NAME

       podman-history - Show the history of an image

SYNOPSIS

       podman history [options] image[:tag|@digest]

       podman image history [options] image[:tag|@digest]

DESCRIPTION

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

       Valid placeholders for the Go template are listed below:

       ┌─────────────┬───────────────────────────────────────┐
