问题描述
我有一个简单的 Nginx pod 和一个带有 k0s 二进制文件的 k0s 集群设置。现在我想连接到那个 pod，但我收到这个错误：
$ kubectl port-forward frontend-deployment-786ddcb47-p5kkv 7000:80
error: error upgrading connection: error dialing backend: rpc error: code = Unavailable
desc = connection error: desc = "transport: Error while dialing dial unix /var/lib/k0s/run/konnectivity-server/konnectivity-server.sock: connect: connection refused"
我不明白为什么会发生这种情况以及为什么它试图访问我机器上不存在的 /var/lib/k0s/run/konnectivity-server/konnectivity-server.sock。
我是否必须将带有 k0s 的本地开发机器添加到集群中？
从pod describe中提取：

解决方法
解决方法是删除文件。
/var/lib/k0s/run/konnectivity-server/konnectivity-server.sock 并重新启动服务器。
目前我的 github 问题仍未解决。
