Hi Xu,

Yeah, these are similar to the ideas I heard via Lantao. My thought behind
the issue I created was to try and find a solution that is generic enough
to be built mostly into the containerd CRI plugin. But it may be that
adding port-forward to the shim API and having shim implementations be
fully responsible for port-forwarding might be easier. I'm curious what you
think.

BTW, for your solution 1, where would socat come from and how would it be
executed? Would that be in a container? Or would the kata shim do it
similarly to how containerd used to do it and run the socat found on the
Kata guest VM but inside the Pod ns (i.e. outside Pod cgroup)?
