DOCKER(1)                                                            DOCKER(1)

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

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

DESCRIPTION
       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.

EXAMPLES
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

OPTIONS
       -a, --author=""
           Author (e.g., "John Hannibal Smith <hannibal@a-team.com>")

       -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
