 ## CustomResourceDefinitions

 API 资源允许你定义定制资源。
 定义 CRD 对象的操作会使用你所设定的名字和模式定义（Schema）创建一个新的定制资源，
 Kubernetes API 负责为你的定制资源提供存储和访问服务。
-CRD 对象的名称必须是合法的
-[DNS 子域名](/zh-cn/docs/concepts/overview/working-with-objects/names#dns-subdomain-names)。
+CRD 对象的名称必须是有效的 [DNS 子域名](/zh-cn/docs/concepts/overview/working-with-objects/names#dns-subdomain-names)，
+该名称由定义的资源名称及其 API 组派生而来。有关详细信息，
+请参见[如何创建 CRD](/zh-cn/docs/tasks/extend-kubernetes/custom-resources/custom-resource-definitions#create-a-customresourcedefinition)。
+此外，由 CRD 定义的某种对象/资源的名称也必须是有效的 DNS 子域名。
