podman-commit(1)

NAME

podman-commit - Create new image based on the changed container

SYNOPSIS

podman commit [options] container image

DESCRIPTION

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.

OPTIONS

--author, -a=author

Set the author for the committed image

--change, -c=instruction

--format, -f=format

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.

--include-volumes

Include in the committed image any volumes added to the container by the --volume or --mount options to the podman create and podman run commands.

--message, -m=message

Set commit message for committed image. The message field is not supported in oci format.

--pause, -p

Pause the container when creating an image
