implement docker push -a/--all-tags 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` Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

implement docker push -a/--all-tags 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` Signed-off-by: Sebastiaan van Stijn <github@gone.nl>
