This add a new filter to 'docker network ls' to allow filtering by driver-name. Contrary to "ID" and "name" filters, this filter only supports an *exact* match. Signed-off-by: Sebastiaan van Stijn <github@gone.nl>

# NAME
|
|
docker-network-ls - list networks
|
|
|
|
# SYNOPSIS
|
|
**docker network ls**
|
|
[**-f**|**--filter**[=*[]*]]
|
|
[**--no-trunc**[=*true*|*false*]]
|
|
[**-q**|**--quiet**[=*true*|*false*]]
|
|
[**--help**]
|
|
|
|
# DESCRIPTION
|
|
|
|
Lists all the networks the Engine `daemon` knows about. This includes the
|
|
networks that span across multiple hosts in a cluster, for example:
|
|
|
|
```bash
|
|
$ docker network ls
|
|
NETWORK ID NAME DRIVER
|
|
7fca4eb8c647 bridge bridge
|
|
9f904ee27bf5 none null
|
|
cf03ee007fb4 host host
|
|
78b03ee04fc4 multi-host overlay
|
|
```
|
|
|
|
Use the `--no-trunc` option to display the full network id:
|
|
|
|
```bash
|
|
$ docker network ls --no-trunc
|
|
NETWORK ID NAME DRIVER
|
|
18a2866682b85619a026c81b98a5e375bd33e1b0936a26cc497c283d27bae9b3 none null
|
|

|
|

```
|
|
|
|
## 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)
|
|
* type (custom|builtin)
|
|
|
|
#### Driver
|
|
|
|
The `driver` filter matches networks based on their driver.
|
|
|
|
The following example matches networks with the `bridge` driver:
|
|
|
|
```bash
|
|
$ docker network ls --filter driver=bridge
|
|
NETWORK ID NAME DRIVER
|
|
db9db329f835 test1 bridge
|
|
f6e212da9dfd test2 bridge
|
|
```
|
|
|
|
#### 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.
|
|
|
|
```bash
|
|
$ docker network ls --filter id=63d1ff1f77b07ca51070a8c227e962238358bd310bde1529cf62e6c307ade161
|
|
NETWORK ID NAME DRIVER
|
|
63d1ff1f77b0 dev bridge
|
|
```
|
|
|
|
You can also filter for a substring in an ID as this shows:
|
|
|
|
```bash
|
|
$ docker network ls --filter id=95e74588f40d
|
|
NETWORK ID NAME DRIVER
|
|
95e74588f40d foo bridge
|
|
|
|
$ docker network ls --filter id=95e
|
|
NETWORK ID NAME DRIVER
|
|
95e74588f40d foo bridge
|
|
```
|
|
|
|
#### 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.
|
|
|
|
```bash
|
|
$ docker network ls -f "label=usage"
|
|
NETWORK ID NAME DRIVER
|
|
db9db329f835 test1 bridge
|
|
f6e212da9dfd test2 bridge
|
|
```
|
|
|
|
The following filter matches networks with the `usage` label with the `prod` value.
|
|
|
|
```bash
|
|
$ docker network ls -f "label=usage=prod"
|
|
NETWORK ID NAME DRIVER
|
|
f6e212da9dfd test2 bridge
|
|
```
|
|
|
|
#### 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.
|
|
|
|
```bash
|
|
$ docker network ls --filter name=foobar
|
|
NETWORK ID NAME DRIVER
|
|
06e7eef0a170 foobar bridge
|
|
```
|
|
|
|
You can also filter for a substring in a name as this shows:
|
|
|
|
```bash
|
|
$ docker network ls --filter name=foo
|
|
NETWORK ID NAME DRIVER
|
|
95e74588f40d foo bridge
|
|
06e7eef0a170 foobar bridge
|
|
```
|
|
|
|
#### 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:
|
|
|
|
```bash
|
|
$ docker network ls --filter type=custom
|
|
NETWORK ID NAME DRIVER
|
|
95e74588f40d foo bridge
|
|
63d1ff1f77b0 dev bridge
|
|
```
|
|
|
|
By having this flag it allows for batch cleanup. For example, use this filter
|
|
to delete all user defined networks:
|
|
|
|
```bash
|
|
$ 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.
