9k8atbfcr8p2is99znpy26u2lkl-1awxwuwd3z9j1z3puu7rcgdbx \
-    172.17.0.2:2377
-
-$ docker swarm join-token manager
-To add a manager to this swarm, run the following command:
-
-    docker swarm join \
-    --token SWMTKN-1-3pu6hszjas19xyp7ghgosyx9k8atbfcr8p2is99znpy26u2lkl-7p73s1dx5in4tatdymyhg9hu2 \
-    172.17.0.2:2377
-```
-
-Use the `--rotate` flag to generate a new join token for the specified role:
-
-```bash
-$ docker swarm join-token --rotate worker
-Successfully rotated worker join token.
-
-To add a worker to this swarm, run the following command:
-
-    docker swarm join \
-    --token SWMTKN-1-3pu6hszjas19xyp7ghgosyx9k8atbfcr8p2is99znpy26u2lkl-b30ljddcqhef9b9v4rs7mel7t \
-    172.17.0.2:2377
-```
-
-After using `--rotate`, only the new token will be valid for joining with the specified role.
-
-The `-q` (or `--quiet`) flag only prints the token:
-
-```bash
-$ docker swarm join-token -q worker
-
-SWMTKN-1-3pu6hszjas19xyp7ghgosyx9k8atbfcr8p2is99znpy26u2lkl-b30ljddcqhef9b9v4rs7mel7t
-```
-
-### `--rotate`
-
-Because tokens allow new nodes to join the swarm, you should keep them secret.
-Be particularly careful with manager tokens since they allow new manager nodes
-to join the swarm. A rogue manager has the potential to disrupt the operation of
-your swarm.
-
-Rotate your swarm's join token if a token gets checked-in to version control,
-stolen, or a node is compromised. You may also want to periodically rotate the
-token to ensure any unknown token leaks do not allow a rogue node to join
-the swarm.
-
-To rotate the join token and print the newly generated token, run
-`docker swarm join-token --rotate` and pass the role: `manager` or `worker`.
-
-Rotating a join-token means that no new nodes will be able to join the swarm
-using the old token. Rotation does not affect existing nodes in the swarm
-because the join token is only used for authorizing new nodes joining the swarm.
-
-### `--quiet`
-
-Only print the token. Do not print a complete command for joining.

-# swarm leave
-
-```markdown
-Usage:	docker swarm leave [OPTIONS]
-
-Leave the swarm
-
-Options:
-  -f, --force   Force this node to leave the swarm, ignoring warnings
-      --help    Print usage
-```
-
-## Description
-
-When you run this command on a worker, that worker leaves the swarm.
-
-You can use the `--force` option on a manager to remove it from the swarm.
-However, this does not reconfigure the swarm to ensure that there are enough
-managers to maintain a quorum in the swarm. The safe way to remove a manager
-from a swarm is to demote it to a worker and then direct it to leave the quorum
-without using `--force`. Only use `--force` in situations where the swarm will
-no longer be used after the manager leaves, such as in a single-node swarm.
-
-## Examples
-
-Consider the following swarm, as seen from the manager:
-
-```bash
-$ docker node ls
-ID                           HOSTNAME  STATUS  AVAILABILITY  MANAGER STATUS
-7ln70fl22uw2dvjn2ft53m3q5    worker2   Ready   Active
-dkp8vy1dq1kxleu9g4u78tlag    worker1   Ready   Active
-dvfxp4zseq4s0rih1selh0d20 *  manager1  Ready   Active        Leader
-```
-
-To remove `worker2`, issue the following command from `worker2` itself:
-
-```bash
-$ docker swarm leave
-Node left the default swarm.
-```
-
-The node will still appear in the node list, and marked as `down`. It no longer
-affects swarm operation, but a long list of `down` nodes can clutter the node
-list. To remove an inactive node from the list, use the [`node rm`](node_rm.md)
-command.

-used to reactivate a manager after its Docker daemon restarts if the autolock
-setting is turned on. The unlock key is printed at the time when autolock is
-enabled, and is also available from the `docker swarm unlock-key` command.

-## Examples
-
-```bash
-$ docker swarm unlock
-Please enter unlock key:

-```markdown
-Usage:	docker swarm unlock-key [OPTIONS]
-
-Manage the unlock key
-
-Options:
-      --help     Print usage
-  -q, --quiet    Only display token
-      --rotate   Rotate unlock key

-
-## Description
-
-An unlock key is a secret key needed to unlock a manager after its Docker daemon
-restarts. These keys are only used when the autolock feature is enabled for the
-swarm.
-
-You can view or rotate the unlock key using `swarm unlock-key`. To view the key,
-run the `docker swarm unlock-key` command without any arguments:
-
-## Examples
-
-```bash
-$ docker swarm unlock-key
-
-To unlock a swarm manager after it restarts, run the `docker swarm unlock`
-command and provide the following key:
-
-    SWMKEY-1-fySn8TY4w5lKcWcJPIpKufejh9hxx5KYwx6XZigx3Q4
-
-Please remember to store this key in a password manager, since without it you
-will not be able to restart the manager.
-```
-
-Use the `--rotate` flag to rotate the unlock key to a new, randomly-generated
-key:
-
-```bash
-$ docker swarm unlock-key --rotate
-Successfully rotated manager unlock key.
-
-To unlock a swarm manager after it restarts, run the `docker swarm unlock`
-command and provide the following key:
-
-    SWMKEY-1-7c37Cc8654o6p38HnroywCi19pllOnGtbdZEgtKxZu8
-
-Please remember to store this key in a password manager, since without it you
-will not be able to restart the manager.
-```
-
-The `-q` (or `--quiet`) flag only prints the key:
-
-```bash
-$ docker swarm unlock-key -q
-SWMKEY-1-7c37Cc8654o6p38HnroywCi19pllOnGtbdZEgtKxZu8
-```
-
-### `--rotate`
-
-This flag rotates the unlock key, replacing it with a new randomly-generated
-key. The old unlock key will no longer be accepted.
-
-### `--quiet`
-
-Only print the unlock key, without instructions.

-
-* `SHARED SIZE` is the amount of space that an image shares with another one (i.e. their common data)
-* `UNIQUE SIZE` is the amount of space that is only used by a given image
-* `SIZE` is the virtual size of the image, it is the sum of `SHARED SIZE` and `UNIQUE SIZE`
-
-> **Note**: Network information is not shown because it doesn't consume the disk
-> space.
-
-## Performance
-
-The `system df` command can be very resource-intensive. It traverses the
-filesystem of every image, container, and volume in the system. You should be
-careful running this command in systems with lots of images, containers, or
-volumes or in systems where some images, containers, or volumes have very large
-filesystems with many files. You should also be careful not to run this command
-in systems where performance is critical.
-
-## Format the output
-
-The formatting option (`--format`) pretty prints the disk usage output
-using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-| Placeholder    | Description                                |
-| -------------- | ------------------------------------------ |
-| `.Type`        | `Images`, `Containers` and `Local Volumes` |
-| `.TotalCount`  | Total number of items                      |
-| `.Active`      | Number of active items                     |
-| `.Size`        | Available size                             |
-| `.Reclaimable` | Reclaimable size                           |
-
-When using the `--format` option, the `system df` command outputs
-the data exactly as the template declares or, when using the
-`table` directive, will include column headers as well.
-
-The following example uses a template without headers and outputs the
-`Type` and `TotalCount` entries separated by a colon:
-
-```bash
-$ docker system df --format "{{.Type}}: {{.TotalCount}}"
-
-Images: 2
-Containers: 4
-Local Volumes: 1
-```
-
-To list the disk usage with size and reclaimable size in a table format you
-can use:
-
-```bash
-$ docker system df --format "table {{.Type}}\t{{.Size}}\t{{.Reclaimable}}"
-
-TYPE                SIZE                RECLAIMABLE
-Images              2.547 GB            2.342 GB (91%)
-Containers          0 B                 0 B
-Local Volumes       150.3 MB            150.3 MB (100%)
-<Paste>
-```
-
-**Note** the format option is meaningless when verbose is true.

-# system events
-
-```markdown
-Usage:  docker system events [OPTIONS]
-
-Get real time events from the server
-
-Options:
-  -f, --filter value   Filter output based on conditions provided (default [])
-      --format string  Format the output using the given Go template
-      --help           Print usage
-      --since string   Show all events created since timestamp
-      --until string   Stream events until this timestamp
-```
-
-## Description
-
-Use `docker system events` to get real-time events from the server. These
-events differ per Docker object type.
-
-### Object types
-
-#### Containers
-
-Docker containers report the following events:
-
-- `attach`
-- `commit`
-- `copy`
-- `create`
-- `destroy`
-- `detach`
-- `die`
-- `exec_create`
-- `exec_detach`
-- `exec_start`
-- `export`
-- `health_status`
-- `kill`
-- `oom`
-- `pause`
-- `rename`
-- `resize`
-- `restart`
-- `start`
-- `stop`
-- `top`
-- `unpause`
-- `update`
-
-#### Images
-
-Docker images report the following events:
-
-- `delete`
-- `import`
-- `load`
-- `pull`
-- `push`
-- `save`
-- `tag`
-- `untag`
-
-#### Plugins
-
-Docker plugins report the following events:
-
-- `install`
-- `enable`
-- `disable`
-- `remove`
-
-#### Volumes
-
-Docker volumes report the following events:
-
-- `create`
-- `mount`
-- `unmount`
-- `destroy`
-
-#### Networks
-
-Docker networks report the following events:
-
-- `create`
-- `connect`
-- `disconnect`
-- `destroy`
-
-#### Daemons
-
-Docker daemons report the following events:
-
-- `reload`
-
-### Limiting, filtering, and formatting the output
-
-#### Limit events by time
-
-The `--since` and `--until` parameters can be Unix timestamps, date formatted
-timestamps, or Go duration strings (e.g. `10m`, `1h30m`) computed
-relative to the client machine’s time. If you do not provide the `--since` option,
-the command returns only new and/or live events.  Supported formats for date
-formatted time stamps include RFC3339Nano, RFC3339, `2006-01-02T15:04:05`,
-`2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
-timezone on the client will be used if you do not provide either a `Z` or a
-`+-00:00` timezone offset at the end of the timestamp.  When providing Unix
-timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
-that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
-seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
-fraction of a second no more than nine digits long.
-
-#### Filtering
-
-The filtering flag (`-f` or `--filter`) format is of "key=value". If you would
-like to use multiple filters, pass multiple flags (e.g.,
-`--filter "foo=bar" --filter "bif=baz"`)
-
-Using the same filter multiple times will be handled as a *OR*; for example
-`--filter container=588a23dac085 --filter container=a8f7720b8c22` will display
-events for container 588a23dac085 *OR* container a8f7720b8c22
-
-Using multiple filters will be handled as a *AND*; for example
-`--filter container=588a23dac085 --filter event=start` will display events for
-container container 588a23dac085 *AND* the event type is *start*
-
-The currently supported filters are:
-
-* container (`container=<name or id>`)
-* daemon (`daemon=<name or id>`)
-* event (`event=<event action>`)
-* image (`image=<tag or id>`)
-* label (`label=<key>` or `label=<key>=<value>`)
-* network (`network=<name or id>`)
-* plugin (`plugin=<name or id>`)
-* type (`type=<container or image or volume or network or daemon or plugin>`)
-* volume (`volume=<name or id>`)
-
-#### Format
-
-If a format (`--format`) is specified, the given template will be executed
-instead of the default
-format. Go's [text/template](http://golang.org/pkg/text/template/) package
-describes all the details of the format.
-
-If a format is set to `{{json .}}`, the events are streamed as valid JSON
-Lines. For information about JSON Lines, please refer to http://jsonlines.org/ .
-
-## Examples
-
-### Basic example
-
-You'll need two shells for this example.
-
-**Shell 1: Listening for events:**
-
-```bash
-$ docker system events
-```
-
-**Shell 2: Start and Stop containers:**
-
-```bash
-$ docker create --name test alpine:latest top
-$ docker start test
-$ docker stop test
-```
-
-**Shell 1: (Again .. now showing events):**
-
-```none

-### Filter events by time
-
-You can filter the output by an absolute timestamp or relative time on the host
-machine, using the following different time syntaxes:
-
-```bash

-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
-than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
-
-The currently supported filters are:
-
-* until (`<timestamp>`) - only remove containers, images, and networks created before given timestamp
-* label (`label=<key>`, `label=<key>=<value>`, `label!=<key>`, or `label!=<key>=<value>`) - only remove containers, images, networks, and volumes with (or without, in case `label!=...` is used) the specified labels.
-
-The `until` filter can be Unix timestamps, date formatted
-timestamps, or Go duration strings (e.g. `10m`, `1h30m`) computed
-relative to the daemon machine’s time. Supported formats for date
-formatted time stamps include RFC3339Nano, RFC3339, `2006-01-02T15:04:05`,
-`2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
-timezone on the daemon will be used if you do not provide either a `Z` or a
-`+-00:00` timezone offset at the end of the timestamp.  When providing Unix
-timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
-that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
-seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
-fraction of a second no more than nine digits long.
-
-The `label` filter accepts two formats. One is the `label=...` (`label=<key>` or `label=<key>=<value>`),
-which removes containers, images, networks, and volumes with the specified labels. The other
-format is the `label!=...` (`label!=<key>` or `label!=<key>=<value>`), which removes
-containers, images, networks, and volumes without the specified labels.

-# tag
-
-```markdown
-Usage:  docker tag SOURCE_IMAGE[:TAG] TARGET_IMAGE[:TAG]
-
-Create a tag TARGET_IMAGE that refers to SOURCE_IMAGE
-
-Options:

-```
-
-## Description
-
-An image name is made up of slash-separated name components, optionally prefixed
-by a registry hostname. The hostname must comply with standard DNS rules, but
-may not contain underscores. If a hostname is present, it may optionally be
-followed by a port number in the format `:8080`. If not present, the command
-uses Docker's public registry located at `registry-1.docker.io` by default. Name
-components may contain lowercase letters, digits and separators. A separator
-is defined as a period, one or two underscores, or one or more dashes. A name
-component may not start or end with a separator.
-
-A tag name must be valid ASCII and may contain lowercase and uppercase letters,
-digits, underscores, periods and dashes. A tag name may not start with a
-period or a dash and may contain a maximum of 128 characters.
-
-You can group your images together using names and tags, and then upload them
-to [*Share Images via Repositories*](https://docs.docker.com/engine/tutorials/dockerrepos/#/contributing-to-docker-hub).
-
-## Examples
-
-### Tag an image referenced by ID
-
-To tag a local image with ID "0e5574283393" into the "fedora" repository with
-"version1.0":
-
-```bash
-$ docker tag 0e5574283393 fedora/httpd:version1.0
-```
-
-### Tag an image referenced by Name
-
-To tag a local image with name "httpd" into the "fedora" repository with
-"version1.0":
-
-```bash
-$ docker tag httpd fedora/httpd:version1.0
-```
-
-Note that since the tag name is not specified, the alias is created for an
-existing local version `httpd:latest`.
-
-### Tag an image referenced by Name and Tag
-
-To tag a local image with name "httpd" and tag "test" into the "fedora"
-repository with "version1.0.test":
-
-```bash
-$ docker tag httpd:test fedora/httpd:version1.0.test
-```
-
-### Tag an image for a private repository
-
-To push an image to a private registry and not the central Docker
-registry you must tag it with the registry hostname and port (if needed).
-
-```bash
-$ docker tag 0e5574283393 myregistryhost:5000/fedora/httpd:version1.0
-```

-
-## Description
-
-The `docker update` command dynamically updates container configuration.
-You can use this command to prevent containers from consuming too many
-resources from their Docker host.  With a single command, you can place
-limits on a single container or on many. To specify more than one container,
-provide space-separated list of container names or IDs.
-
-With the exception of the `--kernel-memory` option, you can specify these
-options on a running or a stopped container. On kernel version older than
-4.6, you can only update `--kernel-memory` on a stopped container or on
-a running container with kernel memory initialized.
-
-## Examples
-
-The following sections illustrate ways to use this command.
-
-### Update a container's cpu-shares
-
-To limit a container's cpu-shares to 512, first identify the container
-name or ID. You can use `docker ps` to find these values. You can also
-use the ID returned from the `docker run` command.  Then, do the following:
-
-```bash
-$ docker update --cpu-shares 512 abebf7571666
-```
-
-### Update a container with cpu-shares and memory
-
-To update multiple resource configurations for multiple containers:
-
-```bash
-$ docker update --cpu-shares 512 -m 300M abebf7571666 hopeful_morse
-```
-
-### Update a container's kernel memory constraints
-
-You can update a container's kernel memory limit using the `--kernel-memory`
-option. On kernel version older than 4.6, this option can be updated on a
-running container only if the container was started with `--kernel-memory`.
-If the container was started *without* `--kernel-memory` you need to stop
-the container before updating kernel memory.
-
-For example, if you started a container with this command:
-
-```bash
-$ docker run -dit --name test --kernel-memory 50M ubuntu bash
-```
-
-You can update kernel memory while the container is running:
-
-```bash
-$ docker update --kernel-memory 80M test
-```
-
-If you started a container *without* kernel memory initialized:
-
-```bash
-$ docker run -dit --name test2 --memory 300M ubuntu bash
-```
-
-Update kernel memory of running container `test2` will fail. You need to stop
-the container before updating the `--kernel-memory` setting. The next time you
-start it, the container uses the new value.
-
-Kernel version newer than (include) 4.6 does not have this limitation, you
-can use `--kernel-memory` the same way as other options.
-
-### Update a container's restart policy
-
-You can change a container's restart policy on a running container. The new
-restart policy takes effect instantly after you run `docker update` on a
-container.
-
-To update restart policy for one or more containers:
-
-```bash
-$ docker update --restart=on-failure:3 abebf7571666 hopeful_morse
-```
-
-Note that if the container is started with "--rm" flag, you cannot update the restart
-policy for it. The `AutoRemove` and `RestartPolicy` are mutually exclusive for the
-container.

-# volume create
-
-```markdown
-Usage:  docker volume create [OPTIONS] [VOLUME]
-
-Create a volume
-
-Options:
-  -d, --driver string   Specify volume driver name (default "local")
-      --help            Print usage
-      --label value     Set metadata for a volume (default [])
-  -o, --opt value       Set driver specific options (default map[])
-```
-
-## Description
-
-Creates a new volume that containers can consume and store data in. If a name is
-not specified, Docker generates a random name.
-
-## Examples
-
-Create a volume and then configure the container to use it:
-
-```bash
-$ docker volume create hello
-
-hello
-
-$ docker run -d -v hello:/world busybox ls /world
-```
-
-The mount is created inside the container's `/world` directory. Docker does not
-support relative paths for mount points inside the container.
-
-Multiple containers can use the same volume in the same time period. This is
-useful if two containers need access to shared data. For example, if one
-container writes and the other reads the data.
-
-Volume names must be unique among drivers. This means you cannot use the same
-volume name with two different drivers. If you attempt this `docker` returns an
-error:
-
-```none
-A volume named  "hello"  already exists with the "some-other" driver. Choose a different volume name.
-```
-
-If you specify a volume name already in use on the current driver, Docker
-assumes you want to re-use the existing volume and does not return an error.
-
-### Driver-specific options
-
-Some volume drivers may take options to customize the volume creation. Use the
-`-o` or `--opt` flags to pass driver options:
-
-```bash
-$ docker volume create --driver fake \
-    --opt tardis=blue \
-    --opt timey=wimey \
-    foo
-```
-
-These options are passed directly to the volume driver. Options for
-different volume drivers may do different things (or nothing at all).
-
-The built-in `local` driver on Windows does not support any options.
-
-The built-in `local` driver on Linux accepts options similar to the linux
-`mount` command. You can provide multiple options by passing the `--opt` flag
-multiple times. Some `mount` options (such as the `o` option) can take a
-comma-separated list of options. Complete list of available mount options can be
-found [here](http://man7.org/linux/man-pages/man8/mount.8.html).
-
-For example, the following creates a `tmpfs` volume called `foo` with a size of
-100 megabyte and `uid` of 1000.
-
-```bash
-$ docker volume create --driver local \
-    --opt type=tmpfs \
-    --opt device=tmpfs \
-    --opt o=size=100m,uid=1000 \
-    foo
-```
-
-Another example that uses `btrfs`:
-
-```bash
-$ docker volume create --driver local \
-    --opt type=btrfs \
-    --opt device=/dev/sda2 \
-    foo
-```
-
-Another example that uses `nfs` to mount the `/path/to/dir` in `rw` mode from
-`192.168.1.1`:
-
-```bash
-$ docker volume create --driver local \
-    --opt type=nfs \
-    --opt o=addr=192.168.1.1,rw \
-    --opt device=:/path/to/dir \
-    foo
-```

-      --format string  Pretty-print volumes using a Go template
-      --help           Print usage
-  -q, --quiet          Only display volume names
-```
-
-## Description
-
-List all the volumes known to Docker. You can filter using the `-f` or
-`--filter` flag. Refer to the [filtering](#filtering) section for more
-information about available filter options.
-
-## Examples
-
-### Create a volume
-```bash
-$ docker volume create rosemary
-
-rosemary
-
-$ docker volume create tyler
-
-tyler
-
-$ docker volume ls
-
-DRIVER              VOLUME NAME
-local               rosemary
-local               tyler
-```
-
-### Filtering
-
-The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
-than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
-
-The currently supported filters are:
-
-* dangling (boolean - true or false, 0 or 1)
-* driver (a volume driver's name)
-* label (`label=<key>` or `label=<key>=<value>`)
-* name (a volume's name)
-
-#### dangling
-
-The `dangling` filter matches on all volumes not referenced by any containers
-
-```bash
-$ docker run -d  -v tyler:/tmpwork  busybox
-
-f86a7dd02898067079c99ceacd810149060a70528eff3754d0b0f1a93bd0af18
-$ docker volume ls -f dangling=true
-DRIVER              VOLUME NAME
-local               rosemary
-```
-
-#### driver
-
-The `driver` filter matches volumes based on their driver.
-
-The following example matches volumes that are created with the `local` driver:
-
-```bash
-$ docker volume ls -f driver=local
-
-DRIVER              VOLUME NAME
-local               rosemary
-local               tyler
-```
-
-#### label
-
-The `label` filter matches volumes based on the presence of a `label` alone or
-a `label` and a value.
-
-First, let's create some volumes to illustrate this;
-
-```bash
-$ docker volume create the-doctor --label is-timelord=yes
-
-the-doctor
-$ docker volume create daleks --label is-timelord=no
-
-daleks
-```
-
-The following example filter matches volumes with the `is-timelord` label
-regardless of its value.
-
-```bash
-$ docker volume ls --filter label=is-timelord
-
-DRIVER              VOLUME NAME
-local               daleks
-local               the-doctor
-```
-
-As the above example demonstrates, both volumes with `is-timelord=yes`, and
-`is-timelord=no` are returned.
-
-Filtering on both `key` *and* `value` of the label, produces the expected result:
-
-```bash
-$ docker volume ls --filter label=is-timelord=yes
-
-DRIVER              VOLUME NAME
-local               the-doctor
-```
-
-Specifying multiple label filter produces an "and" search; all conditions
-should be met;
-
-```bash
-$ docker volume ls --filter label=is-timelord=yes --filter label=is-timelord=no
-
-DRIVER              VOLUME NAME
-```
-
-#### name
-
-The `name` filter matches on all or part of a volume's name.
-
-The following filter matches all volumes with a name containing the `rose` string.
-
-```bash
-$ docker volume ls -f name=rose
-
-DRIVER              VOLUME NAME
-local               rosemary
-```
-
-### Formatting
-
-The formatting options (`--format`) pretty-prints volumes output
-using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-Placeholder   | Description
---------------|------------------------------------------------------------------------------------------
-`.Name`       | Network name
-`.Driver`     | Network driver
-`.Scope`      | Network scope (local, global)
-`.Mountpoint` | Whether the network is internal or not.
-`.Labels`     | All labels assigned to the volume.
-`.Label`      | Value of a specific label for this volume. For example `{{.Label "project.version"}}`
-
-When using the `--format` option, the `volume ls` command will either
-output the data exactly as the template declares or, when using the
-`table` directive, includes column headers as well.
-
-The following example uses a template without headers and outputs the
-`Name` and `Driver` entries separated by a colon for all volumes:
-
-```bash
-$ docker volume ls --format "{{.Name}}: {{.Driver}}"
-
-vol1: local
-vol2: local
-vol3: local
-```

-
-# Glossary
-
-A list of terms used around the Docker project.
-
-## aufs
-
-aufs (advanced multi layered unification filesystem) is a Linux [filesystem](#filesystem) that
-Docker supports as a storage backend. It implements the
-[union mount](http://en.wikipedia.org/wiki/Union_mount) for Linux file systems.
-
-## base image
-
-An image that has no parent is a **base image**.
-
-## boot2docker
-
-[boot2docker](http://boot2docker.io/) is a lightweight Linux distribution made
-specifically to run Docker containers. The boot2docker management tool for Mac and Windows was deprecated and replaced by [`docker-machine`](#machine) which you can install with the Docker Toolbox.
-
-## bridge
-
-In terms of generic networking, a bridge is a Link Layer device which forwards
-traffic between network segments. A bridge can be a hardware device or a
-software device running within a host machine's kernel.
-
-In terms of Docker, a bridge network uses a software bridge which allows
-containers connected to the same bridge network to communicate, while providing
-isolation from containers which are not connected to that bridge network.
-The Docker bridge driver automatically installs rules in the host machine so
-that containers on different bridge networks cannot communicate directly with
-each other.
-
-The default bridge network, which is also named `bridge`, behaves differently
-from user-defined bridge networks. Containers connected to the default `bridge`
-network can communicate with each other across the bridge by IP address but
-cannot resolve each other's container name to an IP address unless they are
-explicitly linked using the `--link` flag to `docker run`.
-
-For more information about Docker networking, see
-[Understand container communication](https://docs.docker.com/engine/userguide/networking/default_network/container-communication/).
-
-## btrfs
-
-btrfs (B-tree file system) is a Linux [filesystem](#filesystem) that Docker
-supports as a storage backend. It is a [copy-on-write](http://en.wikipedia.org/wiki/Copy-on-write)
-filesystem.
-
-## build
-
-build is the process of building Docker images using a [Dockerfile](#dockerfile).
-The build uses a Dockerfile and a "context". The context is the set of files in the
-directory in which the image is built.
-
-## cgroups
-
-cgroups is a Linux kernel feature that limits, accounts for, and isolates
-the resource usage (CPU, memory, disk I/O, network, etc.) of a collection
-of processes. Docker relies on cgroups to control and isolate resource limits.
-
-*Also known as : control groups*
-
-## Compose
-
-[Compose](https://github.com/docker/compose) is a tool for defining and
-running complex applications with Docker. With compose, you define a
-multi-container application in a single file, then spin your
-application up in a single command which does everything that needs to
-be done to get it running.
-
-*Also known as : docker-compose, fig*
-
-## copy-on-write
-
-Docker uses a
-[copy-on-write](https://docs.docker.com/engine/userguide/storagedriver/imagesandcontainers/#/the-copy-on-write-strategy)
-technique and a [union file system](#union-file-system) for both images and
-containers to optimize resources and speed performance. Multiple copies of an
-entity share the same instance and each one makes only specific changes to its
-unique layer.
-
-Multiple containers can share access to the same image, and make
-container-specific changes on a writable layer which is deleted when
-the container is removed. This speeds up container start times and performance.
-
-Images are essentially layers of filesystems typically predicated on a base
-image under a writable layer, and built up with layers of differences from the
-base image. This minimizes the footprint of the image and enables shared
-development.
-
-For more about copy-on-write in the context of Docker, see [Understand images,
-containers, and storage
-drivers](https://docs.docker.com/engine/userguide/storagedriver/imagesandcontainers/).
-
-## container
-
-A container is a runtime instance of a [docker image](#image).
-
-A Docker container consists of
-
-- A Docker image
-- Execution environment
-- A standard set of instructions
-
-The concept is borrowed from Shipping Containers, which define a standard to ship
-goods globally. Docker defines a standard to ship software.
-
-## data volume
-
-A data volume is a specially-designated directory within one or more containers
-that bypasses the Union File System. Data volumes are designed to persist data,
-independent of the container's life cycle. Docker therefore never automatically
-delete volumes when you remove a container, nor will it "garbage collect"
-volumes that are no longer referenced by a container.
-
-
-## Docker
-
-The term Docker can refer to
-
-- The Docker project as a whole, which is a platform for developers and sysadmins to
-develop, ship, and run applications
-- The docker daemon process running on the host which manages images and containers
-
-
-## Docker for Mac
-
-[Docker for Mac](https://docs.docker.com/docker-for-mac/) is an easy-to-install,
-lightweight Docker development environment designed specifically for the Mac. A
-native Mac application, Docker for Mac uses the macOS Hypervisor framework,
-networking, and filesystem. It's the best solution if you want to build, debug,
-test, package, and ship Dockerized applications on a Mac. Docker for Mac
-supersedes [Docker Toolbox](#toolbox) as state-of-the-art Docker on macOS.
-
-
-## Docker for Windows
-
-[Docker for Windows](https://docs.docker.com/docker-for-windows/) is an
-easy-to-install, lightweight Docker development environment designed
-specifically for Windows 10 systems that support Microsoft Hyper-V
-(Professional, Enterprise and Education). Docker for Windows uses Hyper-V for
-virtualization, and runs as a native Windows app. It works with Windows Server
-2016, and gives you the ability to set up and run Windows containers as well as
-the standard Linux containers, with an option to switch between the two. Docker
-for Windows is the best solution if you want to build, debug, test, package, and
-ship Dockerized applications from Windows machines. Docker for Windows
-supersedes [Docker Toolbox](#toolbox) as state-of-the-art Docker on Windows.
-
-## Docker Hub
-
-The [Docker Hub](https://hub.docker.com/) is a centralized resource for working with
-Docker and its components. It provides the following services:
-
-- Docker image hosting
-- User authentication
-- Automated image builds and work-flow tools such as build triggers and web hooks
-- Integration with GitHub and Bitbucket
-
-
-## Dockerfile
-
-A Dockerfile is a text document that contains all the commands you would
-normally execute manually in order to build a Docker image. Docker can
-build images automatically by reading the instructions from a Dockerfile.
-
-## filesystem
-
-A file system is the method an operating system uses to name files
-and assign them locations for efficient storage and retrieval.
-
-Examples :
-
-- Linux : ext4, aufs, btrfs, zfs
-- Windows : NTFS
-- macOS : HFS+
-
-## image
-
-Docker images are the basis of [containers](#container). An Image is an
-ordered collection of root filesystem changes and the corresponding
-execution parameters for use within a container runtime. An image typically
-contains a union of layered filesystems stacked on top of each other. An image
-does not have state and it never changes.
-
-## libcontainer
-
-libcontainer provides a native Go implementation for creating containers with
-namespaces, cgroups, capabilities, and filesystem access controls. It allows
-you to manage the lifecycle of the container performing additional operations
-after the container is created.
-
-## libnetwork
-
-libnetwork provides a native Go implementation for creating and managing container
-network namespaces and other network resources. It manage the networking lifecycle
-of the container performing additional operations after the container is created.
-
-## link
-
-links provide a legacy interface to connect Docker containers running on the
-same host to each other without exposing the hosts' network ports. Use the
-Docker networks feature instead.
-
-## Machine
-
-[Machine](https://github.com/docker/machine) is a Docker tool which
-makes it really easy to create Docker hosts on  your computer, on
-cloud providers and inside your own data center. It creates servers,
-installs Docker on them, then configures the Docker client to talk to them.
-
-*Also known as : docker-machine*
-
-## node
-
-A [node](https://docs.docker.com/engine/swarm/how-swarm-mode-works/nodes/) is a physical or virtual
-machine running an instance of the Docker Engine in swarm mode.
-
-**Manager nodes** perform swarm management and orchestration duties. By default
-manager nodes are also worker nodes.
-
-**Worker nodes** execute tasks.
-
-## overlay network driver
-
-Overlay network driver provides out of the box multi-host network connectivity
-for docker containers in a cluster.
-
-## overlay storage driver
-
-OverlayFS is a [filesystem](#filesystem) service for Linux which implements a
-[union mount](http://en.wikipedia.org/wiki/Union_mount) for other file systems.
-It is supported by the Docker daemon as a storage driver.
-
-## registry
-
-A Registry is a hosted service containing [repositories](#repository) of [images](#image)
-which responds to the Registry API.
-
-The default registry can be accessed using a browser at [Docker Hub](#docker-hub)
-or using the `docker search` command.
-
-## repository
-
-A repository is a set of Docker images. A repository can be shared by pushing it
-to a [registry](#registry) server. The different images in the repository can be
-labeled using [tags](#tag).
-
-Here is an example of the shared [nginx repository](https://hub.docker.com/_/nginx/)
-and its [tags](https://hub.docker.com/r/library/nginx/tags/)
-
-
-## service
-
-A [service](https://docs.docker.com/engine/swarm/how-swarm-mode-works/services/) is the definition of how
-you want to run your application containers in a swarm. At the most basic level
-a service  defines which container image to run in the swarm and which commands
-to run in the container. For orchestration purposes, the service defines the
-"desired state", meaning how many containers to run as tasks and constraints for
-deploying the containers.
-
-Frequently a service is a microservice within the context of some larger
-application. Examples of services might include an HTTP server, a database, or
-any other type of executable program that you wish to run in a distributed
-environment.
-
-## service discovery
-
-Swarm mode [service discovery](https://docs.docker.com/engine/swarm/networking/#use-swarm-mode-service-discovery) is a DNS component
-internal to the swarm that automatically assigns each service on an overlay
-network in the swarm a VIP and DNS entry. Containers on the network share DNS
-mappings for the service via gossip so any container on the network can access
-the service via its service name.
-
-You don’t need to expose service-specific ports to make the service available to
-other services on the same overlay network. The swarm’s internal load balancer
-automatically distributes requests to the service VIP among the active tasks.
-
-## swarm
-
-A [swarm](https://docs.docker.com/engine/swarm/) is a cluster of one or more Docker Engines running in [swarm mode](#swarm-mode).
-
-## Docker Swarm
-
-Do not confuse [Docker Swarm](https://github.com/docker/swarm) with the [swarm mode](#swarm-mode) features in Docker Engine.
-
-Docker Swarm is the name of a standalone native clustering tool for Docker.
-Docker Swarm pools together several Docker hosts and exposes them as a single
-virtual Docker host. It serves the standard Docker API, so any tool that already
-works with Docker can now transparently scale up to multiple hosts.
-
-*Also known as : docker-swarm*
-
-## swarm mode
-
-[Swarm mode](https://docs.docker.com/engine/swarm/) refers to cluster management and orchestration
-features embedded in Docker Engine. When you initialize a new swarm (cluster) or
-join nodes to a swarm, the Docker Engine runs in swarm mode.
-
-## tag
-
-A tag is a label applied to a Docker image in a [repository](#repository).
-tags are how various images in a repository are distinguished from each other.
-
-*Note : This label is not related to the key=value labels set for docker daemon*
-
-## task
-
-A [task](https://docs.docker.com/engine/swarm/how-swarm-mode-works/services/#/tasks-and-scheduling) is the
-atomic unit of scheduling within a swarm. A task carries a Docker container and
-the commands to run inside the container. Manager nodes assign tasks to worker
-nodes according to the number of replicas set in the service scale.
-
-The diagram below illustrates the relationship of services to tasks and
-containers.
-
-![services diagram](https://docs.docker.com/engine/swarm/images/services-diagram.png)
-
-## Toolbox
-
-[Docker Toolbox](https://docs.docker.com/toolbox/overview/) is a legacy
-installer for Mac and Windows users. It uses Oracle VirtualBox for
-virtualization.
-
-For Macs running OS X El Capitan 10.11 and newer macOS releases, [Docker for
-Mac](https://docs.docker.com/docker-for-mac/) is the better solution.
-
-For Windows 10 systems that support Microsoft Hyper-V (Professional, Enterprise
-and Education), [Docker for
-Windows](https://docs.docker.com/docker-for-windows/) is the better solution.
-
-## Union file system
-
-Union file systems implement a [union
-mount](https://en.wikipedia.org/wiki/Union_mount) and operate by creating
-layers. Docker uses union file systems in conjunction with
-[copy-on-write](#copy-on-write) techniques to provide the building blocks for
-containers, making them very lightweight and fast.
-
-For more on Docker and union file systems, see [Docker and AUFS in
-practice](https://docs.docker.com/engine/userguide/storagedriver/aufs-driver/),
-[Docker and Btrfs in
-practice](https://docs.docker.com/engine/userguide/storagedriver/btrfs-driver/),
-and [Docker and OverlayFS in
-practice](https://docs.docker.com/engine/userguide/storagedriver/overlayfs-driver/)
-
-Example implementations of union file systems are
-[UnionFS](https://en.wikipedia.org/wiki/UnionFS),

-## virtual machine
-
-A virtual machine is a program that emulates a complete computer and imitates dedicated hardware.
-It shares physical hardware resources with other users but isolates the operating system. The
-end user has the same experience on a Virtual Machine as they would have on dedicated hardware.
-
-Compared to containers, a virtual machine is heavier to run, provides more isolation,
-gets its own set of resources and does minimal sharing.

-# Docker run reference
-
-Docker runs processes in isolated containers. A container is a process
-which runs on a host. The host may be local or remote. When an operator
-executes `docker run`, the container process that runs is isolated in
-that it has its own file system, its own networking, and its own
-isolated process tree separate from the host.
-
-This page details how to use the `docker run` command to define the
-container's resources at runtime.
-
-## General form
-
-The basic `docker run` command takes this form:
-
-    $ docker run [OPTIONS] IMAGE[:TAG|@DIGEST] [COMMAND] [ARG...]
-
-The `docker run` command must specify an [*IMAGE*](glossary.md#image)
-to derive the container from. An image developer can define image
-defaults related to:
-
- * detached or foreground running
- * container identification
- * network settings
- * runtime constraints on CPU and memory
-
-With the `docker run [OPTIONS]` an operator can add to or override the
-image defaults set by a developer. And, additionally, operators can
-override nearly all the defaults set by the Docker runtime itself. The
-operator's ability to override image and Docker runtime defaults is why
-[*run*](commandline/run.md) has more options than any
-other `docker` command.
-
-To learn how to interpret the types of `[OPTIONS]`, see [*Option
-types*](commandline/cli.md#option-types).
-
-> **Note**: Depending on your Docker system configuration, you may be
-> required to preface the `docker run` command with `sudo`. To avoid
-> having to use `sudo` with the `docker` command, your system
-> administrator can create a Unix group called `docker` and add users to
-> it. For more information about this configuration, refer to the Docker
-> installation documentation for your operating system.
-
-
-## Operator exclusive options
-
-Only the operator (the person executing `docker run`) can set the
-following options.
-
- - [Detached vs foreground](#detached-vs-foreground)
-     - [Detached (-d)](#detached--d)
-     - [Foreground](#foreground)
- - [Container identification](#container-identification)
-     - [Name (--name)](#name---name)
-     - [PID equivalent](#pid-equivalent)
- - [IPC settings (--ipc)](#ipc-settings---ipc)
- - [Network settings](#network-settings)
- - [Restart policies (--restart)](#restart-policies---restart)
- - [Clean up (--rm)](#clean-up---rm)
- - [Runtime constraints on resources](#runtime-constraints-on-resources)
- - [Runtime privilege and Linux capabilities](#runtime-privilege-and-linux-capabilities)
-
-## Detached vs foreground
-
-When starting a Docker container, you must first decide if you want to
-run the container in the background in a "detached" mode or in the
-default foreground mode:
-
-    -d=false: Detached mode: Run container in the background, print new container id
-
-### Detached (-d)
-
-To start a container in detached mode, you use `-d=true` or just `-d` option. By
-design, containers started in detached mode exit when the root process used to
-run the container exits. A container in detached mode cannot be automatically
-removed when it stops, this means you cannot use the `--rm` option with `-d` option.
-
-Do not pass a `service x start` command to a detached container. For example, this
-command attempts to start the `nginx` service.
-
-    $ docker run -d -p 80:80 my_image service nginx start
-
-This succeeds in starting the `nginx` service inside the container. However, it
-fails the detached container paradigm in that, the root process (`service nginx
-start`) returns and the detached container stops as designed. As a result, the
-`nginx` service is started but could not be used. Instead, to start a process
-such as the `nginx` web server do the following:
-
-    $ docker run -d -p 80:80 my_image nginx -g 'daemon off;'
-
-To do input/output with a detached container use network connections or shared
-volumes. These are required because the container is no longer listening to the
-command line where `docker run` was run.
-
-To reattach to a detached container, use `docker`
-[*attach*](commandline/attach.md) command.
-
-### Foreground
-
-In foreground mode (the default when `-d` is not specified), `docker
-run` can start the process in the container and attach the console to
-the process's standard input, output, and standard error. It can even
-pretend to be a TTY (this is what most command line executables expect)
-and pass along signals. All of that is configurable:
-
-    -a=[]           : Attach to `STDIN`, `STDOUT` and/or `STDERR`
-    -t              : Allocate a pseudo-tty
-    --sig-proxy=true: Proxy all received signals to the process (non-TTY mode only)
-    -i              : Keep STDIN open even if not attached
-
-If you do not specify `-a` then Docker will [attach to both stdout and stderr
-]( https://github.com/docker/docker/blob/4118e0c9eebda2412a09ae66e90c34b85fae3275/runconfig/opts/parse.go#L267).
-You can specify to which of the three standard streams (`STDIN`, `STDOUT`,
-`STDERR`) you'd like to connect instead, as in:
-
-    $ docker run -a stdin -a stdout -i -t ubuntu /bin/bash
-
-For interactive processes (like a shell), you must use `-i -t` together in
-order to allocate a tty for the container process. `-i -t` is often written `-it`
-as you'll see in later examples.  Specifying `-t` is forbidden when the client
-is receiving its standard input from a pipe, as in:
-
-    $ echo test | docker run -i busybox cat
-
->**Note**: A process running as PID 1 inside a container is treated
->specially by Linux: it ignores any signal with the default action.
->So, the process will not terminate on `SIGINT` or `SIGTERM` unless it is
->coded to do so.
-
-## Container identification
-
-### Name (--name)
-
-The operator can identify a container in three ways:
-
-| Identifier type       | Example value                                                      |
-| --------------------- | ------------------------------------------------------------------ |
-| UUID long identifier  | "f78375b1c487e03c9438c729345e54db9d20cfa2ac1fc3494b6eb60872e74778" |
-| UUID short identifier | "f78375b1c487"                                                     |
-| Name                  | "evil_ptolemy"                                                     |
-
-The UUID identifiers come from the Docker daemon. If you do not assign a
-container name with the `--name` option, then the daemon generates a random
-string name for you. Defining a `name` can be a handy way to add meaning to a
-container. If you specify a `name`, you can use it  when referencing the
-container within a Docker network. This works for both background and foreground
-Docker containers.
-
-> **Note**: Containers on the default bridge network must be linked to
-> communicate by name.
-
-### PID equivalent
-
-Finally, to help with automation, you can have Docker write the
-container ID out to a file of your choosing. This is similar to how some
-programs might write out their process ID to a file (you've seen them as
-PID files):
-
-    --cidfile="": Write the container ID to the file
-
-### Image[:tag]
-
-While not strictly a means of identifying a container, you can specify a version of an
-image you'd like to run the container with by adding `image[:tag]` to the command. For
-example, `docker run ubuntu:14.04`.
-
-### Image[@digest]
-
-Images using the v2 or later image format have a content-addressable identifier
-called a digest. As long as the input used to generate the image is unchanged,
-the digest value is predictable and referenceable.
-
-The following example runs a container from the `alpine` image with the
-`sha256:9cacb71397b640eca97488cf08582ae4e4068513101088e9f96c9814bfda95e0` digest:
-
-    $ docker run alpine@sha256:9cacb71397b640eca97488cf08582ae4e4068513101088e9f96c9814bfda95e0 date
-
-## PID settings (--pid)
-
-    --pid=""  : Set the PID (Process) Namespace mode for the container,
-                 'container:<name|id>': joins another container's PID namespace
-                 'host': use the host's PID namespace inside the container
-
-By default, all containers have the PID namespace enabled.
-
-PID namespace provides separation of processes. The PID Namespace removes the
-view of the system processes, and allows process ids to be reused including
-pid 1.
-
-In certain cases you want your container to share the host's process namespace,
-basically allowing processes within the container to see all of the processes
-on the system.  For example, you could build a container with debugging tools
-like `strace` or `gdb`, but want to use these tools when debugging processes
-within the container.
-
-### Example: run htop inside a container
-
-Create this Dockerfile:
-
-```
-FROM alpine:latest
-RUN apk add --update htop && rm -rf /var/cache/apk/*
-CMD ["htop"]
-```
-
-Build the Dockerfile and tag the image as `myhtop`:
-
-```bash
-$ docker build -t myhtop .
-```
-
-Use the following command to run `htop` inside a container:
-
-```
-$ docker run -it --rm --pid=host myhtop
-```
-
-Joining another container's pid namespace can be used for debugging that container.
-
-### Example
-
-Start a container running a redis server:
-
-```bash
-$ docker run --name my-redis -d redis
-```
-
-Debug the redis container by running another container that has strace in it:
-
-```bash
-$ docker run -it --pid=container:my-redis my_strace_docker_image bash
-$ strace -p 1
-```
-
-## UTS settings (--uts)
-
-    --uts=""  : Set the UTS namespace mode for the container,
-           'host': use the host's UTS namespace inside the container
-
-The UTS namespace is for setting the hostname and the domain that is visible
-to running processes in that namespace.  By default, all containers, including
-those with `--network=host`, have their own UTS namespace.  The `host` setting will
-result in the container using the same UTS namespace as the host.  Note that
-`--hostname` is invalid in `host` UTS mode.
-
-You may wish to share the UTS namespace with the host if you would like the
-hostname of the container to change as the hostname of the host changes.  A
-more advanced use case would be changing the host's hostname from a container.
-
-## IPC settings (--ipc)
-
-    --ipc=""  : Set the IPC mode for the container,
-                 'container:<name|id>': reuses another container's IPC namespace
-                 'host': use the host's IPC namespace inside the container
-
-By default, all containers have the IPC namespace enabled.
-
-IPC (POSIX/SysV IPC) namespace provides separation of named shared memory
-segments, semaphores and message queues.
-
-Shared memory segments are used to accelerate inter-process communication at
-memory speed, rather than through pipes or through the network stack. Shared
-memory is commonly used by databases and custom-built (typically C/OpenMPI,
-C++/using boost libraries) high performance applications for scientific
-computing and financial services industries. If these types of applications
-are broken into multiple containers, you might need to share the IPC mechanisms
-of the containers.
-
-## Network settings
-
-    --dns=[]           : Set custom dns servers for the container
-    --network="bridge" : Connect a container to a network
-                          'bridge': create a network stack on the default Docker bridge
-                          'none': no networking
-                          'container:<name|id>': reuse another container's network stack
-                          'host': use the Docker host network stack
-                          '<network-name>|<network-id>': connect to a user-defined network
-    --network-alias=[] : Add network-scoped alias for the container
-    --add-host=""      : Add a line to /etc/hosts (host:IP)
-    --mac-address=""   : Sets the container's Ethernet device's MAC address
-    --ip=""            : Sets the container's Ethernet device's IPv4 address
-    --ip6=""           : Sets the container's Ethernet device's IPv6 address
-    --link-local-ip=[] : Sets one or more container's Ethernet device's link local IPv4/IPv6 addresses
-
-By default, all containers have networking enabled and they can make any
-outgoing connections. The operator can completely disable networking
-with `docker run --network none` which disables all incoming and outgoing
-networking. In cases like this, you would perform I/O through files or
-`STDIN` and `STDOUT` only.
-
-Publishing ports and linking to other containers only works with the default (bridge). The linking feature is a legacy feature. You should always prefer using Docker network drivers over linking.
-
-Your container will use the same DNS servers as the host by default, but
-you can override this with `--dns`.
-
-By default, the MAC address is generated using the IP address allocated to the
-container. You can set the container's MAC address explicitly by providing a
-MAC address via the `--mac-address` parameter (format:`12:34:56:78:9a:bc`).Be
-aware that Docker does not check if manually specified MAC addresses are unique.

-</table>
-
-#### Network: none
-
-With the network is `none` a container will not have
-access to any external routes.  The container will still have a
-`loopback` interface enabled in the container but it does not have any
-routes to external traffic.
-
-#### Network: bridge
-
-With the network set to `bridge` a container will use docker's
-default networking setup.  A bridge is setup on the host, commonly named
-`docker0`, and a pair of `veth` interfaces will be created for the
-container.  One side of the `veth` pair will remain on the host attached
-to the bridge while the other side of the pair will be placed inside the
-container's namespaces in addition to the `loopback` interface.  An IP
-address will be allocated for containers on the bridge's network and
-traffic will be routed though this bridge to the container.
-
-Containers can communicate via their IP addresses by default. To communicate by
-name, they must be linked.
-
-#### Network: host
-
-With the network set to `host` a container will share the host's
-network stack and all interfaces from the host will be available to the
-container.  The container's hostname will match the hostname on the host
-system. Note that `--mac-address` is invalid in `host` netmode. Even in `host`
-network mode a container has its own UTS namespace by default. As such
-`--hostname` is allowed in `host` network mode and will only change the
-hostname inside the container.
-Similar to `--hostname`, the `--add-host`, `--dns`, `--dns-search`, and
-`--dns-option` options can be used in `host` network mode. These options update
-`/etc/hosts` or `/etc/resolv.conf` inside the container. No change are made to
-`/etc/hosts` and `/etc/resolv.conf` on the host.
-
-Compared to the default `bridge` mode, the `host` mode gives *significantly*
-better networking performance since it uses the host's native networking stack
-whereas the bridge has to go through one level of virtualization through the
-docker daemon. It is recommended to run containers in this mode when their
-networking performance is critical, for example, a production Load Balancer
-or a High Performance Web Server.
-
-> **Note**: `--network="host"` gives the container full access to local system
-> services such as D-bus and is therefore considered insecure.
-
-#### Network: container
-
-With the network set to `container` a container will share the
-network stack of another container.  The other container's name must be
-provided in the format of `--network container:<name|id>`. Note that `--add-host`
-`--hostname` `--dns` `--dns-search` `--dns-option` and `--mac-address` are
-invalid in `container` netmode, and `--publish` `--publish-all` `--expose` are
-also invalid in `container` netmode.
-
-Example running a Redis container with Redis binding to `localhost` then
-running the `redis-cli` command and connecting to the Redis server over the
-`localhost` interface.
-
-    $ docker run -d --name redis example/redis --bind 127.0.0.1
-    $ # use the redis container's network stack to access localhost
-    $ docker run --rm -it --network container:redis example/redis-cli -h 127.0.0.1
-
-#### User-defined network
-
-You can create a network using a Docker network driver or an external network
-driver plugin. You can connect multiple containers to the same network. Once
-connected to a user-defined network, the containers can communicate easily using
-only another container's IP address or name.
-
-For `overlay` networks or custom plugins that support multi-host connectivity,
-containers connected to the same multi-host network but launched from different
-Engines can also communicate in this way.
-
-The following example creates a network using the built-in `bridge` network
-driver and running a container in the created network
-
-```
-$ docker network create -d bridge my-net
-$ docker run --network=my-net -itd --name=container3 busybox
-```
-
-### Managing /etc/hosts
-
-Your container will have lines in `/etc/hosts` which define the hostname of the
-container itself as well as `localhost` and a few other common things. The
-`--add-host` flag can be used to add additional lines to `/etc/hosts`.
-
-    $ docker run -it --add-host db-static:86.75.30.9 ubuntu cat /etc/hosts
-    172.17.0.22     09d03f76bf2c
-    fe00::0         ip6-localnet
-    ff00::0         ip6-mcastprefix
-    ff02::1         ip6-allnodes
-    ff02::2         ip6-allrouters
-    127.0.0.1       localhost
-    ::1	            localhost ip6-localhost ip6-loopback
-    86.75.30.9      db-static
-
-If a container is connected to the default bridge network and `linked`
-with other containers, then the container's `/etc/hosts` file is updated
-with the linked container's name.
-
-> **Note** Since Docker may live update the container’s `/etc/hosts` file, there
-may be situations when processes inside the container can end up reading an
-empty or incomplete `/etc/hosts` file. In most cases, retrying the read again
-should fix the problem.
-
-## Restart policies (--restart)
-
-Using the `--restart` flag on Docker run you can specify a restart policy for
-how a container should or should not be restarted on exit.
-
-When a restart policy is active on a container, it will be shown as either `Up`
-or `Restarting` in [`docker ps`](commandline/ps.md). It can also be
-useful to use [`docker events`](commandline/events.md) to see the
-restart policy in effect.
-
-Docker supports the following restart policies:
-
-<table>
-  <thead>
-    <tr>
-      <th>Policy</th>
-      <th>Result</th>
-    </tr>
-  </thead>
-  <tbody>
-    <tr>
-      <td><strong>no</strong></td>
-      <td>
-        Do not automatically restart the container when it exits. This is the
-        default.
-      </td>
-    </tr>
-    <tr>
-      <td>
-        <span style="white-space: nowrap">
-          <strong>on-failure</strong>[:max-retries]
-        </span>
-      </td>
-      <td>
-        Restart only if the container exits with a non-zero exit status.
-        Optionally, limit the number of restart retries the Docker
-        daemon attempts.
-      </td>
-    </tr>
-    <tr>
-      <td><strong>always</strong></td>
-      <td>
-        Always restart the container regardless of the exit status.
-        When you specify always, the Docker daemon will try to restart
-        the container indefinitely. The container will also always start
-        on daemon startup, regardless of the current state of the container.
-      </td>
-    </tr>
-    <tr>
-      <td><strong>unless-stopped</strong></td>
-      <td>
-        Always restart the container regardless of the exit status, but
-        do not start it on daemon startup if the container has been put
-        to a stopped state before.
-      </td>
-    </tr>
-  </tbody>
-</table>
-
-An ever increasing delay (double the previous delay, starting at 100
-milliseconds) is added before each restart to prevent flooding the server.
-This means the daemon will wait for 100 ms, then 200 ms, 400, 800, 1600,
-and so on until either the `on-failure` limit is hit, or when you `docker stop`
-or `docker rm -f` the container.
-
-If a container is successfully restarted (the container is started and runs
-for at least 10 seconds), the delay is reset to its default value of 100 ms.
-
-You can specify the maximum amount of times Docker will try to restart the
-container when using the **on-failure** policy.  The default is that Docker
-will try forever to restart the container. The number of (attempted) restarts
-for a container can be obtained via [`docker inspect`](commandline/inspect.md). For example, to get the number of restarts
-for container "my-container";
-
-    {% raw %}
-    $ docker inspect -f "{{ .RestartCount }}" my-container
-    # 2
-    {% endraw %}
-
-Or, to get the last time the container was (re)started;
-
-    {% raw %}
-    $ docker inspect -f "{{ .State.StartedAt }}" my-container
-    # 2015-03-04T23:47:07.691840179Z
-    {% endraw %}
-
-
-Combining `--restart` (restart policy) with the `--rm` (clean up) flag results
-in an error. On container restart, attached clients are disconnected. See the
-examples on using the [`--rm` (clean up)](#clean-up-rm) flag later in this page.
-
-### Examples
-
-    $ docker run --restart=always redis
-
-This will run the `redis` container with a restart policy of **always**
-so that if the container exits, Docker will restart it.
-
-    $ docker run --restart=on-failure:10 redis
-
-This will run the `redis` container with a restart policy of **on-failure**
-and a maximum restart count of 10.  If the `redis` container exits with a
-non-zero exit status more than 10 times in a row Docker will abort trying to
-restart the container. Providing a maximum restart limit is only valid for the
-**on-failure** policy.
-
-## Exit Status
-
-The exit code from `docker run` gives information about why the container
-failed to run or why it exited.  When `docker run` exits with a non-zero code,
-the exit codes follow the `chroot` standard, see below:
-
-**_125_** if the error is with Docker daemon **_itself_**
-
-    $ docker run --foo busybox; echo $?
-    # flag provided but not defined: --foo
-      See 'docker run --help'.
-      125
-
-**_126_** if the **_contained command_** cannot be invoked
-
-    $ docker run busybox /etc; echo $?
-    # docker: Error response from daemon: Container command '/etc' could not be invoked.
-      126
-
-**_127_** if the **_contained command_** cannot be found
-
-    $ docker run busybox foo; echo $?
-    # docker: Error response from daemon: Container command 'foo' not found or does not exist.
-      127
-
-**_Exit code_** of **_contained command_** otherwise
-
-    $ docker run busybox /bin/sh -c 'exit 3'; echo $?
-    # 3
-
-## Clean up (--rm)
-
-By default a container's file system persists even after the container
-exits. This makes debugging a lot easier (since you can inspect the
-final state) and you retain all your data by default. But if you are
-running short-term **foreground** processes, these container file
-systems can really pile up. If instead you'd like Docker to
-**automatically clean up the container and remove the file system when
-the container exits**, you can add the `--rm` flag:
-
-    --rm=false: Automatically remove the container when it exits (incompatible with -d)
-
-> **Note**: When you set the `--rm` flag, Docker also removes the volumes
-associated with the container when the container is removed. This is similar
-to running `docker rm -v my-container`. Only volumes that are specified without a
-name are removed. For example, with
-`docker run --rm -v /foo -v awesome:/bar busybox top`, the volume for `/foo` will be removed,
-but the volume for `/bar` will not. Volumes inherited via `--volumes-from` will be removed
-with the same logic -- if the original volume was specified with a name it will **not** be removed.
-
-## Security configuration
-    --security-opt="label=user:USER"     : Set the label user for the container
-    --security-opt="label=role:ROLE"     : Set the label role for the container
-    --security-opt="label=type:TYPE"     : Set the label type for the container
-    --security-opt="label=level:LEVEL"   : Set the label level for the container
-    --security-opt="label=disable"       : Turn off label confinement for the container
-    --security-opt="apparmor=PROFILE"    : Set the apparmor profile to be applied to the container
-    --security-opt="no-new-privileges:true|false"   : Disable/enable container processes from gaining new privileges
-    --security-opt="seccomp=unconfined"  : Turn off seccomp confinement for the container
-    --security-opt="seccomp=profile.json": White listed syscalls seccomp Json file to be used as a seccomp filter
-
-
-You can override the default labeling scheme for each container by specifying
-the `--security-opt` flag. Specifying the level in the following command
-allows you to share the same content between containers.
-
-    $ docker run --security-opt label=level:s0:c100,c200 -it fedora bash
-
-> **Note**: Automatic translation of MLS labels is not currently supported.
-
-To disable the security labeling for this container versus running with the
-`--privileged` flag, use the following command:
-
-    $ docker run --security-opt label=disable -it fedora bash
-
-If you want a tighter security policy on the processes within a container,
-you can specify an alternate type for the container. You could run a container
-that is only allowed to listen on Apache ports by executing the following
-command:
-
-    $ docker run --security-opt label=type:svirt_apache_t -it centos bash
-
-> **Note**: You would have to write policy defining a `svirt_apache_t` type.
-
-If you want to prevent your container processes from gaining additional
-privileges, you can execute the following command:
-
-    $ docker run --security-opt no-new-privileges -it centos bash
-
-This means that commands that raise privileges such as `su` or `sudo` will no longer work.
-It also causes any seccomp filters to be applied later, after privileges have been dropped
-which may mean you can have a more restrictive set of filters.
-For more details, see the [kernel documentation](https://www.kernel.org/doc/Documentation/prctl/no_new_privs.txt).
-
-## Specify an init process
-
-You can use the `--init` flag to indicate that an init process should be used as
-the PID 1 in the container. Specifying an init process ensures the usual
-responsibilities of an init system, such as reaping zombie processes, are
-performed inside the created container.
-
-The default init process used is the first `docker-init` executable found in the
-system path of the Docker daemon process. This `docker-init` binary, included in
-the default installation, is backed by [tini](https://github.com/krallin/tini).
-
-## Specify custom cgroups
-
-Using the `--cgroup-parent` flag, you can pass a specific cgroup to run a
-container in. This allows you to create and manage cgroups on their own. You can
-define custom resources for those cgroups and put containers under a common
-parent group.
-
-## Runtime constraints on resources
-
-The operator can also adjust the performance parameters of the
-container:
-
-| Option                     |  Description                                                                                                                                    |

-| `--blkio-weight-device=""` | Block IO weight (relative device weight, format: `DEVICE_NAME:WEIGHT`)                                                                          |

-### User memory constraints
-
-We have four ways to set user memory usage:
-
-<table>
-  <thead>
-    <tr>
-      <th>Option</th>
-      <th>Result</th>
-    </tr>
-  </thead>
-  <tbody>
-    <tr>
-      <td class="no-wrap">
-          <strong>memory=inf, memory-swap=inf</strong> (default)
-      </td>
-      <td>
-        There is no memory limit for the container. The container can use
-        as much memory as needed.
-      </td>
-    </tr>
-    <tr>
-      <td class="no-wrap"><strong>memory=L&lt;inf, memory-swap=inf</strong></td>
-      <td>
-        (specify memory and set memory-swap as <code>-1</code>) The container is
-        not allowed to use more than L bytes of memory, but can use as much swap
-        as is needed (if the host supports swap memory).
-      </td>
-    </tr>
-    <tr>
-      <td class="no-wrap"><strong>memory=L&lt;inf, memory-swap=2*L</strong></td>
-      <td>
-        (specify memory without memory-swap) The container is not allowed to
-        use more than L bytes of memory, swap <i>plus</i> memory usage is double
-        of that.
-      </td>
-    </tr>
-    <tr>
-      <td class="no-wrap">
-          <strong>memory=L&lt;inf, memory-swap=S&lt;inf, L&lt;=S</strong>
-      </td>
-      <td>
-        (specify both memory and memory-swap) The container is not allowed to
-        use more than L bytes of memory, swap <i>plus</i> memory usage is limited
-        by S.
-      </td>
-    </tr>
-  </tbody>
-</table>
-
-Examples:
-
-    $ docker run -it ubuntu:14.04 /bin/bash
-
-We set nothing about memory, this means the processes in the container can use
-as much memory and swap memory as they need.
-
-    $ docker run -it -m 300M --memory-swap -1 ubuntu:14.04 /bin/bash
-
-We set memory limit and disabled swap memory limit, this means the processes in
-the container can use 300M memory and as much swap memory as they need (if the
-host supports swap memory).
-
-    $ docker run -it -m 300M ubuntu:14.04 /bin/bash
-
-We set memory limit only, this means the processes in the container can use
-300M memory and 300M swap memory, by default, the total virtual memory size
-(--memory-swap) will be set as double of memory, in this case, memory + swap
-would be 2*300M, so processes can use 300M swap memory as well.
-
-    $ docker run -it -m 300M --memory-swap 1G ubuntu:14.04 /bin/bash
-
-We set both memory and swap memory, so the processes in the container can use
-300M memory and 700M swap memory.
-
-Memory reservation is a kind of memory soft limit that allows for greater
-sharing of memory. Under normal circumstances, containers can use as much of
-the memory as needed and are constrained only by the hard limits set with the
-`-m`/`--memory` option. When memory reservation is set, Docker detects memory
-contention or low memory and forces containers to restrict their consumption to
-a reservation limit.
-
-Always set the memory reservation value below the hard limit, otherwise the hard
-limit takes precedence. A reservation of 0 is the same as setting no
-reservation. By default (without reservation set), memory reservation is the
-same as the hard memory limit.
-
-Memory reservation is a soft-limit feature and does not guarantee the limit
-won't be exceeded. Instead, the feature attempts to ensure that, when memory is
-heavily contended for, memory is allocated based on the reservation hints/setup.
-
-The following example limits the memory (`-m`) to 500M and sets the memory
-reservation to 200M.
-
-```bash
-$ docker run -it -m 500M --memory-reservation 200M ubuntu:14.04 /bin/bash
-```
-
-Under this configuration, when the container consumes memory more than 200M and
-less than 500M, the next system memory reclaim attempts to shrink container
-memory below 200M.
-
-The following example set memory reservation to 1G without a hard memory limit.
-
-```bash
-$ docker run -it --memory-reservation 1G ubuntu:14.04 /bin/bash
-```
-
-The container can use as much memory as it needs. The memory reservation setting
-ensures the container doesn't consume too much memory for long time, because
-every memory reclaim shrinks the container's consumption to the reservation.
-
-By default, kernel kills processes in a container if an out-of-memory (OOM)
-error occurs. To change this behaviour, use the `--oom-kill-disable` option.
-Only disable the OOM killer on containers where you have also set the
-`-m/--memory` option. If the `-m` flag is not set, this can result in the host
-running out of memory and require killing the host's system processes to free
-memory.
-
-The following example limits the memory to 100M and disables the OOM killer for
-this container:
-
-    $ docker run -it -m 100M --oom-kill-disable ubuntu:14.04 /bin/bash
-
-The following example, illustrates a dangerous way to use the flag:
-
-    $ docker run -it --oom-kill-disable ubuntu:14.04 /bin/bash
-
-The container has unlimited memory which can cause the host to run out memory
-and require killing system processes to free memory. The `--oom-score-adj`
-parameter can be changed to select the priority of which containers will
-be killed when the system is out of memory, with negative scores making them
-less likely to be killed, and positive scores more likely.
-
-### Kernel memory constraints
-
-Kernel memory is fundamentally different than user memory as kernel memory can't
-be swapped out. The inability to swap makes it possible for the container to
-block system services by consuming too much kernel memory. Kernel memory includes：
-
- - stack pages
- - slab pages
- - sockets memory pressure
- - tcp memory pressure
-
-You can setup kernel memory limit to constrain these kinds of memory. For example,
-every process consumes some stack pages. By limiting kernel memory, you can
-prevent new processes from being created when the kernel memory usage is too high.
-
-Kernel memory is never completely independent of user memory. Instead, you limit
-kernel memory in the context of the user memory limit. Assume "U" is the user memory
-limit and "K" the kernel limit. There are three possible ways to set limits:
-
-<table>
-  <thead>
-    <tr>
-      <th>Option</th>
-      <th>Result</th>
-    </tr>
-  </thead>
-  <tbody>
-    <tr>
-      <td class="no-wrap"><strong>U != 0, K = inf</strong> (default)</td>
-      <td>
-        This is the standard memory limitation mechanism already present before using
-        kernel memory. Kernel memory is completely ignored.
-      </td>
-    </tr>
-    <tr>
-      <td class="no-wrap"><strong>U != 0, K &lt; U</strong></td>
-      <td>
-        Kernel memory is a subset of the user memory. This setup is useful in
-        deployments where the total amount of memory per-cgroup is overcommitted.
-        Overcommitting kernel memory limits is definitely not recommended, since the
-        box can still run out of non-reclaimable memory.
-        In this case, you can configure K so that the sum of all groups is
-        never greater than the total memory. Then, freely set U at the expense of
-        the system's service quality.
-      </td>
-    </tr>
-    <tr>
-      <td class="no-wrap"><strong>U != 0, K &gt; U</strong></td>
-      <td>
-        Since kernel memory charges are also fed to the user counter and reclamation
-        is triggered for the container for both kinds of memory. This configuration
-        gives the admin a unified view of memory. It is also useful for people
-        who just want to track kernel memory usage.
-      </td>
-    </tr>
-  </tbody>
-</table>
-
-Examples:
-
-    $ docker run -it -m 500M --kernel-memory 50M ubuntu:14.04 /bin/bash
-
-We set memory and kernel memory, so the processes in the container can use
-500M memory in total, in this 500M memory, it can be 50M kernel memory tops.
-
-    $ docker run -it --kernel-memory 50M ubuntu:14.04 /bin/bash
-
-We set kernel memory without **-m**, so the processes in the container can
-use as much memory as they want, but they can only use 50M kernel memory.
-
-### Swappiness constraint
-
-By default, a container's kernel can swap out a percentage of anonymous pages.
-To set this percentage for a container, specify a `--memory-swappiness` value
-between 0 and 100. A value of 0 turns off anonymous page swapping. A value of
-100 sets all anonymous pages as swappable. By default, if you are not using
-`--memory-swappiness`, memory swappiness value will be inherited from the parent.
-
-For example, you can set:
-
-    $ docker run -it --memory-swappiness=0 ubuntu:14.04 /bin/bash
-
-Setting the `--memory-swappiness` option is helpful when you want to retain the
-container's working set and to avoid swapping performance penalties.
-
-### CPU share constraint
-
-By default, all containers get the same proportion of CPU cycles. This proportion
-can be modified by changing the container's CPU share weighting relative
-to the weighting of all other running containers.
-
-To modify the proportion from the default of 1024, use the `-c` or `--cpu-shares`
-flag to set the weighting to 2 or higher. If 0 is set, the system will ignore the
-value and use the default of 1024.
-
-The proportion will only apply when CPU-intensive processes are running.
-When tasks in one container are idle, other containers can use the
-left-over CPU time. The actual amount of CPU time will vary depending on
-the number of containers running on the system.
-
-For example, consider three containers, one has a cpu-share of 1024 and
-two others have a cpu-share setting of 512. When processes in all three
-containers attempt to use 100% of CPU, the first container would receive
-50% of the total CPU time. If you add a fourth container with a cpu-share
-of 1024, the first container only gets 33% of the CPU. The remaining containers
-receive 16.5%, 16.5% and 33% of the CPU.
-
-On a multi-core system, the shares of CPU time are distributed over all CPU
-cores. Even if a container is limited to less than 100% of CPU time, it can
-use 100% of each individual CPU core.
-
-For example, consider a system with more than three cores. If you start one
-container `{C0}` with `-c=512` running one process, and another container
-`{C1}` with `-c=1024` running two processes, this can result in the following
-division of CPU shares:
-
-    PID    container	CPU	CPU share
-    100    {C0}		0	100% of CPU0
-    101    {C1}		1	100% of CPU1
-    102    {C1}		2	100% of CPU2
-
-### CPU period constraint
-
-The default CPU CFS (Completely Fair Scheduler) period is 100ms. We can use
-`--cpu-period` to set the period of CPUs to limit the container's CPU usage.
-And usually `--cpu-period` should work with `--cpu-quota`.
-
-Examples:
-
-    $ docker run -it --cpu-period=50000 --cpu-quota=25000 ubuntu:14.04 /bin/bash
-
-If there is 1 CPU, this means the container can get 50% CPU worth of run-time every 50ms.
-
-In addition to use `--cpu-period` and `--cpu-quota` for setting CPU period constraints,
-it is possible to specify `--cpus` with a float number to achieve the same purpose.
-For example, if there is 1 CPU, then `--cpus=0.5` will achieve the same result as
-setting `--cpu-period=50000` and `--cpu-quota=25000` (50% CPU).
-
-The default value for `--cpus` is `0.000`, which means there is no limit.
-
-For more information, see the [CFS documentation on bandwidth limiting](https://www.kernel.org/doc/Documentation/scheduler/sched-bwc.txt).
-
-### Cpuset constraint
-
-We can set cpus in which to allow execution for containers.
-
-Examples:
-
-    $ docker run -it --cpuset-cpus="1,3" ubuntu:14.04 /bin/bash
-
-This means processes in container can be executed on cpu 1 and cpu 3.
-
-    $ docker run -it --cpuset-cpus="0-2" ubuntu:14.04 /bin/bash
-
-This means processes in container can be executed on cpu 0, cpu 1 and cpu 2.
-
-We can set mems in which to allow execution for containers. Only effective
-on NUMA systems.
-
-Examples:
-
-    $ docker run -it --cpuset-mems="1,3" ubuntu:14.04 /bin/bash
-
-This example restricts the processes in the container to only use memory from
-memory nodes 1 and 3.
-
-    $ docker run -it --cpuset-mems="0-2" ubuntu:14.04 /bin/bash
-
-This example restricts the processes in the container to only use memory from
-memory nodes 0, 1 and 2.
-
-### CPU quota constraint
-
-The `--cpu-quota` flag limits the container's CPU usage. The default 0 value
-allows the container to take 100% of a CPU resource (1 CPU). The CFS (Completely Fair
-Scheduler) handles resource allocation for executing processes and is default
-Linux Scheduler used by the kernel. Set this value to 50000 to limit the container
-to 50% of a CPU resource. For multiple CPUs, adjust the `--cpu-quota` as necessary.
-For more information, see the [CFS documentation on bandwidth limiting](https://www.kernel.org/doc/Documentation/scheduler/sched-bwc.txt).
-
-### Block IO bandwidth (Blkio) constraint
-
-By default, all containers get the same proportion of block IO bandwidth
-(blkio). This proportion is 500. To modify this proportion, change the
-container's blkio weight relative to the weighting of all other running
-containers using the `--blkio-weight` flag.
-
-> **Note:** The blkio weight setting is only available for direct IO. Buffered IO
-> is not currently supported.
-
-The `--blkio-weight` flag can set the weighting to a value between 10 to 1000.
-For example, the commands below create two containers with different blkio
-weight:
-
-    $ docker run -it --name c1 --blkio-weight 300 ubuntu:14.04 /bin/bash
-    $ docker run -it --name c2 --blkio-weight 600 ubuntu:14.04 /bin/bash
-
-If you do block IO in the two containers at the same time, by, for example:
-
-    $ time dd if=/mnt/zerofile of=test.out bs=1M count=1024 oflag=direct
-
-You'll find that the proportion of time is the same as the proportion of blkio
-weights of the two containers.
-
-The `--blkio-weight-device="DEVICE_NAME:WEIGHT"` flag sets a specific device weight.
-The `DEVICE_NAME:WEIGHT` is a string containing a colon-separated device name and weight.
-For example, to set `/dev/sda` device weight to `200`:
-
-    $ docker run -it \
-        --blkio-weight-device "/dev/sda:200" \
-        ubuntu
-
-If you specify both the `--blkio-weight` and `--blkio-weight-device`, Docker
-uses the `--blkio-weight` as the default weight and uses `--blkio-weight-device`
-to override this default with a new value on a specific device.
-The following example uses a default weight of `300` and overrides this default
-on `/dev/sda` setting that weight to `200`:
-
-    $ docker run -it \
-        --blkio-weight 300 \
-        --blkio-weight-device "/dev/sda:200" \
-        ubuntu
-
-The `--device-read-bps` flag limits the read rate (bytes per second) from a device.
-For example, this command creates a container and limits the read rate to `1mb`
-per second from `/dev/sda`:
-
-    $ docker run -it --device-read-bps /dev/sda:1mb ubuntu
-
-The `--device-write-bps` flag limits the write rate (bytes per second)to a device.
-For example, this command creates a container and limits the write rate to `1mb`
-per second for `/dev/sda`:
-
-    $ docker run -it --device-write-bps /dev/sda:1mb ubuntu
-
-Both flags take limits in the `<device-path>:<limit>[unit]` format. Both read
-and write rates must be a positive integer. You can specify the rate in `kb`
-(kilobytes), `mb` (megabytes), or `gb` (gigabytes).
-
-The `--device-read-iops` flag limits read rate (IO per second) from a device.
-For example, this command creates a container and limits the read rate to
-`1000` IO per second from `/dev/sda`:
-
-    $ docker run -ti --device-read-iops /dev/sda:1000 ubuntu
-
-The `--device-write-iops` flag limits write rate (IO per second) to a device.
-For example, this command creates a container and limits the write rate to
-`1000` IO per second to `/dev/sda`:
-
-    $ docker run -ti --device-write-iops /dev/sda:1000 ubuntu
-
-Both flags take limits in the `<device-path>:<limit>` format. Both read and
-write rates must be a positive integer.
-
-## Additional groups
-    --group-add: Add additional groups to run as
-
-By default, the docker container process runs with the supplementary groups looked
-up for the specified user. If one wants to add more to that list of groups, then
-one can use this flag:
-
-    $ docker run --rm --group-add audio --group-add nogroup --group-add 777 busybox id
-    uid=0(root) gid=0(root) groups=10(wheel),29(audio),99(nogroup),777
-
-## Runtime privilege and Linux capabilities
-
-    --cap-add: Add Linux capabilities
-    --cap-drop: Drop Linux capabilities
-    --privileged=false: Give extended privileges to this container
-    --device=[]: Allows you to run devices inside the container without the --privileged flag.
-
-By default, Docker containers are "unprivileged" and cannot, for
-example, run a Docker daemon inside a Docker container. This is because
-by default a container is not allowed to access any devices, but a
-"privileged" container is given access to all devices (see
-the documentation on [cgroups devices](https://www.kernel.org/doc/Documentation/cgroup-v1/devices.txt)).
-
-When the operator executes `docker run --privileged`, Docker will enable
-access to all devices on the host as well as set some configuration
-in AppArmor or SELinux to allow the container nearly all the same access to the
-host as processes running outside containers on the host. Additional
-information about running with `--privileged` is available on the
-[Docker Blog](http://blog.docker.com/2013/09/docker-can-now-run-within-docker/).
-
-If you want to limit access to a specific device or devices you can use
-the `--device` flag. It allows you to specify one or more devices that
-will be accessible within the container.
-
-    $ docker run --device=/dev/snd:/dev/snd ...
-
-By default, the container will be able to `read`, `write`, and `mknod` these devices.
-This can be overridden using a third `:rwm` set of options to each `--device` flag:
-
-    $ docker run --device=/dev/sda:/dev/xvdc --rm -it ubuntu fdisk  /dev/xvdc
-
-    Command (m for help): q
-    $ docker run --device=/dev/sda:/dev/xvdc:r --rm -it ubuntu fdisk  /dev/xvdc
-    You will not be able to write the partition table.
-
-    Command (m for help): q
-
-    $ docker run --device=/dev/sda:/dev/xvdc:w --rm -it ubuntu fdisk  /dev/xvdc
-        crash....
-
-    $ docker run --device=/dev/sda:/dev/xvdc:m --rm -it ubuntu fdisk  /dev/xvdc
-    fdisk: unable to open /dev/xvdc: Operation not permitted
-
-In addition to `--privileged`, the operator can have fine grain control over the
-capabilities using `--cap-add` and `--cap-drop`. By default, Docker has a default
-list of capabilities that are kept. The following table lists the Linux capability
-options which are allowed by default and can be dropped.

-Both flags support the value `ALL`, so if the
-operator wants to have all capabilities but `MKNOD` they could use:
-
-    $ docker run --cap-add=ALL --cap-drop=MKNOD ...
-
-For interacting with the network stack, instead of using `--privileged` they
-should use `--cap-add=NET_ADMIN` to modify the network interfaces.

-## Logging drivers (--log-driver)
-
-The container can have a different logging driver than the Docker daemon. Use
-the `--log-driver=VALUE` with the `docker run` command to configure the
-container's logging driver. The following options are supported:
-
-| Driver      | Description                                                                                                                   |
-| ----------- | ----------------------------------------------------------------------------------------------------------------------------- |
-| `none`      | Disables any logging for the container. `docker logs` won't be available with this driver.                                    |
-| `json-file` | Default logging driver for Docker. Writes JSON messages to file.  No logging options are supported for this driver.           |
-| `syslog`    | Syslog logging driver for Docker. Writes log messages to syslog.                                                              |
-| `journald`  | Journald logging driver for Docker. Writes log messages to `journald`.                                                        |

-## Overriding Dockerfile image defaults
-
-When a developer builds an image from a [*Dockerfile*](builder.md)
-or when she commits it, the developer can set a number of default parameters
-that take effect when the image starts up as a container.
-
-Four of the Dockerfile commands cannot be overridden at runtime: `FROM`,
-`MAINTAINER`, `RUN`, and `ADD`. Everything else has a corresponding override
-in `docker run`. We'll go through what the developer might have set in each
-Dockerfile instruction and how the operator can override that setting.
-
- - [CMD (Default Command or Options)](#cmd-default-command-or-options)
- - [ENTRYPOINT (Default Command to Execute at Runtime)](
-    #entrypoint-default-command-to-execute-at-runtime)
- - [EXPOSE (Incoming Ports)](#expose-incoming-ports)
- - [ENV (Environment Variables)](#env-environment-variables)
- - [HEALTHCHECK](#healthcheck)
- - [VOLUME (Shared Filesystems)](#volume-shared-filesystems)
- - [USER](#user)
- - [WORKDIR](#workdir)
-
-### CMD (default command or options)
-
-Recall the optional `COMMAND` in the Docker
-commandline:
-
-    $ docker run [OPTIONS] IMAGE[:TAG|@DIGEST] [COMMAND] [ARG...]
-
-This command is optional because the person who created the `IMAGE` may
-have already provided a default `COMMAND` using the Dockerfile `CMD`
-instruction. As the operator (the person running a container from the
-image), you can override that `CMD` instruction just by specifying a new
-`COMMAND`.
-
-If the image also specifies an `ENTRYPOINT` then the `CMD` or `COMMAND`
-get appended as arguments to the `ENTRYPOINT`.
-
-### ENTRYPOINT (default command to execute at runtime)
-
-    --entrypoint="": Overwrite the default entrypoint set by the image
-
-The `ENTRYPOINT` of an image is similar to a `COMMAND` because it
-specifies what executable to run when the container starts, but it is
-(purposely) more difficult to override. The `ENTRYPOINT` gives a
-container its default nature or behavior, so that when you set an
-`ENTRYPOINT` you can run the container *as if it were that binary*,
-complete with default options, and you can pass in more options via the
-`COMMAND`. But, sometimes an operator may want to run something else
-inside the container, so you can override the default `ENTRYPOINT` at
-runtime by using a string to specify the new `ENTRYPOINT`. Here is an
-example of how to run a shell in a container that has been set up to
-automatically run something else (like `/usr/bin/redis-server`):
-
-    $ docker run -it --entrypoint /bin/bash example/redis
-
-or two examples of how to pass more parameters to that ENTRYPOINT:
-
-    $ docker run -it --entrypoint /bin/bash example/redis -c ls -l
-    $ docker run -it --entrypoint /usr/bin/redis-cli example/redis --help
-
-You can reset a containers entrypoint by passing an empty string, for example:
-
-    $ docker run -it --entrypoint="" mysql bash
-
-> **Note**: Passing `--entrypoint` will clear out any default command set on the
-> image (i.e. any `CMD` instruction in the Dockerfile used to build it).
-
-### EXPOSE (incoming ports)
-
-The following `run` command options work with container networking:
-
-    --expose=[]: Expose a port or a range of ports inside the container.
-                 These are additional to those exposed by the `EXPOSE` instruction
-    -P         : Publish all exposed ports to the host interfaces
-    -p=[]      : Publish a container᾿s port or a range of ports to the host
-                   format: ip:hostPort:containerPort | ip::containerPort | hostPort:containerPort | containerPort
-                   Both hostPort and containerPort can be specified as a
-                   range of ports. When specifying ranges for both, the
-                   number of container ports in the range must match the
-                   number of host ports in the range, for example:
-                       -p 1234-1236:1234-1236/tcp
-
-                   When specifying a range for hostPort only, the
-                   containerPort must not be a range.  In this case the
-                   container port is published somewhere within the
-                   specified hostPort range. (e.g., `-p 1234-1236:1234/tcp`)
-
-                   (use 'docker port' to see the actual mapping)
-
-    --link=""  : Add link to another container (<name or id>:alias or <name or id>)
-
-With the exception of the `EXPOSE` directive, an image developer hasn't
-got much control over networking. The `EXPOSE` instruction defines the
-initial incoming ports that provide services. These ports are available
-to processes inside the container. An operator can use the `--expose`
-option to add to the exposed ports.
-
-To expose a container's internal port, an operator can start the
-container with the `-P` or `-p` flag. The exposed port is accessible on
-the host and the ports are available to any client that can reach the
-host.
-
-The `-P` option publishes all the ports to the host interfaces. Docker
-binds each exposed port to a random port on the host. The range of
-ports are within an *ephemeral port range* defined by
-`/proc/sys/net/ipv4/ip_local_port_range`. Use the `-p` flag to
-explicitly map a single port or range of ports.
-
-The port number inside the container (where the service listens) does
-not need to match the port number exposed on the outside of the
-container (where clients connect). For example, inside the container an
-HTTP service is listening on port 80 (and so the image developer
-specifies `EXPOSE 80` in the Dockerfile). At runtime, the port might be
-bound to 42800 on the host. To find the mapping between the host ports
-and the exposed ports, use `docker port`.
-
-If the operator uses `--link` when starting a new client container in the
-default bridge network, then the client container can access the exposed
-port via a private networking interface.
-If `--link` is used when starting a container in a user-defined network as
-described in [*Docker network overview*](https://docs.docker.com/engine/userguide/networking/),
-it will provide a named alias for the container being linked to.
-
-### ENV (environment variables)
-
-Docker automatically sets some environment variables when creating a Linux
-container. Docker does not set any environment variables when creating a Windows
-container.
-
-The following environment variables are set for Linux containers:
-
-| Variable | Value |
-| -------- | ----- |
-| `HOME` | Set based on the value of `USER` |
-| `HOSTNAME` | The hostname associated with the container |
-| `PATH` | Includes popular directories, such as `/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin` |
-| `TERM` | `xterm` if the container is allocated a pseudo-TTY |
-
-
-Additionally, the operator can **set any environment variable** in the
-container by using one or more `-e` flags, even overriding those mentioned
-above, or already defined by the developer with a Dockerfile `ENV`. If the
-operator names an environment variable without specifying a value, then the
-current value of the named variable is propagated into the container's environment:
-
-```bash
-$ export today=Wednesday
-$ docker run -e "deep=purple" -e today --rm alpine env
-PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
-HOSTNAME=d2219b854598
-deep=purple
-today=Wednesday
-HOME=/root
-```
-
-```PowerShell
-PS C:\> docker run --rm -e "foo=bar" microsoft/nanoserver cmd /s /c set
-ALLUSERSPROFILE=C:\ProgramData
-APPDATA=C:\Users\ContainerAdministrator\AppData\Roaming
-CommonProgramFiles=C:\Program Files\Common Files
-CommonProgramFiles(x86)=C:\Program Files (x86)\Common Files

-TMP=C:\Users\ContainerAdministrator\AppData\Local\Temp
-USERDOMAIN=User Manager
-USERNAME=ContainerAdministrator
-USERPROFILE=C:\Users\ContainerAdministrator
-windir=C:\Windows
-```
-
-Similarly the operator can set the **HOSTNAME** (Linux) or **COMPUTERNAME** (Windows) with `-h`.
-
-### HEALTHCHECK
-
-```
-  --health-cmd            Command to run to check health
-  --health-interval       Time between running the check
-  --health-retries        Consecutive failures needed to report unhealthy
-  --health-timeout        Maximum time to allow one check to run
-  --health-start-period   Start period for the container to initialize before starting health-retries countdown
-  --no-healthcheck        Disable any container-specified HEALTHCHECK
-```
-
-Example:
-
-    {% raw %}
-    $ docker run --name=test -d \
-        --health-cmd='stat /etc/passwd || exit 1' \
-        --health-interval=2s \

-      ]
-    }
-    {% endraw %}
-
-The health status is also displayed in the `docker ps` output.
-
-### TMPFS (mount tmpfs filesystems)
-
-```bash
---tmpfs=[]: Create a tmpfs mount with: container-dir[:<options>],
-            where the options are identical to the Linux
-            'mount -t tmpfs -o' command.
-```
-
-The example below mounts an empty tmpfs into the container with the `rw`,
-`noexec`, `nosuid`, and `size=65536k` options.
-
-    $ docker run -d --tmpfs /run:rw,noexec,nosuid,size=65536k my_image
-
-### VOLUME (shared filesystems)
-
-    -v, --volume=[host-src:]container-dest[:<options>]: Bind mount a volume.
-    The comma-delimited `options` are [rw|ro], [z|Z],
-    [[r]shared|[r]slave|[r]private], and [nocopy].
-    The 'host-src' is an absolute path or a name value.
-
-    If neither 'rw' or 'ro' is specified then the volume is mounted in
-    read-write mode.
-
-    The `nocopy` modes is used to disable automatic copying requested volume
-    path in the container to the volume storage location.
-    For named volumes, `copy` is the default mode. Copy modes are not supported
-    for bind-mounted volumes.
-
-    --volumes-from="": Mount all volumes from the given container(s)
-
-> **Note**:
-> When using systemd to manage the Docker daemon's start and stop, in the systemd
-> unit file there is an option to control mount propagation for the Docker daemon
-> itself, called `MountFlags`. The value of this setting may cause Docker to not
-> see mount propagation changes made on the mount point. For example, if this value
-> is `slave`, you may not be able to use the `shared` or `rshared` propagation on
-> a volume.
-
-The volumes commands are complex enough to have their own documentation
-in section [*Manage data in
-containers*](https://docs.docker.com/engine/tutorials/dockervolumes/). A developer can define
-one or more `VOLUME`'s associated with an image, but only the operator
-can give access from one container to another (or from a container to a
-volume mounted on the host).
-
-The `container-dest` must always be an absolute path such as `/src/docs`.
-The `host-src` can either be an absolute path or a `name` value. If you
-supply an absolute path for the `host-dir`, Docker bind-mounts to the path
-you specify. If you supply a `name`, Docker creates a named volume by that `name`.
-
-A `name` value must start with an alphanumeric character,
-followed by `a-z0-9`, `_` (underscore), `.` (period) or `-` (hyphen).
-An absolute path starts with a `/` (forward slash).
-
-For example, you can specify either `/foo` or `foo` for a `host-src` value.
-If you supply the `/foo` value, Docker creates a bind-mount. If you supply
-the `foo` specification, Docker creates a named volume.
-
-### USER
-
-`root` (id = 0) is the default user within a container. The image developer can
-create additional users. Those users are accessible by name.  When passing a numeric
-ID, the user does not have to exist in the container.
-
-The developer can set a default user to run the first process with the
-Dockerfile `USER` instruction. When starting a container, the operator can override
-the `USER` instruction by passing the `-u` option.
-
-    -u="", --user="": Sets the username or UID used and optionally the groupname or GID for the specified command.
-
-    The followings examples are all valid:
-    --user=[ user | user:group | uid | uid:gid | user:gid | uid:group ]
-
-> **Note:** if you pass a numeric uid, it must be in the range of 0-2147483647.
-
-### WORKDIR
-
-The default working directory for running binaries within a container is the
-root directory (`/`), but the developer can set a different default with the
-Dockerfile `WORKDIR` command. The operator can override this with:
-
-    -w="": Working directory inside the container

-# Docker Checkpoint & Restore
-
-Checkpoint & Restore is a new feature that allows you to freeze a running
-container by checkpointing it, which turns its state into a collection of files
-on disk. Later, the container can be restored from the point it was frozen.
-
-This is accomplished using a tool called [CRIU](http://criu.org), which is an
-external dependency of this feature. A good overview of the history of
-checkpoint and restore in Docker is available in this
-[Kubernetes blog post](http://blog.kubernetes.io/2015/07/how-did-quake-demo-from-dockercon-work.html).
-
-## Installing CRIU
-
-If you use a Debian system, you can add the CRIU PPA and install with apt-get
-[from the criu launchpad](https://launchpad.net/~criu/+archive/ubuntu/ppa).
-
-Alternatively, you can [build CRIU from source](http://criu.org/Installation).
-
-You need at least version 2.0 of CRIU to run checkpoint/restore in Docker.
-
-## Use cases for checkpoint & restore
-
-This feature is currently focused on single-host use cases for checkpoint and
-restore. Here are a few:
-
-- Restarting the host machine without stopping/starting containers
-- Speeding up the start time of slow start applications
-- "Rewinding" processes to an earlier point in time
-- "Forensic debugging" of running processes
-
-Another primary use case of checkpoint & restore outside of Docker is the live
-migration of a server from one machine to another. This is possible with the
-current implementation, but not currently a priority (and so the workflow is
-not optimized for the task).
-
-## Using checkpoint & restore
-
-A new top level command `docker checkpoint` is introduced, with three subcommands:
-- `create` (creates a new checkpoint)
-- `ls` (lists existing checkpoints)
-- `rm` (deletes an existing checkpoint)
-
-Additionally, a `--checkpoint` flag is added to the container start command.
-
-The options for checkpoint create:
-
-    Usage:  docker checkpoint create [OPTIONS] CONTAINER CHECKPOINT
-
-    Create a checkpoint from a running container
-
-      --leave-running=false    Leave the container running after checkpoint
-      --checkpoint-dir         Use a custom checkpoint storage directory
-
-And to restore a container:
-
-    Usage:  docker start --checkpoint CHECKPOINT_ID [OTHER OPTIONS] CONTAINER
-
-
-A simple example of using checkpoint & restore on a container:
-
-    $ docker run --security-opt=seccomp:unconfined --name cr -d busybox /bin/sh -c 'i=0; while true; do echo $i; i=$(expr $i + 1); sleep 1; done'
-    > abc0123
-
-    $ docker checkpoint create cr checkpoint1
-
-    # <later>
-    $ docker start --checkpoint checkpoint1 cr
-    > abc0123
-
-This process just logs an incrementing counter to stdout. If you `docker logs`
-in between running/checkpoint/restoring you should see that the counter
-increases while the process is running, stops while it's checkpointed, and
-resumes from the point it left off once you restore.
-
-## Current limitation
-
-seccomp is only supported by CRIU in very up to date kernels.
-
-External terminal (i.e. `docker run -t ..`) is not supported at the moment.
-If you try to create a checkpoint for a container with an external terminal, 
-it would fail:
-
-    $ docker checkpoint create cr checkpoint1
-    Error response from daemon: Cannot checkpoint container c1: rpc error: code = 2 desc = exit status 1: "criu failed: type NOTIFY errno 0\nlog file: /var/lib/docker/containers/eb62ebdbf237ce1a8736d2ae3c7d88601fc0a50235b0ba767b559a1f3c5a600b/checkpoints/checkpoint1/criu.work/dump.log\n"

-# Docker Stacks and Distributed Application Bundles
-
-## Overview
-
-Docker Stacks and Distributed Application Bundles are experimental features
-introduced in Docker 1.12 and Docker Compose 1.8, alongside the concept of
-swarm mode, and Nodes and Services in the Engine API.
-
-A Dockerfile can be built into an image, and containers can be created from
-that image. Similarly, a docker-compose.yml can be built into a **distributed
-application bundle**, and **stacks** can be created from that bundle. In that
-sense, the bundle is a multi-services distributable image format.
-
-As of Docker 1.12 and Compose 1.8, the features are experimental. Neither
-Docker Engine nor the Docker Registry supports distribution of bundles.
-
-## Producing a bundle
-
-The easiest way to produce a bundle is to generate it using `docker-compose`
-from an existing `docker-compose.yml`. Of course, that's just *one* possible way
-to proceed, in the same way that `docker build` isn't the only way to produce a
-Docker image.
-
-From `docker-compose`:
-
-```bash
-$ docker-compose bundle
-WARNING: Unsupported key 'network_mode' in services.nsqd - ignoring
-WARNING: Unsupported key 'links' in services.nsqd - ignoring
-WARNING: Unsupported key 'volumes' in services.nsqd - ignoring
-[...]
-Wrote bundle to vossibility-stack.dab
-```
-
-## Creating a stack from a bundle
-
-A stack is created using the `docker deploy` command:
-
-```bash
-$ docker deploy --help
-Usage:  docker deploy [OPTIONS] STACK
-
-Deploy a new stack or update an existing stack
-
-Aliases:
-  deploy, up
-
-Options:
-      --bundle-file string    Path to a Distributed Application Bundle file
-  -c, --compose-file string   Path to a Compose file
-      --help                  Print usage
-      --with-registry-auth    Send registry authentication details to Swarm agents
-
-```
-
-Let's deploy the stack created before:
-
-```bash
-$ docker deploy --bundle-file vossibility-stack.dab vossibility-stack
-Loading bundle from vossibility-stack.dab
-Creating service vossibility-stack_elasticsearch
-Creating service vossibility-stack_kibana
-Creating service vossibility-stack_logstash
-Creating service vossibility-stack_lookupd
-Creating service vossibility-stack_nsqd
-Creating service vossibility-stack_vossibility-collector
-```
-
-We can verify that services were correctly created:
-
-```bash
-$ docker service ls
-ID            NAME                                     MODE         REPLICAS    IMAGE

-```
-
-## Managing stacks
-
-Stacks are managed using the `docker stack` command:
-
-```bash
-# docker stack --help
-
-Usage:  docker stack COMMAND
-
-Manage Docker stacks
-
-Options:
-      --help   Print usage
-
-Commands:
-  deploy      Deploy a new stack or update an existing stack
-  ls          List stacks
-  ps          List the tasks in the stack
-  rm          Remove the stack
-  services    List the services in the stack
-
-Run 'docker stack COMMAND --help' for more information on a command.
-```
-
-## Bundle file format
-
-Distributed application bundles are described in a JSON format. When bundles
-are persisted as files, the file extension is `.dab` (Docker 1.12RC2 tools use
-`.dsb` for the file extension—this will be updated in the next release client).
-
-A bundle has two top-level fields: `version` and `services`. The version used
-by Docker 1.12 and later tools is `0.1`.
-
-`services` in the bundle are the services that comprise the app. They
-correspond to the new `Service` object introduced in the 1.12 Docker Engine API.
-
-A service has the following fields:
-
-<dl>
-    <dt>
-        Image (required) <code>string</code>
-    </dt>
-    <dd>
-        The image that the service will run. Docker images should be referenced
-        with full content hash to fully specify the deployment artifact for the
-        service. Example:
-        <code>postgres@sha256:f76245b04ddbcebab5bb6c28e76947f49222c99fec4aadb0bb
-        1c24821a 9e83ef</code>
-    </dd>
-    <dt>
-        Command <code>[]string</code>
-    </dt>
-    <dd>
-        Command to run in service containers.
-    </dd>
-    <dt>
-        Args <code>[]string</code>
-    </dt>
-    <dd>
-        Arguments passed to the service containers.
-    </dd>
-    <dt>
-        Env <code>[]string</code>
-    </dt>
-    <dd>
-        Environment variables.
-    </dd>
-    <dt>
-        Labels <code>map[string]string</code>
-    </dt>
-    <dd>
-        Labels used for setting meta data on services.
-    </dd>
-    <dt>
-        Ports <code>[]Port</code>
-    </dt>
-    <dd>
-        Service ports (composed of <code>Port</code> (<code>int</code>) and
-        <code>Protocol</code> (<code>string</code>). A service description can
-        only specify the container port to be exposed. These ports can be
-        mapped on runtime hosts at the operator's discretion.
-    </dd>
-
-    <dt>
-        WorkingDir <code>string</code>
-    </dt>
-    <dd>
-        Working directory inside the service containers.
-    </dd>
-
-    <dt>
-        User <code>string</code>
-    </dt>
-    <dd>
-        Username or UID (format: <code>&lt;name|uid&gt;[:&lt;group|gid&gt;]</code>).
-    </dd>
-
-    <dt>
-        Networks <code>[]string</code>
-    </dt>
-    <dd>
-        Networks that the service containers should be connected to. An entity
-        deploying a bundle should create networks as needed.
-    </dd>
-</dl>
-
-The following is an example of bundlefile with two services:
-
-```json
-{
-	"Version": "0.1",
-	"Services": {
-		"redis": {
-			"Image": "redis@sha256:4b24131101fa0117bcaa18ac37055fffd9176aa1a240392bb8ea85e0be50f2ce",
-			"Networks": ["default"]
-		},
-		"web": {
-			"Image": "dockercloud/hello-world@sha256:fe79a2cfbd17eefc344fb8419420808df95a1e22d93b7f621a7399fd1e9dca1d",
-			"Networks": ["default"],
-			"User": "web"
-		}
-	}
-}

-# Ipvlan Network Driver
-
-### Getting Started
-
-The Ipvlan driver is currently in experimental mode in order to incubate Docker users use cases and vet the implementation to ensure a hardened, production ready driver in a future release. Libnetwork now gives users total control over both IPv4 and IPv6 addressing. The VLAN driver builds on top of that in giving operators complete control of layer 2 VLAN tagging and even Ipvlan L3 routing for users interested in underlay network integration. For overlay deployments that abstract away physical constraints see the [multi-host overlay ](https://docs.docker.com/engine/userguide/networking/get-started-overlay/) driver.
-
-Ipvlan is a new twist on the tried and true network virtualization technique. The Linux implementations are extremely lightweight because rather than using the traditional Linux bridge for isolation, they are simply associated to a Linux Ethernet interface or sub-interface to enforce separation between networks and connectivity to the physical network.
-
-Ipvlan offers a number of unique features and plenty of room for further innovations with the various modes. Two high level advantages of these approaches are, the positive performance implications of bypassing the Linux bridge and the simplicity of having fewer moving parts. Removing the bridge that traditionally resides in between the Docker host NIC and container interface leaves a simple setup consisting of container interfaces, attached directly to the Docker host interface. This result is easy access for external facing services as there is no need for port mappings in these scenarios.
-
-### Pre-Requisites
-
-- The examples on this page are all single host and setup using Docker experimental builds that can be installed with the following instructions: [Install Docker experimental](https://github.com/docker/docker/tree/master/experimental)
-
-- All of the examples can be performed on a single host running Docker. Any examples using a sub-interface like `eth0.10` can be replaced with `eth0` or any other valid parent interface on the Docker host. Sub-interfaces with a `.` are created on the fly. `-o parent` interfaces can also be left out of the `docker network create` all together and the driver will create a `dummy` interface that will enable local host connectivity to perform the examples.
-
-- Kernel requirements:
- 
- - To check your current kernel version, use `uname -r` to display your kernel version
- - Ipvlan Linux kernel v4.2+ (support for earlier kernels exists but is buggy)
-
-### Ipvlan L2 Mode Example Usage
-
-An example of the ipvlan `L2` mode topology is shown in the following image. The driver is specified with `-d driver_name` option. In this case `-d ipvlan`.
-
-![Simple Ipvlan L2 Mode Example](images/ipvlan_l2_simple.png)
-
-The parent interface in the next example `-o parent=eth0` is configured as followed:
-
-```
-$ ip addr show eth0
-3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
-    inet 192.168.1.250/24 brd 192.168.1.255 scope global eth0
-```
-
-Use the network from the host's interface as the `--subnet` in the `docker network create`. The container will be attached to the same network as the host interface as set via the `-o parent=` option.
-
-Create the ipvlan network and run a container attaching to it:
-
-```
-# Ipvlan  (-o ipvlan_mode= Defaults to L2 mode if not specified)
-$ docker network  create -d ipvlan \
-    --subnet=192.168.1.0/24 \ 
-    --gateway=192.168.1.1 \
-    -o ipvlan_mode=l2 \
-    -o parent=eth0 db_net
-
-# Start a container on the db_net network
-$ docker  run --net=db_net -it --rm alpine /bin/sh
-
-# NOTE: the containers can NOT ping the underlying host interfaces as
-# they are intentionally filtered by Linux for additional isolation.
-```
-
-The default mode for Ipvlan is `l2`. If `-o ipvlan_mode=` are left unspecified, the default mode will be used. Similarly, if the `--gateway` is left empty, the first usable address on the network will be set as the gateway. For example, if the subnet provided in the network create is `--subnet=192.168.1.0/24` then the gateway the container receives is `192.168.1.1`.
-
-To help understand how this mode interacts with other hosts, the following figure shows the same layer 2 segment between two Docker hosts that applies to and Ipvlan L2 mode.
-
-![Multiple Ipvlan Hosts](images/macvlan-bridge-ipvlan-l2.png)
-
-The following will create the exact same network as the network `db_net` created prior, with the driver defaults for `--gateway=192.168.1.1` and `-o ipvlan_mode=l2`.
-
-```
-# Ipvlan  (-o ipvlan_mode= Defaults to L2 mode if not specified)
-$ docker network  create -d ipvlan \
-    --subnet=192.168.1.0/24 \ 
-    -o parent=eth0 db_net_ipv
-
-# Start a container with an explicit name in daemon mode
-$ docker  run --net=db_net_ipv --name=ipv1 -itd alpine /bin/sh
-
-# Start a second container and ping using the container name
-# to see the docker included name resolution functionality
-$ docker  run --net=db_net_ipv --name=ipv2 -it --rm alpine /bin/sh
-$ ping -c 4 ipv1
-
-# NOTE: the containers can NOT ping the underlying host interfaces as
-# they are intentionally filtered by Linux for additional isolation.
-```
-
-The drivers also support the `--internal` flag that will completely isolate containers on a network from any communications external to that network. Since network isolation is tightly coupled to the network's parent interface the result of leaving the `-o parent=` option off of a `docker network create` is the exact same as the `--internal` option. If the parent interface is not specified or the `--internal` flag is used, a netlink type `dummy` parent interface is created for the user and used as the parent interface effectively isolating the network completely.
-
-The following two `docker network create` examples result in identical networks that you can attach container to:
-
-```
-# Empty '-o parent=' creates an isolated network
-$ docker network  create -d ipvlan \
-    --subnet=192.168.10.0/24 isolated1
-
-# Explicit '--internal' flag is the same:
-$ docker network  create -d ipvlan \
-    --subnet=192.168.11.0/24 --internal isolated2
-
-# Even the '--subnet=' can be left empty and the default 
-# IPAM subnet of 172.18.0.0/16 will be assigned
-$ docker network  create -d ipvlan isolated3
-
-$ docker run --net=isolated1 --name=cid1 -it --rm alpine /bin/sh
-$ docker run --net=isolated2 --name=cid2 -it --rm alpine /bin/sh
-$ docker run --net=isolated3 --name=cid3 -it --rm alpine /bin/sh
-
-# To attach to any use `docker exec` and start a shell
-$ docker exec -it cid1 /bin/sh
-$ docker exec -it cid2 /bin/sh
-$ docker exec -it cid3 /bin/sh
-```
-
-### Ipvlan 802.1q Trunk L2 Mode Example Usage
-
-Architecturally, Ipvlan L2 mode trunking is the same as Macvlan with regard to gateways and L2 path isolation. There are nuances that can be advantageous for CAM table pressure in ToR switches, one MAC per port and MAC exhaustion on a host's parent NIC to name a few. The 802.1q trunk scenario looks the same. Both modes adhere to tagging standards and have seamless integration with the physical network for underlay integration and hardware vendor plugin integrations.
-
-Hosts on the same VLAN are typically on the same subnet and almost always are grouped together based on their security policy. In most scenarios, a multi-tier application is tiered into different subnets because the security profile of each process requires some form of isolation. For example, hosting your credit card processing on the same virtual network as the frontend webserver would be a regulatory compliance issue, along with circumventing the long standing best practice of layered defense in depth architectures. VLANs or the equivocal VNI (Virtual Network Identifier) when using the Overlay driver, are the first step in isolating tenant traffic.
-
-![Docker VLANs in Depth](images/vlans-deeper-look.png)
-
-The Linux sub-interface tagged with a vlan can either already exist or will be created when you call a `docker network create`. `docker network rm` will delete the sub-interface. Parent interfaces such as `eth0` are not deleted, only sub-interfaces with a netlink parent index > 0.
-
-For the driver to add/delete the vlan sub-interfaces the format needs to be `interface_name.vlan_tag`. Other sub-interface naming can be used as the specified parent, but the link will not be deleted automatically when `docker network rm` is invoked. 
-
-The option to use either existing parent vlan sub-interfaces or let Docker manage them enables the user to either completely manage the Linux interfaces and networking or let Docker create and delete the Vlan parent sub-interfaces (netlink `ip link`) with no effort from the user.
-
-For example: use `eth0.10` to denote a sub-interface of `eth0` tagged with the vlan id of `10`. The equivalent `ip link` command would be `ip link add link eth0 name eth0.10 type vlan id 10`.
-
-The example creates the vlan tagged networks and then start two containers to test connectivity between containers. Different Vlans cannot ping one another without a router routing between the two networks. The default namespace is not reachable per ipvlan design in order to isolate container namespaces from the underlying host.
-
-**Vlan ID 20**
-
-In the first network tagged and isolated by the Docker host, `eth0.20` is the parent interface tagged with vlan id `20` specified with `-o parent=eth0.20`. Other naming formats can be used, but the links need to be added and deleted manually using `ip link` or Linux configuration files. As long as the `-o parent` exists anything can be used if compliant with Linux netlink.
-
-```
-# now add networks and hosts as you would normally by attaching to the master (sub)interface that is tagged
-$ docker network  create  -d ipvlan \
-    --subnet=192.168.20.0/24 \
-    --gateway=192.168.20.1 \
-    -o parent=eth0.20 ipvlan20
-
-# in two separate terminals, start a Docker container and the containers can now ping one another.
-$ docker run --net=ipvlan20 -it --name ivlan_test1 --rm alpine /bin/sh
-$ docker run --net=ipvlan20 -it --name ivlan_test2 --rm alpine /bin/sh
-```
-
-**Vlan ID 30**
-
-In the second network, tagged and isolated by the Docker host, `eth0.30` is the parent interface tagged with vlan id `30` specified with `-o parent=eth0.30`. The `ipvlan_mode=` defaults to l2 mode `ipvlan_mode=l2`. It can also be explicitly set with the same result as shown in the next example.
-
-```
-# now add networks and hosts as you would normally by attaching to the master (sub)interface that is tagged.
-$ docker network  create  -d ipvlan \
-    --subnet=192.168.30.0/24 \
-    --gateway=192.168.30.1 \
-    -o parent=eth0.30 \
-    -o ipvlan_mode=l2 ipvlan30
-
-# in two separate terminals, start a Docker container and the containers can now ping one another.
-$ docker run --net=ipvlan30 -it --name ivlan_test3 --rm alpine /bin/sh
-$ docker run --net=ipvlan30 -it --name ivlan_test4 --rm alpine /bin/sh
-```
-
-The gateway is set inside of the container as the default gateway. That gateway would typically be an external router on the network.
-
-```
-$$ ip route
-  default via 192.168.30.1 dev eth0
-  192.168.30.0/24 dev eth0  src 192.168.30.2
-```
-
-Example: Multi-Subnet Ipvlan L2 Mode starting two containers on the same subnet and pinging one another. In order for the `192.168.114.0/24` to reach `192.168.116.0/24` it requires an external router in L2 mode. L3 mode can route between subnets that share a common `-o parent=`. 
-
-Secondary addresses on network routers are common as an address space becomes exhausted to add another secondary to an L3 vlan interface or commonly referred to as a "switched virtual interface" (SVI).
-
-```
-$ docker network  create  -d ipvlan \
-    --subnet=192.168.114.0/24 --subnet=192.168.116.0/24 \
-    --gateway=192.168.114.254  --gateway=192.168.116.254 \
-     -o parent=eth0.114 \
-     -o ipvlan_mode=l2 ipvlan114
-     
-$ docker run --net=ipvlan114 --ip=192.168.114.10 -it --rm alpine /bin/sh
-$ docker run --net=ipvlan114 --ip=192.168.114.11 -it --rm alpine /bin/sh
-```
-
-A key takeaway is, operators have the ability to map their physical network into their virtual network for integrating containers into their environment with no operational overhauls required. NetOps simply drops an 802.1q trunk into the Docker host. That virtual link would be the `-o parent=` passed in the network creation. For untagged (non-VLAN) links, it is as simple as `-o parent=eth0` or for 802.1q trunks with VLAN IDs each network gets mapped to the corresponding VLAN/Subnet from the network.
-
-An example being, NetOps provides VLAN ID and the associated subnets for VLANs being passed on the Ethernet link to the Docker host server. Those values are simply plugged into the `docker network create` commands when provisioning the Docker networks. These are persistent configurations that are applied every time the Docker engine starts which alleviates having to manage often complex configuration files. The network interfaces can also be managed manually by being pre-created and docker networking will never modify them, simply use them as parent interfaces. Example mappings from NetOps to Docker network commands are as follows:
-
-- VLAN: 10, Subnet: 172.16.80.0/24, Gateway: 172.16.80.1
-
-    - `--subnet=172.16.80.0/24 --gateway=172.16.80.1 -o parent=eth0.10` 
-
-- VLAN: 20, IP subnet: 172.16.50.0/22, Gateway: 172.16.50.1
-
-    - `--subnet=172.16.50.0/22 --gateway=172.16.50.1 -o parent=eth0.20 ` 
-
-- VLAN: 30, Subnet: 10.1.100.0/16, Gateway: 10.1.100.1
-
-    - `--subnet=10.1.100.0/16 --gateway=10.1.100.1 -o parent=eth0.30` 
-
-### IPVlan L3 Mode Example
-
-IPVlan will require routes to be distributed to each endpoint. The driver only builds the Ipvlan L3 mode port and attaches the container to the interface. Route distribution throughout a cluster is beyond the initial implementation of this single host scoped driver. In L3 mode, the Docker host is very similar to a router starting new networks in the container. They are on networks that the upstream network will not know about without route distribution. For those curious how Ipvlan L3 will fit into container networking see the following examples.
-
-![Docker Ipvlan L2 Mode](images/ipvlan-l3.png)
-
-Ipvlan L3 mode drops all broadcast and multicast traffic. This reason alone makes Ipvlan L3 mode a prime candidate for those looking for massive scale and predictable network integrations. It is predictable and in turn will lead to greater uptimes because there is no bridging involved. Bridging loops have been responsible for high profile outages that can be hard to pinpoint depending on the size of the failure domain. This is due to the cascading nature of BPDUs (Bridge Port Data Units) that are flooded throughout a broadcast domain (VLAN) to find and block topology loops. Eliminating bridging domains, or at the least, keeping them isolated to a pair of ToRs (top of rack switches) will reduce hard to troubleshoot bridging instabilities. Ipvlan L2 modes is well suited for isolated VLANs only trunked into a pair of ToRs that can provide a loop-free non-blocking fabric. The next step further is to route at the edge via Ipvlan L3 mode that reduces a failure domain to a local host only. 
-
-- L3 mode needs to be on a separate subnet as the default namespace since it requires a netlink route in the default namespace pointing to the Ipvlan parent interface.
-
-- The parent interface used in this example is `eth0` and it is on the subnet `192.168.1.0/24`. Notice the `docker network` is **not** on the same subnet as `eth0`.
-
-- Unlike ipvlan l2 modes, different subnets/networks can ping one another as long as they share the same parent interface `-o parent=`.
-
-```
-$$ ip a show eth0
-3: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
-    link/ether 00:50:56:39:45:2e brd ff:ff:ff:ff:ff:ff
-    inet 192.168.1.250/24 brd 192.168.1.255 scope global eth0
-```
-
-- A traditional gateway doesn't mean much to an L3 mode Ipvlan interface since there is no broadcast traffic allowed. Because of that, the container default gateway simply points to the containers `eth0` device. See below for CLI output of `ip route` or `ip -6 route` from inside an L3 container for details.
-
-The mode ` -o ipvlan_mode=l3` must be explicitly specified since the default ipvlan mode is `l2`.
-
-The following example does not specify a parent interface. The network drivers will create a dummy type link for the user rather then rejecting the network creation and isolating containers from only communicating with one another.
-
-```
-# Create the Ipvlan L3 network
-$ docker network  create  -d ipvlan \
-    --subnet=192.168.214.0/24 \
-    --subnet=10.1.214.0/24 \
-     -o ipvlan_mode=l3 ipnet210
-
-# Test 192.168.214.0/24 connectivity
-$ docker run --net=ipnet210 --ip=192.168.214.10 -itd alpine /bin/sh
-$ docker run --net=ipnet210 --ip=10.1.214.10 -itd alpine /bin/sh
-
-# Test L3 connectivity from 10.1.214.0/24 to 192.168.212.0/24
-$ docker run --net=ipnet210 --ip=192.168.214.9 -it --rm alpine ping -c 2 10.1.214.10
-
-# Test L3 connectivity from 192.168.212.0/24 to 10.1.214.0/24
-$ docker run --net=ipnet210 --ip=10.1.214.9 -it --rm alpine ping -c 2 192.168.214.10
-
-```
-
-Notice there is no `--gateway=` option in the network create. The field is ignored if one is specified `l3` mode. Take a look at the container routing table from inside of the container:
-
-```
-# Inside an L3 mode container
-$$ ip route
-  default dev eth0
-  192.168.214.0/24 dev eth0  src 192.168.214.10
-```
-
-In order to ping the containers from a remote Docker host or the container be able to ping a remote host, the remote host or the physical network in between need to have a route pointing to the host IP address of the container's Docker host eth interface. More on this as we evolve the Ipvlan `L3` story.
-
-### Dual Stack IPv4 IPv6 Ipvlan L2 Mode
-
-- Not only does Libnetwork give you complete control over IPv4 addressing, but it also gives you total control over IPv6 addressing as well as feature parity between the two address families.
-
-- The next example will start with IPv6 only. Start two containers on the same VLAN `139` and ping one another. Since the IPv4 subnet is not specified, the default IPAM will provision a default IPv4 subnet. That subnet is isolated unless the upstream network is explicitly routing it on VLAN `139`.
-
-```
-# Create a v6 network
-$ docker network create -d ipvlan \
-    --subnet=2001:db8:abc2::/64 --gateway=2001:db8:abc2::22 \
-    -o parent=eth0.139 v6ipvlan139
-    
-# Start a container on the network
-$ docker run --net=v6ipvlan139 -it --rm alpine /bin/sh
-
-```
-
-View the container eth0 interface and v6 routing table:
-
-```
-# Inside the IPv6 container
-$$ ip a show eth0
-75: eth0@if55: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default

-The next example with setup a dual stack IPv4/IPv6 network with an example VLAN ID of `140`.
-
-Next create a network with two IPv4 subnets and one IPv6 subnets, all of which have explicit gateways:
-
-```

-    --subnet=192.168.140.0/24 --subnet=192.168.142.0/24 \

-
-Start a container and view eth0 and both v4 & v6 routing tables:

-
-Start a second container with a specific `--ip4` address and ping the first host using IPv4 packets:
-
-```
-$ docker run --net=ipvlan140 --ip=192.168.140.10 -it --rm alpine /bin/sh
-```
-
-**Note**: Different subnets on the same parent interface in Ipvlan `L2` mode cannot ping one another. That requires a router to proxy-arp the requests with a secondary subnet. However, Ipvlan `L3` will route the unicast traffic between disparate subnets as long as they share the same `-o parent` parent link.
-
-### Dual Stack IPv4 IPv6 Ipvlan L3 Mode 
-
-**Example:** IpVlan L3 Mode Dual Stack IPv4/IPv6, Multi-Subnet w/ 802.1q Vlan Tag:118
-
-As in all of the examples, a tagged VLAN interface does not have to be used. The sub-interfaces can be swapped with `eth0`, `eth1`, `bond0` or any other valid interface on the host other then the `lo` loopback.
-
-The primary difference you will see is that L3 mode does not create a default route with a next-hop but rather sets a default route pointing to `dev eth` only since ARP/Broadcasts/Multicast are all filtered by Linux as per the design. Since the parent interface is essentially acting as a router, the parent interface IP and subnet needs to be different from the container networks. That is the opposite of bridge and L2 modes, which need to be on the same subnet (broadcast domain) in order to forward broadcast and multicast packets.
-
-```
-# Create an IPv6+IPv4 Dual Stack Ipvlan L3 network 
-# Gateways for both v4 and v6 are set to a dev e.g. 'default dev eth0'
-$ docker network  create  -d ipvlan \
-    --subnet=192.168.110.0/24 \
-    --subnet=192.168.112.0/24 \
-    --subnet=2001:db8:abc6::/64 \
-     -o parent=eth0 \
-     -o ipvlan_mode=l3 ipnet110
-
-
-# Start a few of containers on the network (ipnet110) 
-# in separate terminals and check connectivity
-$ docker run --net=ipnet110 -it --rm alpine /bin/sh
-# Start a second container specifying the v6 address
-$ docker run --net=ipnet110 --ip6=2001:db8:abc6::10 -it --rm alpine /bin/sh
-# Start a third specifying the IPv4 address
-$ docker run --net=ipnet110 --ip=192.168.112.30 -it --rm alpine /bin/sh
-# Start a 4th specifying both the IPv4 and IPv6 addresses
-$ docker run --net=ipnet110 --ip6=2001:db8:abc6::50 --ip=192.168.112.50 -it --rm alpine /bin/sh
-```
-
-Interface and routing table outputs are as follows:
-
-```
-$$ ip a show eth0
-63: eth0@if59: <BROADCAST,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default
-    link/ether 00:50:56:2b:29:40 brd ff:ff:ff:ff:ff:ff
-    inet 192.168.112.2/24 scope global eth0
-       valid_lft forever preferred_lft forever
-    inet6 2001:db8:abc4::250:56ff:fe2b:2940/64 scope link
-       valid_lft forever preferred_lft forever
-    inet6 2001:db8:abc6::10/64 scope link nodad
-       valid_lft forever preferred_lft forever
-     
-# Note the default route is simply the eth device because ARPs are filtered.
-$$ ip route
-  default dev eth0  scope link
-  192.168.112.0/24 dev eth0  proto kernel  scope link  src 192.168.112.2
-
-$$ ip -6 route
-2001:db8:abc4::/64 dev eth0  proto kernel  metric 256
-2001:db8:abc6::/64 dev eth0  proto kernel  metric 256
-default dev eth0  metric 1024
-```
-
-*Note:* There may be a bug when specifying `--ip6=` addresses when you delete a container with a specified v6 address and then start a new container with the same v6 address it throws the following like the address isn't properly being released to the v6 pool. It will fail to unmount the container and be left dead.
-
-```
-docker: Error response from daemon: Address already in use.
-```
-
-### Manually Creating 802.1q Links
-
-**Vlan ID 40**
-
-If a user does not want the driver to create the vlan sub-interface it simply needs to exist prior to the `docker network create`. If you have sub-interface naming that is not `interface.vlan_id` it is honored in the `-o parent=` option again as long as the interface exists and is up.
-
-Links, when manually created, can be named anything as long as they exist when the network is created. Manually created links do not get deleted regardless of the name when the network is deleted with `docker network rm`.
-
-```
-# create a new sub-interface tied to dot1q vlan 40
-$ ip link add link eth0 name eth0.40 type vlan id 40
-
-# enable the new sub-interface
-$ ip link set eth0.40 up
-
-# now add networks and hosts as you would normally by attaching to the master (sub)interface that is tagged
-$ docker network  create  -d ipvlan \
-   --subnet=192.168.40.0/24 \
-   --gateway=192.168.40.1 \
-   -o parent=eth0.40 ipvlan40
-
-# in two separate terminals, start a Docker container and the containers can now ping one another.
-$ docker run --net=ipvlan40 -it --name ivlan_test5 --rm alpine /bin/sh
-$ docker run --net=ipvlan40 -it --name ivlan_test6 --rm alpine /bin/sh
-```
-
-**Example:** Vlan sub-interface manually created with any name:
-
-```
-# create a new sub interface tied to dot1q vlan 40
-$ ip link add link eth0 name foo type vlan id 40
-
-# enable the new sub-interface
-$ ip link set foo up
-
-# now add networks and hosts as you would normally by attaching to the master (sub)interface that is tagged
-$ docker network  create  -d ipvlan \
-    --subnet=192.168.40.0/24 --gateway=192.168.40.1 \
-    -o parent=foo ipvlan40
-
-# in two separate terminals, start a Docker container and the containers can now ping one another.
-$ docker run --net=ipvlan40 -it --name ivlan_test5 --rm alpine /bin/sh
-$ docker run --net=ipvlan40 -it --name ivlan_test6 --rm alpine /bin/sh
-```
-
-Manually created links can be cleaned up with:
-
-```
-$ ip link del foo
-```
-
-As with all of the Libnetwork drivers, they can be mixed and matched, even as far as running 3rd party ecosystem drivers in parallel for maximum flexibility to the Docker user.

-# NAME
-
-Dockerfile - automate the steps of creating a Docker image
-
-# INTRODUCTION
-
-The **Dockerfile** is a configuration file that automates the steps of creating
-a Docker image. It is similar to a Makefile. Docker reads instructions from the
-**Dockerfile** to automate the steps otherwise performed manually to create an
-image. To build an image, create a file called **Dockerfile**.
-
-The **Dockerfile** describes the steps taken to assemble the image. When the
-**Dockerfile** has been created, call the `docker build` command, using the
-path of directory that contains **Dockerfile** as the argument.
-
-# SYNOPSIS
-
-INSTRUCTION arguments
-
-For example:
-
-  FROM image
-
-# DESCRIPTION
-
-A Dockerfile is a file that automates the steps of creating a Docker image.
-A Dockerfile is similar to a Makefile.
-
-# USAGE
-
-  docker build .
-
-  -- Runs the steps and commits them, building a final image.
-  The path to the source repository defines where to find the context of the
-  build. The build is run by the Docker daemon, not the CLI. The whole
-  context must be transferred to the daemon. The Docker CLI reports
-  `"Sending build context to Docker daemon"` when the context is sent to the
-  daemon.
-
-  ```
-  docker build -t repository/tag .
-  ```
-
-  -- specifies a repository and tag at which to save the new image if the build
-  succeeds. The Docker daemon runs the steps one-by-one, committing the result
-  to a new image if necessary, before finally outputting the ID of the new
-  image. The Docker daemon automatically cleans up the context it is given.
-
-  Docker re-uses intermediate images whenever possible. This significantly
-  accelerates the *docker build* process.
-
-# FORMAT
-
-  `FROM image`
-
-  `FROM image:tag`
-
-  `FROM image@digest`
-
-  -- The **FROM** instruction sets the base image for subsequent instructions. A
-  valid Dockerfile must have **FROM** as its first instruction. The image can be any
-  valid image. It is easy to start by pulling an image from the public
-  repositories.
-
-  -- **FROM** must be the first non-comment instruction in Dockerfile.
-
-  -- **FROM** may appear multiple times within a single Dockerfile in order to create
-  multiple images. Make a note of the last image ID output by the commit before
-  each new **FROM** command.
-
-  -- If no tag is given to the **FROM** instruction, Docker applies the
-  `latest` tag. If the used tag does not exist, an error is returned.
-
-  -- If no digest is given to the **FROM** instruction, Docker applies the
-  `latest` tag. If the used tag does not exist, an error is returned.
-
-**MAINTAINER**
-  -- **MAINTAINER** sets the Author field for the generated images.
-  Useful for providing users with an email or url for support.
-
-**RUN**
-  -- **RUN** has two forms:
-
-  ```
-  # the command is run in a shell - /bin/sh -c
-  RUN <command>
-
-  # Executable form
-  RUN ["executable", "param1", "param2"]
-  ```
-
-
-  -- The **RUN** instruction executes any commands in a new layer on top of the current
-  image and commits the results. The committed image is used for the next step in
-  Dockerfile.
-
-  -- Layering **RUN** instructions and generating commits conforms to the core
-  concepts of Docker where commits are cheap and containers can be created from
-  any point in the history of an image. This is similar to source control.  The
-  exec form makes it possible to avoid shell string munging. The exec form makes
-  it possible to **RUN** commands using a base image that does not contain `/bin/sh`.
-
-  Note that the exec form is parsed as a JSON array, which means that you must
-  use double-quotes (") around words not single-quotes (').
-
-**CMD**
-  -- **CMD** has three forms:
-
-  ```
-  # Executable form
-  CMD ["executable", "param1", "param2"]`
-
-  # Provide default arguments to ENTRYPOINT
-  CMD ["param1", "param2"]`
-
-  # the command is run in a shell - /bin/sh -c
-  CMD command param1 param2
-  ```
-
-  -- There should be only one **CMD** in a Dockerfile. If more than one **CMD** is listed, only
-  the last **CMD** takes effect.
-  The main purpose of a **CMD** is to provide defaults for an executing container.
-  These defaults may include an executable, or they can omit the executable. If
-  they omit the executable, an **ENTRYPOINT** must be specified.
-  When used in the shell or exec formats, the **CMD** instruction sets the command to
-  be executed when running the image.
-  If you use the shell form of the **CMD**, the `<command>` executes in `/bin/sh -c`:
-
-  Note that the exec form is parsed as a JSON array, which means that you must
-  use double-quotes (") around words not single-quotes (').
-
-  ```
-  FROM ubuntu
-  CMD echo "This is a test." | wc -
-  ```
-
-  -- If you run **command** without a shell, then you must express the command as a
-  JSON array and give the full path to the executable. This array form is the
-  preferred form of **CMD**. All additional parameters must be individually expressed
-  as strings in the array:
-
-  ```
-  FROM ubuntu
-  CMD ["/usr/bin/wc","--help"]
-  ```
-
-  -- To make the container run the same executable every time, use **ENTRYPOINT** in
-  combination with **CMD**.
-  If the user specifies arguments to `docker run`, the specified commands
-  override the default in **CMD**.
-  Do not confuse **RUN** with **CMD**. **RUN** runs a command and commits the result.
-  **CMD** executes nothing at build time, but specifies the intended command for
-  the image.
-
-**LABEL**
-  -- `LABEL <key>=<value> [<key>=<value> ...]`or
-  ```
-  LABEL <key>[ <value>]
-  LABEL <key>[ <value>]
-  ...
-  ```
-  The **LABEL** instruction adds metadata to an image. A **LABEL** is a
-  key-value pair. To specify a **LABEL** without a value, simply use an empty
-  string. To include spaces within a **LABEL** value, use quotes and
-  backslashes as you would in command-line parsing.
-
-  ```
-  LABEL com.example.vendor="ACME Incorporated"
-  LABEL com.example.vendor "ACME Incorporated"
-  LABEL com.example.vendor.is-beta ""
-  LABEL com.example.vendor.is-beta=
-  LABEL com.example.vendor.is-beta=""
-  ```
-
-  An image can have more than one label. To specify multiple labels, separate
-  each key-value pair by a space.
-
-  Labels are additive including `LABEL`s in `FROM` images. As the system
-  encounters and then applies a new label, new `key`s override any previous
-  labels with identical keys.
-
-  To display an image's labels, use the `docker inspect` command.
-
-**EXPOSE**
-  -- `EXPOSE <port> [<port>...]`
-  The **EXPOSE** instruction informs Docker that the container listens on the
-  specified network ports at runtime. Docker uses this information to
-  interconnect containers using links and to set up port redirection on the host
-  system.
-
-**ENV**
-  -- `ENV <key> <value>`
-  The **ENV** instruction sets the environment variable <key> to
-  the value `<value>`. This value is passed to all future
-  **RUN**, **ENTRYPOINT**, and **CMD** instructions. This is
-  functionally equivalent to prefixing the command with `<key>=<value>`.  The
-  environment variables that are set with **ENV** persist when a container is run
-  from the resulting image. Use `docker inspect` to inspect these values, and
-  change them using `docker run --env <key>=<value>`.
-
-  Note that setting "`ENV DEBIAN_FRONTEND noninteractive`" may cause
-  unintended consequences, because it will persist when the container is run
-  interactively, as with the following command: `docker run -t -i image bash`
-
-**ADD**
-  -- **ADD** has two forms:
-
-  ```
-  ADD <src> <dest>
-
-  # Required for paths with whitespace
-  ADD ["<src>",... "<dest>"]
-  ```
-
-  The **ADD** instruction copies new files, directories
-  or remote file URLs to the filesystem of the container at path `<dest>`.
-  Multiple `<src>` resources may be specified but if they are files or directories
-  then they must be relative to the source directory that is being built
-  (the context of the build). The `<dest>` is the absolute path, or path relative
-  to **WORKDIR**, into which the source is copied inside the target container.
-  If the `<src>` argument is a local file in a recognized compression format
-  (tar, gzip, bzip2, etc) then it is unpacked at the specified `<dest>` in the
-  container's filesystem.  Note that only local compressed files will be unpacked,
-  i.e., the URL download and archive unpacking features cannot be used together.
-  All new directories are created with mode 0755 and with the uid and gid of **0**.
-
-**COPY**
-  -- **COPY** has two forms:
-
-  ```
-  COPY <src> <dest>
-
-  # Required for paths with whitespace
-  COPY ["<src>",... "<dest>"]
-  ```
-
-  The **COPY** instruction copies new files from `<src>` and
-  adds them to the filesystem of the container at path <dest>. The `<src>` must be
-  the path to a file or directory relative to the source directory that is
-  being built (the context of the build) or a remote file URL. The `<dest>` is an
-  absolute path, or a path relative to **WORKDIR**, into which the source will
-  be copied inside the target container. If you **COPY** an archive file it will
-  land in the container exactly as it appears in the build context without any
-  attempt to unpack it.  All new files and directories are created with mode **0755**
-  and with the uid and gid of **0**.
-
-**ENTRYPOINT**
-  -- **ENTRYPOINT** has two forms:
-
-  ```
-  # executable form
-  ENTRYPOINT ["executable", "param1", "param2"]`
-
-  # run command in a shell - /bin/sh -c
-  ENTRYPOINT command param1 param2
-  ```
-
-  -- An **ENTRYPOINT** helps you configure a
-  container that can be run as an executable. When you specify an **ENTRYPOINT**,
-  the whole container runs as if it was only that executable.  The **ENTRYPOINT**
-  instruction adds an entry command that is not overwritten when arguments are
-  passed to docker run. This is different from the behavior of **CMD**. This allows
-  arguments to be passed to the entrypoint, for instance `docker run <image> -d`
-  passes the -d argument to the **ENTRYPOINT**.  Specify parameters either in the
-  **ENTRYPOINT** JSON array (as in the preferred exec form above), or by using a **CMD**
-  statement.  Parameters in the **ENTRYPOINT** are not overwritten by the docker run
-  arguments.  Parameters specified via **CMD** are overwritten by docker run
-  arguments.  Specify a plain string for the **ENTRYPOINT**, and it will execute in
-  `/bin/sh -c`, like a **CMD** instruction:
-
-  ```
-  FROM ubuntu
-  ENTRYPOINT wc -l -
-  ```
-
-  This means that the Dockerfile's image always takes stdin as input (that's
-  what "-" means), and prints the number of lines (that's what "-l" means). To
-  make this optional but default, use a **CMD**:
-
-  ```
-  FROM ubuntu
-  CMD ["-l", "-"]
-  ENTRYPOINT ["/usr/bin/wc"]
-  ```
-
-**VOLUME**
-  -- `VOLUME ["/data"]`
-  The **VOLUME** instruction creates a mount point with the specified name and marks
-  it as holding externally-mounted volumes from the native host or from other
-  containers.
-
-**USER**
-  -- `USER daemon`
-  Sets the username or UID used for running subsequent commands.
-
-  The **USER** instruction can optionally be used to set the group or GID. The
-  followings examples are all valid:
-  USER [user | user:group | uid | uid:gid | user:gid | uid:group ]
-
-  Until the **USER** instruction is set, instructions will be run as root. The USER
-  instruction can be used any number of times in a Dockerfile, and will only affect
-  subsequent commands.
-
-**WORKDIR**
-  -- `WORKDIR /path/to/workdir`
-  The **WORKDIR** instruction sets the working directory for the **RUN**, **CMD**,
-  **ENTRYPOINT**, **COPY** and **ADD** Dockerfile commands that follow it. It can
-  be used multiple times in a single Dockerfile. Relative paths are defined
-  relative to the path of the previous **WORKDIR** instruction. For example:
-
-  ```
-  WORKDIR /a
-  WORKDIR b
-  WORKDIR c
-  RUN pwd
-  ```
-
-  In the above example, the output of the **pwd** command is **a/b/c**.
-
-**ARG**
-   -- ARG <name>[=<default value>]
-
-  The `ARG` instruction defines a variable that users can pass at build-time to
-  the builder with the `docker build` command using the `--build-arg
-  <varname>=<value>` flag. If a user specifies a build argument that was not
-  defined in the Dockerfile, the build outputs a warning.
-
-  ```
-  [Warning] One or more build-args [foo] were not consumed
-  ```
-
-  The Dockerfile author can define a single variable by specifying `ARG` once or many
-  variables by specifying `ARG` more than once. For example, a valid Dockerfile:
-
-  ```
-  FROM busybox
-  ARG user1
-  ARG buildno
-  ...
-  ```
-
-  A Dockerfile author may optionally specify a default value for an `ARG` instruction:
-
-  ```
-  FROM busybox
-  ARG user1=someuser
-  ARG buildno=1
-  ...
-  ```
-
-  If an `ARG` value has a default and if there is no value passed at build-time, the
-  builder uses the default.
-
-  An `ARG` variable definition comes into effect from the line on which it is
-  defined in the `Dockerfile` not from the argument's use on the command-line or
-  elsewhere.  For example, consider this Dockerfile:
-
-  ```
-  1 FROM busybox
-  2 USER ${user:-some_user}
-  3 ARG user
-  4 USER $user
-  ...
-  ```
-  A user builds this file by calling:
-
-  ```
-  $ docker build --build-arg user=what_user Dockerfile
-  ```
-
-  The `USER` at line 2 evaluates to `some_user` as the `user` variable is defined on the
-  subsequent line 3. The `USER` at line 4 evaluates to `what_user` as `user` is
-  defined and the `what_user` value was passed on the command line. Prior to its definition by an
-  `ARG` instruction, any use of a variable results in an empty string.
-
-  > **Warning:** It is not recommended to use build-time variables for
-  >  passing secrets like github keys, user credentials etc. Build-time variable
-  >  values are visible to any user of the image with the `docker history` command.
-
-  You can use an `ARG` or an `ENV` instruction to specify variables that are
-  available to the `RUN` instruction. Environment variables defined using the
-  `ENV` instruction always override an `ARG` instruction of the same name. Consider
-  this Dockerfile with an `ENV` and `ARG` instruction.
-
-  ```
-  1 FROM ubuntu
-  2 ARG CONT_IMG_VER
-  3 ENV CONT_IMG_VER v1.0.0
-  4 RUN echo $CONT_IMG_VER
-  ```
-  Then, assume this image is built with this command:
-
-  ```
-  $ docker build --build-arg CONT_IMG_VER=v2.0.1 Dockerfile
-  ```
-
-  In this case, the `RUN` instruction uses `v1.0.0` instead of the `ARG` setting
-  passed by the user:`v2.0.1` This behavior is similar to a shell
-  script where a locally scoped variable overrides the variables passed as
-  arguments or inherited from environment, from its point of definition.
-
-  Using the example above but a different `ENV` specification you can create more
-  useful interactions between `ARG` and `ENV` instructions:
-
-  ```
-  1 FROM ubuntu
-  2 ARG CONT_IMG_VER
-  3 ENV CONT_IMG_VER ${CONT_IMG_VER:-v1.0.0}
-  4 RUN echo $CONT_IMG_VER
-  ```
-
-  Unlike an `ARG` instruction, `ENV` values are always persisted in the built
-  image. Consider a docker build without the --build-arg flag:
-
-  ```
-  $ docker build Dockerfile
-  ```
-
-  Using this Dockerfile example, `CONT_IMG_VER` is still persisted in the image but
-  its value would be `v1.0.0` as it is the default set in line 3 by the `ENV` instruction.
-
-  The variable expansion technique in this example allows you to pass arguments
-  from the command line and persist them in the final image by leveraging the
-  `ENV` instruction. Variable expansion is only supported for [a limited set of
-  Dockerfile instructions.](#environment-replacement)
-
-  Docker has a set of predefined `ARG` variables that you can use without a
-  corresponding `ARG` instruction in the Dockerfile.
-
-  * `HTTP_PROXY`
-  * `http_proxy`
-  * `HTTPS_PROXY`
-  * `https_proxy`
-  * `FTP_PROXY`
-  * `ftp_proxy`
-  * `NO_PROXY`
-  * `no_proxy`
-
-  To use these, simply pass them on the command line using the `--build-arg
-  <varname>=<value>` flag.
-
-**ONBUILD**
-  -- `ONBUILD [INSTRUCTION]`
-  The **ONBUILD** instruction adds a trigger instruction to an image. The
-  trigger is executed at a later time, when the image is used as the base for
-  another build. Docker executes the trigger in the context of the downstream
-  build, as if the trigger existed immediately after the **FROM** instruction in
-  the downstream Dockerfile.
-
-  You can register any build instruction as a trigger. A trigger is useful if
-  you are defining an image to use as a base for building other images. For
-  example, if you are defining an application build environment or a daemon that
-  is customized with a user-specific configuration.  
-
-  Consider an image intended as a reusable python application builder. It must
-  add application source code to a particular directory, and might need a build
-  script called after that. You can't just call **ADD** and **RUN** now, because
-  you don't yet have access to the application source code, and it is different
-  for each application build.
-
-  -- Providing application developers with a boilerplate Dockerfile to copy-paste
-  into their application is inefficient, error-prone, and
-  difficult to update because it mixes with application-specific code.
-  The solution is to use **ONBUILD** to register instructions in advance, to
-  run later, during the next build stage.

-# DESCRIPTION
-This will read the Dockerfile from the directory specified in **PATH**.
-It also sends any other files and directories found in the current
-directory to the Docker daemon. The contents of this directory would
-be used by **ADD** commands found within the Dockerfile.
-
-Warning, this will send a lot of data to the Docker daemon depending
-on the contents of the current directory. The build is run by the Docker
-daemon, not by the CLI, so the whole context must be transferred to the daemon. 
-The Docker CLI reports "Sending build context to Docker daemon" when the context is sent to
-the daemon.
-
-When the URL to a tarball archive or to a single Dockerfile is given, no context is sent from
-the client to the Docker daemon. In this case, the Dockerfile at the root of the archive and
-the rest of the archive will get used as the context of the build.  When a Git repository is
-set as the **URL**, the repository is cloned locally and then sent as the context.
-
-# OPTIONS
-**-f**, **--file**=*PATH/Dockerfile*
-   Path to the Dockerfile to use. If the path is a relative path and you are
-   building from a local directory, then the path must be relative to that
-   directory. If you are building from a remote URL pointing to either a
-   tarball or a Git repository, then the path must be relative to the root of
-   the remote context. In all cases, the file must be within the build context.
-   The default is *Dockerfile*.
-
-**--squash**=*true*|*false*
-   **Experimental Only**
-   Once the image is built, squash the new layers into a new image with a single
-   new layer. Squashing does not destroy any existing image, rather it creates a new
-   image with the content of the squashed layers. This effectively makes it look
-   like all `Dockerfile` commands were created with a single layer. The build
-   cache is preserved with this method.
-
-   **Note**: using this option means the new image will not be able to take
-   advantage of layer sharing with other images and may use significantly more
-   space.
-
-   **Note**: using this option you may see significantly more space used due to
-   storing two copies of the image, one for the build cache with all the cache
-   layers in tact, and one for the squashed version.
-
-**--add-host**=[]
-   Add a custom host-to-IP mapping (host:ip)
-
-   Add a line to /etc/hosts. The format is hostname:ip.  The **--add-host**
-option can be set multiple times.
-
-**--build-arg**=*variable*
-   name and value of a **buildarg**.
-
-   For example, if you want to pass a value for `http_proxy`, use
-   `--build-arg=http_proxy="http://some.proxy.url"`
-
-   Users pass these values at build-time. Docker uses the `buildargs` as the
-   environment context for command(s) run via the Dockerfile's `RUN` instruction
-   or for variable expansion in other Dockerfile instructions. This is not meant
-   for passing secret values. [Read more about the buildargs instruction](https://docs.docker.com/engine/reference/builder/#arg)
-
-**--cache-from**=""
-   Set image that will be used as a build cache source.
-
-**--force-rm**=*true*|*false*
-   Always remove intermediate containers, even after unsuccessful builds. The default is *false*.
-
-**--isolation**="*default*"
-   Isolation specifies the type of isolation technology used by containers. 
-
-**--label**=*label*
-   Set metadata for an image
-
-**--no-cache**=*true*|*false*
-   Do not use cache when building the image. The default is *false*.
-
-**--iidfile**=""
-   Write the image ID to the file
-
-**--help**
-  Print usage statement
-
-**--pull**=*true*|*false*
-   Always attempt to pull a newer version of the image. The default is *false*.
-
-**--compress**=*true*|*false*
-    Compress the build context using gzip. The default is *false*.
-
-**-q**, **--quiet**=*true*|*false*
-   Suppress the build output and print image ID on success. The default is *false*.
-
-**--rm**=*true*|*false*
-   Remove intermediate containers after a successful build. The default is *true*.
-
-**-t**, **--tag**=""
-   Repository names (and optionally with tags) to be applied to the resulting 
-   image in case of success. Refer to **docker-tag(1)** for more information
-   about valid tag names.
-
-**-m**, **--memory**=*MEMORY*
-  Memory limit
-
-**--memory-swap**=*LIMIT*
-   A limit value equal to memory plus swap. Must be used with the  **-m**
-(**--memory**) flag. The swap `LIMIT` should always be larger than **-m**
-(**--memory**) value.
-
-   The format of `LIMIT` is `<number>[<unit>]`. Unit can be `b` (bytes),
-`k` (kilobytes), `m` (megabytes), or `g` (gigabytes). If you don't specify a
-unit, `b` is used. Set LIMIT to `-1` to enable unlimited swap.
-
-**--network**=*bridge*
-  Set the networking mode for the RUN instructions during build. Supported standard
-  values are: `bridge`, `host`, `none` and `container:<name|id>`. Any other value
-  is taken as a custom network's name or ID which this container should connect to.
-
-**--shm-size**=*SHM-SIZE*
-  Size of `/dev/shm`. The format is `<number><unit>`. `number` must be greater than `0`.
-  Unit is optional and can be `b` (bytes), `k` (kilobytes), `m` (megabytes), or `g` (gigabytes). If you omit the unit, the system uses bytes.
-  If you omit the size entirely, the system uses `64m`.
-
-**--cpu-shares**=*0*
-  CPU shares (relative weight).
-
-  By default, all containers get the same proportion of CPU cycles.
-  CPU shares is a 'relative weight', relative to the default setting of 1024.
-  This default value is defined here: 
-  ```
-   cat /sys/fs/cgroup/cpu/cpu.shares
-   1024
-  ```
-  You can change this proportion by adjusting the container's CPU share 
-  weighting relative to the weighting of all other running containers.
-
-  To modify the proportion from the default of 1024, use the **--cpu-shares**
-  flag to set the weighting to 2 or higher.
-
-      Container   CPU share    Flag             
-      {C0}        60% of CPU  --cpu-shares=614 (614 is 60% of 1024)
-      {C1}        40% of CPU  --cpu-shares=410 (410 is 40% of 1024)
-
-  The proportion is only applied when CPU-intensive processes are running.
-  When tasks in one container are idle, the other containers can use the
-  left-over CPU time. The actual amount of CPU time used varies depending on
-  the number of containers running on the system.
-
-  For example, consider three containers, where one has **--cpu-shares=1024** and
-  two others have **--cpu-shares=512**. When processes in all three
-  containers attempt to use 100% of CPU, the first container would receive
-  50% of the total CPU time. If you add a fourth container with **--cpu-shares=1024**,
-  the first container only gets 33% of the CPU. The remaining containers
-  receive 16.5%, 16.5% and 33% of the CPU.
-
-
-      Container   CPU share   Flag                CPU time            
-      {C0}        100%        --cpu-shares=1024   33%
-      {C1}        50%         --cpu-shares=512    16.5%
-      {C2}        50%         --cpu-shares=512    16.5%
-      {C4}        100%        --cpu-shares=1024   33%
-
-
-  On a multi-core system, the shares of CPU time are distributed across the CPU
-  cores. Even if a container is limited to less than 100% of CPU time, it can
-  use 100% of each individual CPU core.
-
-  For example, consider a system with more than three cores. If you start one
-  container **{C0}** with **--cpu-shares=512** running one process, and another container
-  **{C1}** with **--cpu-shares=1024** running two processes, this can result in the following
-  division of CPU shares:
-
-      PID    container    CPU    CPU share
-      100    {C0}         0      100% of CPU0
-      101    {C1}         1      100% of CPU1
-      102    {C1}         2      100% of CPU2
-
-**--cpu-period**=*0*
-  Limit the CPU CFS (Completely Fair Scheduler) period.
-
-  Limit the container's CPU usage. This flag causes the kernel to restrict the
-  container's CPU usage to the period you specify.
-
-**--cpu-quota**=*0*
-  Limit the CPU CFS (Completely Fair Scheduler) quota. 
-
-  By default, containers run with the full CPU resource. This flag causes the
-kernel to restrict the container's CPU usage to the quota you specify.
-
-**--cpuset-cpus**=*CPUSET-CPUS*
-  CPUs in which to allow execution (0-3, 0,1).
-
-**--cpuset-mems**=*CPUSET-MEMS*
-  Memory nodes (MEMs) in which to allow execution (0-3, 0,1). Only effective on
-  NUMA systems.
-
-  For example, if you have four memory nodes on your system (0-3), use `--cpuset-mems=0,1`
-to ensure the processes in your Docker container only use memory from the first
-two memory nodes.
-
-**--cgroup-parent**=*CGROUP-PARENT*
-  Path to `cgroups` under which the container's `cgroup` are created.
-
-  If the path is not absolute, the path is considered relative to the `cgroups` path of the init process.
-Cgroups are created if they do not already exist.
-
-**--target**=""
-   Set the target build stage name.
-
-**--ulimit**=[]
-  Ulimit options
-
-  For more information about `ulimit` see [Setting ulimits in a

-
-# EXAMPLES
-
-## Building an image using a Dockerfile located inside the current directory
-
-Docker images can be built using the build command and a Dockerfile:
-
-    docker build .
-
-During the build process Docker creates intermediate images. In order to
-keep them, you must explicitly set `--rm=false`.
-
-    docker build --rm=false .
-
-A good practice is to make a sub-directory with a related name and create
-the Dockerfile in that directory. For example, a directory called mongo may
-contain a Dockerfile to create a Docker MongoDB image. Likewise, another
-directory called httpd may be used to store Dockerfiles for Apache web
-server images.
-
-It is also a good practice to add the files required for the image to the
-sub-directory. These files will then be specified with the `COPY` or `ADD`
-instructions in the `Dockerfile`.
-
-Note: If you include a tar file (a good practice), then Docker will
-automatically extract the contents of the tar file specified within the `ADD`
-instruction into the specified target.
-
-## Building an image and naming that image
-
-A good practice is to give a name to the image you are building. Note that 
-only a-z0-9-_. should be used for consistency.  There are no hard rules here but it is best to give the names consideration. 
-
-The **-t**/**--tag** flag is used to rename an image. Here are some examples:
-
-Though it is not a good practice, image names can be arbitrary:
-
-    docker build -t myimage .
-
-A better approach is to provide a fully qualified and meaningful repository,
-name, and tag (where the tag in this context means the qualifier after 
-the ":"). In this example we build a JBoss image for the Fedora repository 
-and give it the version 1.0:
-
-    docker build -t fedora/jboss:1.0 .
-
-The next example is for the "whenry" user repository and uses Fedora and
-JBoss and gives it the version 2.1 :
-
-    docker build -t whenry/fedora-jboss:v2.1 .
-
-If you do not provide a version tag then Docker will assign `latest`:
-
-    docker build -t whenry/fedora-jboss .
-
-When you list the images, the image above will have the tag `latest`.
-
-You can apply multiple tags to an image. For example, you can apply the `latest`
-tag to a newly built image and add another tag that references a specific
-version.
-For example, to tag an image both as `whenry/fedora-jboss:latest` and
-`whenry/fedora-jboss:v2.1`, use the following:
-
-    docker build -t whenry/fedora-jboss:latest -t whenry/fedora-jboss:v2.1 .
-
-So renaming an image is arbitrary but consideration should be given to 
-a useful convention that makes sense for consumers and should also take
-into account Docker community conventions.
-
-
-## Building an image using a URL
-
-This will clone the specified GitHub repository from the URL and use it
-as context. The Dockerfile at the root of the repository is used as
-Dockerfile. This only works if the GitHub repository is a dedicated
-repository.
-
-    docker build github.com/scollier/purpletest
-
-Note: You can set an arbitrary Git repository via the `git://` scheme.
-
-## Building an image using a URL to a tarball'ed context
-
-This will send the URL itself to the Docker daemon. The daemon will fetch the
-tarball archive, decompress it and use its contents as the build context.  The 
-Dockerfile at the root of the archive and the rest of the archive will get used
-as the context of the build. If you pass an **-f PATH/Dockerfile** option as well,
-the system will look for that file inside the contents of the tarball.
-
-    docker build -f dev/Dockerfile https://10.10.10.1/docker/context.tar.gz
-
-Note: supported compression formats are 'xz', 'bzip2', 'gzip' and 'identity' (no compression).
-
-## Specify isolation technology for container (--isolation)
-
-This option is useful in situations where you are running Docker containers on
-Windows. The `--isolation=<value>` option sets a container's isolation
-technology. On Linux, the only supported is the `default` option which uses
-Linux namespaces. On Microsoft Windows, you can specify these values:
-
-* `default`: Use the value specified by the Docker daemon's `--exec-opt` . If the `daemon` does not specify an isolation technology, Microsoft Windows uses `process` as its default value.
-* `process`: Namespace isolation only.
-* `hyperv`: Hyper-V hypervisor partition-based isolation.
-
-Specifying the `--isolation` flag without a value is the same as setting `--isolation="default"`.

-# NAME
-HOME/.docker/config.json - Default Docker configuration file
-
-# INTRODUCTION
-
-By default, the Docker command line stores its configuration files in a
-directory called `.docker` within your `$HOME` directory.  Docker manages most of
-the files in the configuration directory and you should not modify them.
-However, you *can modify* the `config.json` file to control certain aspects of
-how the `docker` command behaves.
-
-Currently, you can modify the `docker` command behavior using environment
-variables or command-line options. You can also use options within
-`config.json` to modify some of the same behavior. When using these
-mechanisms, you must keep in mind the order of precedence among them. Command
-line options override environment variables and environment variables override
-properties you specify in a `config.json` file.
-
-The `config.json` file stores a JSON encoding of several properties:
-
-* The `HttpHeaders` property specifies a set of headers to include in all messages
-sent from the Docker client to the daemon. Docker does not try to interpret or
-understand these header; it simply puts them into the messages. Docker does not
-allow these headers to change any headers it sets for itself.
-
-* The `psFormat` property specifies the default format for `docker ps` output.
-When the `--format` flag is not provided with the `docker ps` command,
-Docker's client uses this property. If this property is not set, the client
-falls back to the default table format. For a list of supported formatting
-directives, see **docker-ps(1)**.
-
-* The `detachKeys` property specifies the default key sequence which
-detaches the container. When the `--detach-keys` flag is not provide
-with the `docker attach`, `docker exec`, `docker run` or `docker
-start`, Docker's client uses this property. If this property is not
-set, the client falls back to the default sequence `ctrl-p,ctrl-q`.
-
-
-* The `imagesFormat` property  specifies the default format for `docker images`
-output. When the `--format` flag is not provided with the `docker images`
-command, Docker's client uses this property. If this property is not set, the
-client falls back to the default table format. For a list of supported
-formatting directives, see **docker-images(1)**.
-
-You can specify a different location for the configuration files via the
-`DOCKER_CONFIG` environment variable or the `--config` command line option. If
-both are specified, then the `--config` option overrides the `DOCKER_CONFIG`
-environment variable:
-
-    docker --config ~/testconfigs/ ps
-
-This command instructs Docker to use the configuration files in the
-`~/testconfigs/` directory when running the `ps` command.
-
-## Examples
-
-Following is a sample `config.json` file:
-
-    {
-      "HttpHeaders": {
-        "MyHeader": "MyValue"
-      },
-      "psFormat": "table {{.ID}}\\t{{.Image}}\\t{{.Command}}\\t{{.Labels}}",
-      "imagesFormat": "table {{.ID}}\\t{{.Repository}}\\t{{.Tag}}\\t{{.CreatedAt}}",
-      "detachKeys": "ctrl-e,e"
-    }

-IMAGE [COMMAND] [ARG...]
-
-# DESCRIPTION
-
-Run a process in a new container. **docker run** starts a process with its own
-file system, its own networking, and its own isolated process tree. The IMAGE
-which starts the process may define defaults related to the process that will be
-run in the container, the networking to expose, and more, but **docker run**
-gives final control to the operator or administrator who starts the container
-from the image. For that reason **docker run** has more options than any other
-Docker command.
-
-If the IMAGE is not already loaded then **docker run** will pull the IMAGE, and
-all image dependencies, from the repository in the same way running **docker
-pull** IMAGE, before it starts the container from that image.
-
-# OPTIONS
-**-a**, **--attach**=[]
-   Attach to STDIN, STDOUT or STDERR.
-
-   In foreground mode (the default when **-d**
-is not specified), **docker run** can start the process in the container
-and attach the console to the process's standard input, output, and standard
-error. It can even pretend to be a TTY (this is what most commandline
-executables expect) and pass along signals. The **-a** option can be set for
-each of stdin, stdout, and stderr.
-
-**--add-host**=[]
-   Add a custom host-to-IP mapping (host:ip)
-
-   Add a line to /etc/hosts. The format is hostname:ip.  The **--add-host**
-option can be set multiple times.
-
-**--blkio-weight**=*0*
-   Block IO weight (relative weight) accepts a weight value between 10 and 1000.
-
-**--blkio-weight-device**=[]
-   Block IO weight (relative device weight, format: `DEVICE_NAME:WEIGHT`).
-
-**--cpu-shares**=*0*
-   CPU shares (relative weight)
-
-   By default, all containers get the same proportion of CPU cycles. This proportion
-can be modified by changing the container's CPU share weighting relative
-to the weighting of all other running containers.
-
-To modify the proportion from the default of 1024, use the **--cpu-shares**
-flag to set the weighting to 2 or higher.
-
-The proportion will only apply when CPU-intensive processes are running.
-When tasks in one container are idle, other containers can use the
-left-over CPU time. The actual amount of CPU time will vary depending on
-the number of containers running on the system.
-
-For example, consider three containers, one has a cpu-share of 1024 and
-two others have a cpu-share setting of 512. When processes in all three
-containers attempt to use 100% of CPU, the first container would receive
-50% of the total CPU time. If you add a fourth container with a cpu-share
-of 1024, the first container only gets 33% of the CPU. The remaining containers
-receive 16.5%, 16.5% and 33% of the CPU.
-
-On a multi-core system, the shares of CPU time are distributed over all CPU
-cores. Even if a container is limited to less than 100% of CPU time, it can
-use 100% of each individual CPU core.
-
-For example, consider a system with more than three cores. If you start one
-container **{C0}** with **-c=512** running one process, and another container
-**{C1}** with **-c=1024** running two processes, this can result in the following
-division of CPU shares:
-
-    PID    container	CPU	CPU share
-    100    {C0}		0	100% of CPU0
-    101    {C1}		1	100% of CPU1
-    102    {C1}		2	100% of CPU2
-
-**--cap-add**=[]
-   Add Linux capabilities
-
-**--cap-drop**=[]
-   Drop Linux capabilities
-
-**--cgroup-parent**=""
-   Path to cgroups under which the cgroup for the container will be created. If the path is not absolute, the path is considered to be relative to the cgroups path of the init process. Cgroups will be created if they do not already exist.
-
-**--cidfile**=""
-   Write the container ID to the file
-
-**--cpu-count**=*0*
-    Limit the number of CPUs available for execution by the container.
-    
-    On Windows Server containers, this is approximated as a percentage of total CPU usage.
-
-    On Windows Server containers, the processor resource controls are mutually exclusive, the order of precedence is CPUCount first, then CPUShares, and CPUPercent last.
-
-**--cpu-percent**=*0*
-    Limit the percentage of CPU available for execution by a container running on a Windows daemon.
-
-    On Windows Server containers, the processor resource controls are mutually exclusive, the order of precedence is CPUCount first, then CPUShares, and CPUPercent last.
-
-**--cpu-period**=*0*
-   Limit the CPU CFS (Completely Fair Scheduler) period
-
-   Limit the container's CPU usage. This flag tell the kernel to restrict the container's CPU usage to the period you specify.
-
-**--cpuset-cpus**=""
-   CPUs in which to allow execution (0-3, 0,1)
-
-**--cpuset-mems**=""
-   Memory nodes (MEMs) in which to allow execution (0-3, 0,1). Only effective on NUMA systems.
-
-   If you have four memory nodes on your system (0-3), use `--cpuset-mems=0,1`
-then processes in your Docker container will only use memory from the first
-two memory nodes.
-
-**--cpu-quota**=*0*
-   Limit the CPU CFS (Completely Fair Scheduler) quota
-
-   Limit the container's CPU usage. By default, containers run with the full
-CPU resource. This flag tell the kernel to restrict the container's CPU usage
-to the quota you specify.
-
-**--cpu-rt-period**=0
-   Limit the CPU real-time period in microseconds
-
-   Limit the container's Real Time CPU usage. This flag tell the kernel to restrict the container's Real Time CPU usage to the period you specify.
-
-**--cpu-rt-runtime**=0
-   Limit the CPU real-time runtime in microseconds
-
-   Limit the containers Real Time CPU usage. This flag tells the kernel to limit the amount of time in a given CPU period Real Time tasks may consume. Ex:
-   Period of 1,000,000us and Runtime of 950,000us means that this container could consume 95% of available CPU and leave the remaining 5% to normal priority tasks.
-
-   The sum of all runtimes across containers cannot exceed the amount allotted to the parent cgroup.
-
-**--cpus**=0.0
-   Number of CPUs. The default is *0.0* which means no limit.
-
-**-d**, **--detach**=*true*|*false*
-   Detached mode: run the container in the background and print the new container ID. The default is *false*.
-
-   At any time you can run **docker ps** in
-the other shell to view a list of the running containers. You can reattach to a
-detached container with **docker attach**.
-
-   When attached in the tty mode, you can detach from the container (and leave it
-running) using a configurable key sequence. The default sequence is `CTRL-p CTRL-q`.
-You configure the key sequence using the **--detach-keys** option or a configuration file.
-See **config-json(5)** for documentation on using a configuration file.
-
-**--detach-keys**=""
-   Override the key sequence for detaching a container. Format is a single character `[a-Z]` or `ctrl-<value>` where `<value>` is one of: `a-z`, `@`, `^`, `[`, `,` or `_`.
-
-**--device**=[]
-   Add a host device to the container (e.g. --device=/dev/sdc:/dev/xvdc:rwm)
-
-**--device-cgroup-rule**=[]
-   Add a rule to the cgroup allowed devices list.
-   
-   The rule is expected to be in the format specified in the Linux kernel documentation (Documentation/cgroup-v1/devices.txt):
-     - type: `a` (all), `c` (char) or `b` (block)
-     - major and minor: either a number or `*` for all
-     - permission: a composition of `r` (read), `w` (write) and `m` (mknod)
-
-   Example: `c 1:3 mr`: allow for character device with major `1` and minor `3` to be created (`m`) and read (`r`)
-
-**--device-read-bps**=[]
-   Limit read rate from a device (e.g. --device-read-bps=/dev/sda:1mb)
-
-**--device-read-iops**=[]
-   Limit read rate from a device (e.g. --device-read-iops=/dev/sda:1000)
-
-**--device-write-bps**=[]
-   Limit write rate to a device (e.g. --device-write-bps=/dev/sda:1mb)
-
-**--device-write-iops**=[]
-   Limit write rate to a device (e.g. --device-write-iops=/dev/sda:1000)
-
-**--dns-search**=[]
-   Set custom DNS search domains (Use --dns-search=. if you don't wish to set the search domain)
-
-**--dns-option**=[]
-   Set custom DNS options
-
-**--dns**=[]
-   Set custom DNS servers
-
-   This option can be used to override the DNS
-configuration passed to the container. Typically this is necessary when the
-host DNS configuration is invalid for the container (e.g., 127.0.0.1). When this
-is the case the **--dns** flags is necessary for every run.
-
-**-e**, **--env**=[]
-   Set environment variables
-
-   This option allows you to specify arbitrary
-environment variables that are available for the process that will be launched
-inside of the container.
-
-**--entrypoint**=""
-   Overwrite the default ENTRYPOINT of the image
-
-   This option allows you to overwrite the default entrypoint of the image that
-is set in the Dockerfile. The ENTRYPOINT of an image is similar to a COMMAND
-because it specifies what executable to run when the container starts, but it is
-(purposely) more difficult to override. The ENTRYPOINT gives a container its
-default nature or behavior, so that when you set an ENTRYPOINT you can run the
-container as if it were that binary, complete with default options, and you can
-pass in more options via the COMMAND. But, sometimes an operator may want to run
-something else inside the container, so you can override the default ENTRYPOINT
-at runtime by using a **--entrypoint** and a string to specify the new
-ENTRYPOINT.
-
-**--env-file**=[]
-   Read in a line delimited file of environment variables
-
-**--expose**=[]
-   Expose a port, or a range of ports (e.g. --expose=3300-3310) informs Docker
-that the container listens on the specified network ports at runtime. Docker
-uses this information to interconnect containers using links and to set up port
-redirection on the host system.
-
-**--group-add**=[]
-   Add additional groups to run as
-
-**-h**, **--hostname**=""
-   Container host name
-
-   Sets the container host name that is available inside the container.
-
-**--help**
-   Print usage statement
-
-**--init**
-   Run an init inside the container that forwards signals and reaps processes
-
-**-i**, **--interactive**=*true*|*false*
-   Keep STDIN open even if not attached. The default is *false*.
-
-   When set to true, keep stdin open even if not attached. The default is false.
-
-**--ip**=""
-   Sets the container's interface IPv4 address (e.g., 172.23.0.9)
-
-   It can only be used in conjunction with **--network** for user-defined networks
-
-**--ip6**=""
-   Sets the container's interface IPv6 address (e.g., 2001:db8::1b99)
-
-   It can only be used in conjunction with **--network** for user-defined networks
-
-**--ipc**=""
-   Default is to create a private IPC namespace (POSIX SysV IPC) for the container
-                               'container:<name|id>': reuses another container shared memory, semaphores and message queues
-                               'host': use the host shared memory,semaphores and message queues inside the container.  Note: the host mode gives the container full access to local shared memory and is therefore considered insecure.
-
-**--isolation**="*default*"
-   Isolation specifies the type of isolation technology used by containers. Note
-that the default on Windows server is `process`, and the default on Windows client
-is `hyperv`. Linux only supports `default`.
-
-**-l**, **--label**=[]
-   Set metadata on the container (e.g., --label com.example.key=value)
-
-**--kernel-memory**=""
-   Kernel memory limit (format: `<number>[<unit>]`, where unit = b, k, m or g)
-
-   Constrains the kernel memory available to a container. If a limit of 0
-is specified (not using `--kernel-memory`), the container's kernel memory
-is not limited. If you specify a limit, it may be rounded up to a multiple
-of the operating system's page size and the value can be very large,
-millions of trillions.
-
-**--label-file**=[]
-   Read in a line delimited file of labels
-
-**--link**=[]
-   Add link to another container in the form of <name or id>:alias or just <name or id>
-in which case the alias will match the name
-
-   If the operator
-uses **--link** when starting the new client container, then the client
-container can access the exposed port via a private networking interface. Docker
-will set some environment variables in the client container to help indicate
-which interface and port to use.
-
-**--link-local-ip**=[]
-   Add one or more link-local IPv4/IPv6 addresses to the container's interface
-
-**--log-driver**="*json-file*|*syslog*|*journald*|*gelf*|*fluentd*|*awslogs*|*splunk*|*etwlogs*|*gcplogs*|*none*"
-  Logging driver for the container. Default is defined by daemon `--log-driver` flag.
-  **Warning**: the `docker logs` command works only for the `json-file` and
-  `journald` logging drivers.
-
-**--log-opt**=[]
-  Logging driver specific options.
-
-**-m**, **--memory**=""
-   Memory limit (format: <number>[<unit>], where unit = b, k, m or g)
-
-   Allows you to constrain the memory available to a container. If the host
-supports swap memory, then the **-m** memory setting can be larger than physical
-RAM. If a limit of 0 is specified (not using **-m**), the container's memory is
-not limited. The actual limit may be rounded up to a multiple of the operating
-system's page size (the value would be very large, that's millions of trillions).
-
-**--memory-reservation**=""
-   Memory soft limit (format: <number>[<unit>], where unit = b, k, m or g)
-
-   After setting memory reservation, when the system detects memory contention
-or low memory, containers are forced to restrict their consumption to their
-reservation. So you should always set the value below **--memory**, otherwise the
-hard limit will take precedence. By default, memory reservation will be the same
-as memory limit.
-
-**--memory-swap**="LIMIT"
-   A limit value equal to memory plus swap. Must be used with the  **-m**
-(**--memory**) flag. The swap `LIMIT` should always be larger than **-m**
-(**--memory**) value.  By default, the swap `LIMIT` will be set to double
-the value of --memory.
-
-   The format of `LIMIT` is `<number>[<unit>]`. Unit can be `b` (bytes),
-`k` (kilobytes), `m` (megabytes), or `g` (gigabytes). If you don't specify a
-unit, `b` is used. Set LIMIT to `-1` to enable unlimited swap.
-
-**--mac-address**=""
-   Container MAC address (e.g., 92:d0:c6:0a:29:33)
-
-   Remember that the MAC address in an Ethernet network must be unique.
-The IPv6 link-local address will be based on the device's MAC address
-according to RFC4862.
-
-**--mount**=[*[type=TYPE[,TYPE-SPECIFIC-OPTIONS]]*]
-   Attach a filesystem mount to the container
-
-   Current supported mount `TYPES` are `bind`, `volume`, and `tmpfs`.
-
-   e.g.
-
-   `type=bind,source=/path/on/host,destination=/path/in/container`
-
-   `type=volume,source=my-volume,destination=/path/in/container,volume-label="color=red",volume-label="shape=round"`
-
-   `type=tmpfs,tmpfs-size=512M,destination=/path/in/container`
-
-   Common Options:
-
-   * `src`, `source`: mount source spec for `bind` and `volume`. Mandatory for `bind`.
-   * `dst`, `destination`, `target`: mount destination spec.
-   * `ro`, `read-only`: `true` or `false` (default).
-
-   Options specific to `bind`:
-
-   * `bind-propagation`: `shared`, `slave`, `private`, `rshared`, `rslave`, or `rprivate`(default). See also `mount(2)`.
-   * `consistency`: `consistent`(default), `cached`, or `delegated`. Currently, only effective for Docker for Mac.
-
-   Options specific to `volume`:
-
-   * `volume-driver`: Name of the volume-driver plugin.
-   * `volume-label`: Custom metadata.
-   * `volume-nocopy`: `true`(default) or `false`. If set to `false`, the Engine copies existing files and directories under the mount-path into the volume, allowing the host to access them.
-   * `volume-opt`: specific to a given volume driver.
-
-   Options specific to `tmpfs`:
-
-   * `tmpfs-size`: Size of the tmpfs mount in bytes. Unlimited by default in Linux.
-   * `tmpfs-mode`: File mode of the tmpfs in octal. (e.g. `700` or `0700`.) Defaults to `1777` in Linux.
-
-**--name**=""
-   Assign a name to the container
-
-   The operator can identify a container in three ways:
-    UUID long identifier (“f78375b1c487e03c9438c729345e54db9d20cfa2ac1fc3494b6eb60872e74778”)
-    UUID short identifier (“f78375b1c487”)
-    Name (“jonah”)
-
-   The UUID identifiers come from the Docker daemon, and if a name is not assigned
-to the container with **--name** then the daemon will also generate a random
-string name. The name is useful when defining links (see **--link**) (or any
-other place you need to identify a container). This works for both background
-and foreground Docker containers.
-
-**--network**="*bridge*"
-   Set the Network mode for the container
-                               'bridge': create a network stack on the default Docker bridge
-                               'none': no networking
-                               'container:<name|id>': reuse another container's network stack
-                               'host': use the Docker host network stack. Note: the host mode gives the container full access to local system services such as D-bus and is therefore considered insecure.
-                               '<network-name>|<network-id>': connect to a user-defined network
-
-**--network-alias**=[]
-   Add network-scoped alias for the container
-
-**--oom-kill-disable**=*true*|*false*
-   Whether to disable OOM Killer for the container or not.
-
-**--oom-score-adj**=""
-   Tune the host's OOM preferences for containers (accepts -1000 to 1000)
-
-**-P**, **--publish-all**=*true*|*false*
-   Publish all exposed ports to random ports on the host interfaces. The default is *false*.
-
-   When set to true publish all exposed ports to the host interfaces. The
-default is false. If the operator uses -P (or -p) then Docker will make the
-exposed port accessible on the host and the ports will be available to any
-client that can reach the host. When using -P, Docker will bind any exposed
-port to a random port on the host within an *ephemeral port range* defined by
-`/proc/sys/net/ipv4/ip_local_port_range`. To find the mapping between the host
-ports and the exposed ports, use `docker port`.
-
-**-p**, **--publish**=[]
-   Publish a container's port, or range of ports, to the host.
-
-   Format: `ip:hostPort:containerPort | ip::containerPort | hostPort:containerPort | containerPort`
-Both hostPort and containerPort can be specified as a range of ports.
-When specifying ranges for both, the number of container ports in the range must match the number of host ports in the range.
-(e.g., `docker run -p 1234-1236:1222-1224 --name thisWorks -t busybox`
-but not `docker run -p 1230-1236:1230-1240 --name RangeContainerPortsBiggerThanRangeHostPorts -t busybox`)
-With ip: `docker run -p 127.0.0.1:$HOSTPORT:$CONTAINERPORT --name CONTAINER -t someimage`
-Use `docker port` to see the actual mapping: `docker port CONTAINER $CONTAINERPORT`
-
-**--pid**=""
-   Set the PID mode for the container
-   Default is to create a private PID namespace for the container
-                               'container:<name|id>': join another container's PID namespace
-                               'host': use the host's PID namespace for the container. Note: the host mode gives the container full access to local PID and is therefore considered insecure.
-
-**--userns**=""
-   Set the usernamespace mode for the container when `userns-remap` option is enabled.
-     **host**: use the host usernamespace and enable all privileged options (e.g., `pid=host` or `--privileged`).
-
-**--pids-limit**=""
-   Tune the container's pids limit. Set `-1` to have unlimited pids for the container.
-
-**--uts**=*host*
-   Set the UTS mode for the container
-     **host**: use the host's UTS namespace inside the container.
-     Note: the host mode gives the container access to changing the host's hostname and is therefore considered insecure.
-
-**--privileged**=*true*|*false*
-   Give extended privileges to this container. The default is *false*.
-
-   By default, Docker containers are
-“unprivileged” (=false) and cannot, for example, run a Docker daemon inside the
-Docker container. This is because by default a container is not allowed to
-access any devices. A “privileged” container is given access to all devices.
-
-   When the operator executes **docker run --privileged**, Docker will enable access
-to all devices on the host as well as set some configuration in AppArmor to
-allow the container nearly all the same access to the host as processes running
-outside of a container on the host.
-
-**--read-only**=*true*|*false*
-   Mount the container's root filesystem as read only.
-
-   By default a container will have its root filesystem writable allowing processes
-to write files anywhere.  By specifying the `--read-only` flag the container will have
-its root filesystem mounted as read only prohibiting any writes.
-
-**--restart**="*no*"
-   Restart policy to apply when a container exits (no, on-failure[:max-retry], always, unless-stopped).
-
-**--rm**=*true*|*false*
-   Automatically remove the container when it exits. The default is *false*.
-   `--rm` flag can work together with `-d`, and auto-removal will be done on daemon side. Note that it's
-incompatible with any restart policy other than `none`.
-
-**--security-opt**=[]
-   Security Options
-
-    "label=user:USER"   : Set the label user for the container
-    "label=role:ROLE"   : Set the label role for the container
-    "label=type:TYPE"   : Set the label type for the container
-    "label=level:LEVEL" : Set the label level for the container
-    "label=disable"     : Turn off label confinement for the container
-    "no-new-privileges" : Disable container processes from gaining additional privileges
-
-    "seccomp=unconfined" : Turn off seccomp confinement for the container
-    "seccomp=profile.json :  White listed syscalls seccomp Json file to be used as a seccomp filter
-
-    "apparmor=unconfined" : Turn off apparmor confinement for the container
-    "apparmor=your-profile" : Set the apparmor confinement profile for the container
-
-**--storage-opt**=[]
-   Storage driver options per container
-
-   $ docker run -it --storage-opt size=120G fedora /bin/bash
-
-   This (size) will allow to set the container rootfs size to 120G at creation time.
-   This option is only available for the `devicemapper`, `btrfs`, `overlay2`  and `zfs` graph drivers.
-   For the `devicemapper`, `btrfs` and `zfs` storage drivers, user cannot pass a size less than the Default BaseFS Size.
-   For the `overlay2` storage driver, the size option is only available if the backing fs is `xfs` and mounted with the `pquota` mount option.
-   Under these conditions, user can pass any size less then the backing fs size.
-
-**--stop-signal**=*SIGTERM*
-  Signal to stop a container. Default is SIGTERM.
-
-**--stop-timeout**=*10*
-  Timeout (in seconds) to stop a container. Default is 10.
-
-**--shm-size**=""
-   Size of `/dev/shm`. The format is `<number><unit>`.
-   `number` must be greater than `0`.  Unit is optional and can be `b` (bytes), `k` (kilobytes), `m`(megabytes), or `g` (gigabytes).
-   If you omit the unit, the system uses bytes. If you omit the size entirely, the system uses `64m`.
-
-**--sysctl**=SYSCTL
-  Configure namespaced kernel parameters at runtime
-
-  IPC Namespace - current sysctls allowed:
-
-  kernel.msgmax, kernel.msgmnb, kernel.msgmni, kernel.sem, kernel.shmall, kernel.shmmax, kernel.shmmni, kernel.shm_rmid_forced
-  Sysctls beginning with fs.mqueue.*
-
-  If you use the `--ipc=host` option these sysctls will not be allowed.
-
-  Network Namespace - current sysctls allowed:
-      Sysctls beginning with net.*
-
-  If you use the `--network=host` option these sysctls will not be allowed.
-
-**--sig-proxy**=*true*|*false*
-   Proxy received signals to the process (non-TTY mode only). SIGCHLD, SIGSTOP, and SIGKILL are not proxied. The default is *true*.
-
-**--memory-swappiness**=""
-   Tune a container's memory swappiness behavior. Accepts an integer between 0 and 100.
-
-**-t**, **--tty**=*true*|*false*
-   Allocate a pseudo-TTY. The default is *false*.
-
-   When set to true Docker can allocate a pseudo-tty and attach to the standard
-input of any container. This can be used, for example, to run a throwaway
-interactive shell. The default is false.
-
-The **-t** option is incompatible with a redirection of the docker client
-standard input.
-
-**--tmpfs**=[] Create a tmpfs mount
-
-   Mount a temporary filesystem (`tmpfs`) mount into a container, for example:
-
-   $ docker run -d --tmpfs /tmp:rw,size=787448k,mode=1777 my_image
-
-   This command mounts a `tmpfs` at `/tmp` within the container.  The supported mount
-options are the same as the Linux default `mount` flags. If you do not specify
-any options, the systems uses the following options:
-`rw,noexec,nosuid,nodev,size=65536k`.
-
-   See also `--mount`, which is the successor of `--tmpfs` and `--volume`.
-   Even though there is no plan to deprecate `--tmpfs`, usage of `--mount` is recommended.
-
-**-u**, **--user**=""
-   Sets the username or UID used and optionally the groupname or GID for the specified command.
-
-   The followings examples are all valid:
-   --user [user | user:group | uid | uid:gid | user:gid | uid:group ]
-
-   Without this argument the command will be run as root in the container.
-
-**--ulimit**=[]
-    Ulimit options
-
-**-v**|**--volume**[=*[[HOST-DIR:]CONTAINER-DIR[:OPTIONS]]*]
-   Create a bind mount. If you specify, ` -v /HOST-DIR:/CONTAINER-DIR`, Docker
-   bind mounts `/HOST-DIR` in the host to `/CONTAINER-DIR` in the Docker
-   container. If 'HOST-DIR' is omitted,  Docker automatically creates the new
-   volume on the host.  The `OPTIONS` are a comma delimited list and can be:
-
-   * [rw|ro]
-   * [z|Z]
-   * [`[r]shared`|`[r]slave`|`[r]private`]
-   * [`delegated`|`cached`|`consistent`]
-   * [nocopy]
-
-The `CONTAINER-DIR` must be an absolute path such as `/src/docs`. The `HOST-DIR`
-can be an absolute path or a `name` value. A `name` value must start with an
-alphanumeric character, followed by `a-z0-9`, `_` (underscore), `.` (period) or
-`-` (hyphen). An absolute path starts with a `/` (forward slash).
-
-If you supply a `HOST-DIR` that is an absolute path,  Docker bind-mounts to the
-path you specify. If you supply a `name`, Docker creates a named volume by that
-`name`. For example, you can specify either `/foo` or `foo` for a `HOST-DIR`
-value. If you supply the `/foo` value, Docker creates a bind-mount. If you
-supply the `foo` specification, Docker creates a named volume.
-
-You can specify multiple  **-v** options to mount one or more mounts to a
-container. To use these same mounts in other containers, specify the
-**--volumes-from** option also.
-
-You can supply additional options for each bind-mount following an additional
-colon.  A `:ro` or `:rw` suffix mounts a volume in read-only or read-write
-mode, respectively. By default, volumes are mounted in read-write mode.
-You can also specify the consistency requirement for the mount, either
-`:consistent` (the default), `:cached`, or `:delegated`.  Multiple options are
-separated by commas, e.g. `:ro,cached`.
-
-Labeling systems like SELinux require that proper labels are placed on volume
-content mounted into a container. Without a label, the security system might
-prevent the processes running inside the container from using the content. By
-default, Docker does not change the labels set by the OS.
-
-To change a label in the container context, you can add either of two suffixes
-`:z` or `:Z` to the volume mount. These suffixes tell Docker to relabel file
-objects on the shared volumes. The `z` option tells Docker that two containers
-share the volume content. As a result, Docker labels the content with a shared
-content label. Shared volume labels allow all containers to read/write content.
-The `Z` option tells Docker to label the content with a private unshared label.
-Only the current container can use a private volume.
-
-By default bind mounted volumes are `private`. That means any mounts done
-inside container will not be visible on host and vice-a-versa. One can change
-this behavior by specifying a volume mount propagation property. Making a
-volume `shared` mounts done under that volume inside container will be
-visible on host and vice-a-versa. Making a volume `slave` enables only one
-way mount propagation and that is mounts done on host under that volume
-will be visible inside container but not the other way around.
-
-To control mount propagation property of volume one can use `:[r]shared`,
-`:[r]slave` or `:[r]private` propagation flag. Propagation property can
-be specified only for bind mounted volumes and not for internal volumes or
-named volumes. For mount propagation to work source mount point (mount point
-where source dir is mounted on) has to have right propagation properties. For
-shared volumes, source mount point has to be shared. And for slave volumes,
-source mount has to be either shared or slave.
-
-Use `df <source-dir>` to figure out the source mount and then use
-`findmnt -o TARGET,PROPAGATION <source-mount-dir>` to figure out propagation
-properties of source mount. If `findmnt` utility is not available, then one
-can look at mount entry for source mount point in `/proc/self/mountinfo`. Look
-at `optional fields` and see if any propagation properties are specified.
-`shared:X` means mount is `shared`, `master:X` means mount is `slave` and if
-nothing is there that means mount is `private`.
-
-To change propagation properties of a mount point use `mount` command. For
-example, if one wants to bind mount source directory `/foo` one can do
-`mount --bind /foo /foo` and `mount --make-private --make-shared /foo`. This
-will convert /foo into a `shared` mount point. Alternatively one can directly
-change propagation properties of source mount. Say `/` is source mount for
-`/foo`, then use `mount --make-shared /` to convert `/` into a `shared` mount.
-
-> **Note**:
-> When using systemd to manage the Docker daemon's start and stop, in the systemd
-> unit file there is an option to control mount propagation for the Docker daemon
-> itself, called `MountFlags`. The value of this setting may cause Docker to not
-> see mount propagation changes made on the mount point. For example, if this value
-> is `slave`, you may not be able to use the `shared` or `rshared` propagation on
-> a volume.
-
-To disable automatic copying of data from the container path to the volume, use
-the `nocopy` flag. The `nocopy` flag can be set on bind mounts and named volumes.
-
-See also `--mount`, which is the successor of `--tmpfs` and `--volume`.
-Even though there is no plan to deprecate `--volume`, usage of `--mount` is recommended.
-
-**--volume-driver**=""
-   Container's volume driver. This driver creates volumes specified either from
-   a Dockerfile's `VOLUME` instruction or from the `docker run -v` flag.
-   See **docker-volume-create(1)** for full details.
-
-**--volumes-from**=[]
-   Mount volumes from the specified container(s)
-
-   Mounts already mounted volumes from a source container onto another
-   container. You must supply the source's container-id. To share
-   a volume, use the **--volumes-from** option when running
-   the target container. You can share volumes even if the source container
-   is not running.
-
-   By default, Docker mounts the volumes in the same mode (read-write or
-   read-only) as it is mounted in the source container. Optionally, you
-   can change this by suffixing the container-id with either the `:ro` or
-   `:rw ` keyword.
-
-   If the location of the volume from the source container overlaps with
-   data residing on a target container, then the volume hides
-   that data on the target.
-
-**-w**, **--workdir**=""
-   Working directory inside the container
-
-   The default working directory for
-running binaries within a container is the root directory (/). The developer can
-set a different default with the Dockerfile WORKDIR instruction. The operator
-can override the working directory by using the **-w** option.
-
-# Exit Status
-
-The exit code from `docker run` gives information about why the container
-failed to run or why it exited.  When `docker run` exits with a non-zero code,
-the exit codes follow the `chroot` standard, see below:
-
-**_125_** if the error is with Docker daemon **_itself_** 
-
-    $ docker run --foo busybox; echo $?
-    # flag provided but not defined: --foo
-      See 'docker run --help'.
-      125
-
-**_126_** if the **_contained command_** cannot be invoked
-
-    $ docker run busybox /etc; echo $?
-    # exec: "/etc": permission denied
-      docker: Error response from daemon: Contained command could not be invoked
-      126
-
-**_127_** if the **_contained command_** cannot be found
-
-    $ docker run busybox foo; echo $?
-    # exec: "foo": executable file not found in $PATH
-      docker: Error response from daemon: Contained command not found or does not exist
-      127
-
-**_Exit code_** of **_contained command_** otherwise 
-    
-    $ docker run busybox /bin/sh -c 'exit 3' 
-    # 3
-
-# EXAMPLES
-
-## Running container in read-only mode
-
-During container image development, containers often need to write to the image
-content.  Installing packages into /usr, for example.  In production,
-applications seldom need to write to the image.  Container applications write
-to volumes if they need to write to file systems at all.  Applications can be
-made more secure by running them in read-only mode using the --read-only switch.
-This protects the containers image from modification. Read only containers may
-still need to write temporary data.  The best way to handle this is to mount
-tmpfs directories on /run and /tmp.
-
-    # docker run --read-only --tmpfs /run --tmpfs /tmp -i -t fedora /bin/bash
-
-## Exposing log messages from the container to the host's log
-
-If you want messages that are logged in your container to show up in the host's
-syslog/journal then you should bind mount the /dev/log directory as follows.
-
-    # docker run -v /dev/log:/dev/log -i -t fedora /bin/bash
-
-From inside the container you can test this by sending a message to the log.
-
-    (bash)# logger "Hello from my container"
-
-Then exit and check the journal.
-
-    # exit
-
-    # journalctl -b | grep Hello
-
-This should list the message sent to logger.
-
-## Attaching to one or more from STDIN, STDOUT, STDERR
-
-If you do not specify -a then Docker will attach everything (stdin,stdout,stderr)
-. You can specify to which of the three standard streams (stdin, stdout, stderr)
-you'd like to connect instead, as in:
-
-    # docker run -a stdin -a stdout -i -t fedora /bin/bash
-
-## Sharing IPC between containers
-
-Using shm_server.c available here: https://www.cs.cf.ac.uk/Dave/C/node27.html
-
-Testing `--ipc=host` mode:
-
-Host shows a shared memory segment with 7 pids attached, happens to be from httpd:
-
-```
- $ sudo ipcs -m
-
- ------ Shared Memory Segments --------
- key        shmid      owner      perms      bytes      nattch     status      
- 0x01128e25 0          root       600        1000       7                       
-```
-
-Now run a regular container, and it correctly does NOT see the shared memory segment from the host:
-
-```
- $ docker run -it shm ipcs -m
-
- ------ Shared Memory Segments --------
- key        shmid      owner      perms      bytes      nattch     status      
-```
-
-Run a container with the new `--ipc=host` option, and it now sees the shared memory segment from the host httpd:
-
- ```
- $ docker run -it --ipc=host shm ipcs -m
-
- ------ Shared Memory Segments --------
- key        shmid      owner      perms      bytes      nattch     status      
- 0x01128e25 0          root       600        1000       7                   
-```
-Testing `--ipc=container:CONTAINERID` mode:
-
-Start a container with a program to create a shared memory segment:
-```
- $ docker run -it shm bash
- $ sudo shm/shm_server &
- $ sudo ipcs -m
-
- ------ Shared Memory Segments --------
- key        shmid      owner      perms      bytes      nattch     status      
- 0x0000162e 0          root       666        27         1                       
-```
-Create a 2nd container correctly shows no shared memory segment from 1st container:
-```
- $ docker run shm ipcs -m
-
- ------ Shared Memory Segments --------
- key        shmid      owner      perms      bytes      nattch     status      
-```
-
-Create a 3rd container using the new --ipc=container:CONTAINERID option, now it shows the shared memory segment from the first:
-
-```
- $ docker run -it --ipc=container:ed735b2264ac shm ipcs -m
- $ sudo ipcs -m
-
- ------ Shared Memory Segments --------
- key        shmid      owner      perms      bytes      nattch     status      
- 0x0000162e 0          root       666        27         1
-```
-
-## Linking Containers
-
-> **Note**: This section describes linking between containers on the
-> default (bridge) network, also known as "legacy links". Using `--link`
-> on user-defined networks uses the DNS-based discovery, which does not add
-> entries to `/etc/hosts`, and does not set environment variables for
-> discovery.
-
-The link feature allows multiple containers to communicate with each other. For
-example, a container whose Dockerfile has exposed port 80 can be run and named
-as follows:
-
-    # docker run --name=link-test -d -i -t fedora/httpd
-
-A second container, in this case called linker, can communicate with the httpd
-container, named link-test, by running with the **--link=<name>:<alias>**
-
-    # docker run -t -i --link=link-test:lt --name=linker fedora /bin/bash
-
-Now the container linker is linked to container link-test with the alias lt.
-Running the **env** command in the linker container shows environment variables
- with the LT (alias) context (**LT_**)
-
-    # env
-    HOSTNAME=668231cb0978
-    TERM=xterm
-    LT_PORT_80_TCP=tcp://172.17.0.3:80
-    LT_PORT_80_TCP_PORT=80
-    LT_PORT_80_TCP_PROTO=tcp
-    LT_PORT=tcp://172.17.0.3:80
-    PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin
-    PWD=/
-    LT_NAME=/linker/lt
-    SHLVL=1
-    HOME=/
-    LT_PORT_80_TCP_ADDR=172.17.0.3
-    _=/usr/bin/env
-
-When linking two containers Docker will use the exposed ports of the container
-to create a secure tunnel for the parent to access.
-
-If a container is connected to the default bridge network and `linked`
-with other containers, then the container's `/etc/hosts` file is updated
-with the linked container's name.
-
-> **Note** Since Docker may live update the container's `/etc/hosts` file, there
-may be situations when processes inside the container can end up reading an
-empty or incomplete `/etc/hosts` file. In most cases, retrying the read again
-should fix the problem.
-
-
-## Mapping Ports for External Usage
-
-The exposed port of an application can be mapped to a host port using the **-p**
-flag. For example, an httpd port 80 can be mapped to the host port 8080 using the
-following:
-
-    # docker run -p 8080:80 -d -i -t fedora/httpd
-
-## Creating and Mounting a Data Volume Container
-
-Many applications require the sharing of persistent data across several
-containers. Docker allows you to create a Data Volume Container that other
-containers can mount from. For example, create a named container that contains
-directories /var/volume1 and /tmp/volume2. The image will need to contain these
-directories so a couple of RUN mkdir instructions might be required for you
-fedora-data image:
-
-    # docker run --name=data -v /var/volume1 -v /tmp/volume2 -i -t fedora-data true
-    # docker run --volumes-from=data --name=fedora-container1 -i -t fedora bash
-
-Multiple --volumes-from parameters will bring together multiple data volumes from
-multiple containers. And it's possible to mount the volumes that came from the
-DATA container in yet another container via the fedora-container1 intermediary
-container, allowing to abstract the actual data source from users of that data:
-
-    # docker run --volumes-from=fedora-container1 --name=fedora-container2 -i -t fedora bash
-
-## Mounting External Volumes
-
-To mount a host directory as a container volume, specify the absolute path to
-the directory and the absolute path for the container directory separated by a
-colon:
-
-    # docker run -v /var/db:/data1 -i -t fedora bash
-
-When using SELinux, be aware that the host has no knowledge of container SELinux
-policy. Therefore, in the above example, if SELinux policy is enforced, the
-`/var/db` directory is not writable to the container. A "Permission Denied"
-message will occur and an avc: message in the host's syslog.
-
-
-To work around this, at time of writing this man page, the following command
-needs to be run in order for the proper SELinux policy type label to be attached
-to the host directory:
-
-    # chcon -Rt svirt_sandbox_file_t /var/db
-
-
-Now, writing to the /data1 volume in the container will be allowed and the
-changes will also be reflected on the host in /var/db.
-
-## Using alternative security labeling
-
-You can override the default labeling scheme for each container by specifying
-the `--security-opt` flag. For example, you can specify the MCS/MLS level, a
-requirement for MLS systems. Specifying the level in the following command
-allows you to share the same content between containers.
-
-    # docker run --security-opt label=level:s0:c100,c200 -i -t fedora bash
-
-An MLS example might be:
-
-    # docker run --security-opt label=level:TopSecret -i -t rhel7 bash
-
-To disable the security labeling for this container versus running with the
-`--permissive` flag, use the following command:
-
-    # docker run --security-opt label=disable -i -t fedora bash
-
-If you want a tighter security policy on the processes within a container,
-you can specify an alternate type for the container. You could run a container
-that is only allowed to listen on Apache ports by executing the following
-command:
-
-    # docker run --security-opt label=type:svirt_apache_t -i -t centos bash
-
-Note:
-
-You would have to write policy defining a `svirt_apache_t` type.
-
-## Setting device weight
-
-If you want to set `/dev/sda` device weight to `200`, you can specify the device
-weight by `--blkio-weight-device` flag. Use the following command:
-
-    # docker run -it --blkio-weight-device "/dev/sda:200" ubuntu
-
-## Specify isolation technology for container (--isolation)
-
-This option is useful in situations where you are running Docker containers on
-Microsoft Windows. The `--isolation <value>` option sets a container's isolation
-technology. On Linux, the only supported is the `default` option which uses
-Linux namespaces. These two commands are equivalent on Linux:
-
-```
-$ docker run -d busybox top
-$ docker run -d --isolation default busybox top
-```
-
-On Microsoft Windows, can take any of these values:
-
-* `default`: Use the value specified by the Docker daemon's `--exec-opt` . If the `daemon` does not specify an isolation technology, Microsoft Windows uses `process` as its default value.
-* `process`: Namespace isolation only.
-* `hyperv`: Hyper-V hypervisor partition-based isolation.
-
-In practice, when running on Microsoft Windows without a `daemon` option set,  these two commands are equivalent:
-
-```
-$ docker run -d --isolation default busybox top
-$ docker run -d --isolation process busybox top
-```
-
-If you have set the `--exec-opt isolation=hyperv` option on the Docker `daemon`, any of these commands also result in `hyperv` isolation:
-
-```
-$ docker run -d --isolation default busybox top
-$ docker run -d --isolation hyperv busybox top
-```
-
-## Setting Namespaced Kernel Parameters (Sysctls)
-
-The `--sysctl` sets namespaced kernel parameters (sysctls) in the
-container. For example, to turn on IP forwarding in the containers
-network namespace, run this command:
-
-    $ docker run --sysctl net.ipv4.ip_forward=1 someimage
-
-Note:
-
-Not all sysctls are namespaced. Docker does not support changing sysctls
-inside of a container that also modify the host system. As the kernel 
-evolves we expect to see more sysctls become namespaced.
-
-See the definition of the `--sysctl` option above for the current list of 
-supported sysctls.

-# DESCRIPTION
-**dockerd** is used for starting the Docker daemon (i.e., to command the daemon
-to manage images, containers etc).  So **dockerd** is a server, as a daemon.
-
-To run the Docker daemon you can specify **dockerd**.
-You can check the daemon options using **dockerd --help**.
-Daemon options should be specified after the **dockerd** keyword in the
-following format.
-
-**dockerd [OPTIONS]**
-
-# OPTIONS
-
-**--add-runtime**=[]
-  Runtimes can be registered with the daemon either via the
-configuration file or using the `--add-runtime` command line argument.
-
-  The following is an example adding 2 runtimes via the configuration:
-
-```json
-{
-	"default-runtime": "runc",
-	"runtimes": {
-		"runc": {
-			"path": "runc"
-		},
-		"custom": {
-			"path": "/usr/local/bin/my-runc-replacement",
-			"runtimeArgs": [
-				"--debug"
-			]
-		}
-	}
-}
-```
-
-  This is the same example via the command line:
-
-```bash
-$ sudo dockerd --add-runtime runc=runc --add-runtime custom=/usr/local/bin/my-runc-replacement
-```
-
-  **Note**: defining runtime arguments via the command line is not supported.
-
-**--allow-nondistributable-artifacts**=[]
-  Push nondistributable artifacts to the specified registries.
-
-  List can contain elements with CIDR notation to specify a whole subnet.
-
-  This option is useful when pushing images containing nondistributable
-  artifacts to a registry on an air-gapped network so hosts on that network can
-  pull the images without connecting to another server.
-
-  **Warning**: Nondistributable artifacts typically have restrictions on how
-  and where they can be distributed and shared. Only use this feature to push
-  artifacts to private registries and ensure that you are in compliance with
-  any terms that cover redistributing nondistributable artifacts.
-
-**--api-cors-header**=""
-  Set CORS headers in the Engine API. Default is cors disabled. Give urls like
-  "http://foo, http://bar, ...". Give "*" to allow all.
-
-**--authorization-plugin**=""
-  Set authorization plugins to load
-
-**-b**, **--bridge**=""
-  Attach containers to a pre\-existing network bridge; use 'none' to disable
-  container networking
-
-**--bip**=""
-  Use the provided CIDR notation address for the dynamically created bridge
-  (docker0); Mutually exclusive of \-b
-
-**--cgroup-parent**=""

-  driver and "system.slice" for systemd cgroup driver.
-
-**--cluster-store**=""
-  URL of the distributed storage backend
-
-**--cluster-advertise**=""
-  Specifies the 'host:port' or `interface:port` combination that this
-  particular daemon instance should use when advertising itself to the cluster.
-  The daemon is reached through this value.
-
-**--cluster-store-opt**=""
-  Specifies options for the Key/Value store.
-
-**--config-file**="/etc/docker/daemon.json"
-  Specifies the JSON file path to load the configuration from.
-
-**--containerd**=""
-  Path to containerd socket.
-
-**--data-root**=""
-  Path to the directory used to store persisted Docker data such as
-  configuration for resources, swarm cluster state, and filesystem data for
-  images, containers, and local volumes. Default is `/var/lib/docker`.
-
-**-D**, **--debug**=*true*|*false*
-  Enable debug mode. Default is false.
-
-**--default-gateway**=""
-  IPv4 address of the container default gateway; this address must be part of
-  the bridge subnet (which is defined by \-b or \--bip)
-
-**--default-gateway-v6**=""
-  IPv6 address of the container default gateway
-
-**--default-runtime**="runc"
-  Set default runtime if there're more than one specified by `--add-runtime`.
-
-**--default-shm-size**=*64MiB*
-  Set the daemon-wide default shm size for containers. Default is `64MiB`.
-
-**--default-ulimit**=[]
-  Default ulimits for containers.
-
-**--disable-legacy-registry**=*true*|*false*
-  Disable contacting legacy registries. Default is `true`.
-
-**--dns**=""
-  Force Docker to use specific DNS servers
-
-**--dns-opt**=""
-  DNS options to use.
-
-**--dns-search**=[]
-  DNS search domains to use.
-
-**--exec-opt**=[]
-  Set runtime execution options. See RUNTIME EXECUTION OPTIONS.
-
-**--exec-root**=""
-  Path to use as the root of the Docker execution state files. Default is
-  `/var/run/docker`.
-
-**--experimental**=""
-  Enable the daemon experimental features.
-
-**--fixed-cidr**=""
-  IPv4 subnet for fixed IPs (e.g., 10.20.0.0/16); this subnet must be nested in
-  the bridge subnet (which is defined by \-b or \-\-bip).
-
-**--fixed-cidr-v6**=""
-  IPv6 subnet for global IPv6 addresses (e.g., 2a00:1450::/64)
-
-**-G**, **--group**=""
-  Group to assign the unix socket specified by -H when running in daemon mode.
-  use '' (the empty string) to disable setting of a group. Default is `docker`.
-
-**-H**, **--host**=[*unix:///var/run/docker.sock*]: tcp://[host:port] to bind or
-unix://[/path/to/socket] to use.
-  The socket(s) to bind to in daemon mode specified using one or more
-  tcp://host:port, unix:///path/to/socket, fd://* or fd://socketfd.
-
-**--help**
-  Print usage statement
-
-**--icc**=*true*|*false*
-  Allow unrestricted inter\-container and Docker daemon host communication. If
-  disabled, containers can still be linked together using the **--link** option
-  (see **docker-run(1)**). Default is true.
-
-**--init**
-  Run an init process inside containers for signal forwarding and process
-  reaping.
-
-**--init-path**
-  Path to the docker-init binary.
-
-**--insecure-registry**=[]
-  Enable insecure registry communication, i.e., enable un-encrypted and/or
-  untrusted communication.
-
-  List of insecure registries can contain an element with CIDR notation to
-  specify a whole subnet. Insecure registries accept HTTP and/or accept HTTPS
-  with certificates from unknown CAs.
-
-  Enabling `--insecure-registry` is useful when running a local registry.
-  However, because its use creates security vulnerabilities it should ONLY be
-  enabled for testing purposes.  For increased security, users should add their
-  CA to their system's list of trusted CAs instead of using
-  `--insecure-registry`.
-
-**--ip**=""
-  Default IP address to use when binding container ports. Default is `0.0.0.0`.
-
-**--ip-forward**=*true*|*false*
-  Enables IP forwarding on the Docker host. The default is `true`. This flag
-  interacts with the IP forwarding setting on your host system's kernel. If
-  your system has IP forwarding disabled, this setting enables it. If your
-  system has IP forwarding enabled, setting this flag to `--ip-forward=false`
-  has no effect.
-
-  This setting will also enable IPv6 forwarding if you have both
-  `--ip-forward=true` and `--fixed-cidr-v6` set. Note that this may reject
-  Router Advertisements and interfere with the host's existing IPv6
-  configuration. For more information, please consult the documentation about
-  "Advanced Networking - IPv6".
-
-**--ip-masq**=*true*|*false*
-  Enable IP masquerading for bridge's IP range. Default is true.
-
-**--iptables**=*true*|*false*
-  Enable Docker's addition of iptables rules. Default is true.
-
-**--ipv6**=*true*|*false*
-  Enable IPv6 support. Default is false. Docker will create an IPv6-enabled
-  bridge with address fe80::1 which will allow you to create IPv6-enabled
-  containers. Use together with `--fixed-cidr-v6` to provide globally routable
-  IPv6 addresses. IPv6 forwarding will be enabled if not used with
-  `--ip-forward=false`. This may collide with your host's current IPv6
-  settings. For more information please consult the documentation about
-  "Advanced Networking - IPv6".
-
-**--isolation**="*default*"
-   Isolation specifies the type of isolation technology used by containers.
-   Note that the default on Windows server is `process`, and the default on
-   Windows client is `hyperv`. Linux only supports `default`.
-
-**-l**, **--log-level**="*debug*|*info*|*warn*|*error*|*fatal*"
-  Set the logging level. Default is `info`.
-
-**--label**="[]"
-  Set key=value labels to the daemon (displayed in `docker info`)
-
-**--live-restore**=*false*
-  Enable live restore of running containers when the daemon starts so that they
-  are not restarted. This option is applicable only for docker daemon running
-  on Linux host.
-
-**--log-driver**="*json-file*|*syslog*|*journald*|*gelf*|*fluentd*|*awslogs*|*splunk*|*etwlogs*|*gcplogs*|*none*"
-  Default driver for container logs. Default is `json-file`.
-  **Warning**: `docker logs` command works only for `json-file` logging driver.
-
-**--log-opt**=[]
-  Logging driver specific options.
-
-**--mtu**=*0*
-  Set the containers network mtu. Default is `0`.
-
-**--max-concurrent-downloads**=*3*
-  Set the max concurrent downloads for each pull. Default is `3`.
-
-**--max-concurrent-uploads**=*5*
-  Set the max concurrent uploads for each push. Default is `5`.
-
-**-p**, **--pidfile**=""
-  Path to use for daemon PID file. Default is `/var/run/docker.pid`
-
-**--raw-logs**
-  Output daemon logs in full timestamp format without ANSI coloring. If this
-  flag is not set, the daemon outputs condensed, colorized logs if a terminal
-  is detected, or full ("raw") output otherwise.
-
-**--registry-mirror**=*<scheme>://<host>*
-  Prepend a registry mirror to be used for image pulls. May be specified
-  multiple times.
-
-**-s**, **--storage-driver**=""
-  Force the Docker runtime to use a specific storage driver.
-
-**--seccomp-profile**=""
-  Path to seccomp profile.
-
-**--selinux-enabled**=*true*|*false*
-  Enable selinux support. Default is false.
-
-**--shutdown-timeout**=*15*
-  Set the shutdown timeout value in seconds. Default is `15`.
-
-**--storage-opt**=[]
-  Set storage driver options. See STORAGE DRIVER OPTIONS.
-
-**--swarm-default-advertise-addr**=*IP|INTERFACE*
-  Set default address or interface for swarm to advertise as its
-  externally-reachable address to other cluster members. This can be a
-  hostname, an IP address, or an interface such as `eth0`. A port cannot be
-  specified with this option.
-
-**--tls**=*true*|*false*
-  Use TLS; implied by --tlsverify. Default is false.
-
-**--tlscacert**=*~/.docker/ca.pem*
-  Trust certs signed only by this CA.
-
-**--tlscert**=*~/.docker/cert.pem*
-  Path to TLS certificate file.
-
-**--tlskey**=*~/.docker/key.pem*
-  Path to TLS key file.
-
-**--tlsverify**=*true*|*false*
-  Use TLS and verify the remote (daemon: verify client, client: verify daemon).
-  Default is false.
-
-**--userland-proxy**=*true*|*false*
-  Rely on a userland proxy implementation for inter-container and
-  outside-to-container loopback communications. Default is true.
-
-**--userland-proxy-path**=""
-  Path to the userland proxy binary.
-
-**--userns-remap**=*default*|*uid:gid*|*user:group*|*user*|*uid*
-  Enable user namespaces for containers on the daemon. Specifying "default"
-  will cause a new user and group to be created to handle UID and GID range
-  remapping for the user namespace mappings used for contained processes.
-  Specifying a user (or uid) and optionally a group (or gid) will cause the
-  daemon to lookup the user and group's subordinate ID ranges for use as the
-  user namespace mappings for contained processes.
-
-# STORAGE DRIVER OPTIONS
-
-Docker uses storage backends (known as "graphdrivers" in the Docker
-internals) to create writable containers from images.  Many of these
-backends use operating system level technologies and can be
-configured.
-
-Specify options to the storage backend with **--storage-opt** flags. The
-backends that currently take options are *devicemapper*, *zfs* and *btrfs*.
-Options for *devicemapper* are prefixed with *dm*, options for *zfs*
-start with *zfs* and options for *btrfs* start with *btrfs*.
-
-Specifically for devicemapper, the default is a "loopback" model which
-requires no pre-configuration, but is extremely inefficient.  Do not
-use it in production.
-
-To make the best use of Docker with the devicemapper backend, you must
-have a recent version of LVM.  Use `lvm` to create a thin pool; for
-more information see `man lvmthin`.  Then, use `--storage-opt
-dm.thinpooldev` to tell the Docker engine to use that pool for
-allocating images and container snapshots.
-
-## Devicemapper options
-
-#### dm.thinpooldev
-
-Specifies a custom block storage device to use for the thin pool.
-
-If using a block device for device mapper storage, it is best to use `lvm`
-to create and manage the thin-pool volume. This volume is then handed to Docker
-to exclusively create snapshot volumes needed for images and containers.
-
-Managing the thin-pool outside of Engine makes for the most feature-rich
-method of having Docker utilize device mapper thin provisioning as the
-backing storage for Docker containers. The highlights of the lvm-based
-thin-pool management feature include: automatic or interactive thin-pool
-resize support, dynamically changing thin-pool features, automatic thinp
-metadata checking when lvm activates the thin-pool, etc.
-
-As a fallback if no thin pool is provided, loopback files are
-created. Loopback is very slow, but can be used without any
-pre-configuration of storage. It is strongly recommended that you do
-not use loopback in production. Ensure your Engine daemon has a
-`--storage-opt dm.thinpooldev` argument provided.
-
-Example use:
-
-   $ dockerd \
-         --storage-opt dm.thinpooldev=/dev/mapper/thin-pool
-
-#### dm.directlvm_device
-
-As an alternative to manually creating a thin pool as above, Docker can
-automatically configure a block device for you.
-
-Example use:
-
-   $ dockerd \
-         --storage-opt dm.directlvm_device=/dev/xvdf
-
-##### dm.thinp_percent
-
-Sets the percentage of passed in block device to use for storage.
-
-###### Example:
-
-   $ sudo dockerd \
-        --storage-opt dm.thinp_percent=95
-
-##### `dm.thinp_metapercent`
-
-Sets the percentage of the passed in block device to use for metadata storage.
-
-###### Example:
-
-   $ sudo dockerd \
-         --storage-opt dm.thinp_metapercent=1
-
-##### dm.thinp_autoextend_threshold
-
-Sets the value of the percentage of space used before `lvm` attempts to
-autoextend the available space [100 = disabled]
-
-###### Example:
-
-   $ sudo dockerd \
-         --storage-opt dm.thinp_autoextend_threshold=80
-
-##### dm.thinp_autoextend_percent
-
-Sets the value percentage value to increase the thin pool by when when `lvm`
-attempts to autoextend the available space [100 = disabled]
-
-###### Example:
-
-   $ sudo dockerd \
-         --storage-opt dm.thinp_autoextend_percent=20
-
-#### dm.basesize
-
-Specifies the size to use when creating the base device, which limits
-the size of images and containers. The default value is 10G. Note,
-thin devices are inherently "sparse", so a 10G device which is mostly
-empty doesn't use 10 GB of space on the pool. However, the filesystem
-will use more space for base images the larger the device
-is.
-
-The base device size can be increased at daemon restart which will allow
-all future images and containers (based on those new images) to be of the
-new base device size.
-
-Example use: `dockerd --storage-opt dm.basesize=50G`
-
-This will increase the base device size to 50G. The Docker daemon will throw an
-error if existing base device size is larger than 50G. A user can use
-this option to expand the base device size however shrinking is not permitted.
-
-This value affects the system-wide "base" empty filesystem that may already
-be initialized and inherited by pulled images. Typically, a change to this
-value requires additional steps to take effect:
-
-        $ sudo service docker stop
-        $ sudo rm -rf /var/lib/docker
-        $ sudo service docker start
-
-Example use: `dockerd --storage-opt dm.basesize=20G`
-
-#### dm.fs
-
-Specifies the filesystem type to use for the base device. The
-supported options are `ext4` and `xfs`. The default is `ext4`.
-
-Example use: `dockerd --storage-opt dm.fs=xfs`
-
-#### dm.mkfsarg
-
-Specifies extra mkfs arguments to be used when creating the base device.
-
-Example use: `dockerd --storage-opt "dm.mkfsarg=-O ^has_journal"`
-
-#### dm.mountopt
-
-Specifies extra mount options used when mounting the thin devices.
-
-Example use: `dockerd --storage-opt dm.mountopt=nodiscard`
-
-#### dm.use_deferred_removal
-
-Enables use of deferred device removal if `libdm` and the kernel driver
-support the mechanism.
-
-Deferred device removal means that if device is busy when devices are
-being removed/deactivated, then a deferred removal is scheduled on
-device. And devices automatically go away when last user of the device
-exits.
-
-For example, when a container exits, its associated thin device is removed. If
-that device has leaked into some other mount namespace and can't be removed,
-the container exit still succeeds and this option causes the system to schedule
-the device for deferred removal. It does not wait in a loop trying to remove a
-busy device.
-
-Example use: `dockerd --storage-opt dm.use_deferred_removal=true`
-
-#### dm.use_deferred_deletion
-
-Enables use of deferred device deletion for thin pool devices. By default,
-thin pool device deletion is synchronous. Before a container is deleted, the
-Docker daemon removes any associated devices. If the storage driver can not
-remove a device, the container deletion fails and daemon returns.
-
-`Error deleting container: Error response from daemon: Cannot destroy container`
-
-To avoid this failure, enable both deferred device deletion and deferred
-device removal on the daemon.
-
-`dockerd --storage-opt dm.use_deferred_deletion=true --storage-opt dm.use_deferred_removal=true`
-
-With these two options enabled, if a device is busy when the driver is
-deleting a container, the driver marks the device as deleted. Later, when the
-device isn't in use, the driver deletes it.
-
-In general it should be safe to enable this option by default. It will help
-when unintentional leaking of mount point happens across multiple mount
-namespaces.
-
-#### dm.loopdatasize
-
-**Note**: This option configures devicemapper loopback, which should not be
-used in production.
-
-Specifies the size to use when creating the loopback file for the "data" device
-which is used for the thin pool. The default size is 100G. The file is sparse,
-so it will not initially take up this much space.
-
-Example use: `dockerd --storage-opt dm.loopdatasize=200G`
-
-#### dm.loopmetadatasize
-
-**Note**: This option configures devicemapper loopback, which should not be
-used in production.
-
-Specifies the size to use when creating the loopback file for the "metadata"
-device which is used for the thin pool. The default size is 2G. The file is
-sparse, so it will not initially take up this much space.
-
-Example use: `dockerd --storage-opt dm.loopmetadatasize=4G`
-
-#### dm.datadev
-
-(Deprecated, use `dm.thinpooldev`)
-
-Specifies a custom blockdevice to use for data for a Docker-managed thin pool.
-It is better to use `dm.thinpooldev` - see the documentation for it above for
-discussion of the advantages.
-
-#### dm.metadatadev
-
-(Deprecated, use `dm.thinpooldev`)
-
-Specifies a custom blockdevice to use for metadata for a Docker-managed thin
-pool.  See `dm.datadev` for why this is deprecated.
-
-#### dm.blocksize
-
-Specifies a custom blocksize to use for the thin pool.  The default
-blocksize is 64K.
-
-Example use: `dockerd --storage-opt dm.blocksize=512K`
-
-#### dm.blkdiscard
-
-Enables or disables the use of `blkdiscard` when removing devicemapper devices.
-This is disabled by default due to the additional latency, but as a special
-case with loopback devices it will be enabled, in order to re-sparsify the
-loopback file on image/container removal.
-
-Disabling this on loopback can lead to *much* faster container removal times,
-but it also prevents the space used in `/var/lib/docker` directory from being
-returned to the system for other use when containers are removed.
-
-Example use: `dockerd --storage-opt dm.blkdiscard=false`
-
-#### dm.override_udev_sync_check
-
-By default, the devicemapper backend attempts to synchronize with the `udev`
-device manager for the Linux kernel.  This option allows disabling that
-synchronization, to continue even though the configuration may be buggy.
-
-To view the `udev` sync support of a Docker daemon that is using the
-`devicemapper` driver, run:
-
-        $ docker info
-        [...]
-         Udev Sync Supported: true
-        [...]
-
-When `udev` sync support is `true`, then `devicemapper` and `udev` can
-coordinate the activation and deactivation of devices for containers.
-
-When `udev` sync support is `false`, a race condition occurs between the
-`devicemapper` and `udev` during create and cleanup. The race condition results
-in errors and failures. (For information on these failures, see
-[docker#4036](https://github.com/docker/docker/issues/4036))
-
-To allow the `docker` daemon to start, regardless of whether `udev` sync is
-`false`, set `dm.override_udev_sync_check` to true:
-
-        $ dockerd --storage-opt dm.override_udev_sync_check=true
-
-When this value is `true`, the driver continues and simply warns you the errors
-are happening.
-
-**Note**: The ideal is to pursue a `docker` daemon and environment that does
-support synchronizing with `udev`. For further discussion on this topic, see
-[docker#4036](https://github.com/docker/docker/issues/4036).
-Otherwise, set this flag for migrating existing Docker daemons to a daemon with
-a supported environment.
-
-#### dm.min_free_space
-
-Specifies the min free space percent in a thin pool require for new device
-creation to succeed. This check applies to both free data space as well
-as free metadata space. Valid values are from 0% - 99%. Value 0% disables
-free space checking logic. If user does not specify a value for this option,
-the Engine uses a default value of 10%.
-
-Whenever a new a thin pool device is created (during `docker pull` or during
-container creation), the Engine checks if the minimum free space is available.
-If the space is unavailable, then device creation fails and any relevant
-`docker` operation fails.
-
-To recover from this error, you must create more free space in the thin pool to
-recover from the error. You can create free space by deleting some images and
-containers from tge thin pool. You can also add more storage to the thin pool.
-
-To add more space to an LVM (logical volume management) thin pool, just add
-more storage to the  group container thin pool; this should automatically
-resolve any errors. If your configuration uses loop devices, then stop the
-Engine daemon, grow the size of loop files and restart the daemon to resolve
-the issue.
-
-Example use:: `dockerd --storage-opt dm.min_free_space=10%`
-
-#### dm.xfs_nospace_max_retries
-
-Specifies the maximum number of retries XFS should attempt to complete IO when
-ENOSPC (no space) error is returned by underlying storage device.
-
-By default XFS retries infinitely for IO to finish and this can result in
-unkillable process. To change this behavior one can set xfs_nospace_max_retries
-to say 0 and XFS will not retry IO after getting ENOSPC and will shutdown
-filesystem.
-
-Example use:
-
-    $ sudo dockerd --storage-opt dm.xfs_nospace_max_retries=0
-
-
-## ZFS options
-
-#### zfs.fsname
-
-Set zfs filesystem under which docker will create its own datasets.  By default
-docker will pick up the zfs filesystem where docker graph (`/var/lib/docker`)
-is located.
-
-Example use: `dockerd -s zfs --storage-opt zfs.fsname=zroot/docker`
-
-## Btrfs options
-
-#### btrfs.min_space
-
-Specifies the minimum size to use when creating the subvolume which is used for
-containers. If user uses disk quota for btrfs when creating or running a
-container with **--storage-opt size** option, docker should ensure the **size**
-cannot be smaller than **btrfs.min_space**.
-
-Example use: `docker daemon -s btrfs --storage-opt btrfs.min_space=10G`
-
-# CLUSTER STORE OPTIONS
-
-The daemon uses libkv to advertise the node within the cluster.  Some Key/Value
-backends support mutual TLS, and the client TLS settings used by the daemon can
-be configured using the **--cluster-store-opt** flag, specifying the paths to
-PEM encoded files.
-
-#### kv.cacertfile
-
-Specifies the path to a local file with PEM encoded CA certificates to trust
-
-#### kv.certfile
-
-Specifies the path to a local file with a PEM encoded certificate.  This
-certificate is used as the client cert for communication with the Key/Value
-store.
-
-#### kv.keyfile
-
-Specifies the path to a local file with a PEM encoded private key.  This
-private key is used as the client key for communication with the Key/Value
-store.
-
-# Access authorization
-
-Docker's access authorization can be extended by authorization plugins that
-your organization can purchase or build themselves. You can install one or more
-authorization plugins when you start the Docker `daemon` using the
-`--authorization-plugin=PLUGIN_ID` option.
-
-```bash
-dockerd --authorization-plugin=plugin1 --authorization-plugin=plugin2,...
-```
-
-The `PLUGIN_ID` value is either the plugin's name or a path to its
-specification file. The plugin's implementation determines whether you can
-specify a name or path. Consult with your Docker administrator to get
-information about the plugins available to you.
-
-Once a plugin is installed, requests made to the `daemon` through the
-command line or Docker's Engine API are allowed or denied by the plugin.
-If you have multiple plugins installed, each plugin, in order, must
-allow the request for it to complete.
-
-For information about how to create an authorization plugin, see [authorization
-plugin](https://docs.docker.com/engine/extend/authorization/) section in the
-Docker extend section of this documentation.
-
-# RUNTIME EXECUTION OPTIONS
-
-You can configure the runtime using options specified with the `--exec-opt` flag.
-All the flag's options have the `native` prefix. A single `native.cgroupdriver`
-option is available.
-
-The `native.cgroupdriver` option specifies the management of the container's
-cgroups. You can only specify `cgroupfs` or `systemd`. If you specify
-`systemd` and it is not available, the system errors out. If you omit the
-`native.cgroupdriver` option,` cgroupfs` is used.
-
-This example sets the `cgroupdriver` to `systemd`:
-
-```bash
-$ sudo dockerd --exec-opt native.cgroupdriver=systemd
-```
-
-Setting this option applies to all containers the daemon launches.

-The **docker attach** command allows you to attach to a running container using
-the container's ID or name, either to view its ongoing output or to control it
-interactively.  You can attach to the same contained process multiple times
-simultaneously, screen sharing style, or quickly view the progress of your
-detached process.
-
-To stop a container, use `CTRL-c`. This key sequence sends `SIGKILL` to the
-container. You can detach from the container (and leave it running) using a
-configurable key sequence. The default sequence is `CTRL-p CTRL-q`. You
-configure the key sequence using the **--detach-keys** option or a configuration
-file. See **config-json(5)** for documentation on using a configuration file.
-
-It is forbidden to redirect the standard input of a `docker attach` command while
-attaching to a tty-enabled container (i.e.: launched with `-t`).
-
-# Override the detach sequence
-
-If you want, you can configure an override the Docker key sequence for detach.
-This is useful if the Docker default sequence conflicts with key sequence you
-use for other applications. There are two ways to define your own detach key
-sequence, as a per-container override or as a configuration property on  your
-entire configuration.
-
-To override the sequence for an individual container, use the
-`--detach-keys="<sequence>"` flag with the `docker attach` command. The format of
-the `<sequence>` is either a letter [a-Z], or the `ctrl-` combined with any of
-the following:
-
-* `a-z` (a single lowercase alpha character )
-* `@` (at sign)
-* `[` (left bracket)
-* `\\` (two backward slashes)
-*  `_` (underscore)

-Create a new image from an existing container specified by name or
-container ID.  The new image will contain the contents of the
-container filesystem, *excluding* any data volumes. Refer to **docker-tag(1)**
-for more information about valid image and tag names.
-
-While the `docker commit` command is a convenient way of extending an
-existing image, you should prefer the use of a Dockerfile and `docker
-build` for generating images that you intend to share with other
-people.
-
-# EXAMPLES
-
-## Creating a new image from an existing container
-An existing Fedora based container has had Apache installed while running
-in interactive mode with the bash shell. Apache is also running. To
-create a new image run `docker ps` to find the container's ID and then run:
-
-    $ docker commit -m="Added Apache to Fedora base image" \
-      -a="A D Ministrator" 98bd7fc99854 fedora/fedora_httpd:20
-
-Note that only a-z0-9-_. are allowed when naming images from an 
-existing container.
-
-## Apply specified Dockerfile instructions while committing the image
-If an existing container was created without the DEBUG environment
-variable set to "true", you can create a new image based on that
-container by first getting the container's ID with `docker ps` and
-then running:
-
-    $ docker container commit -c="ENV DEBUG true" 98bd7fc99854 debug-image

-The `docker container cp` utility copies the contents of `SRC_PATH` to the `DEST_PATH`.
-You can copy from the container's file system to the local machine or the
-reverse, from the local filesystem to the container. If `-` is specified for
-either the `SRC_PATH` or `DEST_PATH`, you can also stream a tar archive from
-`STDIN` or to `STDOUT`. The `CONTAINER` can be a running or stopped container.
-The `SRC_PATH` or `DEST_PATH` can be a file or directory.
-
-The `docker container cp` command assumes container paths are relative to the container's 
-`/` (root) directory. This means supplying the initial forward slash is optional; 
-The command sees `compassionate_darwin:/tmp/foo/myfile.txt` and
-`compassionate_darwin:tmp/foo/myfile.txt` as identical. Local machine paths can
-be an absolute or relative value. The command interprets a local machine's
-relative paths as relative to the current working directory where `docker container cp` is
-run.
-
-The `cp` command behaves like the Unix `cp -a` command in that directories are
-copied recursively with permissions preserved if possible. Ownership is set to
-the user and primary group at the destination. For example, files copied to a
-container are created with `UID:GID` of the root user. Files copied to the local
-machine are created with the `UID:GID` of the user which invoked the `docker container cp`
-command.  If you specify the `-L` option, `docker container cp` follows any symbolic link
-in the `SRC_PATH`. `docker container cp` does *not* create parent directories for
-`DEST_PATH` if they do not exist.
-
-Assuming a path separator of `/`, a first argument of `SRC_PATH` and second
-argument of `DEST_PATH`, the behavior is as follows:
-
-- `SRC_PATH` specifies a file
-    - `DEST_PATH` does not exist
-        - the file is saved to a file created at `DEST_PATH`
-    - `DEST_PATH` does not exist and ends with `/`
-        - Error condition: the destination directory must exist.
-    - `DEST_PATH` exists and is a file
-        - the destination is overwritten with the source file's contents
-    - `DEST_PATH` exists and is a directory
-        - the file is copied into this directory using the basename from
-          `SRC_PATH`
-- `SRC_PATH` specifies a directory
-    - `DEST_PATH` does not exist
-        - `DEST_PATH` is created as a directory and the *contents* of the source
-           directory are copied into this directory
-    - `DEST_PATH` exists and is a file
-        - Error condition: cannot copy a directory to a file
-    - `DEST_PATH` exists and is a directory
-        - `SRC_PATH` does not end with `/.` (that is: _slash_ followed by _dot_)
-            - the source directory is copied into this directory
-        - `SRC_PATH` does end with `/.` (that is: _slash_ followed by _dot_)
-            - the *content* of the source directory is copied into this
-              directory
-
-The command requires `SRC_PATH` and `DEST_PATH` to exist according to the above
-rules. If `SRC_PATH` is local and is a symbolic link, the symbolic link, not
-the target, is copied by default. To copy the link target and not the link, 
-specify the `-L` option.
-
-A colon (`:`) is used as a delimiter between `CONTAINER` and its path. You can
-also use `:` when specifying paths to a `SRC_PATH` or `DEST_PATH` on a local
-machine, for example  `file:name.txt`. If you use a `:` in a local machine path,
-you must be explicit with a relative or absolute path, for example:
-
-    `/path/to/file:name.txt` or `./file:name.txt`
-
-It is not possible to copy certain system files such as resources under
-`/proc`, `/sys`, `/dev`, tmpfs, and mounts created by the user in the container.
-However, you can still copy such files by manually running `tar` in `docker exec`.
-For example (consider `SRC_PATH` and `DEST_PATH` are directories):
-
-    $ docker exec foo tar Ccf $(dirname SRC_PATH) - $(basename SRC_PATH) | tar Cxf DEST_PATH -
-
-or
-
-    $ tar Ccf $(dirname SRC_PATH) - $(basename SRC_PATH) | docker exec -i foo tar Cxf DEST_PATH -
-
-
-Using `-` as the `SRC_PATH` streams the contents of `STDIN` as a tar archive.
-The command extracts the content of the tar to the `DEST_PATH` in container's
-filesystem. In this case, `DEST_PATH` must specify a directory. Using `-` as
-the `DEST_PATH` streams the contents of the resource as a tar archive to `STDOUT`.
-
-# EXAMPLES
-
-Suppose a container has finished producing some output as a file it saves
-to somewhere in its filesystem. This could be the output of a build job or
-some other computation. You can copy these outputs from the container to a
-location on your local host.
-
-If you want to copy the `/tmp/foo` directory from a container to the
-existing `/tmp` directory on your host. If you run `docker container cp` in your `~`
-(home) directory on the local host:
-
-    $ docker container cp compassionate_darwin:tmp/foo /tmp
-
-Docker creates a `/tmp/foo` directory on your host. Alternatively, you can omit
-the leading slash in the command. If you execute this command from your home
-directory:
-
-    $ docker container cp compassionate_darwin:tmp/foo tmp
-
-If `~/tmp` does not exist, Docker will create it and copy the contents of
-`/tmp/foo` from the container into this new directory. If `~/tmp` already
-exists as a directory, then Docker will copy the contents of `/tmp/foo` from
-the container into a directory at `~/tmp/foo`.
-
-When copying a single file to an existing `LOCALPATH`, the `docker container cp` command
-will either overwrite the contents of `LOCALPATH` if it is a file or place it
-into `LOCALPATH` if it is a directory, overwriting an existing file of the same
-name if one exists. For example, this command:
-
-    $ docker container cp sharp_ptolemy:/tmp/foo/myfile.txt /test
-
-If `/test` does not exist on the local machine, it will be created as a file
-with the contents of `/tmp/foo/myfile.txt` from the container. If `/test`
-exists as a file, it will be overwritten. Lastly, if `/test` exists as a
-directory, the file will be copied to `/test/myfile.txt`.
-
-Next, suppose you want to copy a file or folder into a container. For example,
-this could be a configuration file or some other input to a long running
-computation that you would like to place into a created container before it
-starts. This is useful because it does not require the configuration file or
-other input to exist in the container image.
-
-If you have a file, `config.yml`, in the current directory on your local host
-and wish to copy it to an existing directory at `/etc/my-app.d` in a container,
-this command can be used:
-
-    $ docker container cp config.yml myappcontainer:/etc/my-app.d
-
-If you have several files in a local directory `/config` which you need to copy
-to a directory `/etc/my-app.d` in a container:
-
-    $ docker container cp /config/. myappcontainer:/etc/my-app.d
-
-The above command will copy the contents of the local `/config` directory into
-the directory `/etc/my-app.d` in the container.
-
-Finally, if you want to copy a symbolic link into a container, you typically
-want to  copy the linked target and not the link itself. To copy the target, use
-the `-L` option, for example:
-
-    $ ln -s /tmp/somefile /tmp/somefile.ln
-    $ docker container cp -L /tmp/somefile.ln myappcontainer:/tmp/
-
-This command copies content of the local `/tmp/somefile` into the file
-`/tmp/somefile.ln` in the container. Without `-L` option, the `/tmp/somefile.ln`
-preserves its symbolic link but not its content.

-### Specify isolation technology for container (--isolation)
-
-This option is useful in situations where you are running Docker containers on
-Windows. The `--isolation=<value>` option sets a container's isolation
-technology. On Linux, the only supported is the `default` option which uses
-Linux namespaces. On Microsoft Windows, you can specify these values:
-
-* `default`: Use the value specified by the Docker daemon's `--exec-opt` . If the `daemon` does not specify an isolation technology, Microsoft Windows uses `process` as its default value.
-* `process`: Namespace isolation only.
-* `hyperv`: Hyper-V hypervisor partition-based isolation.
-
-Specifying the `--isolation` flag without a value is the same as setting `--isolation="default"`.
-
-### Dealing with dynamically created devices (--device-cgroup-rule)
-
-Devices available to a container are assigned at creation time. The
-assigned devices will both be added to the cgroup.allow file and
-created into the container once it is run. This poses a problem when
-a new device needs to be added to running container.
-
-One of the solution is to add a more permissive rule to a container
-allowing it access to a wider range of devices. For example, supposing
-our container needs access to a character device with major `42` and
-any number of minor number (added as new devices appear), the
-following rule would be added:
-
-```
-docker create --device-cgroup-rule='c 42:* rmw' -name my-container my-image
-```
-
-Then, a user could ask `udev` to execute a script that would `docker exec my-container mknod newDevX c 42 <minor>`
-the required device when it is added.
-
-NOTE: initially present devices still need to be explicitly added to
-the create/run command

-Creates a writeable container layer over the specified image and prepares it for
-running the specified command. The container ID is then printed to STDOUT. This
-is similar to **docker run -d** except the container is never started. You can 
-then use the **docker start <container_id>** command to start the container at
-any point.
-
-The initial status of the container created with **docker create** is 'created'.
-
-### OPTIONS 
-
-The `CONTAINER-DIR` must be an absolute path such as `/src/docs`. The `HOST-DIR`
-can be an absolute path or a `name` value. A `name` value must start with an
-alphanumeric character, followed by `a-z0-9`, `_` (underscore), `.` (period) or
-`-` (hyphen). An absolute path starts with a `/` (forward slash).
-
-If you supply a `HOST-DIR` that is an absolute path,  Docker bind-mounts to the
-path you specify. If you supply a `name`, Docker creates a named volume by that
-`name`. For example, you can specify either `/foo` or `foo` for a `HOST-DIR`
-value. If you supply the `/foo` value, Docker creates a bind-mount. If you
-supply the `foo` specification, Docker creates a named volume.
-
-You can specify multiple  **-v** options to mount one or more mounts to a
-container. To use these same mounts in other containers, specify the
-**--volumes-from** option also.
-
-You can supply additional options for each bind-mount following an additional
-colon.  A `:ro` or `:rw` suffix mounts a volume in read-only or read-write
-mode, respectively. By default, volumes are mounted in read-write mode.  
-You can also specify the consistency requirement for the mount, either
-`:consistent` (the default), `:cached`, or `:delegated`.  Multiple options are
-separated by commas, e.g. `:ro,cached`.
-
-Labeling systems like SELinux require that proper labels are placed on volume
-content mounted into a container. Without a label, the security system might
-prevent the processes running inside the container from using the content. By
-default, Docker does not change the labels set by the OS.
-
-To change a label in the container context, you can add either of two suffixes
-`:z` or `:Z` to the volume mount. These suffixes tell Docker to relabel file
-objects on the shared volumes. The `z` option tells Docker that two containers
-share the volume content. As a result, Docker labels the content with a shared
-content label. Shared volume labels allow all containers to read/write content.
-The `Z` option tells Docker to label the content with a private unshared label.
-Only the current container can use a private volume.
-
-By default bind mounted volumes are `private`. That means any mounts done
-inside container will not be visible on host and vice-a-versa. One can change
-this behavior by specifying a volume mount propagation property. Making a
-volume `shared` mounts done under that volume inside container will be
-visible on host and vice-a-versa. Making a volume `slave` enables only one
-way mount propagation and that is mounts done on host under that volume
-will be visible inside container but not the other way around.
-
-To control mount propagation property of volume one can use `:[r]shared`,
-`:[r]slave` or `:[r]private` propagation flag. Propagation property can
-be specified only for bind mounted volumes and not for internal volumes or
-named volumes. For mount propagation to work source mount point (mount point
-where source dir is mounted on) has to have right propagation properties. For
-shared volumes, source mount point has to be shared. And for slave volumes,
-source mount has to be either shared or slave.
-
-Use `df <source-dir>` to figure out the source mount and then use
-`findmnt -o TARGET,PROPAGATION <source-mount-dir>` to figure out propagation
-properties of source mount. If `findmnt` utility is not available, then one
-can look at mount entry for source mount point in `/proc/self/mountinfo`. Look
-at `optional fields` and see if any propagation properties are specified.
-`shared:X` means mount is `shared`, `master:X` means mount is `slave` and if
-nothing is there that means mount is `private`.
-
-To change propagation properties of a mount point use `mount` command. For
-example, if one wants to bind mount source directory `/foo` one can do
-`mount --bind /foo /foo` and `mount --make-private --make-shared /foo`. This
-will convert /foo into a `shared` mount point. Alternatively one can directly
-change propagation properties of source mount. Say `/` is source mount for
-`/foo`, then use `mount --make-shared /` to convert `/` into a `shared` mount.
-
-> **Note**:
-> When using systemd to manage the Docker daemon's start and stop, in the systemd
-> unit file there is an option to control mount propagation for the Docker daemon
-> itself, called `MountFlags`. The value of this setting may cause Docker to not
-> see mount propagation changes made on the mount point. For example, if this value
-> is `slave`, you may not be able to use the `shared` or `rshared` propagation on
-> a volume.
-
-
-To disable automatic copying of data from the container path to the volume, use
-the `nocopy` flag. The `nocopy` flag can be set on bind mounts and named volumes.

-The **docker container update** command dynamically updates container configuration.
-You can use this command to prevent containers from consuming too many 
-resources from their Docker host.  With a single command, you can place 
-limits on a single container or on many. To specify more than one container,
-provide space-separated list of container names or IDs.
-
-With the exception of the **--kernel-memory** option, you can specify these
-options on a running or a stopped container. On kernel version older than
-4.6, You can only update **--kernel-memory** on a stopped container or on
-a running container with kernel memory initialized.
-
-# OPTIONS
-
-## kernel-memory
-
-Kernel memory limit (format: `<number>[<unit>]`, where unit = b, k, m or g)
-
-Note that on kernel version older than 4.6, you can not update kernel memory on
-a running container if the container is started without kernel memory initialized,
-in this case, it can only be updated after it's stopped. The new setting takes
-effect when the container is started.
-
-## memory
-
-Memory limit (format: <number><optional unit>, where unit = b, k, m or g)
-
-Note that the memory should be smaller than the already set swap memory limit.
-If you want update a memory limit bigger than the already set swap memory limit,
-you should update swap memory limit at the same time. If you don't set swap memory 
-limit on docker create/run but only memory limit, the swap memory is double
-the memory limit.
-
-# EXAMPLES
-
-The following sections illustrate ways to use this command.
-
-### Update a container's cpu-shares
-
-To limit a container's cpu-shares to 512, first identify the container
-name or ID. You can use **docker ps** to find these values. You can also
-use the ID returned from the **docker run** command.  Then, do the following:
-
-```bash
-$ docker container update --cpu-shares 512 abebf7571666
-```
-
-### Update a container with cpu-shares and memory
-
-To update multiple resource configurations for multiple containers:
-
-```bash
-$ docker container update --cpu-shares 512 -m 300M abebf7571666 hopeful_morse
-```
-
-### Update a container's kernel memory constraints
-
-You can update a container's kernel memory limit using the **--kernel-memory**
-option. On kernel version older than 4.6, this option can be updated on a
-running container only if the container was started with **--kernel-memory**.
-If the container was started *without* **--kernel-memory** you need to stop
-the container before updating kernel memory.
-
-For example, if you started a container with this command:
-
-```bash
-$ docker run -dit --name test --kernel-memory 50M ubuntu bash
-```
-
-You can update kernel memory while the container is running:
-
-```bash
-$ docker container update --kernel-memory 80M test
-```
-
-If you started a container *without* kernel memory initialized:
-
-```bash
-$ docker run -dit --name test2 --memory 300M ubuntu bash
-```
-
-Update kernel memory of running container `test2` will fail. You need to stop
-the container before updating the **--kernel-memory** setting. The next time you
-start it, the container uses the new value.
-
-Kernel version newer than (include) 4.6 does not have this limitation, you
-can use `--kernel-memory` the same way as other options.
-
-### Update a container's restart policy
-
-You can change a container's restart policy on a running container. The new
-restart policy takes effect instantly after you run `docker container update` on a
-container.
-
-To update restart policy for one or more containers:
-
-```bash
-$ docker container update --restart=on-failure:3 abebf7571666 hopeful_morse
-```
-
-Note that if the container is started with "--rm" flag, you cannot update the restart
-policy for it. The `AutoRemove` and `RestartPolicy` are mutually exclusive for the
-container.

-### Format the output
-
-The formatting option (`--format`) will pretty-prints history output
-using a Go template.
-
-Valid placeholders for the Go template are listed below:
-
-| Placeholder     | Description |
-| --------------- | ----------- |
-| `.ID`           | Image ID    |
-| `.CreatedSince` | Elapsed time since the image was created if `--human=true`, otherwise timestamp of when image was created |
-| `.CreatedAt`    | Timestamp of when image was created |
-| `.CreatedBy`    | Command that was used to create the image |
-| `.Size`         | Image disk size |
-| `.Comment`      | Comment for image |
-
-When using the `--format` option, the `history` command will either
-output the data exactly as the template declares or, when using the
-`table` directive, will include column headers as well.
-
-The following example uses a template without headers and outputs the
-`ID` and `CreatedSince` entries separated by a colon for all images:
-
-```bash
-$ docker images --format "{{.ID}}: {{.Created}} ago"

-This command lists the images stored in the local Docker repository.
-
-By default, intermediate images, used during builds, are not listed. Some of the
-output, e.g., image ID, is truncated, for space reasons. However the truncated
-image ID, and often the first few characters, are enough to be used in other
-Docker commands that use the image ID. The output includes repository, tag, image
-ID, date created and the virtual size.
-
-The title REPOSITORY for the first title may seem confusing. It is essentially
-the image name. However, because you can tag a specific image, and multiple tags
-(image instances) can be associated with a single name, the name is really a
-repository for all tagged images of the same name. For example consider an image
-called fedora. It may be tagged with 18, 19, or 20, etc. to manage different
-versions.
-
-## Filters
-
-Filters the output based on these conditions:
-
-   - dangling=(true|false) - find unused images
-   - label=<key> or label=<key>=<value>
-   - before=(<image-name>[:tag]|<image-id>|<image@digest>)
-   - since=(<image-name>[:tag]|<image-id>|<image@digest>)
-   - reference=(pattern of an image reference)
-
-## Format
-
-   Pretty-print images using a Go template.
-   Valid placeholders:
-      .ID - Image ID
-      .Repository - Image repository
-      .Tag - Image tag
-      .Digest - Image digest
-      .CreatedSince - Elapsed time since the image was created
-      .CreatedAt - Time when the image was created
-      .Size - Image disk size
-
-# EXAMPLES
-
-## Listing the images
-
-To list the images in a local repository (not the registry) run:
-
-    docker image ls
-
-The list will contain the image repository name, a tag for the image, and an
-image ID, when it was created and its virtual size. Columns: REPOSITORY, TAG,
-IMAGE ID, CREATED, and SIZE.
-
-The `docker image ls` command takes an optional `[REPOSITORY[:TAG]]` argument
-that restricts the list to images that match the argument. If you specify
-`REPOSITORY` but no `TAG`, the `docker image ls` command lists all images in the
-given repository.
-
-    docker image ls java
-
-The `[REPOSITORY[:TAG]]` value must be an "exact match". This means that, for example,
-`docker image ls jav` does not match the image `java`.
-
-If both `REPOSITORY` and `TAG` are provided, only images matching that
-repository and tag are listed.  To find all local images in the "java"
-repository with tag "8" you can use:
-
-    docker image ls java:8
-
-To get a verbose list of images which contains all the intermediate images
-used in builds use **-a**:
-
-    docker image ls -a
-
-Previously, the docker image ls command supported the --tree and --dot arguments,
-which displayed different visualizations of the image data. Docker core removed
-this functionality in the 1.7 version. If you liked this functionality, you can
-still find it in the third-party dockviz tool: https://github.com/justone/dockviz.
-
-## Listing images in a desired format
-
-When using the --format option, the image command will either output the data 
-exactly as the template declares or, when using the `table` directive, will 
-include column headers as well. You can use special characters like `\t` for
-inserting tab spacing between columns. 
-
-The following example uses a template without headers and outputs the ID and 
-Repository entries separated by a colon for all images:
-
-    docker images --format "{{.ID}}: {{.Repository}}"
-    77af4d6b9913: <none>
-    b6fa739cedf5: committ

-    746b819f315e: postgres
-
-To list all images with their repository and tag in a table format you can use:
-
-    docker images --format "table {{.ID}}\t{{.Repository}}\t{{.Tag}}"
-    IMAGE ID            REPOSITORY                TAG

-
-# EXAMPLES
-
-### Pull an image from Docker Hub
-
-To download a particular image, or set of images (i.e., a repository), use
-`docker image pull`. If no tag is provided, Docker Engine uses the `:latest` tag as a
-default. This command pulls the `debian:latest` image:
-
-    $ docker image pull debian
-
-    Using default tag: latest
-    latest: Pulling from library/debian
-    fdd5d7827f33: Pull complete
-    a3ed95caeb02: Pull complete
-    Digest: sha256:e7d38b3517548a1c71e41bffe9c8ae6d6d29546ce46bf62159837aad072c90aa
-    Status: Downloaded newer image for debian:latest
-
-Docker images can consist of multiple layers. In the example above, the image
-consists of two layers; `fdd5d7827f33` and `a3ed95caeb02`.
-
-Layers can be reused by images. For example, the `debian:jessie` image shares
-both layers with `debian:latest`. Pulling the `debian:jessie` image therefore
-only pulls its metadata, but not its layers, because all layers are already
-present locally:
-
-    $ docker image pull debian:jessie
-
-    jessie: Pulling from library/debian
-    fdd5d7827f33: Already exists
-    a3ed95caeb02: Already exists
-    Digest: sha256:a9c958be96d7d40df920e7041608f2f017af81800ca5ad23e327bc402626b58e
-    Status: Downloaded newer image for debian:jessie
-
-To see which images are present locally, use the **docker-images(1)**
-command:
-
-    $ docker images
-
-    REPOSITORY   TAG      IMAGE ID        CREATED      SIZE
-    debian       jessie   f50f9524513f    5 days ago   125.1 MB
-    debian       latest   f50f9524513f    5 days ago   125.1 MB
-
-Docker uses a content-addressable image store, and the image ID is a SHA256
-digest covering the image's configuration and layers. In the example above,
-`debian:jessie` and `debian:latest` have the same image ID because they are
-actually the *same* image tagged with different names. Because they are the
-same image, their layers are stored only once and do not consume extra disk
-space.
-
-For more information about images, layers, and the content-addressable store,
-refer to [understand images, containers, and storage drivers](https://docs.docker.com/engine/userguide/storagedriver/imagesandcontainers/)
-in the online documentation.
-
-
-## Pull an image by digest (immutable identifier)
-
-So far, you've pulled images by their name (and "tag"). Using names and tags is
-a convenient way to work with images. When using tags, you can `docker image pull` an
-image again to make sure you have the most up-to-date version of that image.
-For example, `docker image pull ubuntu:14.04` pulls the latest version of the Ubuntu
-14.04 image.
-
-In some cases you don't want images to be updated to newer versions, but prefer
-to use a fixed version of an image. Docker enables you to pull an image by its
-*digest*. When pulling an image by digest, you specify *exactly* which version
-of an image to pull. Doing so, allows you to "pin" an image to that version,
-and guarantee that the image you're using is always the same.
-
-To know the digest of an image, pull the image first. Let's pull the latest
-`ubuntu:14.04` image from Docker Hub:
-
-    $ docker image pull ubuntu:14.04
-
-    14.04: Pulling from library/ubuntu
-    5a132a7e7af1: Pull complete
-    fd2731e4c50c: Pull complete
-    28a2f68d1120: Pull complete
-    a3ed95caeb02: Pull complete
-    Digest: sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2
-    Status: Downloaded newer image for ubuntu:14.04
-
-Docker prints the digest of the image after the pull has finished. In the example
-above, the digest of the image is:
-
-    sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2
-
-Docker also prints the digest of an image when *pushing* to a registry. This
-may be useful if you want to pin to a version of the image you just pushed.
-
-A digest takes the place of the tag when pulling an image, for example, to 
-pull the above image by digest, run the following command:
-
-    $ docker image pull ubuntu@sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2
-
-    sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2: Pulling from library/ubuntu
-    5a132a7e7af1: Already exists
-    fd2731e4c50c: Already exists
-    28a2f68d1120: Already exists
-    a3ed95caeb02: Already exists
-    Digest: sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2
-    Status: Downloaded newer image for ubuntu@sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2
-
-Digest can also be used in the `FROM` of a Dockerfile, for example:
-
-    FROM ubuntu@sha256:45b23dee08af5e43a7fea6c4cf9c25ccf269ee113168c19722f87876677c5cb2
-    MAINTAINER some maintainer <maintainer@example.com>
-
-> **Note**: Using this feature "pins" an image to a specific version in time.
-> Docker will therefore not pull updated versions of an image, which may include 
-> security updates. If you want to pull an updated image, you need to change the
-> digest accordingly.
-
-## Pulling from a different registry
-
-By default, `docker image pull` pulls images from Docker Hub. It is also possible to
-manually specify the path of a registry to pull from. For example, if you have
-set up a local registry, you can specify its path to pull from it. A registry
-path is similar to a URL, but does not contain a protocol specifier (`https://`).
-
-The following command pulls the `testing/test-image` image from a local registry
-listening on port 5000 (`myregistry.local:5000`):
-
-    $ docker image pull myregistry.local:5000/testing/test-image
-
-Registry credentials are managed by **docker-login(1)**.
-
-Docker uses the `https://` protocol to communicate with a registry, unless the
-registry is allowed to be accessed over an insecure connection. Refer to the
-[insecure registries](https://docs.docker.com/engine/reference/commandline/daemon/#insecure-registries)
-section in the online documentation for more information.

-## Pull a repository with multiple images
-
-By default, `docker image pull` pulls a *single* image from the registry. A repository
-can contain multiple images. To pull all images from a repository, provide the
-`-a` (or `--all-tags`) option when using `docker image pull`.
-
-This command pulls all images from the `fedora` repository:
-
-    $ docker image pull --all-tags fedora
-
-    Pulling repository fedora
-    ad57ef8d78d7: Download complete
-    105182bb5e8b: Download complete
-    511136ea3c5a: Download complete
-    73bd853d2ea5: Download complete
-    ....
-
-    Status: Downloaded newer image for fedora
-
-After the pull has completed use the `docker images` command to see the
-images that were pulled. The example below shows all the `fedora` images
-that are present locally:
-
-    $ docker images fedora
-
-    REPOSITORY   TAG         IMAGE ID        CREATED      SIZE
-    fedora       rawhide     ad57ef8d78d7    5 days ago   359.3 MB
-    fedora       20          105182bb5e8b    5 days ago   372.7 MB
-    fedora       heisenbug   105182bb5e8b    5 days ago   372.7 MB
-    fedora       latest      105182bb5e8b    5 days ago   372.7 MB
-
-
-## Canceling a pull
-
-Killing the `docker image pull` process, for example by pressing `CTRL-c` while it is
-running in a terminal, will terminate the pull operation.
-
-    $ docker image pull fedora
-
-    Using default tag: latest
-    latest: Pulling from library/fedora
-    a3ed95caeb02: Pulling fs layer
-    236608c7b546: Pulling fs layer
-    ^C
-
-> **Note**: Technically, the Engine terminates a pull operation when the
-> connection between the Docker Engine daemon and the Docker Engine client
-> initiating the pull is lost. If the connection with the Engine daemon is
-> lost for other reasons than a manual interaction, the pull is also aborted.

-Use `docker image push` to share your images to the [Docker Hub](https://hub.docker.com)

-
-# EXAMPLES
-
-## Pushing a new image to a registry
-
-First save the new image by finding the container ID (using **docker container ls**)
-and then committing it to a new image name.  Note that only a-z0-9-_. are
-allowed when naming images:
-
-    # docker container commit c16378f943fe rhel-httpd
-
-Now, push the image to the registry using the image ID. In this example the
-registry is on host named `registry-host` and listening on port `5000`. To do
-this, tag the image with the host name or IP address, and the port of the
-registry:
-
-    # docker image tag rhel-httpd registry-host:5000/myadmin/rhel-httpd
-    # docker image push registry-host:5000/myadmin/rhel-httpd
-
-Check that this worked by running:
-
-    # docker image ls
-
-You should see both `rhel-httpd` and `registry-host:5000/myadmin/rhel-httpd`
-listed.

-Assigns a new alias to an image in a registry. An alias refers to the
-entire image name including the optional `TAG` after the ':'. 
-
-# OPTIONS
-**NAME**
-   The image name which is made up of slash-separated name components, 
-   optionally prefixed by a registry hostname. The hostname must comply with 
-   standard DNS rules, but may not contain underscores. If a hostname is 
-   present, it may optionally be followed by a port number in the format 
-   `:8080`. If not present, the command uses Docker's public registry located at
-   `registry-1.docker.io` by default. Name components may contain lowercase 
-   letters, digits and separators. A separator is defined as a period, one or
-   two underscores, or one or more dashes. A name component may not start or end 
-   with a separator.
-
-**TAG**
-   The tag assigned to the image to version and distinguish images with the same
-   name. The tag name must be valid ASCII and may contain lowercase and
-   uppercase letters, digits, underscores, periods and hyphens. A tag name
-   may not start with a period or a hyphen and may contain a maximum of 128
-   characters.
-
-# EXAMPLES
-
-## Tagging an image referenced by ID
-
-To tag a local image with ID "0e5574283393" into the "fedora" repository with 
-"version1.0":
-
-    docker image tag 0e5574283393 fedora/httpd:version1.0
-
-## Tagging an image referenced by Name
-
-To tag a local image with name "httpd" into the "fedora" repository with 
-"version1.0":
-
-    docker image tag httpd fedora/httpd:version1.0
-
-Note that since the tag name is not specified, the alias is created for an
-existing local version `httpd:latest`.
-
-## Tagging an image referenced by Name and Tag
-
-To tag a local image with name "httpd" and tag "test" into the "fedora"
-repository with "version1.0.test":
-
-    docker image tag httpd:test fedora/httpd:version1.0.test
-
-## Tagging an image for a private repository
-
-To push an image to a private registry and not the central Docker
-registry you must tag it with the registry hostname and port (if needed).
-
-    docker image tag 0e5574283393 myregistryhost:5000/fedora/httpd:version1.0

-
-You can also use the `docker run --network=<network-name>` option to start a container and immediately connect it to a network.
-
-```bash
-$ docker run -itd --network=multi-host-network --ip 172.20.88.22 --ip6 2001:db8::8822 busybox

-You can pause, restart, and stop containers that are connected to a network.
-A container connects to its configured networks when it runs.
-
-If specified, the container's IP address(es) is reapplied when a stopped
-container is restarted. If the IP address is no longer available, the container
-fails to start. One way to guarantee that the IP address is available is
-to specify an `--ip-range` when creating the network, and choose the static IP
-address(es) from outside that range. This ensures that the IP address is not
-given to another container while this container is not on the network.
-

-$ docker network create --subnet 172.20.0.0/16 --ip-range 172.20.240.0/20 multi-host-network

-Creates a new network. The `DRIVER` accepts `bridge` or `overlay` which are the
-built-in network drivers. If you have installed a third party or your own custom
-network driver you can specify that `DRIVER` here also. If you don't specify the
-`--driver` option, the command automatically creates a `bridge` network for you.
-When you install Docker Engine it creates a `bridge` network automatically. This
-network corresponds to the `docker0` bridge that Engine has traditionally relied
-on. When launch a new container with  `docker run` it automatically connects to
-this bridge network. You cannot remove this default bridge network but you can
-create new ones using the `network create` command.
-
-```bash
-$ docker network create -d bridge my-bridge-network
-```
-
-Bridge networks are isolated networks on a single Engine installation. If you
-want to create a network that spans multiple Docker hosts each running an
-Engine, you must create an `overlay` network. Unlike `bridge` networks overlay
-networks require some pre-existing conditions before you can create one. These
-conditions are:
-
-* Access to a key-value store. Engine supports Consul, Etcd, and Zookeeper (Distributed store) key-value stores.
-* A cluster of hosts with connectivity to the key-value store.
-* A properly configured Engine `daemon` on each host in the cluster.
-
-The `dockerd` options that support the `overlay` network are:
-
-* `--cluster-store`
-* `--cluster-store-opt`
-* `--cluster-advertise`
-
-To read more about these options and how to configure them, see ["*Get started
-with multi-host
-network*"](https://docs.docker.com/engine/userguide/networking/get-started-overlay/).
-
-It is also a good idea, though not required, that you install Docker Swarm on to
-manage the cluster that makes up your network. Swarm provides sophisticated
-discovery and server management that can assist your implementation.
-
-Once you have prepared the `overlay` network prerequisites you simply choose a
-Docker host in the cluster and issue the following to create the network:
-
-```bash
-$ docker network create -d overlay my-multihost-network
-```
-
-Network names must be unique. The Docker daemon attempts to identify naming
-conflicts but this is not guaranteed. It is the user's responsibility to avoid
-name conflicts.
-
-## Connect containers
-
-When you start a container use the `--network` flag to connect it to a network.
-This adds the `busybox` container to the `mynet` network.
-
-```bash
-$ docker run -itd --network=mynet busybox
-```
-
-If you want to add a container to a network after the container is already
-running use the `docker network connect` subcommand.
-
-You can connect multiple containers to the same network. Once connected, the
-containers can communicate using only another container's IP address or name.
-For `overlay` networks or custom plugins that support multi-host connectivity,
-containers connected to the same multi-host network but launched from different
-Engines can also communicate in this way.
-
-You can disconnect a container from a network using the `docker network
-disconnect` command.
-
-## Specifying advanced options
-
-When you create a network, Engine creates a non-overlapping subnetwork for the
-network by default. This subnetwork is not a subdivision of an existing network.
-It is purely for ip-addressing purposes. You can override this default and
-specify subnetwork values directly using the `--subnet` option. On a
-`bridge` network you can only create a single subnet:
-
-```bash
-$ docker network create -d bridge --subnet=192.168.0.0/16 br0
-```
-
-Additionally, you also specify the `--gateway` `--ip-range` and `--aux-address`
-options.
-
-```bash
-$ docker network create \
-  --driver=bridge \
-  --subnet=172.28.0.0/16 \
-  --ip-range=172.28.5.0/24 \
-  --gateway=172.28.5.254 \
-  br0
-```
-
-If you omit the `--gateway` flag the Engine selects one for you from inside a
-preferred pool. For `overlay` networks and for network driver plugins that
-support it you can create multiple subnetworks.
-
-```bash
-$ docker network create -d overlay \
-  --subnet=192.168.0.0/16 \
-  --subnet=192.170.0.0/16 \
-  --gateway=192.168.0.100 \ 
-  --gateway=192.170.0.100 \
-  --ip-range=192.168.1.0/24 \
-  --aux-address="my-router=192.168.1.5" --aux-address="my-switch=192.168.1.6" \
-  --aux-address="my-printer=192.170.1.5" --aux-address="my-nas=192.170.1.6" \
-  my-multihost-network
-```
-
-Be sure that your subnetworks do not overlap. If they do, the network create
-fails and Engine returns an error.
-
-### Network internal mode
-
-By default, when you connect a container to an `overlay` network, Docker also
-connects a bridge network to it to provide external connectivity. If you want
-to create an externally isolated `overlay` network, you can specify the
-`--internal` option.
-
-### Network ingress mode
-
-You can create the network which will be used to provide the routing-mesh in the
-swarm cluster. You do so by specifying `--ingress` when creating the network. Only
-one ingress network can be created at the time. The network can be removed only
-if no services depend on it. Any option available when creating a overlay network
-is also available when creating the ingress network, besides the `--attachable` option.
-
-```bash
-$ docker network create -d overlay \
-  --subnet=10.11.0.0/16 \
-  --ingress \
-  --opt com.docker.network.mtu=9216 \
-  --opt encrypted=true \
-  my-ingress-network
-```
-
-### Run services on predefined networks
-
-You can create services on the predefined docker networks `bridge` and `host`.
-
-```bash
-$ docker service create --name my-service \
-  --network host \
-  --replicas 2 \
-  busybox top
-```
-
-### Swarm networks with local scope drivers
-
-You can create a swarm network with local scope network drivers. You do so
-by promoting the network scope to `swarm` during the creation of the network. 
-You will then be able to use this network when creating services. 
-
-```bash
-$ docker network create -d bridge \
-  --scope swarm \
-  --attachable \
-  swarm-network
-```
-
-For network drivers which provide connectivity across hosts (ex. macvlan), if
-node specific configurations are needed in order to plumb the network on each
-host, you will supply that configuration via a configuration only network.
-When you create the swarm scoped network, you will then specify the name of the 
-network which contains the configuration.
-
-
-```bash
-node1$ docker network create --config-only --subnet 192.168.100.0/24 --gateway 192.168.100.115 mv-config
-node2$ docker network create --config-only --subnet 192.168.200.0/24 --gateway 192.168.200.202 mv-config
-node1$ docker network create -d macvlan --scope swarm --config-from mv-config --attachable swarm-network

-## Filtering
-
-The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there
-is more than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`).
-Multiple filter flags are combined as an `OR` filter. For example, 
-`-f type=custom -f type=builtin` returns both `custom` and `builtin` networks.
-
-The currently supported filters are:
-
-* driver
-* id (network's id)
-* label (`label=<key>` or `label=<key>=<value>`)
-* name (network's name)
-* scope (`swarm|global|local`)
-* type (custom|builtin)
-
-#### Driver
-
-The `driver` filter matches networks based on their driver.
-
-The following example matches networks with the `bridge` driver:
-
-```bash
-$ docker network ls --filter driver=bridge
-NETWORK ID          NAME                DRIVER
-db9db329f835        test1               bridge
-f6e212da9dfd        test2               bridge
-```
-
-#### ID
-
-The `id` filter matches on all or part of a network's ID.
-
-The following filter matches all networks with an ID containing the
-`63d1ff1f77b0...` string.
-
-```bash
-$ docker network ls --filter id=63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161
-NETWORK ID          NAME                DRIVER
-63d1ff1f77b0        dev                 bridge
-```
-
-You can also filter for a substring in an ID as this shows:
-
-```bash
-$ docker network ls --filter id=95e74588f40d
-NETWORK ID          NAME                DRIVER
-95e74588f40d        foo                 bridge
-
-$ docker network ls --filter id=95e
-NETWORK ID          NAME                DRIVER
-95e74588f40d        foo                 bridge
-```
-
-#### Label
-
-The `label` filter matches networks based on the presence of a `label` alone or a `label` and a
-value.
-
-The following filter matches networks with the `usage` label regardless of its value.
-
-```bash
-$ docker network ls -f "label=usage"
-NETWORK ID          NAME                DRIVER
-db9db329f835        test1               bridge              
-f6e212da9dfd        test2               bridge
-```
-
-The following filter matches networks with the `usage` label with the `prod` value.
-
-```bash
-$ docker network ls -f "label=usage=prod"
-NETWORK ID          NAME                DRIVER
-f6e212da9dfd        test2               bridge
-```
-
-#### Name
-
-The `name` filter matches on all or part of a network's name.
-
-The following filter matches all networks with a name containing the `foobar` string.
-
-```bash
-$ docker network ls --filter name=foobar
-NETWORK ID          NAME                DRIVER
-06e7eef0a170        foobar              bridge
-```
-
-You can also filter for a substring in a name as this shows:
-
-```bash
-$ docker network ls --filter name=foo
-NETWORK ID          NAME                DRIVER
-95e74588f40d        foo                 bridge
-06e7eef0a170        foobar              bridge
-```
-
-#### Scope
-
-The `scope` filter matches networks based on their scope.
-
-The following example matches networks with the `swarm` scope:
-
-```bash
-$ docker network ls --filter scope=swarm
-NETWORK ID          NAME                DRIVER              SCOPE
-xbtm0v4f1lfh        ingress             overlay             swarm
-ic6r88twuu92        swarmnet            overlay             swarm
-```
-
-The following example matches networks with the `local` scope:
-
-```bash
-$ docker network ls --filter scope=local
-NETWORK ID          NAME                DRIVER              SCOPE
-e85227439ac7        bridge              bridge              local
-0ca0e19443ed        host                host                local
-ca13cc149a36        localnet            bridge              local
-f9e115d2de35        none                null                local
-```
-
-#### Type
-
-The `type` filter supports two values; `builtin` displays predefined networks
-(`bridge`, `none`, `host`), whereas `custom` displays user defined networks.
-
-The following filter matches all user defined networks:
-
-```bash
-$ docker network ls --filter type=custom
-NETWORK ID          NAME                DRIVER
-95e74588f40d        foo                 bridge
-63d1ff1f77b0        dev                 bridge
-```
-
-By having this flag it allows for batch cleanup. For example, use this filter
-to delete all user defined networks:
-
-```bash
-$ docker network rm `docker network ls --filter type=custom -q`
-```
-
-A warning will be issued when trying to remove a network that has containers
-attached.
-
-## Format

-Removes one or more networks by name or identifier. To remove a network,
-you must first disconnect any containers connected to it.
-To remove the network named 'my-network':
-
-```bash

-```
-
-To delete multiple networks in a single `docker network rm` command, provide
-multiple network names or ids. The following example deletes a network with id
-`3695c422697f` and a network named `my-network`:
-
-```bash
-  $ docker network rm 3695c422697f my-network

-
-When you specify multiple networks, the command attempts to delete each in turn.
-If the deletion of one network fails, the command continues to the next on the
-list and tries to delete that. The command reports success or failure for each
-deletion.

-    delete, import, load, pull, push, save, tag, untag
-
-Docker volumes report the following events:
-
-    create, mount, unmount, destroy
-
-Docker networks report the following events:
-
-    create, connect, disconnect, destroy
-
-# OPTIONS
-
-The `--since` and `--until` parameters can be Unix timestamps, date formatted
-timestamps, or Go duration strings (e.g. `10m`, `1h30m`) computed
-relative to the client machine's time. If you do not provide the `--since` option,
-the command returns only new and/or live events.  Supported formats for date
-formatted time stamps include RFC3339Nano, RFC3339, `2006-01-02T15:04:05`,
-`2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
-timezone on the client will be used if you do not provide either a `Z` or a
-`+-00:00` timezone offset at the end of the timestamp.  When providing Unix
-timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
-that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
-seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
-fraction of a second no more than nine digits long.

-# EXAMPLES
-
-## Listening for Docker events
-
-After running docker events a container 786d698004576 is started and stopped
-(The container name has been shortened in the output below):
-
-    # docker events
-    2015-01-28T20:21:31.000000000-08:00 59211849bc10: (from whenry/testimage:latest) start

-    2015-01-28T20:21:32.000000000-08:00 59211849bc10: (from whenry/testimage:latest) stop
-
-## Listening for events since a given date
-Again the output container IDs have been shortened for the purposes of this document:
-
-    # docker events --since '2015-01-28'
-    2015-01-28T20:25:38.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) create

-    2015-01-28T20:25:39.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) create
-    2015-01-28T20:25:39.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) start
-    2015-01-28T20:25:40.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) die
-    2015-01-28T20:25:42.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) stop
-    2015-01-28T20:25:45.000000000-08:00 c21f6c22ba27: (from whenry/testimage:latest) start

-
-The following example outputs all events that were generated in the last 3 minutes,
-relative to the current time on the client machine:
-
-    # docker events --since '3m'
-    2015-05-12T11:51:30.999999999Z07:00  4386fb97867d: (from ubuntu-1:14.04) die
-    2015-05-12T15:52:12.999999999Z07:00  4386fb97867d: (from ubuntu-1:14.04) stop
-    2015-05-12T15:53:45.999999999Z07:00  7805c1d35632: (from redis:2.8) die
-    2015-05-12T15:54:03.999999999Z07:00  7805c1d35632: (from redis:2.8) stop
-
-If you do not provide the --since option, the command returns only new and/or
-live events.
-
-## Format
-
-If a format (`--format`) is specified, the given template will be executed
-instead of the default format. Go's **text/template** package describes all the
-details of the format.
-
-    # docker events --filter 'type=container' --format 'Type={{.Type}}  Status={{.Status}}  ID={{.ID}}'
-    Type=container  Status=create  ID=2ee349dac409e97974ce8d01b70d250b85e0ba8189299c126a87812311951e26

-The `docker volume` command has subcommands for managing data volumes. A data
-volume is a specially-designated directory that by-passes storage driver
-management.
-
-Data volumes persist data independent of a container's life cycle. When you
-delete a container, the Docker daemon does not delete any data volumes. You can
-share volumes across multiple containers. Moreover, you can share data volumes
-with other computing resources in your system.
-
-To see help for a subcommand, use:
-
-    docker volume COMMAND --help
-
-For full details on using docker volume visit Docker's online documentation.

-Creates a new volume that containers can consume and store data in. If a name
-is not specified, Docker generates a random name. You create a volume and then
-configure the container to use it, for example:
-
-    $ docker volume create hello
-    hello
-    $ docker run -d -v hello:/world busybox ls /world
-
-The mount is created inside the container's `/src` directory. Docker doesn't
-not support relative paths for mount points inside the container.
-
-Multiple containers can use the same volume in the same time period. This is
-useful if two containers need access to shared data. For example, if one
-container writes and the other reads the data.
-
-## Driver specific options
-
-Some volume drivers may take options to customize the volume creation. Use the
-`-o` or `--opt` flags to pass driver options:
-
-    $ docker volume create --driver fake --opt tardis=blue --opt timey=wimey
-
-These options are passed directly to the volume driver. Options for different
-volume drivers may do different things (or nothing at all).
-
-The built-in `local` driver on Windows does not support any options.
-
-The built-in `local` driver on Linux accepts options similar to the linux
-`mount` command:
-
-    $ docker volume create --driver local --opt type=tmpfs --opt device=tmpfs --opt o=size=100m,uid=1000
-
-Another example:
-
-    $ docker volume create --driver local --opt type=btrfs --opt device=/dev/sda2

Subject: [PATCH 108/191] When daemon is in startup process, could not start
 container

Description:
 When docker is in startup process and containerd sends an "process exit" event to docker.
 If the container config '--restart=always', restartmanager will start this container very soon.

 But some initialization is not done, e.g. `daemon.netController`,when visit, docker would panic.

Subject: [PATCH 113/191] Redact the swarm's spec's signing CA cert when
 getting swarm info, because otherwise if the user gets the info from the API,
 makes a non-CA related change, then updates, swarm will interpret this as the
 user trying to remove the signing key from the swarm.  We are redacting due
 to usability reasons, not because the signing cert is secret.  The signing
 KEY is secret, hence it's redacted.

Subject: [PATCH 115/191] Don't chown/chmod volumes if not needed.

Doing a chown/chmod automatically can cause `EPERM` in some cases (e.g.
with an NFS mount). Currently Docker will always call chown+chmod on a
volume path unless `:nocopy` is passed in, but we don't need to make
these calls if the perms and ownership already match and potentially
avoid an uneccessary `EPERM`.

Subject: [PATCH 118/191] devmapper: ensure that UdevWait is called after calls
 to setCookie

Recent changes to devmapper broke the implicit requirement that UdevWait be
called after every call to task.setCookie.  Failure to do so results in leaks of
semaphores in the LVM code, eventually leading to semaphore exhaustion.
Previously this was handled by calling UdevWait in a ubiquitous defer function.
While there was initially some concern with deferring the UdevWait function
would cause some amount of race possibiliy, the fact that we never return the
cookie value or any value used to find it, makes that possibility seem unlikely,
so lets go back to that method

Subject: [PATCH 128/191] image: Improve store locking

This showed up in a recent profile.

Search doesn't need to take a lock on the store, because digestset has
its own locking.

Some other methods can get by with a read lock instead of an exclusive
lock.

-# PKCS#11 [![Build Status](https://travis-ci.org/miekg/pkcs11.png?branch=master)](https://travis-ci.org/miekg/pkcs11)
-
-This is a Go implementation of the PKCS#11 API. It wraps the library closely, but uses Go idiom
-were it makes sense. It has been tested with SoftHSM.
-
-## SoftHSM
-
-* Make it use a custom configuration file `export SOFTHSM_CONF=$PWD/softhsm.conf`
-
-* Then use `softhsm` to init it
-
-        softhsm --init-token --slot 0 --label test --pin 1234
-
-* Then use `libsofthsm.so` as the pkcs11 module:
-
-        p := pkcs11.New("/usr/lib/softhsm/libsofthsm.so")
-
-## Examples
-
-A skeleton program would look somewhat like this (yes, pkcs#11 is verbose):
-
-    p := pkcs11.New("/usr/lib/softhsm/libsofthsm.so")
-    err := p.Initialize()
-    if err != nil {
-        panic(err)
-    }
-
-    defer p.Destroy()
-    defer p.Finalize()
-
-    slots, err := p.GetSlotList(true)
-    if err != nil {
-        panic(err)
-    }
-
-    session, err := p.OpenSession(slots[0], pkcs11.CKF_SERIAL_SESSION|pkcs11.CKF_RW_SESSION)
-    if err != nil {
-        panic(err)
-    }
-    defer p.CloseSession(session)
-
-    err = p.Login(session, pkcs11.CKU_USER, "1234")
-    if err != nil {
-        panic(err)
-    }
-    defer p.Logout(session)
-
-    p.DigestInit(session, []*pkcs11.Mechanism{pkcs11.NewMechanism(pkcs11.CKM_SHA_1, nil)})
-    hash, err := p.Digest(session, []byte("this is a string"))
-    if err != nil {
-        panic(err)
-    }
-
-    for _, d := range hash {
-            fmt.Printf("%x", d)
-    }
-    fmt.Println()
-
-Further examples are included in the tests.
-
-# TODO
-
-* Fix/double check endian stuff, see types.go NewAttribute()
-* Look at the memory copying in fast functions (sign, hash etc)

-/* Before including this file (pkcs11.h) (or pkcs11t.h by
- * itself), 6 platform-specific macros must be defined.  These
- * macros are described below, and typical definitions for them
- * are also given.  Be advised that these definitions can depend
- * on both the platform and the compiler used (and possibly also
- * on whether a Cryptoki library is linked statically or
- * dynamically).
- *
- * In addition to defining these 6 macros, the packing convention
- * for Cryptoki structures should be set.  The Cryptoki
- * convention on packing is that structures should be 1-byte
- * aligned.
- *
- * If you're using Microsoft Developer Studio 5.0 to produce
- * Win32 stuff, this might be done by using the following
- * preprocessor directive before including pkcs11.h or pkcs11t.h:
- *
- * #pragma pack(push, cryptoki, 1)
- *
- * and using the following preprocessor directive after including
- * pkcs11.h or pkcs11t.h:
- *
- * #pragma pack(pop, cryptoki)
- *
- * If you're using an earlier version of Microsoft Developer
- * Studio to produce Win16 stuff, this might be done by using
- * the following preprocessor directive before including
- * pkcs11.h or pkcs11t.h:
- *
- * #pragma pack(1)
- *
- * In a UNIX environment, you're on your own for this.  You might
- * not need to do (or be able to do!) anything.
- *
- *
- * Now for the macros:
- *
- *
- * 1. CK_PTR: The indirection string for making a pointer to an
- * object.  It can be used like this:
- *
- * typedef CK_BYTE CK_PTR CK_BYTE_PTR;
- *
- * If you're using Microsoft Developer Studio 5.0 to produce
- * Win32 stuff, it might be defined by:
- *
- * #define CK_PTR *
- *
- * If you're using an earlier version of Microsoft Developer
- * Studio to produce Win16 stuff, it might be defined by:
- *
- * #define CK_PTR far *
- *
- * In a typical UNIX environment, it might be defined by:
- *
- * #define CK_PTR *
- *
- *
- * 2. CK_DEFINE_FUNCTION(returnType, name): A macro which makes
- * an exportable Cryptoki library function definition out of a
- * return type and a function name.  It should be used in the
- * following fashion to define the exposed Cryptoki functions in
- * a Cryptoki library:
- *
- * CK_DEFINE_FUNCTION(CK_RV, C_Initialize)(
- *   CK_VOID_PTR pReserved
- * )
- * {
- *   ...
- * }
- *
- * If you're using Microsoft Developer Studio 5.0 to define a
- * function in a Win32 Cryptoki .dll, it might be defined by:
- *
- * #define CK_DEFINE_FUNCTION(returnType, name) \
- *   returnType __declspec(dllexport) name
- *
- * If you're using an earlier version of Microsoft Developer
- * Studio to define a function in a Win16 Cryptoki .dll, it
- * might be defined by:
- *
- * #define CK_DEFINE_FUNCTION(returnType, name) \
- *   returnType __export _far _pascal name
- *
- * In a UNIX environment, it might be defined by:
- *
- * #define CK_DEFINE_FUNCTION(returnType, name) \
- *   returnType name
- *
- *
- * 3. CK_DECLARE_FUNCTION(returnType, name): A macro which makes
- * an importable Cryptoki library function declaration out of a
- * return type and a function name.  It should be used in the
- * following fashion:
- *
- * extern CK_DECLARE_FUNCTION(CK_RV, C_Initialize)(
- *   CK_VOID_PTR pReserved
- * );
- *
- * If you're using Microsoft Developer Studio 5.0 to declare a
- * function in a Win32 Cryptoki .dll, it might be defined by:
- *
- * #define CK_DECLARE_FUNCTION(returnType, name) \
- *   returnType __declspec(dllimport) name
- *
- * If you're using an earlier version of Microsoft Developer
- * Studio to declare a function in a Win16 Cryptoki .dll, it
- * might be defined by:
- *
- * #define CK_DECLARE_FUNCTION(returnType, name) \
- *   returnType __export _far _pascal name
- *
- * In a UNIX environment, it might be defined by:
- *
- * #define CK_DECLARE_FUNCTION(returnType, name) \
- *   returnType name
- *
- *
- * 4. CK_DECLARE_FUNCTION_POINTER(returnType, name): A macro
- * which makes a Cryptoki API function pointer declaration or
- * function pointer type declaration out of a return type and a
- * function name.  It should be used in the following fashion:
- *
- * // Define funcPtr to be a pointer to a Cryptoki API function
- * // taking arguments args and returning CK_RV.
- * CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtr)(args);
- *
- * or
- *
- * // Define funcPtrType to be the type of a pointer to a
- * // Cryptoki API function taking arguments args and returning
- * // CK_RV, and then define funcPtr to be a variable of type
- * // funcPtrType.
- * typedef CK_DECLARE_FUNCTION_POINTER(CK_RV, funcPtrType)(args);
- * funcPtrType funcPtr;
- *
- * If you're using Microsoft Developer Studio 5.0 to access
- * functions in a Win32 Cryptoki .dll, in might be defined by:
- *
- * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
- *   returnType __declspec(dllimport) (* name)
- *
- * If you're using an earlier version of Microsoft Developer
- * Studio to access functions in a Win16 Cryptoki .dll, it might
- * be defined by:
- *
- * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
- *   returnType __export _far _pascal (* name)
- *
- * In a UNIX environment, it might be defined by:
- *
- * #define CK_DECLARE_FUNCTION_POINTER(returnType, name) \
- *   returnType (* name)
- *
- *
- * 5. CK_CALLBACK_FUNCTION(returnType, name): A macro which makes
- * a function pointer type for an application callback out of
- * a return type for the callback and a name for the callback.
- * It should be used in the following fashion:
- *
- * CK_CALLBACK_FUNCTION(CK_RV, myCallback)(args);
- *
- * to declare a function pointer, myCallback, to a callback
- * which takes arguments args and returns a CK_RV.  It can also
- * be used like this:
- *
- * typedef CK_CALLBACK_FUNCTION(CK_RV, myCallbackType)(args);
- * myCallbackType myCallback;
- *
- * If you're using Microsoft Developer Studio 5.0 to do Win32
- * Cryptoki development, it might be defined by:
- *
- * #define CK_CALLBACK_FUNCTION(returnType, name) \
- *   returnType (* name)
- *
- * If you're using an earlier version of Microsoft Developer
- * Studio to do Win16 development, it might be defined by:
- *
- * #define CK_CALLBACK_FUNCTION(returnType, name) \
- *   returnType _far _pascal (* name)
- *
- * In a UNIX environment, it might be defined by:
- *
- * #define CK_CALLBACK_FUNCTION(returnType, name) \
- *   returnType (* name)
- *
- *
- * 6. NULL_PTR: This macro is the value of a NULL pointer.
- *
- * In any ANSI/ISO C environment (and in many others as well),
- * this should best be defined by
- *
- * #ifndef NULL_PTR
- * #define NULL_PTR 0
- * #endif

Subject: [PATCH 158/191] Don't json marshal then immediately unmarshal

During container startup we end up spending a fair amount of time
encoding/decoding json.
This cuts out some of that since we already have the decoded object in
memory.

The old flow looked like:

1. Start container request
2. Create file
3. Encode container spec to json
4. Write to file
5. Close file
6. Open file
7. Read file
8. Decode container spec
9. Close file
10. Send to containerd.

The new flow cuts out steps 6-9 completely, and with it a lot of time
spent in reflect and file IO.

Subject: [PATCH 161/191] Remove deprecated contrib/mkimage-xyz scripts

The contrib/mkimage-busybox.sh, contrib/mkimage-debootstrap.sh,
and  contrib/mkimage-rinse.sh were deprecated in commit
51f707cf9dfb2dbe31cfd0cd92b922ca5d98e842, in favor of
their equivalents in contrib/mkimage/

Given that the deprecation warning has been in place
for over three years, it's save to now remove these.

+
+        ### Hijacking
+
+        This endpoint hijacks the HTTP connection to HTTP2 transport that allows the client to expose gPRC services on that connection.
+
+        For example, the client sends this request to upgrade the connection:
+
+        ```
+        POST /session HTTP/1.1
+        Upgrade: h2c
+        Connection: Upgrade
+        ```
+
+        The Docker daemon will respond with a `101 UPGRADED` response follow with the raw stream:
+
+        ```
+        HTTP/1.1 101 UPGRADED
+        Connection: Upgrade

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "{}"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

Subject: [PATCH 184/191] save deep copies of Container in the replica store

Reuse existing structures and rely on json serialization to deep copy
Container objects.

Also consolidate all "save" operations on container.CheckpointTo, which
now both saves a serialized json to disk, and replicates state to the
ACID in-memory store.

Subject: [PATCH 191/191] Fix autogen vars

commit ea2e4d73c4c753cdc99966e4dfe35143e79564ce removed the autogen
script, but if you happen to clone the dir fresh from git, you can't
build the integration test binaries.
