# commit
|
|
|
|
Usage: docker commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]
|
|
|
|
Create a new image from a container's changes
|
|
|
|
-a, --author="" Author (e.g., "John Hannibal Smith <hannibal@a-team.com>")
|
|
-c, --change=[] Apply specified Dockerfile instructions while committing the image
|
|
--help=false Print usage
|
|
-m, --message="" Commit message
|
|
-p, --pause=true Pause container during commit
|
|
|
|
It can be useful to commit a container's file changes or settings into a new
|
|
image. This allows you debug a container by running an interactive shell, or to
|
|
export a working dataset to another server. Generally, it is better to use
|
|
Dockerfiles to manage your images in a documented and maintainable way.
|
|
|
|
The commit operation will not include any data contained in
|
|
volumes mounted inside the container.
|
|
|
|
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 'p' option to false.
|
|
|
|
The `--change` option will apply `Dockerfile` instructions to the image that is
|
|
created. Supported `Dockerfile` instructions:
|
|
`CMD`|`ENTRYPOINT`|`ENV`|`EXPOSE`|`LABEL`|`ONBUILD`|`USER`|`VOLUME`|`WORKDIR`
|
