当我尝试运行时，kubectl top nodes我得到了输出：
Error from server (ServiceUnavailable): the server is currently unable to handle the request (get nodes.metrics.k8s.io)
指标服务器能够在获取指标的日志中抓取指标
ScrapeMetrics: time: 49.754499ms, nodes: 4, pods: 82
...Storing metrics...
...Cycle complete...
但是缺少指标服务的端点，我该如何解决这个问题？
kubectl get apiservices |egrep metrics
v1beta1.metrics.k8s.io kube-system/metrics-server False (MissingEndpoints)
任何帮助将不胜感激！
