调用代码生成器
通常来说，所有控制器项目中都会用类似的方法来使用代码生成器。只不过
是包名、组名和
API
版本可能会有所差异。在构建系统中为自定义资源生成
代码的最简单的方法是直接调用
k8s.io/code-generator/generate-groups.sh
或
hack/update-codegen.sh
这两个
Bash
脚本（参考本书的
GitHub
仓库）。
注意，有些项目会直接调用代码生成器的二进制程序，因为它们有一些特别
的需求或者仅仅是因为历史原因。对于构造一个自定义资源的控制器这样的
需求，还是推荐使用来自
k8s.io/code-generator
仓库的
generate-groups.sh
脚本，
因为它使用起来更为简单：
$ vendor/k8s.io/code-generator/generate-groups.sh all \
github.com/programming-kubernetes/cnat/cnat-client-go/pkg/generated
github.com/programming-kubernetes/cnat/cnat-client-go/pkg/apis \
cnat:v1alpha1 \
--output-base "${GOPATH}/src" \
--go-header-file
“
hack/boilerplate.go.txt
”
这个命令中的
all
意味着将调用实现自定义资源所需要的四种标准的代码生
成器：
deepcopy-gen ...
