2 Initialise Swarm Mode[ | ]

host01
root@host01:~# docker swarm init
Swarm initialized: current node (75iwe1jhuv7vs4xklwyhrrshq) is now a manager.

To add a worker to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-4oc73j12c4b6iie5uerjn7c89d61oj3o81xiz6cojxcwhfkqne-0cwpe2fbjp8nl2hismo98xozx 172.17.0.11:2377

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
