|
||
## 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`, `2006-01-02T07:00`, 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
|
||
|
||
