DESCRIPTION

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

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

EXAMPLES

Creating a new image from an existing container
56       An existing Fedora based container has had Apache installed while
57       running in interactive mode with the bash shell. Apache is also
58       running. To create a new image run docker ps to find the container's ID
59       and then run:
60
61
62              # docker commit -m="Added Apache to Fedora base image" \
63                -a="A D Ministrator" 98bd7fc99854 fedora/fedora_httpd:20
64
65
66
67       Note that only a-z0-9-_. are allowed when naming images from an
68       existing container.
69
70

Apply specified Dockerfile instructions while committing the image
72       If an existing container was created without the DEBUG environment
73       variable set to "true", you can create a new image based on that
74       container by first getting the container's ID with docker ps and then
75       running:
76
77
78              # docker commit -c="ENV DEBUG true" 98bd7fc99854 debug-image
