Wie kann ich CustomResourceDefinitions (CRDs) in Kubernetes mit Client-go ansehen?

<code class="go">import (
    "github.com/pkg/errors"
    corev1 "k8s.io/api/core/v1"
    metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"

    "k8s.io/client-go/tools/cache"
    "k8s.io/client-go/tools/remotecommand"
)

// watchCRD watches for new/changed CustomResourceDefinitions (CRDs).
func watchCRD() error {
    // Create a new Kubernetes clientset.
    clientset, err := kubernetes.NewForConfig(restConfig)
    if err != nil {
        return errors.WithStack(err)
    }

    // Create an informer for list of CRDs.
    sharedInformerFactory := informers.NewSharedInformerFactory(clientset, 0)
    crdInformer := sharedInformerFactory.ApiextensionsV1().CustomResourceDefinitions().Informer()

    // Initialize the informer and wait for it to sync with API server.
    stopCh := make(chan struct{})
    crdInformer.AddEventHandler(cache.ResourceEventHandlerFuncs{
        AddFunc: func(obj interface{}) {
            crd := obj.(*apiextensionsv1.CustomResourceDefinition)
            // Handle newly added CRD.
            fmt.Println("New CRD added:", crd.Name)
        },
        UpdateFunc: func(oldObj, newObj interface{}) {
            crd := newObj.(*apiextensionsv1.CustomResourceDefinition)
            // Handle updated CRD.
            fmt.Println("CRD updated:", crd.Name)
        },
        DeleteFunc: func(obj interface{}) {

        },
    })
    sharedInformerFactory.Start(stopCh)
    <-wait.NeverStop

    return nil
