client-go开发自定义operator

开发operator一共分为5步骤

一、创建config

config的创建有两种方式

1、clientcmd.BuildConfigFromFlags

config, err := clientcmd.BuildConfigFromFlags("", clientcmd.RecommendedHomeFile)
	if err != nil {
		//访问集群内
		inClusterConfig, err := rest.InClusterConfig()
		if err != nil {
			log.Fatalln("can't get config")
		}
		config = inClusterConfig
	}
