18 of the image can be set using the --author OPTION. Various image in‐
19 structions can be configured with the --change OPTION and a commit mes‐
20 sage can be set using the --message OPTION. The container and its pro‐
21 cesses aren't paused while the image is committed. If this is not de‐

23 plete, Podman prints out the ID of the new image.
