podman-commit - Create new image based on the changed container
podman commit [options] container [image]
podman container 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. If image is not provided, the values for the REPOSITORY and TAG values of the created image will each be set to <none>.
Set the author for the committed image
Apply the following possible instructions to the created image: CMD | ENTRYPOINT | ENV | EXPOSE | LABEL | ONBUILD | STOPSIGNAL | USER | VOLUME | WORKDIR
Can be set multiple times
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.
Write the image ID to the file.
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.
Set commit message for committed image. The message field is not supported in oci format.
Pause the container when creating an image
