podman image history [options] image[:tag|@digest]
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:
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 |
--human, -H=true|false
Display sizes and dates in human readable format (default true).
--no-trunc=true|false
Do not truncate the output (default false).
--notruncate
Do not truncate the output
--quiet, -q=true|false
Print the numeric IDs only (default false). --format=format
Alter the output for a format like 'json' or a Go template.
