应的深拷贝方法。如果你有一些类型不需要深拷贝或无法定义深拷贝行为，
你可以通过局部标签来指明不需要为其生成深拷贝方法：
// +k8s:deepcopy-
gen=false
。如果没有启用包级别的深拷贝代码生成功能，也可以通过标签指
定为部分类型生成深拷贝方法：
// +k8s:deepcopy-gen=true
。
例子中的第二个标签
// +groupName=example.com
定义了
API
组的全名。如
果
Go
的父包名与组名不一致，就可以通过这个标签来指定组名。
上面的这个例子选自
cnat client-go
示例中的
pkg/apis/cnat/v1alpha1/doc.go
文件（参见“
6.2
基于
sample-controller
”）。其中，
cnat
是父包名，而组名
是
cnat.programming-kubernetes.info
。
通过使用
// +groupName
标签，客户端代码生成器（参考“
4.4.2.3
通过
client-gen
生成强类型客户端”）才能生成使用正确
HTTP
路径
/apis/foo.
project.example.com
的客户端。除了
+groupName
还有一个名为
+groupGoName
的标签，用于自定义
Go
的标识符（用于变量和类型的名字）。在默认情况下，
代码生成器会使用父包名作为标识符的名字。比如：默认情况下，代码生成
器会使用首字母大写的父包名来作为标识符，比如我们例子中就是
Cnat
。但
是对于“云原生
At
”这个名字来说，更好的标识符应该写成 ...
