List networks
Aliases:

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
$ 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:
$ docker network ls --no-trunc
NETWORK ID NAME DRIVER SCOPE
18a2866682b85619a026c81b98a5e375bd33e1b0936a26cc497c283d27bae9b3 none null local
c288470c46f6c8949c5f7e5099b5b7947b07eabe8d9a27d79a9cbf111adcbf47 host host local
7b369448dccbf865d397c8d2be0cda7cf7edc6b0945f77d2529912ae917a0185 bridge bridge local

Filtering
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>orlabel=<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:
$ 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.
$ 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:
$ 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.
$ 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.
$ 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.
$ 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:
$ 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:
$ 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:
$ 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:
$ 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:
$ 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.
Formatting
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:
$ docker network ls --format "{{.ID}}: {{.Driver}}"
afaaab448eb2: bridge
d1584f8dc718: host
391df270dc66: null
To list all networks in JSON format, use the json directive:
$ docker network ls --format json
