如果你有一个“通用”runtime.Object，你可以在client-go中使用dynamic client来实现这个目标。动态客户端处理unstructured.Unstructured对象，所有runtime.Object都可以转换为它。下面是一个示例：

// create the dynamic client from kubeconfig
dynamicClient, err := dynamic.NewForConfig(kubeconfig)
if err != nil {
    return err
}
    
// convert the runtime.Object to unstructured.Unstructured
unstructuredObj, err := runtime.DefaultUnstructuredConverter.ToUnstructured(obj)
if err != nil {
    return err
}
    
// create the object using the dynamic client
nodeResource := schema.GroupVersionResource{Version: "v1", Resource: "Node"}
createdUnstructuredObj, err := dynamicClient.Resource(nodeResource).Namespace(ns).Create(unstructuredObj)
if err != nil {
    return err
}

// convert unstructured.Unstructured to a Node
var node *corev1.Node
if err = runtime.DefaultUnstructuredConverter.FromUnstructured(createdUnstructuredObj, node); err != nil {
    return err
}

这是正确的，你需要动态客户端，但要保持运行时的通用性。对象，你需要使用DiscoveryRESTMapper，它需要使用类型化的客户端来发现可用的API版本：

dynClient, err := dynamic.NewForConfig(config)
...
clientset, err := kubernetes.NewForConfig(config)
...
gvk := obj.GroupVersionKind()
gk := schema.GroupKind{Group: gvk.Group, Kind: gvk.Kind}
groupResources, err := restmapper.GetAPIGroupResources(clientset.Discovery())
...
rm := restmapper.NewDiscoveryRESTMapper(groupResources)
mapping, err := rm.RESTMapping(gk, gvk.Version)
...
dynClient.Resource(mapping.Resource).Namespace("default").Create(obj, metav1.CreateOptions{})
