NAME

podman-volume-prune - Remove unused volumes

SYNOPSIS

podman volume prune [options]

DESCRIPTION

Remove unused volumes. By default only anonymous (unnamed) unused volumes are removed. Anonymous volumes are those created with a container (e.g. podman run -v /path without a volume name). Use --all (or -a) to remove all unused volumes, including named ones.

The --filter flag can be used to restrict which volumes are considered. Users are prompted to confirm removal unless --force is used.

OPTIONS

--all, -a

Remove all unused volumes (anonymous and named). Without this option, only anonymous unused volumes are removed.

--dry-run

Show which volumes would be pruned without removing them.

--filter

Provide filter values.

If there is more than one filter, the --filter option should be passed multiple times: --filter label=test --filter until=10m.

Filters with the same key work inclusive, with the only exception being label which is exclusive. Filters with different keys always work exclusive.

Supported filters:

Filter	Description
all	[Bool] When true, remove all unused volumes (same as --all). When false or unset, only anonymous volumes are considered.
anonymous	[Bool] Only remove volumes that are anonymous (true) or named (false).
label	[String] Only remove volumes, with (or without, in the case of label!=[…] is used) the specified labels.
label!	[String] Only remove volumes without the specified labels.
until	[DateTime] Only remove volumes created before given timestamp.
after/since	[Volume] Filter by volumes created after the given VOLUME (name or tag)

The label filter accepts two formats. One is the label=key or label=key=value, which removes volumes with the specified labels. The other format is the label!=key or label!=key=value, which removes volumes without the specified labels.

NOTE: label! filters are combined with AND, so that the behavior is consistent with label, while in Docker, they are combined with OR.

The until filter can be Unix timestamps, date formatted timestamps, or Go duration strings (e.g. 10m, 1h30m) computed relative to the machine’s time.

--force, -f

Do not prompt for confirmation.

EXAMPLES

Prune only anonymous unused volumes (default).

$ podman volume prune

Prune only anonymous unused volumes without confirmation.

$ podman volume prune --force

Prune all unused volumes (anonymous and named).

$ podman volume prune --all --force

Prune all unused volumes using the filter (equivalent to --all).

$ podman volume prune --filter all=true --force

Prune unused volumes that have the specified label.

$ podman volume prune --filter label=mylabel=mylabelvalue

Prune unused volumes that do NOT have a specific label key/value:

$ podman volume prune --filter label!=mylabel=mylabelvalue

Prune unused volumes that have a specific label key (regardless of value):

$ podman volume prune --filter label=environment

Prune unused volumes that do NOT have a specific label key:

$ podman volume prune --filter label!=environment

Preview all unused volumes without removing them.

$ podman volume prune --all --dry-run
