当我尝试使用kubectl top nodes时，出现此错误:
Error from server (NotFound): the server could not find the requested resource (get services http:heapster:)
但是不推荐使用heapster，而我正在使用kubernetes 1.11。我安装了metrics-server，但仍然遇到相同的错误，当我尝试检查metrics-server的日志时，看到此错误:

最佳答案
据报道。

合并为https://github.com/kubernetes/kubernetes/pull/56206
可能已在1.12中修复，或计划在下一个版本中使用。
