NAME
podman-volume-prune - Remove all unused volumes
SYNOPSIS
podman volume prune [options]
DESCRIPTION
Removes unused volumes. By default all unused volumes are removed, the --filter flag can be used to filter specific volumes. Users are prompted to confirm the removal of all the unused volumes. To bypass the confirmation, use the --force flag.
OPTIONS
--filter
Provide filter values.
The filters argument format is of key=value. If there is more than one filter, then pass multiple OPTIONS: --filter foo=bar --filter bif=baz.
Supported filters:
| Filter | Description | 
|---|---|
| dangling | [Bool] Only remove volumes not referenced by any containers | 
| driver | [String] Only remove volumes with the given driver | 
| label | [String] Only remove volumes, with (or without, in the case of label!=[...] is used) the specified labels. | 
| name | [String] Only remove volume with the given name | 
| opt | [String] Only remove volumes created with the given options | 
| scope | [String] Only remove volumes with the given scope | 
| 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.
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.
