Support Kubernetes port forwarding
Currently port forwarding doesn't work for gVisor because the port needs to be forwarded from inside the sandbox.

@ianlewis is there any alternative to port-forwarding with gVisor at the moment?

@tomenden would you mind sharing the use case where you use port forward?

@milantracy Sure. I have a process running node.js in a container and I would like to be able to debug it remotely. This is very powerful, and works perfectly without gVisor.
See this blog post for reference.
There has been some progress to implement port forwarding on the gVisor side in #8391 and #8785 but IIRC containerd still requires some changes to the shim protocol to make this work.
https://github.com/containerd/containerd/issues/6638 is where that work is tracked.
