Hi. In a Docker Swarm cluster, nodes are usually in status=Ready:
ID HOSTNAME STATUS AVAILABILITY MANAGER STATUS 2kog6n57gopo8xc920lmxkr9v * moby Ready Active Leader
However, I’ve also seen nodes in status ‘Down’ and ‘Unknown’.
My questions are:
- Is there a list of possible node statuses? I’ve not found it in the official docs.
- Can I safely remove nodes in “Down” and “Unknown” status or are those nodes recoverable somehow?
