初始化集群 Swarm
1. 使用 ssh 命令登录 manager 虚拟机：
PS C:\Users\Administrator> docker-machine ssh manager

使用命令：
docker swarm init --advertise-addr <MANAGER-IP>
docker@manager:~$ docker swarm init --advertise-addr 192.168.0.9
Swarm initialized: current node (j1kqy5hzlaljw9camxjufvxxo) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join \
--token SWMTKN-1-5p9gvdvpdagep4v6wea2lgfnzhzktsmvdzb3rh5h3zv0utyzza-22q2wamqy4ypd3glvzddczyto \
192.168.0.9:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
docker@manager:~$将 worker node 添加到集群 swarm
1. 登录到 worker 虚拟机
PS C:\Users\Administrator> docker-machine ssh worker

docker@worker:~$ docker swarm join \> --token SWMTKN-1-5p9gvdvpdagep4v6wea2lgfnzhzktsmvdzb3rh5h3zv0utyzza-22q2wa

docker swarm join-token worker
docker@manager:~$ docker swarm join-token worker
To add a worker to this swarm, run the following command: docker swarm join \
--token SWMTKN-1-5p9gvdvpdagep4v6wea2lgfnzhzktsmvdzb3rh5h3zv0utyzza-22q2wamqy4ypd3glvzddczyto \
192.168.0.9:2377
从而重新获得join命令

ssh 到 manager 虚拟机，并执行命令：
docker node ls
docker@manager:~$ docker node ls
