# network prune
<!---MARKER_GEN_START-->
Remove all unused networks
### Options
| Name | Type | Default | Description |
|:----------------------|:---------|:--------|:-------------------------------------------------|
| [`--filter`](#filter) | `filter` | | Provide filter values (e.g. `until=<timestamp>`) |
| `-f`, `--force` | | | Do not prompt for confirmation |
<!---MARKER_GEN_END-->
## Description
Remove all unused networks. Unused networks are those which are not referenced
by any containers.
## Examples
```console
$ docker network prune
WARNING! This will remove all custom networks not used by at least one container.
Are you sure you want to continue? [y/N] y
Deleted Networks:
n1
n2
```
### <a name="filter"></a> Filtering (--filter)
The filtering flag (`--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:
* until (`<timestamp>`) - only remove networks created before given timestamp
* 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.
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 networks with the specified labels. The other
format is the `label!=...` (`label!=<key>` or `label!=<key>=<value>`), which removes
networks without the specified labels.
The following removes networks created more than 5 minutes ago. Note that
system networks such as `bridge`, `host`, and `none` will never be pruned:
```console
$ docker network ls
NETWORK ID NAME DRIVER SCOPE
7430df902d7a bridge bridge local
ea92373fd499 foo-1-day-ago bridge local
ab53663ed3c7 foo-1-min-ago bridge local
97b91972bc3b host host local
f949d337b1f5 none null local
$ docker network prune --force --filter until=5m
Deleted Networks:
foo-1-day-ago
$ docker network ls
NETWORK ID NAME DRIVER SCOPE
7430df902d7a bridge bridge local
ab53663ed3c7 foo-1-min-ago bridge local
97b91972bc3b host host local
f949d337b1f5 none null local
```
