繼續裝Kubelet .....
可參考我的 git .......https://github.com/echochio-tw/CoreOS-Kubelet-Script
抓 git 最快 ....跑 script 就裝好了
下面就詳述如何安裝的 ......
抓 kubectl
先看最新版本 用瀏覽器看 https://github.com/kubernetes/kubernetes/releases
現在是 1.6.0 .....不要抓 bata 版 .....
抓檔案 ...放到 /opt/bin ....三台都做

master 要有這些 service :
apiserver.service
controller-manager.service
node 要有這些 service :
scheduler.service
proxy.service
kubelet.service
先做 apiserver.service

上線可看到
三個 node 都加上 kubelet.
如果無法用 /opt/bin/kubectl ...要改檔案 ~/.kube/config 內容是
apiVersion: v1
clusters:
- cluster:
server: http://192.168.0.69:8080
name: default-cluster
contexts:
- context:
