saltsatck自动化安装kubernets v1.10.1

前面手动安装了kubernets，但是过程比较繁琐，也不容易重复，今天有时间写了一个使用saltstack来安装kubernets。
1.已知问题：
用于加入node接天的token需要手动修改
环境：
centos7.2 2c+4g+40 saltmaster
centos7.2 2c+4g+40 saltminion k8s-master
centos7 2c +2g ?saltminion k8s-node1
本环境默认已经修改了主机名和关闭了防火墙，安装好saltminion,如果不知道怎么做可以看看cobbler，系统初始化安装的时候全部搞定。
saltstack安装master思路：
1.安装docker并启动，注意docker版本，官网明确表示最多到17.03
2.同步kubernetsyum源
3.安装kubernets
4.修改配置文件
5.启动kubernets
6.初始化kubernets
7.将节点加入集群
8.测试

    部署2个nginx服务做测试：
    kubectl run nginx --image=nginx ?--replicas=2 --labels="run=load-tomct-example" --port=8089
    查看服务是否启动：
