一：简介
k8s API Server提供了k8s各类资源对象（pod,RC,Service等）的增删改查及watch等HTTP Rest接口，是整个系统的数据总线和数据中心。功能特性：
1.是集群管理的API入口
2.是资源配额控制的入口
3.提供了完善的集群安全机制

二：概述
通常可以通过命令行工具Kubectl来与API Server交互，它们之间的接口是REST调用，同时也可以使用curl命令行工具进行快速验证。通过配置参数KUBE_MASTER="--master=http://10.116.137.196:8080" 客户获得API Server的访问路径。

1.获取 API的版本信息
curl 10.116.137.196:8080/api

{
"kind": "APIVersions",
"versions": [
"v1"
],
"serverAddressByClientCIDRs": [
{
"clientCIDR": "0.0.0.0/0",
"serverAddress": "10.116.137.196:6443"
}
]
}

2.获取目前所支持的资源对象的种类
curl 10.116.137.196:8080/api
