)

func main() {
	cfg, err := rest.InClusterConfig()
	if err != nil {
		panic(err.Error())
	}
	// Use this to trace all calls made to the Kubernetes API
	cfg.WrapTransport = kubernetestrace.WrapRoundTripper

	client, err := kubernetes.NewForConfig(cfg)
	if err != nil {
		panic(err.Error())
	}

	pods, err := client.CoreV1().Pods("default").List(meta_v1.ListOptions{})
