Node swarm-node-02 removed from swarm
Attempt to remove a running node from a swarm
Removes the specified nodes from the swarm, but only if the nodes are in the down state. If you attempt to remove an active node you will receive an error:
$ docker node rm swarm-node-03 Error response from daemon: rpc error: code = 9 desc = node swarm-node-03 is not down and can't be removed
Forcibly remove an inaccessible node from a swarm
If you lose access to a worker node or need to shut it down because it has been compromised or is not behaving as expected, you can use the --force option. This may cause transient errors or interruptions, depending on the type of task being run on the node.
$ docker node rm --force swarm-node-03
Node swarm-node-03 removed from swarm
A manager node must be demoted to a worker node (using docker node demote) before you can remove it from the swarm.
