# docker network ls
**Description:** List networks
**Usage:** `docker network ls [OPTIONS]`
**Aliases:** `docker network list`
## Description
Lists all the networks the Engine `daemon` knows about. This includes the
networks that span across multiple hosts in a cluster.
## Options
| Option | Default | Description |
|--------|---------|-------------|
| `-f`, `--filter` | | Provide filter values (e.g. `driver=bridge`) |
| `--format` | | Format output using a custom template:
'table': Print output in table format with column headers (default)
'table TEMPLATE': Print output in table format using the given Go template
'json': Print in JSON format
'TEMPLATE': Print output using the given Go template.
Refer to https://docs.docker.com/go/formatting/ for more information about formatting output with templates |
| `--no-trunc` | | Do not truncate the output |
| `-q`, `--quiet` | | Only display network IDs |
## 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
```
### List networks without truncating the ID column (--no-trun) {#no-trunc}
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
```
### Filtering (--filter) {#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=` or `label==`)
* 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.
### Format the output (--format) {#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"}
```
