Docker使用swarm创建集群

初始化集群

docker swarm init --advertise-addr <MANAGER-IP>

$ docker swarm init --advertise-addr 192.168.99.101  //初始化管理节点
Swarm initialized: current node (e3nzsw54azshg1clkiithvl9f) is now a manager.

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

    docker swarm join \
    --token SWMTKN-1-2d3t6j9lub3c54lptjokjampxh1vxuu0rq78bfdmegbd9566yb-7oyake9bnhg448pf24m9cfsf8 \
    192.168.99.101:2377

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

添加工作节点到集群

（1）在工作节点进行添加

$ docker swarm join \
      --token SWMTKN-1-2d3t6j9lub3c54lptjokjampxh1vxuu0rq78bfdmegbd9566yb-7oyake9bnhg448pf24m9cfsf8 \
      192.168.99.101:2377
This node joined a swarm as a worker.

（2）在管理节点进行添加

$ docker swarm join-token worker

列出集群节点

在管理节点manager输入

$ docker node ls
ID                           HOSTNAME  STATUS  AVAILABILITY  MANAGER STATUS
e3nzsw54azshg1clkiithvl9f *  manager   Ready   Active        Leader
i3pnnzfmi0wpxvuptlu3z9cqj    worker    Ready   Active
