代码结构

kubernetes 代码组织方式

<src_root>
|—-api
|--openapi-spec
|    |--swagger.json  // openapi 定义
|--cmd // main函数所在的目录，可执行文件源代码入口
|    |--kube-apiserver
|        |--apiserver.go
|--pkg  // 实现逻辑所在目录
|--hack // 编译脚本
|--plugin // 插件代码，认证和准入插件
|--staging // 保存会复制到其它repo的源代码，比如k8s对象定义
|--test // e2e 代码
|--vendor // 依赖包

openAPI是api定义的标准规范，Kubernetes主要遵循 Schema Object
