095、如何创建Swarm集群？（Swarm02）

参考https://www.cnblogs.com/CloudMan6/p/7862254.html

 

本节我们将创建三节点的swarm集群（操作系统Ubuntu 16.04 ,Docker 版本均不低于 v1.12）。

 

host01    10.12.31.211    swarm-worker1

host02    10.12.31.212    swarm-worker2

host03    10.12.31.213    swarm-manager

  

root@host03:~# docker swarm init --advertise-addr 10.12.31.213    #    创建docker swarm

Swarm initialized: current node (h6rzavsz2vjxstwj3pytiebjb) is now a manager.    #    第一个node自动成为 swarm-manager

 

To add a worker to this swarm, run the following command:    #    提供添加 swarm-manager的命令

 

    docker swarm join --token SWMTKN-1-1n5mp7iz3isz5nuw2jdbzw76fx2a11a7a3r09h9wvfn6r2n2jn-3tnqqxq8h3chq8izf65e07379 10.12.31.213:2377

 

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.    #    提供添加 swarm-worker 的命令

 

root@host03:~# docker node ls    #    查看当前node节点

ID                            HOSTNAME            STATUS              AVAILABILITY        MANAGER STATUS      ENGINE VERSION

h6rzavsz2vjxstwj3pytiebjb *   host03              Ready               Active              Leader              18.09.6

 

root@host01:~# docker swarm join --token SWMTKN-1-1n5mp7iz3isz5nuw2jdbzw76fx2a11a7a3r09h9wvfn6r2n2jn-3tnqqxq8h3chq8izf65e07379 10.12.31.213:2377

This node joined a swarm as a worker.    #    host01 加入swarm集群，并设置为worker

 

root@host02:~# docker swarm join --token SWMTKN-1-1n5mp7iz3isz5nuw2jdbzw76fx2a11a7a3r09h9wvfn6r2n2jn-3tnqqxq8h3chq8izf65e07379 10.12.31.213:2377

This node joined a swarm as a worker.    #    host02 加入swarm集群，并设置为worker

 

root@host03:~# docker node ls
