Sebastiaan van Stijn 3c244d1099 deprecate "--pause" flag on docker commit in favor of "--no-pause"
Commit [moby@17d870b] (API v1.13, docker v1.1.0) changed the default to pause
containers during commit, keeping the behavior opt-in for older API versions.
This version-gate was removed in [moby@1b1147e] because API versions lower
than v1.23 were no longer supported.

This patch deprecates the `--pause` flag in favor of a `--no-pause` flag to
be more explicit on the default. The old `--pause` flag is marked deprecated
but still functional. Using the deprecated flag will print a warning, and an
error is produced when trying to use both the old and new flag;

    docker commit --pause mycontainer
    Flag --pause has been deprecated, and enabled by default. Use --no-pause to disable pausing during commit.

    docker commit --pause=false mycontainer
    Flag --pause has been deprecated, and enabled by default. Use --no-pause to disable pausing during commit.

    docker commit --pause --no-pause mycontainer
    Flag --pause has been deprecated, use --no-pause instead
    conflicting options: --no-pause and --pause cannot be used together

commit

Create a new image from a container's changes

Aliases

docker container commit, docker commit

Options

Name Type Default Description
-a, --author string Author (e.g., John Hannibal Smith <hannibal@a-team.com>)
-c, --change list Apply Dockerfile instruction to the created image
-m, --message string Commit message
--no-pause bool Disable pausing container during commit

Description

It can be useful to commit a container's file changes or settings into a new image. This lets you debug a container by running an interactive shell, or export a working dataset to another server.

Commits do not include any data contained in mounted volumes.

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's created. Supported Dockerfile instructions: CMD|ENTRYPOINT|ENV|EXPOSE|LABEL|ONBUILD|USER|VOLUME|WORKDIR
