如何使用go-client重新启动kubernetes中的部署

    clientset, err := kubernetes.NewForConfig(config)

        return nil, err

    return clientset, nil

    _, err = deploymentsClient.Update(context.TODO(), deployment, metav1.UpdateOptions{})
    if err != nil {

    }

    return nil
}

func main() {
    namespace := "your-namespace"

    clientset, err := createClient()
    if err != nil {

    fmt.Println("Deployment restarted successfully.")
}
