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

       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 dockerps and then running:

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

       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 dockerps 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.

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