为kubernetes入口对象制作注释补丁

我为kubernetes编写了mutating webhook,将默认类添加到新的入口对象。

核心部分是this

func patch( annotations map[string]string, name string) []byte {
        var patches []Patch
        if len(annotations) == 0 {
                klog.V(0).Infof("New annotation to %v.\n", name)
                patchNew := Patch{"add", "/metadata/annotations", map[string]string{}}
                patches = append(patches, patchNew)
        }
        if _, ok := annotations[key]; !ok {
                klog.V(0).Infof("Added class %v to %v.\n", Class, name)
                patchAdd := Patch{"add", "/metadata/annotations/" + strings.Replace(key, "/", "~1", -1), Class}
                patches = append(patches, patchAdd)
        } else {
                klog.V(0).Info("No need to add class.\n")
        }
        bytes, _ := json.Marshal(patches)
        return bytes
}

它可以工作,但是感觉很笨拙。此解决方案有意义吗,还是有一种更简单的方法来达到相同的结果?

(我不会做太多编程工作,欢迎进行任何改进。)
