kubernets saltstack

前面手動安裝了kubernets，但是過程比較繁瑣，也不容易重復，今天有時間寫了一個使用saltstack來安裝kubernets。
1.已知問題：
用於加入node接天的token需要手動修改
環境：
centos7.2 2c+4g+40 saltmaster
centos7.2 2c+4g+40 saltminion k8s-master
centos7 2c +2g saltminion k8s-node1
本環境默認已經修改了主機名和關閉了防火墻，安裝好saltminion,如果不知道怎麽做可以看看cobbler，系統初始化安裝的時候全部搞定。
saltstack安裝master思路：
1.安裝docker並啟動，註意docker版本，官網明確表示最多到17.03
2.同步kubernetsyum源
3.安裝kubernets
4.修改配置文件
5.啟動kubernets
6.初始化kubernets
7.將節點加入集群
8.測試

    部署2個nginx服務做測試：
    kubectl run nginx --image=nginx --replicas=2 --labels="run=load-tomct-example" --port=8089
    查看服務是否啟動：
