2 Management Swarm

2.1 Exiting the cluster

[Email protected]:~$ docker swarm  Leave--Forcenode left the swarm.

#使用docker-machine switch environment to exit the cluster in Swarm-node1,swarn-master, the following only involves switching the environment does not provide code see 1.1

2.2 Swarm-master Building a cluster

[Email protected]:~$ docker swarm  initswarm initialized:current node (69NKAQU3IVFMTY5ISZ0UG0OIW) is now a manage R.to Add a worker to this swarm, run the following command:    join --token swmtkn-1192.168. 1.80:2377'Docker swarm Join-token manager' and follow the Instructions.

#同样token很重要, do not lose, Docker code hints are clear, join the cluster command is placed there

2.3 Swarm-node1 Join the cluster

 [email protected]:~$ docker swarm join --token swmtkn-1  -1qj2mfe14jw2tzhg1fxpqiyhxpnm4bqhrhae0dtpp6ip9og4s3-btyj7t5304eyeuhrl4dw1vx1l 192.168 . 1.80 : 2377   This node joined a swarm as a worker.
