# node ls
```markdown
Usage: docker node ls [OPTIONS]
List nodes in the swarm
Aliases:
ls, list
Options:
-f, --filter value Filter output based on conditions provided
--help Print usage
-q, --quiet Only display IDs
```
## Description
Lists all the nodes that the Docker Swarm manager knows about. You can filter
using the `-f` or `--filter` flag. Refer to the [filtering](#filtering) section
for more information about available filter options.
## Examples
```bash
$ docker node ls
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
1bcef6utixb0l0ca7gxuivsj0 swarm-worker2 Ready Active
38ciaotwjuritcdtn9npbnkuz swarm-worker1 Ready Active
e216jshn25ckzbvmwlnh5jr3g * swarm-manager1 Ready Active Leader
```
### Filtering
The filtering flag (`-f` or `--filter`) format is of "key=value". If there is more
than one filter, then pass multiple flags (e.g., `--filter "foo=bar" --filter "bif=baz"`)
The currently supported filters are:
* [id](node_ls.md#id)
* [label](node_ls.md#label)
* [membership](node_ls.md#membership)
* [name](node_ls.md#name)
* [role](node_ls.md#role)
#### id
The `id` filter matches all or part of a node's id.
```bash
$ docker node ls -f id=1
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
1bcef6utixb0l0ca7gxuivsj0 swarm-worker2 Ready Active
```
#### label
The `label` filter matches nodes based on engine labels and on the presence of a `label` alone or a `label` and a value. Node labels are currently not used for filtering.
The following filter matches nodes with the `foo` label regardless of its value.
```bash
$ docker node ls -f "label=foo"
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
1bcef6utixb0l0ca7gxuivsj0 swarm-worker2 Ready Active
```
#### membersip
The `membership` filter matches nodes based on the presence of a `membership` and a value
`accepted` or `pending`.
The following filter matches nodes with the `membership` of `accepted`.
```bash
$ docker node ls -f "membership=accepted"
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
1bcef6utixb0l0ca7gxuivsj0 swarm-worker2 Ready Active
38ciaotwjuritcdtn9npbnkuz swarm-worker1 Ready Active
```
#### name
The `name` filter matches on all or part of a node hostname.
The following filter matches the nodes with a name equal to `swarm-master` string.
```bash
$ docker node ls -f name=swarm-manager1
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
e216jshn25ckzbvmwlnh5jr3g * swarm-manager1 Ready Active Leader
```
#### role
The `role` filter matches nodes based on the presence of a `role` and a value `worker` or `manager`.
The following filter matches nodes with the `manager` role.
```bash
$ docker node ls -f "role=manager"
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
e216jshn25ckzbvmwlnh5jr3g * swarm-manager1 Ready Active Leader
```
