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

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