Description

Hi all,

I'm quite new to this project and I've started investigating its potential usage in Kubernetes.
I've found in past that using Unix Domain Sockets across several containers in the same pod gives an interesting performance boost and drastically reduces the overhead of going through the network stack. Given that containers in a pod run in the same host, it's perfectly reasonable to let them communicate through unix domain sockets.

If you're interested in such feature, I'm more than willing to help implementing that, given that I need a few pointers where to start from
