我如何调试和修复这个问题?

要诊断kubectl命令，在运行该命令时选择一个冗长级别。如果你运行kubectl -v=9，你会得到大量的调试输出。
如果你查看这里，你可能会发现你的缓存目录在。kube中的权限是无效的。
I0511 09:28:13.431116 260204 cached_discovery.go:87] failed to write cache to /home/$USER/.kube/cache/discovery/CLUSTER_NAME/security.istio.io/v1beta1/serverresources.json due to mkdir /home/$USER/.kube/cache/discovery: permission denied
为了解决这个问题，我简单地设置了允许写入缓存数据的权限。
chmod 755 -R ~/.kube/cache
这就解决了我的问题，希望对别人有帮助。
删除sudo rm -rf ~/.kube/cache/
这对我很有效。别在这件事上花太多时间了
根据Red Hat的说法，由于RHOCP集群中安装的自定义资源定义(crd)数量的增加，到达API发现的请求受到客户端代码的限制。
我的OpenShift集群上有很多crd，我观察到了这个问题。在你的Kubernetes集群上也是这样吗?
更新kubectl版本对我有效。
原因是kubernetes发现缓存。
