在创建不同的资源时，发现yaml文件用到的api版本不一样。 本文主要讲如何api版本的选择。
在你的k8s集群执行命令，查看你的k8s 提供的api 和版本信息，输出列格式：
- NAME 资源名称
- SHORTNAMES 资源名称简写
- NAMESPACED 是否需要指定命名空间
- APIGROUP => apiVersion
- KIND 资源类型
- VERBS 可用的方法

KIND: Deployment
VERSION: apps/v1
DESCRIPTION:
Deployment enables declarative updates for Pods and ReplicaSets.
FIELDS:
apiVersion <string>
APIVersion defines the versioned schema of this representation of an
object. Servers should convert recognized schemas to the latest internal
value, and may reject unrecognized values. More info:
https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources
kind <string>
Kind is a string value representing the REST resource this object
represents. Servers may infer this from the endpoint the client submits
requests to. Cannot be updated. In CamelCase. More info:
https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds
metadata <Object>
Standard object's metadata. More info:
https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata
spec <Object>
Specification of the desired behavior of the Deployment.
status <Object>
Most recently observed status of the Deployment.
