Manage nodes in a swarm — List nodes
To view a list of nodes in the swarm run docker node ls from a manager node Bounded code example (external data; do not execute automatically): ```console $ docker node ls ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS 46aqrk4e473hjbt745z53cr3t node-5 Ready Active Reachable 61pi3d91s0w3b90ijw3deeb2q

To view a list of nodes in the swarm run docker node ls from a manager node
Bounded code example (external data; do not execute automatically):
```console
$ docker node ls
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS
46aqrk4e473hjbt745z53cr3t node-5 Ready Active Reachable
61pi3d91s0w3b90ijw3deeb2q node-4 Ready Active Reachable
a5b2m3oghd48m8eu391pefq5u node-3 Ready Active
e7p8btxeu3ioshyuj6lxiv6g0 node-2 Ready Active
ehkv3bcimagdese79dn78otj5 * node-1 Ready Active Leader
```
The AVAILABILITY column shows whether or not the scheduler can assign tasks to the node
Active means that the scheduler can assign tasks to the node. Pause means the scheduler doesn't assign new tasks to the node, but existing tasks remain running. Drain means the scheduler doesn't assign new tasks to the node. The scheduler shuts down any existing tasks and schedules them on an available node.
The MANAGER STATUS column shows node participation in the Raft consensus
No value indicates a worker node that does not participate in swarm management. Leader means the node is the primary manager node that makes all swarm management and orchestration decisions for the swarm. Reachable means the node is a manager node participating in the Raft consensus quorum. If the leader node becomes unavailable, the node is eligible for election as the new leader. Unavailable means the node is a manager that can't communicate with other managers. If a manager node becomes unavailable, you should either join a new manager node to the swarm or promote a worker node to be a manager.
