Docker Swarm 入门示例1: 创建swarm

1. 打开manager1服务器 shell ssh to swarm-master

   docker-machine ssh swarm-master # 如果使用docker-machine
   

2. 初始化 swarm docker swarm init docker swarm init --advertise-addr <MANAGER-IP>

   
   $ docker swarm init --advertise-addr 192.168.10.211
   
   Swarm initialized: current node (j1dxu07y1b7z0x5t0xbznbqra) is now a manager.
   
   To add a worker to this swarm, run the following command:
   
       docker swarm join --token SWMTKN-1-1kmmb9epxw85f29ucb5gfd9638u0yzdrbmsl7zjcgy3yovut18-bybi5arfvjsvv99nwh6pzltpw 192.168.10.211:2377
   
   To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
   

3. 查看swarm 信息 docker info

   $ docker info
   Containers: 2
   Running: 0
   Paused: 0
   Stopped: 2
     ...snip...
   Swarm: active <--------------
     NodeID: dxn1zf6l61qsb1josjja83ngz
     Is Manager: true
     Managers: 1
     Nodes: 1
     ...snip...
   

4. 查看swarm 节点信息 docker node ls

   $ docker node ls
   
   ID                           HOSTNAME  STATUS  AVAILABILITY  MANAGER STATUS
   dxn1zf6l61qsb1josjja83ngz *  manager1  Ready   Active        Leader
   

   docker swarm join-token manager

   docker info

   docker@swarm-master:~$ docker node ls
   ID                           HOSTNAME      STATUS  AVAILABILITY  MANAGER STATUS
