NAME

kpod-history - Shows the history of an image

SYNOPSIS

kpod history IMAGE[:TAG|DIGEST] [--human|-H] [--no-trunc] [--quiet|-q] [--format] [--help|-h]

DESCRIPTION

kpod 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:

Placeholder Description
.ID Image ID
.Created if --human, time elapsed since creation, otherwise time stamp of creation
.CreatedBy Command used to create the layer
.Size Size of layer on disk
.Comment Comment for the layer
