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
