16## Description
17
18Remove all unused networks. Unused networks are those which are not referenced
19by any containers.
20
21## Examples
22
23```console
24$ docker network prune
25
26WARNING! This will remove all custom networks not used by at least one container.
27Are you sure you want to continue? [y/N] y

33### <a name="filter"></a> Filtering (--filter)
34
35The filtering flag (`--filter`) format is of "key=value". If there is more
36than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
37
38The currently supported filters are:
39
40* until (`<timestamp>`) - only remove networks created before given timestamp
41* label (`label=<key>`, `label=<key>=<value>`, `label!=<key>`, or `label!=<key>=<value>`) - only remove networks with (or without, in case `label!=...` is used) the specified labels.
42
43The `until` filter can be Unix timestamps, date formatted
44timestamps, or Go duration strings (e.g. `10m`, `1h30m`) computed
45relative to the daemon machine’s time. Supported formats for date
46formatted time stamps include RFC3339Nano, RFC3339, `2006-01-02T15:04:05`,
47`2006-01-02T15:04:05.999999999`, `2006-01-02Z07:00`, and `2006-01-02`. The local
48timezone on the daemon will be used if you do not provide either a `Z` or a
49`+-00:00` timezone offset at the end of the timestamp. When providing Unix
50timestamps enter seconds[.nanoseconds], where seconds is the number of seconds
51that have elapsed since January 1, 1970 (midnight UTC/GMT), not counting leap
52seconds (aka Unix epoch or Unix time), and the optional .nanoseconds field is a
53fraction of a second no more than nine digits long.
54
55The `label` filter accepts two formats. One is the `label=...` (`label=<key>` or `label=<key>=<value>`),
56which removes networks with the specified labels. The other
57format is the `label!=...` (`label!=<key>` or `label!=<key>=<value>`), which removes
58networks without the specified labels.
59
60The following removes networks created more than 5 minutes ago. Note that
61system networks such as `bridge`, `host`, and `none` will never be pruned:
62
63```console
64$ docker network ls

66NETWORK ID NAME DRIVER SCOPE
677430df902d7a bridge bridge local
68ea92373fd499 foo-1-day-ago bridge local

73$ docker network prune --force --filter until=5m
