NAMEpodman-commit - Create new image based on the changed container
SYNOPSISpodman commit [options] container [image] podman container commit [options] container [image]
DESCRIPTIONpodman commit creates an image based on a changed container. The author of the image can be set using the --author OPTION. Various image instructions can be configured with the --change OPTION and a commit message can be set using the --message OPTION. 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 OPTION 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>.
OPTIONS

--include-volumesInclude in the committed image any volumes added to the container by the --volume or --mount OPTIONS to the podman create and podman run commands.
The default is false.
--message, -m=messageSet commit message for committed image.
