通过`kubectl api-resources`找到我们需要的API资源，编写正确的YAML资源清单文件，但是kubernetes中资源对象太多了，不可能都记住，这时候可以借助`kubectl explain`命令来找到完整的结构 ``` root@cn-office-crm-qa-all-k8s01:~# kubectl explain deployments 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 metadata. spec <Object> Specification of the desired behavior of the Deployment. status <Object> Most recently observed status of the Deployment. ``` #### **输出顶层的属性，`<string>` 表示字符串，`<Object>`表示对象，[] 表示数组，对象在YAML文件中需要缩进，数组就需要通过添加一个破折号来表示一个item** 对于对象和数组我们不知道里面有什么属性，我们可以继续查看`kubectl explain deployments.metadata` 或者 `kubectl explain deployments --recursive` **这个命令可以将资源对象的完整属性列出来，而且缩进格式和YAML文件基本一致**
