DESCRIPTION

17       podman  history displays the history of an image by printing out infor‐
18       mation about each layer used in the image. The information printed  out
19       for  each  layer include Created (time and date), Created By, Size, and
20       Comment. The output can be truncated or not using the --no-trunc  flag.
21       If  the  --human flag is set, the time of creation and size are printed
22       out in a human readable format.  The --quiet flag displays  the  ID  of
23       the  image only when set and the --format flag is used to print the in‐
24       formation using the Go template provided by the user.
