command: docker node ls
aliases: list
short: List nodes in the swarm
long: |-
  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

  ### 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](#id)
  * [label](#label)
  * [membership](#membership)
  * [name](#name)
  * [role](#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
