This link worked on GitHub, but was broken on docs.docker.com, so
replacing with a regular link directly to the docs instead.

032e485e1c ForwardAllSignals: check if channel is closed, and remove warning
Commit fff164c22e modified ForwardAllSignals to
take `SIGURG` signals into account, which can be generated by the Go runtime
on Go 1.14 and up as an interrupt to support pre-emptable system calls on Linux.

With the updated code, the signal (`s`) would sometimes be `nil`, causing spurious
(but otherwise harmless) warnings to be printed;

    Unsupported signal: <nil>. Discarding.

To debug this issue, I patched v20.10.4 to handle `nil`, and added a debug line
to print the signal in all cases;

```patch

This patch checks if the channel is closed, and removes the warning (to prevent warnings if new
signals are added that are not in our known list of signals)

We should also consider updating `notfiyAllSignals()`, which currently forwards
_all_ signals (`signal.Notify(sigc)` without passing a list of signals), and
instead pass it "all signals _minus_ the signals we don't want forwarded":

4571d90f20 config: print deprecation warning when falling back to ~/.dockercfg
Relates to the deprecation, added in 3c0a167ed5

The docker CLI up until v1.7.0 used the `~/.dockercfg` file to store credentials
after authenticating to a registry (`docker login`). Docker v1.7.0 replaced this
file with a new CLI configuration file, located in `~/.docker/config.json`. When
implementing the new configuration file, the old file (and file-format) was kept
as a fall-back, to assist existing users with migrating to the new file.

Given that the old file format encourages insecure storage of credentials
(credentials are stored unencrypted), and that no version of the CLI since
Docker v1.7.0 has created this file, the file is marked deprecated, and support
for this file will be removed in a future release.

This patch adds a deprecation warning, which is printed if the CLI falls back
to using the deprecated ~/.dockercfg file.

d6eeeb6259 service rollback: always verify state
Prior to this change, progressbars would sometimes be hidden, and the function
would return early. In addition, the direction of the progressbars would sometimes
be "incrementing" (similar to "docker service update"), and sometimes be "decrementing"
(to indicate a "rollback" is being performed).

This fix makes sure that we always proceed with the "verifying" step, and now
prints a message _after_ the verifying stage was completed;

    $ echo $?

    $ docker service rollback foo

    service rolled back: rollback completed

    $ echo $?

Remaining issues with reconciliation
--------------------------------------------

Note that both before, and after this change, the command sometimes terminates
early, and does not wait for the service to reconcile; this is most apparent
when rolling back is scaling up (so more tasks are deployed);

    $ docker service rollback foo
    foo
    service rolled back: rollback completed

    $ docker service rollback foo
    foo
    rollback: manually requested rollback

376b99c6d6 Rename bin/md2man to bin/go-md2man
In the recent PR !2877, some code was added to check if md2man is
already installed in the build environment. This is to cater to the
needs of Linux distributions.

However it turns out that Linux distributions install md2man as
bin/go-md2man instead of bin/md2man, hence the PR !2877 doesn't help
much.

This commit fixes it by settling on using the binary name go-md2man.

For reference, here the file list of the package go-md2man in several
distributions:

- Debian: <https://packages.debian.org/sid/amd64/go-md2man/filelist>
- Ubuntu: <https://packages.ubuntu.com/hirsute/amd64/go-md2man/filelist>

de40c2b172 Fix panic when failing to get DefaultAuthConfig
Commit f32731f902 fixed a potential panic
when an error was returned while trying to get existing credentials.

However, other code paths currently use the result of `GetDefaultAuthConfig()`
even in an error condition; this resulted in a panic, because a `nil` was
returned.

d513e46bfc cli/config: prevent warning if HOME is not set
commit c2626a8270 replaced the use of
github.com/docker/docker/pkg/homedir with Golang's os.UserHomeDir().

This change was partially reverted in 7a279af43d
to account for situations where `$HOME` is not set.

In  situations where no configuration file is present in `~/.config/`, the CLI
falls back to looking for the (deprecated) `~/.dockercfg` configuration file,
which was still using `os.UserHomeDir()`, which produces an error/warning if
`$HOME` is not set.

This patch introduces a helper function and a global variable to get the user's
home-directory. The global variable is used to prevent repeatedly looking up
the user's information (which, depending on the setup can be a costly operation).

48d30b5b32 Use golang.org/x/sys/execabs
On Windows, the os/exec.{Command,CommandContext,LookPath} functions
resolve command names that have neither path separators nor file extension
(e.g., "git") by first looking in the current working directory before
looking in the PATH environment variable.
Go maintainers intended to match cmd.exe's historical behavior.

However, this is pretty much never the intended behavior and as an abundance of precaution
this patch prevents that when executing commands.
Example of commands that docker.exe may execute: `git`, `docker-buildx` (or other cli plugin), `docker-credential-wincred`, `docker`.

Note that this was prompted by the [Go 1.15.7 security fixes](https://blog.golang.org/path-security), but unlike in `go.exe`,
the windows path lookups in docker are not in a code path allowing remote code execution, thus there is no security impact on docker.

Specifying blkio weight (`docker run --blkio-weight` and `docker run --blkio-weight-device`)
is now marked as deprecated when using cgroups v1 because the corresponding features
were [removed in Linux kernel v5.0 and up](https://github.com/torvalds/linux/commit/f382fb0bcef4c37dc049e9f6963e3baf204d815c).

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.
By default, the build cache is based on results from previous builds on the machine
on which you are building. The `--cache-from` option also allows you to use a
build-cache that's distributed through an image registry refer to the
[specifying external cache sources](commandline/build.md#specifying-external-cache-sources)
section in the `docker build` command reference.
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).
When you're done with your build, you're ready to look into [scanning your image with `docker scan`](https://docs.docker.com/engine/scan/),

### Official releases
Docker distributes official versions of the images that can be used for building
Dockerfiles under `docker/dockerfile` repository on Docker Hub. There are two
channels where new images are released: stable and experimental.
channels where new images are released: `stable` and `labs`.
Stable channel follows semantic versioning. For example:
Stable channel follows [semantic versioning](https://semver.org). For example:
- `docker/dockerfile:1.0.0` - only allow immutable version `1.0.0`
- `docker/dockerfile:1.0` - allow versions `1.0.*`
- `docker/dockerfile:1` - allow versions `1.*.*`
- `docker/dockerfile:latest` - latest release on stable channel
- `docker/dockerfile:1` - kept updated with the latest `1.x.x` minor _and_ patch release
- `docker/dockerfile:1.2` - kept updated with the latest `1.2.x` patch release,
and stops receiving updates once version `1.3.0` is released.
- `docker/dockerfile:1.2.1` - immutable: never updated
The experimental channel uses incremental versioning with the major and minor
component from the stable channel on the time of the release. For example:
We recommend using `docker/dockerfile:1`, which always points to the latest stable
release of the version 1 syntax, and receives both "minor" and "patch" updates
for the version 1 release cycle. BuildKit automatically checks for updates of the
syntax when performing a build, making sure you are using the most current version.
- `docker/dockerfile:1.0.1-experimental` - only allow immutable version `1.0.1-experimental`
- `docker/dockerfile:1.0-experimental` - latest experimental releases after `1.0`
- `docker/dockerfile:experimental` - latest release on experimental channel
If a specific version is used, such as `1.2` or `1.2.1`, the Dockerfile needs to
be updated manually to continue receiving bugfixes and new features. Old versions
of the Dockerfile remain compatible with the new versions of the builder.
You should choose a channel that best fits your needs. If you only want
bugfixes, you should use `docker/dockerfile:1.0`. If you want to benefit from
experimental features, you should use the experimental channel. If you are using
the experimental channel, newer releases may not be backwards compatible, so it
**labs channel**
The "labs" channel provides early access to Dockerfile features that are not yet
available in the stable channel. Labs channel images are released in conjunction
with the stable releases, and follow the same versioning with the `-labs` suffix,
for example:
- `docker/dockerfile:labs` - latest release on labs channel
- `docker/dockerfile:1-labs` - same as `dockerfile:1` in the stable channel, with labs features enabled
- `docker/dockerfile:1.2-labs` - same as `dockerfile:1.2` in the stable channel, with labs features enabled
- `docker/dockerfile:1.2.1-labs` - immutable: never updated. Same as `dockerfile:1.2.1` in the stable channel, with labs features enabled
Choose a channel that best fits your needs; if you want to benefit from
new features, use the labs channel. Images in the labs channel provide a superset
of the features in the stable channel; note that `stable` features in the labs
channel images follow [semantic versioning](https://semver.org), but "labs"
features do not, and newer releases may not be backwards compatible, so it
is recommended to use an immutable full version variant.
For master builds and nightly feature releases refer to the description in
[the source repository](https://github.com/moby/buildkit/blob/master/README.md).
For documentation on "labs" features, master builds, and nightly feature releases,
refer to the description in [the BuildKit source repository on GitHub](https://github.com/moby/buildkit/blob/master/README.md).

## External implementation features
This feature is only available when using the [BuildKit](#buildkit) backend.
Docker build supports experimental features like cache mounts, build secrets and
ssh forwarding that are enabled by using an external implementation of the
builder with a syntax directive. To learn about these features,
[refer to the documentation in BuildKit repository](https://github.com/moby/buildkit/blob/master/frontend/dockerfile/docs/experimental.md).

## Environment variables
For easy reference, the following list of environment variables are supported
by the `docker` command line:
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_HOST` Daemon socket to connect to.
* `DOCKER_STACK_ORCHESTRATOR` Configure the default orchestrator to use when using `docker stack` management commands.
* `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_CONTEXT` Specify the context to use (overrides DOCKER_HOST env var and default context set with "docker context use")
* `DOCKER_DEFAULT_PLATFORM` Specify the default platform for the commands that take the `--platform` flag.
#### Shared Environment variables
These environment variables can be used both with the `docker` command line and
`dockerd` command line:
* `DOCKER_CERT_PATH` The location of your authentication keys.
* `DOCKER_TLS_VERIFY` When set Docker uses TLS and verifies the remote.

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 configs, refer to [store configuration data using Docker Configs](https://docs.docker.com/engine/swarm/configs/).

>
> This is a cluster management command, and must be executed on a swarm
> manager node. To learn about managers and workers, refer to the

## Examples
### Inspect a config by name or ID
You can inspect a config, either by its *name*, or *ID*
For example, given the following config:
```bash
$ docker config ls
ID NAME CREATED UPDATED
eo7jnzguqgtpdah3cm5srfb97 my_config 3 minutes ago 3 minutes ago
```
```bash
$ docker config inspect config.json
```
The output is in JSON format, for example:
```json
[
{
"ID": "eo7jnzguqgtpdah3cm5srfb97",
"Version": {
"Index": 17
},
"CreatedAt": "2017-03-24T08:15:09.735271783Z",
"UpdatedAt": "2017-03-24T08:15:09.735271783Z",
"Spec": {
"Name": "my_config",
"Labels": {
"env": "dev",
"rev": "20170324"
},
"Data": "aGVsbG8K"
}
}
]
```
### Formatting
You can use the --format option to obtain specific information about a
config. The following example command outputs the creation time of the
config.
```bash
$ docker config inspect --format='{{.CreatedAt}}' eo7jnzguqgtpdah3cm5srfb97

## Description

> **Note**
>
> This is a cluster management command, and must be executed on a swarm
> manager node. To learn about managers and workers, refer to the
> [Swarm mode section](https://docs.docker.com/engine/swarm/) in the

## Examples
```bash
$ docker config ls
ID NAME CREATED UPDATED
6697bflskwj1998km1gnnjr38 q5s5570vtvnimefos1fyeo2u2 6 weeks ago 6 weeks ago

mem02h8n73mybpgqjf0kfi1n0 test_config 3 seconds ago 3 seconds ago
```
### 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](#id) (config's ID)
- [label](#label) (`label=<key>` or `label=<key>=<value>`)
- [name](#name) (config's name)
#### id
The `id` filter matches all or prefix of a config's id.
```bash
$ docker config ls -f "id=6697bflskwj1998km1gnnjr38"
ID NAME CREATED UPDATED
6697bflskwj1998km1gnnjr38 q5s5570vtvnimefos1fyeo2u2 6 weeks ago 6 weeks ago
```
#### label
The `label` filter matches configs based on the presence of a `label` alone or
a `label` and a value.
The following filter matches all configs with a `project` label regardless of
its value:
```bash
$ docker config ls --filter label=project
ID NAME CREATED UPDATED
mem02h8n73mybpgqjf0kfi1n0 test_config 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_config About an hour ago About an hour ago
```
#### name
The `name` filter matches on all or prefix of a config's name.
The following filter matches config with a name containing a prefix of `test`.
```bash
$ docker config ls --filter name=test_config
ID NAME CREATED UPDATED
mem02h8n73mybpgqjf0kfi1n0 test_config About an hour ago About an hour ago
```
### Format the output
The formatting option (`--format`) pretty prints configs output
using a Go template.
Valid placeholders for the Go template are listed below:
| Placeholder | Description |
| ------------ | ------------------------------------------------------------------------------------ |
| `.ID` | Config ID |
| `.Name` | Config name |
| `.CreatedAt` | Time when the config was created |
| `.UpdatedAt` | Time when the config was updated |
| `.Labels` | All labels assigned to the config |
| `.Label` | Value of a specific label for this config. For example `{{.Label "my-label"}}` |
When using the `--format` option, the `config 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 config ls --format "{{.ID}}: {{.Name}}"
77af4d6b9913: config-1
b6fa739cedf5: config-2
78a85c484f71: config-3
```
To list all configs with their name and created date in a table format you
can use:
```bash
$ docker config ls --format "table {{.ID}}\t{{.Name}}\t{{.CreatedAt}}"
ID NAME CREATED
77af4d6b9913 config-1 5 minutes ago
b6fa739cedf5 config-2 3 hours ago
78a85c484f71 config-3 10 days ago
```

### Remove all stopped containers
```bash
$ docker rm $(docker ps -a -q)
Use the [`docker container prune`](container_prune.md) command to remove all
stopped containers, or refer to the [`docker system prune`](system_prune.md)
command to remove unused containers in addition to other Docker resources, such
as (unused) images and networks.
Alternatively, you can use the `docker ps` with the `-q` / `--quiet` option to
generate a list of container IDs to remove, and use that list as argument for
the `docker rm` command.
Combining commands can be more flexible, but is less portable as it depends
on features provided by the shell, and the exact syntax may differ depending on
what shell is used. To use this approach on Windows, consider using PowerShell
or Bash.
The example below uses `docker ps -q` to print the IDs of all containers that
have exited (`--filter status=exited`), and removes those containers with
the `docker rm` command:
```console
$ docker rm $(docker ps --filter status=exited -q)
```
This command deletes all stopped containers. The command
`docker ps -a -q` above returns all existing container IDs and passes them to
the `rm` command which deletes them. Running containers are not deleted.
Or, using the `xargs` Linux utility;
```console
$ docker ps --filter status=exited -q | xargs docker rm
```

# 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/network/network-tutorial-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 require using Docker
experimental features to be enabled.
- All of the examples can be performed on a single host running Docker. Any
example 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`
- 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 follows:
```bash
$ 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:
```bash
# 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`.
```bash
# 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:
```bash
# 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.
```bash
# 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.
```bash
# 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.
```bash
$$ 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).
```bash
$ 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=`.
```bash
$$ 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 than rejecting the network
creation and isolating containers from only communicating with one another.
```bash
# 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 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
```

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`.
```bash
# 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:
```bash
# Inside the IPv6 container
$$ ip a show eth0
75: eth0@if55: <BROADCAST,MULTICAST,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

valid_lft forever preferred_lft forever
inet6 2001:db8:abc2::1/64 scope link nodad
valid_lft forever preferred_lft forever
$$ ip -6 route

2001:db8:abc2::/64 dev eth0 proto kernel metric 256
default via 2001:db8:abc2::22 dev eth0 metric 1024
```
Start a second container and ping the first container's v6 address.
```bash
# Test L2 connectivity over IPv6
$ docker run --net=v6ipvlan139 -it --rm alpine /bin/sh
# Inside the second IPv6 container
$$ ip a show eth0
75: eth0@if55: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default

2 packets transmitted, 2 packets received, 0% packet loss
round-trip min/avg/max/stddev = 0.044/0.051/0.058/0.000 ms
```
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:
```bash
$ docker network create -d ipvlan \
--subnet=192.168.140.0/24 --subnet=192.168.142.0/24 \
--gateway=192.168.140.1 --gateway=192.168.142.1 \
--subnet=2001:db8:abc9::/64 --gateway=2001:db8:abc9::22 \
-o parent=eth0.140 \
-o ipvlan_mode=l2 ipvlan140
```
Start a container and view eth0 and both v4 & v6 routing tables:
```bash
$ docker run --net=ipvlan140 --ip6=2001:db8:abc2::51 -it --rm alpine /bin/sh
$ ip a show eth0
78: eth0@if77: <BROADCAST,MULTICAST,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 192.168.140.2/24 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:abc9::1/64 scope link nodad
valid_lft forever preferred_lft forever
$$ ip route
default via 192.168.140.1 dev eth0
192.168.140.0/24 dev eth0 proto kernel scope link src 192.168.140.2
$$ ip -6 route
2001:db8:abc4::/64 dev eth0 proto kernel metric 256
2001:db8:abc9::/64 dev eth0 proto kernel metric 256
default via 2001:db8:abc9::22 dev eth0 metric 1024
```
Start a second container with a specific `--ip4` address and ping the first host
using IPv4 packets:
```bash
$ 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.
```bash
# 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:
```bash
$$ ip a show eth0
63: eth0@if59: <BROADCAST,MULTICAST,NOARP,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default
link/ether 00:50:56:2b:29:40 brd ff:ff:ff:ff:ff:ff
inet 192.168.112.2/24 scope global eth0
valid_lft forever preferred_lft forever
inet6 2001:db8:abc4::250:56ff:fe2b:2940/64 scope link
valid_lft forever preferred_lft forever
inet6 2001:db8:abc6::10/64 scope link nodad
valid_lft forever preferred_lft forever
# Note the default route is simply the eth device because ARPs are filtered.
$$ 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:abc6::/64 dev eth0 proto kernel metric 256
default dev eth0 metric 1024
```

### 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`.
```bash
# 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:
```bash
# 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:
```bash
$ 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.
