podman-commit - Create new image based on the changed container
podman commit [options] container image
podman commit
creates an image based on a changed container. The author of the
image can be set using the --author
flag. Various image instructions can be
configured with the --change
flag and a commit message can be set using the
--message
flag. The container and its processes are paused while the image is
committed. This minimizes the likelihood of data corruption when creating the new
image. If this is not desired, the --pause
flag can be set to false. When the commit
is complete, podman will print out the ID of the new image.
If image does not begin with a registry name component, localhost
will be added to the name.
--author, -a
Set the author for the committed image
--change, -c
Apply the following possible instructions to the created image: CMD | ENTRYPOINT | ENV | EXPOSE | LABEL | ONBUILD | STOPSIGNAL | USER | VOLUME | WORKDIR
Can be set multiple times
--format, -f
Set the format of the image manifest and metadata. The currently supported formats are oci and docker. If not specifically set, the default format used is oci.
--iidfile ImageIDfile
Write the image ID to the file.
--message, -m
Set commit message for committed image. The message field is not supported in oci format.
--pause, -p
Pause the container when creating an image
--quiet, -q
Suppress output
