This patch adds annotations to mark the checkpoint commands as Linux only, which
hides them if the daemon is running a non-matching operating-system type;
Before:
docker
Usage: docker COMMAND
A self-sufficient runtime for containers
...
Management Commands:
config Manage Docker configs
container Manage containers
image Manage images
After:
docker
Usage: docker COMMAND
A self-sufficient runtime for containers
...
Management Commands:
checkpoint Manage checkpoints
config Manage Docker configs
container Manage containers
image Manage images
This change also prints errors when attempting to use checkpoint commands or
flags if the feature is not supported by the Daemon's operating system;
$ docker checkpoint --help
docker checkpoint is only supported on a Docker daemon running on linux, but the Docker daemon is running on windows
$ docker checkpoint create --help
docker checkpoint create is only supported on a Docker daemon running on linux, but the Docker daemon is running on windows
$ docker checkpoint ls --help
docker checkpoint ls is only supported on a Docker daemon running on linux, but the Docker daemon is running on windows
$ docker checkpoint rm --help
docker checkpoint rm is only supported on a Docker daemon running on linux, but the Docker daemon is running on windows
$ docker container start --checkpoint=foo mycontainer
"--checkpoint" requires the Docker daemon to run on linux, but the Docker daemon is running on windows
$ docker container start --checkpoint-dir=/foo/bar mycontainer
"--checkpoint-dir" requires the Docker daemon to run on linux, but the Docker daemon is running on windows

Add validation for stack names to prevent an empty name resulting in _all_
stacks to be returned after filtering, which can result in removal of services
for all stacks if `--prune`, or `docker stack rm` is used.
Before this change;
docker stack deploy -c docker-compose.yml one
docker stack deploy -c docker-compose.yml two
docker stack deploy -c docker-compose.yml three
docker stack deploy -c docker-compose.yml --prune ''
Removing service one_web
Removing service two_web
Removing service three_web
After this change:
docker stack deploy -c docker-compose.yml one
docker stack deploy -c docker-compose.yml two
docker stack deploy -c docker-compose.yml three
docker stack deploy -c docker-compose.yml --prune ''
invalid stack name: ""
Other stack commands were updated as well:
Before this change;
docker stack deploy -c docker-compose.yml ''
Creating network _default
failed to create network _default: Error response from daemon: rpc error: code = InvalidArgument desc = name must be valid as a DNS name component
docker stack ps ''
nothing found in stack:
docker stack rm ''
Removing service one_web
Removing service three_web
Removing service two_web
After this change:
docker stack deploy -c docker-compose.yml ''
invalid stack name: ""
docker stack ps ''
invalid stack name: ""
docker stack rm ''
invalid stack name: ""

- Don't wrap the code to be slightly more readable
- Rename `getServiceFilter()` to `getStackServiceFilter()` to be
consistent with other helper functions.

* Add "kubernetes" struct in config file with "allNamespaces" option, to opt-out this behavior when set as "disabled"

`docker stack services --filter=label=foo=bar --filter=label=foo=baz my-stack` with Swarm gets handled as `filter on (a label named foo with value bar) AND (a label named foo with value baz).
This obviously yields an empty result set every time, but if and how this should be changed is out of scope here, so simply align Kubernetes with Swarm for now.

Create a service with reservations and limits for memory and cpu:
docker service create --name test \
--limit-memory=100M --limit-cpu=1 \
--reserve-memory=100M --reserve-cpu=1 \
nginx:alpine
Verify the configuration
docker service inspect --format '{{json .Spec.TaskTemplate.Resources}}' test
{
"Limits": {
"NanoCPUs": 1000000000,
"MemoryBytes": 104857600
},
"Reservations": {
"NanoCPUs": 1000000000,
"MemoryBytes": 104857600
}
}
Update just CPU limit and reservation:
docker service update --limit-cpu=2 --reserve-cpu=2 test
Notice that the memory limit and reservation is not preserved:
docker service inspect --format '{{json .Spec.TaskTemplate.Resources}}' test
{
"Limits": {
"NanoCPUs": 2000000000
},
"Reservations": {
"NanoCPUs": 2000000000

}
Update just Memory limit and reservation:
docker service update --limit-memory=200M --reserve-memory=200M test
Notice that the CPU limit and reservation is not preserved:

This patch hides the [flags] in the usage output of commands, using the
new `.DisableFlagsInUseLine` option, instead of the temporary workaround
added in 8e600e10f7
Before this change:
docker run
"docker run" requires at least 1 argument.
See 'docker run --help'.
Usage: docker run [OPTIONS] IMAGE [COMMAND] [ARG...] [flags]
Run a command in a new container
