# node ls

```markdown
Usage:  docker node ls [OPTIONS]

List nodes in the swarm

Aliases:
  ls, list

Options:
  -f, --filter filter   Filter output based on conditions provided
      --format string   Pretty-print nodes using a Go template
      --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.

> **Note**: This is a cluster management command, and must be executed on a swarm
> manager node. To learn about managers and workers, refer to the [Swarm mode
> section](https://docs.docker.com/engine/swarm/) in the documentation.

## 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
```
> **Note**:
> In the above example output, there is a hidden column of `.Self` that indicates if the
> node is the same node as the current docker daemon. A `*` (e.g., `e216jshn25ckzbvmwlnh5jr3g *`)
> means this node is the current docker daemon.


### 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
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
```

### Formatting

The formatting options (`--format`) pretty-prints nodes output
using a Go template.

Valid placeholders for the Go template are listed below:

Placeholder      | Description
-----------------|------------------------------------------------------------------------------------------
`.ID`            | Node ID
`.Self`          | Node of the daemon (`true/false`, `true`indicates that the node is the same as current docker daemon)
`.Hostname`      | Node hostname
`.Status`        | Node status
`.Availability`  | Node availability ("active", "pause", or "drain")
`.ManagerStatus` | Manager status of the node
`.TLSStatus`     | TLS status of the node ("Ready", or "Needs Rotation" has TLS certificate signed by an old CA)
`.EngineVersion` | Engine version

When using the `--format` option, the `node 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`, `Hostname`, and `TLS Status` entries separated by a colon for all nodes:

```bash
$ docker node ls --format "{{.ID}}: {{.Hostname}} {{.TLSStatus}}"
e216jshn25ckzbvmwlnh5jr3g: swarm-manager1 Ready
35o6tiywb700jesrt3dmllaza: swarm-worker1 Needs Rotation  
```
