<!---MARKER_GEN_END-->

## Description

Lists all the networks the Engine `daemon` knows about. This includes the
networks that span across multiple hosts in a cluster.

## Examples

### List all networks

```console
$ docker network ls
NETWORK ID          NAME                DRIVER          SCOPE
7fca4eb8c647        bridge              bridge          local
9f904ee27bf5        none                null            local
cf03ee007fb4        host                host            local
78b03ee04fc4        multi-host          overlay         swarm
```

Use the `--no-trunc` option to display the full network id:

```console
$ docker network ls --no-trunc
NETWORK ID                                                         NAME                DRIVER           SCOPE
18a2866682b85619a026c81b98a5e375bd33e1b0936a26cc497c283d27bae9b3   none                null             local
c288470c46f6c8949c5f7e5099b5b7947b07eabe8d9a27d79a9cbf111adcbf47   host                host             local
7b369448dccbf865d397c8d2be0cda7cf7edc6b0945f77d2529912ae917a0185   bridge              bridge           local
95e74588f40db048e86320c6526440c504650a1ff3e9f7d60a497c4d2163e5bd   foo                 bridge           local
63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161   dev                 bridge           local
```

### <a name="filter"></a> Filtering (--filter)

The filtering flag (`-f` or `--filter`) format is a `key=value` pair. If there
is more than one filter, then pass multiple flags (e.g. `--filter "foo=bar" --filter "bif=baz"`).
Multiple filter flags are combined as an `OR` filter. For example,
`-f type=custom -f type=builtin` returns both `custom` and `builtin` networks.

The currently supported filters are:

* driver
* id (network's id)
* label (`label=<key>` or `label=<key>=<value>`)
* name (network's name)
* scope (`swarm|global|local`)
* type (`custom|builtin`)

#### Driver

The `driver` filter matches networks based on their driver.

The following example matches networks with the `bridge` driver:

```console
$ docker network ls --filter driver=bridge
NETWORK ID          NAME                DRIVER            SCOPE
db9db329f835        test1               bridge            local
f6e212da9dfd        test2               bridge            local
```

#### ID

The `id` filter matches on all or part of a network's ID.

The following filter matches all networks with an ID containing the
`63d1ff1f77b0...` string.

```console
$ docker network ls --filter id=63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161
NETWORK ID          NAME                DRIVER           SCOPE
63d1ff1f77b0        dev                 bridge           local
```

You can also filter for a substring in an ID as this shows:

```console
$ docker network ls --filter id=95e74588f40d
NETWORK ID          NAME                DRIVER          SCOPE
95e74588f40d        foo                 bridge          local

$ docker network ls --filter id=95e
NETWORK ID          NAME                DRIVER          SCOPE
95e74588f40d        foo                 bridge          local
```

#### Label

The `label` filter matches networks based on the presence of a `label` alone or a `label` and a
value.

The following filter matches networks with the `usage` label regardless of its value.

```console
$ docker network ls -f "label=usage"
NETWORK ID          NAME                DRIVER         SCOPE
db9db329f835        test1               bridge         local
f6e212da9dfd        test2               bridge         local
```

The following filter matches networks with the `usage` label with the `prod` value.

```console
$ docker network ls -f "label=usage=prod"
NETWORK ID          NAME                DRIVER        SCOPE
f6e212da9dfd        test2               bridge        local
```

#### Name

The `name` filter matches on all or part of a network's name.

The following filter matches all networks with a name containing the `foobar` string.

```console
$ docker network ls --filter name=foobar
NETWORK ID          NAME                DRIVER       SCOPE
06e7eef0a170        foobar              bridge       local
```

You can also filter for a substring in a name as this shows:

```console
$ docker network ls --filter name=foo
NETWORK ID          NAME                DRIVER       SCOPE
95e74588f40d        foo                 bridge       local
06e7eef0a170        foobar              bridge       local
```

#### Scope

The `scope` filter matches networks based on their scope.

The following example matches networks with the `swarm` scope:

```console
$ docker network ls --filter scope=swarm
NETWORK ID          NAME                DRIVER              SCOPE
xbtm0v4f1lfh        ingress             overlay             swarm
ic6r88twuu92        swarmnet            overlay             swarm
```

The following example matches networks with the `local` scope:

```console
$ docker network ls --filter scope=local
NETWORK ID          NAME                DRIVER              SCOPE
e85227439ac7        bridge              bridge              local
0ca0e19443ed        host                host                local
ca13cc149a36        localnet            bridge              local
f9e115d2de35        none                null                local
```

#### Type

The `type` filter supports two values; `builtin` displays predefined networks
(`bridge`, `none`, `host`), whereas `custom` displays user defined networks.

The following filter matches all user defined networks:

```console
$ docker network ls --filter type=custom
NETWORK ID          NAME                DRIVER       SCOPE
95e74588f40d        foo                 bridge       local
63d1ff1f77b0        dev                 bridge       local
```

By having this flag it allows for batch cleanup. For example, use this filter
to delete all user defined networks:

```console
$ docker network rm `docker network ls --filter type=custom -q`
```

A warning will be issued when trying to remove a network that has containers
attached.

### <a name="format"></a> Format the output (--format)

The formatting options (`--format`) pretty-prints networks output
using a Go template.

Valid placeholders for the Go template are listed below:

| Placeholder  | Description                                                                            |
|--------------|----------------------------------------------------------------------------------------|
| `.ID`        | Network ID                                                                             |
| `.Name`      | Network name                                                                           |
| `.Driver`    | Network driver                                                                         |
| `.Scope`     | Network scope (local, global)                                                          |
| `.IPv6`      | Whether IPv6 is enabled on the network or not.                                         |
| `.Internal`  | Whether the network is internal or not.                                                |
| `.Labels`    | All labels assigned to the network.                                                    |
| `.Label`     | Value of a specific label for this network. For example `{{.Label "project.version"}}` |
| `.CreatedAt` | Time when the network was created                                                      |

When using the `--format` option, the `network ls` command will either
output the data exactly as the template declares or, when using the
`table` directive, includes column headers as well.

The following example uses a template without headers and outputs the
`ID` and `Driver` entries separated by a colon (`:`) for all networks:

```console
$ docker network ls --format "{{.ID}}: {{.Driver}}"
afaaab448eb2: bridge
d1584f8dc718: host
391df270dc66: null
```

To list all networks in JSON format, use the `json` directive:

```console
$ docker network ls --format json
{"CreatedAt":"2021-03-09 21:41:29.798999529 +0000 UTC","Driver":"bridge","ID":"f33ba176dd8e","IPv6":"false","Internal":"false","Labels":"","Name":"bridge","Scope":"local"}
{"CreatedAt":"2021-03-09 21:41:29.772806592 +0000 UTC","Driver":"host","ID":"caf47bb3ac70","IPv6":"false","Internal":"false","Labels":"","Name":"host","Scope":"local"}
{"CreatedAt":"2021-03-09 21:41:29.752212603 +0000 UTC","Driver":"null","ID":"9d096c122066","IPv6":"false","Internal":"false","Labels":"","Name":"none","Scope":"local"}
```
