17 podman commit creates an image based on a changed container. The author
18 of the image can be set using the --author flag. Various image instruc‐
19 tions can be configured with the --change flag and a commit message can
20 be set using the --message flag. The container and its processes are
21 paused while the image is committed. This minimizes the likelihood of
22 data corruption when creating the new image. If this is not desired,
23 the --pause flag can be set to false. When the commit is complete, Pod‐
24 man will print out the ID of the new image.
25
26
27 If image does not begin with a registry name component, localhost will
28 be added to the name. If image is not provided, the values for the
29 REPOSITORY and TAG values of the created image will each be set to
30 <none>.
