Install kubernetes without yum
下载最新版本：
https://github.com/kubernetes/kubernetes/releases
下载kubernetes.tar.gz即可
解压缩后到cluster目录下
执行get-kube-binaries.sh
执行目录要控制好，这个脚本会自动下载client与server相关的文件，会自动放到kubernetes目录下
随后在相应的bin下就可以找到对应的文件
kube-apiserver kube-controller-manager kube-scheduler kubelet kubectl kube-proxy
在cluster目录下有对应操作系统的文件夹，可以找到相关的script,直接运行，或者参照脚本来启动服务
下边是直接编写service文件的内容
重复上边的工作到每个集群节点
在集群节点中需要安装必要的组件
docker etcd flanneld （安装方式自选）
到master节点需要执行
kube-apiserver kube-controller-manager kube-scheduler
work节点需要运行
kubelet kube-proxy
随后的工作与yum安装的步骤类似
配置相关文件等
启动方式可以按照service启动的方式来启动
编写service文件

文件中目录自行调整
可以参考
https://github.com/kubernetes/kubernetes/tree/master/cluster/centos
下边的一些shell
目前官方文档不是很详细，版本更新又很快。
