如何使用client-go访问kubernetes CRD？

import (
    "context"
    "fmt"
    metav1 "k8s.io/apimachinery/pkg/apis/meta/v1"
    "k8s.io/client-go/kubernetes"
    "k8s.io/client-go/tools/clientcmd"
)

config, err := clientcmd.BuildConfigFromFlags("", "/path/to/kubeconfig")
if err != nil {
    panic(err.Error())
}
clientset, err := kubernetes.NewForConfig(config)
if err != nil {
    panic(err.Error())
}

crdClient := clientset.Resource("your-crd-group/your-crd-version").Namespace("your-namespace")

crdObj := &unstructured.Unstructured{
    Object: map[string]interface{}{
        "apiVersion": "your-crd-group/your-crd-version",
        "kind":       "YourCRD",
        "metadata": map[string]interface{}{
            "name":      "your-crd-name",
            "namespace": "your-namespace",
        },
    },
}

result, err := crdClient.Get(context.TODO(), "your-crd-name", metav1.GetOptions{})
if err != nil {
    panic(err.Error())
}
fmt.Printf("YourCRD: %v\n", result)

_, err = crdClient.Create(context.TODO(), crdObj, metav1.CreateOptions{})
if err != nil {
    _, err = crdClient.Update(context.TODO(), crdObj, metav1.UpdateOptions{})
    if err != nil {
        panic(err.Error())
    }
}

err = crdClient.Delete(context.TODO(), "your-crd-name", metav1.DeleteOptions{})
if err != nil {
    panic(err.Error())
}
