NAME

podman-system-prune - Remove all unused container, image and volume data

SYNOPSIS

podman system prune [-all|--a] [-force|--f] [-help|--h] [-volumes|--v]

DESCRIPTION

podman system prune removes all unused containers, (both dangling and unreferenced) from local storage and optionally, volumes.

With the all option, you can delete all unused images. Unused images are dangling images as well as any image that does not have any containers based on it.

By default, volumes are not removed to prevent important data from being deleted if there is currently no container using the volume. Use the --volumes flag when running the command to prune volumes as well.

OPTIONS

--all, -a

Remove all unused images not just dangling ones.

--force, -f

Do not prompt for confirmation

--volumes

Prune volumes not used by at least one container
