説明

The exact command to reproduce the issue: minikube ip

But the truth is, I kept minikube tunnel running for a while. I can access everything using kubectl, but when I want to do any command that communicates with the cluster in any way, it just hangs.

I have done nothing special, just minikube start, in an other window minikube tunnel.

I also tried minikube tunnel --cleanup,did not fail, but did nothing either.

Then i tried minikube ip -v=7: Using SSH client type: native &{{{ 0 [] [] []} docker [0x83b580] 0x83b550 [] 0s} 127.0.0.1 37871 } About to run SSH command: ip addr show

and after a while: Error dialing TCP: ssh: handshake failed: read tcp 127.0.0.1:35568->127.0.0.1:37871: read: connection reset by peer

The full output of the command that failed: It just hangs no output.

The output of the minikube logs command: That just hangs too.

The operating system version: Kubuntu 17.10

調査方針
Investigate the SSH handshake failure when minikube tunnel runs for a long time. Check the tunnel implementation in minikube (likely in pkg/minikube/tunnel or similar). Review the error 'connection reset by peer' to determine if it's a network timeout or an SSH keepalive issue. Look for any existing fixes or related issues in the repository.
