Usage: docker system prune [OPTIONS] Delete unused data Options: -a, --all Remove all unused images not just dangling ones --filter filter Provide filter values (e.g. 'until=<timestamp>') -f, --force Do not prompt for confirmation --help Print usage
Remove all unused containers, volumes, networks and images (both dangling and unreferenced).
$ docker system prune -a WARNING! This will remove: - all stopped containers - all volumes not used by at least one container - all networks not used by at least one container - all images without at least one container associated to them Are you sure you want to continue?

The filtering flag (-f
or --filter
) format is of “key=value”. If there is more than one filter, then pass multiple flags (e.g., --filter "foo=bar" --filter "bif=baz"
)
The currently supported filters are:
<timestamp>
) - only remove containers, images, and networks created before given timestamplabel=<key>
, label=<key>=<value>
, label!=<key>
, or label!=<key>=<value>
) - only remove containers, images, networks, and volumes with (or without, in case label!=...
is used) 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 daemon machine’s time. Supported formats for date formatted time stamps include RFC3339Nano, RFC3339, 2006-01-02T15:04:05
, 2006-01-02T15:04:05.999999999
, 2006-01-02Z07:00
, and 2006-01-02
. The local timezone on the daemon will be used if you do not provide either a Z
or a +-00:00
timezone offset at the end of the timestamp. When providing Unix timestamps enter seconds[.nanoseconds], where seconds is the number of seconds that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a fraction of a second no more than nine digits long.
The label
filter accepts two formats. One is the label=...
(label=<key>
or label=<key>=<value>
), which removes containers, images, networks, and volumes with the specified labels. The other format is the label!=...
(label!=<key>
or label!=<key>=<value>
), which removes containers, images, networks, and volumes without the specified labels.
