docker swarm

上次安装完了docker，继续探索swarm，Swarm和Kubernetes比较类似，但是更加轻，具有的功能也较kubernetes更少一些。

先安装完docker

1、机器10.100.25.83上：

初始化一个Swarm群集：docker swarm init

[no yum.repos.d]# docker swarm init
Swarm initialized: current node (puaz9qdi3bkxak3w4gly2fjxg) is now a manager.

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

    docker swarm join     --token SWMTKN-1-0kuf7ygj39r5g0gy5jsmdt99viykg8b7jb5j52hu3ipn1sq3ww-831xku6gv525oy3o07wncdsk1     10.100.25.83:2377

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

2、机器10.100.25.13上：

[ ~]# docker swarm join >     --token SWMTKN-1-0kuf7ygj39r5g0gy5jsmdt99viykg8b7jb5j52hu3ipn1sq3ww-831xku6gv525oy3o07wncdsk1 >     10.100.25.83:2377
This node joined a swarm as a worker.

3、在 manager 端10.100.25.83查看 swarm 节点信息

[ ~]# docker node ls
ID                           HOSTNAME                       STATUS  AVAILABILITY  MANAGER STATUS
puaz9qdi3bkxak3w4gly2fjxg *  ecsnpmeybwpxc-no.01.novalocal  Ready   Active        Leader
tzu5x27v5a3rqnmglh15z1cx9    prodgateway-no.05.novalocal    Ready   Active

节点2台机器都展示了

关于swarm怎么使用及监控，待续
