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，但是我得到了这个错误：
$ 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/var/lib/k0s/run/konnectivity-server/konnectivity-server.sock我的机器上不存在的。
我是否必须将带有 k0s 的本地开发机器添加到集群中？
