Chapter 14.4 - Simulate Docker Node1 Failure - After leaving swarm, cannot do "docker node update" or "docker node ls" #58

Exercise Chapter 14.4 - Try It Now - Simulate Node1 Failure - page 267

Problem On node2 (or any node for that matter), i cannot execute successfully: docker node update --availability active node5

I also cannot do docker node ls on any of the five nodes. So essentially, I have no idea who is the Leader anymore or can tell who is. Seems like a pretty straight forward exercise. Have the docker rules changed now?

Resolved the issue. There was none. Did not join node2 and 3 as managers originally.
