k9s：无法连接到 kubernetes 集群

Question

我正在使用 k9s 工具来管理 kubernetes 集群（Google Cloud Platform 上的 GKE）。

最近k9s停止工作并停止连接到k8s集群。

当我启动 k9s（即k9s -n default）时，它会显示所有集群的上下文，当我单击其中一个上下文时

错误是

Unable to connect to context "XXXXXXXXXX"

它向我显示了以下错误，如屏幕截图所示。

但是对于kubectl客户端来说，它工作正常并显示集群的所有数据。

我尝试重新安装 k9s 并更新其版本，但问题仍然存在。

如何调试问题并解决问题？

调查、检查日志后，您可以通过运行获取日志位置

日志向我显示了这个错误。

我意识到这是因为我的 kubectl 客户端最近更新了，因此 k9s 停止连接到 k8s。

\n

请点击该链接，因为在较新的 kubectl 版本中，gke 的 kubectl 身份验证发生了一些变化。

再次对我的集群进行了验证

\n

gcloud container clusters get-credentials $CLUSTER_NAME --region $REGION_NAME --project $PROJECT_NAME\n

它又起作用了。
