       docker-container-commit - Create a new image from a container's changes


       docker container commit [OPTIONS] CONTAINER [REPOSITORY[:TAG]]


       Create a new image from an existing container specified by name or container ID.  The new
       image will contain the contents of the container filesystem, excluding any data volumes.
       Refer to docker-tag(1) for more information about valid image and tag names.

       While the docker commit command is a convenient way of extending an existing image, you
       should prefer the use of a Dockerfile and docker build for generating images that you
       intend to share with other people.


Creating a new image from an existing container

       An existing Fedora based container has had Apache installed while running in interactive
       mode with the bash shell. Apache is also running. To create a new image run docker ps to
       find the container's ID and then run:

              $ docker commit -m="Added Apache to Fedora base image" \
                -a="A D Ministrator" 98bd7fc99854 fedora/fedora_httpd:20

       Note that only a-z0-9-_. are allowed when naming images from an existing container.

Apply specified Dockerfile instructions while committing the image

       If an existing container was created without the DEBUG environment variable set to "true",
       you can create a new image based on that container by first getting the container's ID
       with docker ps and then running:

              $ docker container commit -c="ENV DEBUG true" 98bd7fc99854 debug-image


       -a, --author=""
           Author (e.g., "John Hannibal Smith ⟨⟩")

       -c, --change=
           Apply Dockerfile instruction to the created image

       -h, --help[=false]
           help for commit

       -m, --message=""
           Commit message

       -p, --pause[=true]
           Pause container during commit
