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.
Alter the output for a format like 'json' or a Go template.
Valid placeholders for the Go template are listed below:
