Cobra allows for aliases to be defined for a command, but only allows these
to be defined at the same level (for example, `docker image ls` as alias for
`docker image list`). Our CLI has some commands that are available both as a
top-level shorthand as well as `docker <object> <verb>` subcommands. For example,
`docker ps` is a shorthand for `docker container ps` / `docker container ls`.
This patch introduces a custom "aliases" annotation that can be used to print
all available aliases for a command. While this requires these aliases to be
defined manually, in practice the list of aliases rarely changes, so maintenance
should be minimal.
As a convention, we could consider the first command in this list to be the
canonical command, so that we can use this information to add redirects in
our documentation in future.
Before this patch:
docker images --help
Usage: docker images [OPTIONS] [REPOSITORY[:TAG]]
List images
Options:
-a, --all Show all images (default hides intermediate images)
...
With this patch:
docker images --help
Usage: docker images [OPTIONS] [REPOSITORY[:TAG]]
List images
Aliases:
docker image ls, docker image list, docker images
Options:
-a, --all Show all images (default hides intermediate images)

the option.

This replaces the use of bash where suitable, to allow easier copy/pasting
of shell examples without copying the prompt or process output.

these markdown files are not consumed directly in the docs,
but only their content is included through the YAML does,
so there's no need to have these comments in them
Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
If the markdown contains trailing spaces, or has tabs included,
the YAML generator uses a compact format for the text (using `\n`
and `\t`, instead of plain newlines).
The compact format makes it difficult to review changes in the
yaml docs when vendoring in the documentation repository.
This patch:
- removes trailing whitespace
- replaces tabs for spaces
- fixes some minor formatting and markdown issues

The `docker push` command up until [v0.9.1](https://github.com/moby/moby/blob/v0.9.1/api/client.go#L998)
always pushed all tags of a given image, so `docker push foo/bar` would push (e.g.)
all of `foo/bar:latest`, `foo:/bar:v1`, `foo/bar:v1.0.0`.
Pushing all tags of an image was not desirable in many case, so docker v0.10.0
enhanced `docker push` to optionally specify a tag to push (`docker push foo/bar:v1`)
(see https://github.com/moby/moby/issues/3411 and the pull request that implemented
this: https://github.com/moby/moby/pull/4948).
This behavior exists up until today, and is confusing, because unlike other commands,
`docker push` does not default to use the `:latest` tag when omitted, but instead
makes it push "all tags of the image"
For example, in the following situation;
```
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
thajeztah/myimage latest b534869c81f0 41 hours ago 1.22MB
```
Running `docker push thajeztah/myimage` seemingly does the expected behavior (it
pushes `thajeztah/myimage:latest` to Docker Hub), however, it does not so for the
reason expected (`:latest` being the default tag), but because `:latest` happens
to be the only tag present for the `thajeztah/myimage` image.
If another tag exists for the image:
```
docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
thajeztah/myimage latest b534869c81f0 41 hours ago 1.22MB
thajeztah/myimage v1.0.0 b534869c81f0 41 hours ago 1.22MB
```
Running the same command (`docker push thajeztah/myimage`) will push _both_ images
to Docker Hub.
> Note that the behavior described above is currently not (clearly) documented;
> the `docker push` reference documentation (https://docs.docker.com/engine/reference/commandline/push/)
does not mention that omitting the tag will push all tags
This patch changes the default behavior, and if no tag is specified, `:latest` is
assumed. To push _all_ tags, a new flag (`-a` / `--all-tags`) is added, similar
to the flag that's present on `docker pull`.
With this change:
- `docker push myname/myimage` will be the equivalent of `docker push myname/myimage:latest`
- to push all images, the user needs to set a flag (`--all-tags`), so `docker push --all-tags myname/myimage:latest`

Commit ed13c3abfb242905ec012e8255dc6f26dcf122f6 added flags
for Docker Content Trust. Depending on the `verify` boolean,
the message is "Skip image verification", or "Skip image signing".
"Signing" is intended for `docker push` / `docker plugin push`.
During the migration to Cobra, this boolean got flipped for
`docker push` (9640e3a4514f96a890310757a09fd77a3c70e931),
causing `docker push` to show the incorrect flag description.
This patch changes the flags to use the correct description
for `docker push`, and `docker plugin push`.
To prevent this confusion in future, the boolean argument
is removed, and a `AddTrustSigningFlags()` function is added.

It was suggested to me that documentation for "docker pull" and "docker
push" should reference "docker login", to make clearer how to specify
credentials for a push or pull operation. Add a note to the manual pages
and reference documentation explaining how registry credentials are
managed.
