$ 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.
