echochio

1. 將所有的 docker server 的 docker 遠端 port 打開 ......例如有三台 node 都打開 
(PS 我的是 CentOS 7 ...OS 不同 docker config 位置也不同 ...設定也不同 .......)

# echo "OPTIONS='-g /cutome-path/docker -H tcp://0.0.0.0:2375'" > /etc/sysconfig/docker

2. 設完要重啟 docker ....

# systemctl restart docker 

2. 在 master 設定 cluster 檔案

# echo 192.168.0.70:2375 >> cluster
# echo 192.168.0.71:2375 >> cluster
# echo 192.168.0.72:2375 >> cluster

3. 建立 swarm  manage

# docker run -d -p 8888:2375 -v $(pwd)/cluster:/tmp/cluster swarm manage file:///tmp/cluster

4. 在master 看成果

# docker -H 192.168.0.70:8888 info

ps 我 node 用 photon 做的 .....
安裝 photon  請參考 http://echochio.pixnet.net/blog/post/44899804

# echo 192.168.0.71:2375 > cluster
# echo 192.168.0.72:2375 >> cluster
# docker run -d -p 8888:2375 -v $(pwd)/cluster:/tmp/cluster swarm manage file:///tmp/cluster
