Error response from daemon: This node is already part of a swarm. Use "docker swarm leave" to leave this swarm and join another one.
[root@master mydocker]# docker swarm leave
Error response from daemon: You are attempting to leave the swarm on a node that is participating as a manager. Removing the last manager erases all current state of the swarm. Use `--force` to ignore this message.
[root@master mydocker]# docker swarm leave --force
Node left the swarm.
[root@master mydocker]# docker swarm init --advertise-addr 192.168.252.101
Swarm initialized: current node (uuizcn0sunpkntstvr1w2jyjv) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-610n3pl0k7e35w6t04udmgry7muap47jznqvouu0ffm3ykzedd-aki3ch2y825j5aj80v4q8yfyu 192.168.252.101:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
