【Go】Client-goでLabelSelectorを使って指定したラベルのPodのみを抽出したい

package main

import (
    "context"
    "encoding/json"
    "fmt"
    metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
    "k8s.io/client-go/kubernetes"
    "k8s.io/client-go/tools/clientcmd"
    "log"
    "os"
    "path/filepath"
)

func main() {
    // Kubeconfigのファイルパスを指定
    kubeconfig := filepath.Join(os.Getenv("HOME"), ".kube", "config")
    config, err := clientcmd.BuildConfigFromFlags("", kubeconfig)
    if err != nil {
        log.Fatal(err)
    }

    // Kubeconfigを読み込む
    clientset, err := kubernetes.NewForConfig(config)
    if err != nil {
        log.Fatal(err)
    }

    // Pod一覧を呼び出す
    namespace := "default"
    pods, err := clientset.CoreV1().Pods(namespace).List(context.TODO(), metav1.ListOptions{
        LabelSelector: "app=vamdemic111aaa-app",
    })
    if err != nil {
        log.Fatalln("failed to get pods:", err)
    }

    m := map[string]string{}

    for _, pod := range pods.Items {
       m[pod.Name] = string(pod.Status.Phase)
    }

    data, _ := json.Marshal(m)
    fmt.Printf(string(data))
}
