kubectl exec

hangs and timeouts when trying to connect k3s API server via Traefik TCP ingress route? Other commands, including

port-forward

work.

> kubectl exec -i -t <...> -n <...> --v=9 -- /bin/sh

Are you trying to connect to rancher through Traefik, or just the apiserver? I don't think those would be related if you're not talking to rancher.

I mean I just want to get shell to a pod in k3s
