如何使用 RESTClient 建立和檢索自訂 Kubernetes 資源？

<code class="go">import "k8s.io/client-go/rest"

func CreateCustomResource() error {
    // Construct the full path to the custom resource
    absPath := "/apis/configuration.konghq.com/v1/namespaces/default/kongplugins"

    // Marshal the custom resource data into a byte array
    body, err := json.Marshal(customResource)
    if err != nil {
        return err
    }

    // Create a RESTClient using in-cluster configuration
    confs, err := rest.InClusterConfig()
    if err != nil {
        return err
    }
    client, err := rest.RESTClientFor(confs)
    if err != nil {
        return err
    }

    // Make a POST request to create the custom resource
    _, err = client.Post().AbsPath(absPath).Body(body).DoRaw()
    if err != nil {
        return err
    }

    return nil
}</code>

<code class="go">import "k8s.io/client-go/rest"

func GetCustomResource() (*CustomResource, error) {
    // Construct the full path to the custom resource
    absPath := "/apis/configuration.konghq.com/v1/namespaces/default/kongplugins/kongplugin-sample"

    // Create a RESTClient using in-cluster configuration
    confs, err := rest.InClusterConfig()
    if err != nil {
        return nil, err
    }
    client, err := rest.RESTClientFor(confs)
    if err != nil {
        return nil, err
    }

    // Make a GET request to retrieve the custom resource
    data, err := client.Get().AbsPath(absPath).DoRaw()
    if err != nil {
        return nil, err
    }

    // Unmarshal the JSON response into the custom resource object
    customResource := &CustomResource{}
    if err := json.Unmarshal(data, customResource); err != nil {
        return nil, err
    }

    return customResource, nil
