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
|
|
```
|
|
|
|
#### Membership
|
|
|
|
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
|
|

|
|
```
|
|
|
|
#### 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
|
|
