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