# docker network prune

**Description:** Remove all unused networks

**Usage:** `docker network prune [OPTIONS]`










## Description

Remove all unused networks. Unused networks are those which are not referenced
by any containers.


## Options

| Option | Default | Description |
|--------|---------|-------------|
| `--filter` |  |  Provide filter values (e.g. `until=<timestamp>`) |
| `-f`, `--force` |  |  Do not prompt for confirmation |



## 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
```

### Filtering (--filter) {#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"`).

When multiple filters are provided, they are combined as follows:

- Multiple filters with **different keys** are combined using AND logic.
  A network must satisfy all filter conditions to be pruned.
- Multiple filters with the **same key** are combined using OR logic.
  A network is pruned if it matches any of the values for that key.

For example, `--filter "label=foo" --filter "until=24h"` prunes networks
that have the `foo` label **and** were created more than 24 hours ago.
Conversely, `--filter "label=foo" --filter "label=bar"` prunes networks
that have **either** the `foo` **or** `bar` label.

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 supported by [ParseDuration](https://pkg.go.dev/time#ParseDuration) (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
