Show podman disk usage

Description

Show podman disk usage for images, containers and volumes.

Note: The RECLAIMABLE size that is reported for images can be incorrect. It might report that it can reclaim more than a prune would actually free. This will happen if you are using different images that share some layers.

Options

--format=format

Pretty-print images using a Go template or JSON. This flag is not allowed in combination with --verbose

Valid placeholders for the Go template are listed below:

Placeholder	Description
.Active	Indicates whether volume is in use
.RawReclaimable	Raw reclaimable size of each Type
.RawSize	Raw size of each type
.Reclaimable	Reclaimable size or each type (human-readable)
.Size	Size of each type (human-readable)
.Total	Total items for each type
.Type	Type of data

--verbose, -v
