Examples

List all networks

$ sudo 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

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> 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:

$ 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
