一、前言

  1.     打算开一个专栏，写一些k8s中遇到的问题，不定时更新。

报错信息：

  1. Error: could not get apiVersions from Kubernetes: unable to retrieve the complete list of server APIs: custom.metrics.k8s.io/v1beta1: the server is currently unable to handle the request

1、查找到出问题的apiservice

  1. kubectl get apiservice

可以看到其中有出现false状态的apiservice,删除出问题的apiservice故障即可解决。

2、删除出问题的apiservice

  1. kubectl delete apiservce <service-name>
