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

$ 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)

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 95e74588f40db048e86320c6526440c504650a1ff3e9f7d60a497c4d2163e5bd foo bridge local 63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161 dev bridge local

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.

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:

$ 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 {"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"}
