podman-history(1) General Commands Manual podman-history(1) 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 read- able 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 tem- plate 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: +---------------+-----------------------------+ | Placeholder | Description | +---------------+-----------------------------+ | .Comment | Comment for the layer | +---------------+-----------------------------+ | .Created | if --human, time elapsed | | | since creation, otherwise | | | time stamp of creation | +---------------+-----------------------------+ | .CreatedAt | Time when the image layer | | | was created | +---------------+-----------------------------+ | .CreatedBy | Command used to create the | | | layer | +---------------+-----------------------------+ | .CreatedSince | Elapsed time since the im- | | | age layer was created | +---------------+-----------------------------+ | .ID | Image ID | +---------------+-----------------------------+ | .Size | Size of layer on disk | +---------------+-----------------------------+ | .Tags | Image tags | +---------------+-----------------------------+ --help, -h Print usage statement --human, -H Display sizes and dates in human readable format (default true). --no-trunc Do not truncate the output (default false). --quiet, -q Print the numeric IDs only (default false).
