go client-go 连接k8s

准备kubeconfig文件，自行准备
安装依赖包

 go get k8s.io/client-go@v0.20.10

开始连接

const (
   kubeConfig = "config/kubectl.kubeconfig"
)
func main(){
   conf, err := clientcmd.BuildConfigFromFlags("", kubeConfig)
   if err != nil {
   	fmt.Println("获取kubeconfig错误 ", err)
   }

   clientSet, err := kubernetes.NewForConfig(conf)
   if err != nil {
   	fmt.Println("clientSet错误 ", err)
   }
   pods, err := clientSet.CoreV1().Pods("default").List(context.TODO(), metav1.ListOptions{})
   if err != nil {
   	fmt.Println("获取pod异常 ", err)
   }
   for _, pod := range pods.Items {
   	fmt.Println(pod.Name, pod.Namespace, pod.CreationTimestamp)
   }
}

执行则可以打印pod的信息
