095、如何创建Swarm集群?(Swarm02)
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
