1. Create a 3 Nodes Cluster ( 1 for master node and other 2 are for worker nodes)
2. Name these as master, worker01, worker02 nodes
3. On master node run the command docker swarm init
4. Copy the join command and run it on worker01 and worker02
5. Run docker node ls command on master node. It should show all the nodes in active state
6. Command docker swarm join-token worker will give token value for worker node
7 Command docker swarm join-token manager will give token value for manager node
8 Command docker info will give you swarm information as well like it is active or not
9. Command docker swarm leave will leave the node(worker node) from the cluster and docker info will return Swarm as inactive.
10. Command docker node rm worker01 will remove the worker from the list.
11 Command docker node rm -f worker02 will forcefully remove the worker from the list .
12 Command docker node inspect worker01 will inspect worker01 node.
13. Command docker node promote worker01 worker02 will promote worker01 and worker02 as manager node.
14. Command docker node demote worker01 worker02 will promote worker01 and worker02 as worker node.
