Kubernetes 服务器错误（ServiceUnavailable）：服务器当前无法处理请求（get nodes.metrics.k8s.io）

运行“kubectl top nodes”时出现错误：

服务器错误（ServiceUnavailable）：服务器当前无法处理请求（get nodes.metrics.k8s.io）

并且没有系统错误日志。 我如何解决这个问题

---

操作系统is:CentOS Linux 7.5.1804版（核心版）

此问题已解决：

删除代理（

文件：/etc/kubernetes/manifests/kube-apiserver.yaml

）

重新启动kubelet服务

---

kubectl top nodes

现在应该可以工作了

如果您使用kubectl get apiservice v1beta1.metrics.k8s.io-o yaml，状态看起来正常吗？
