Dear Instructor,
In the video of “Swarm setup 2 node cluster”, there is a mistake
"docker node ls " you are mentioning it can run in any node, p
but in real you cannot, you can run "docker node ls " only from the manager and not from the nodes
pasting the command and its out put which I got when trying out in nodes
itsupport@node-c:~$ docker node ls
Error response from daemon: This node is not a swarm manager. Worker nodes can’t be used to view or modify cluster state. Please run this command on a manager node or promote the current node to a manager
