Is it possible to support domain sockets on Ruby (client & server) and PHP(client) with NGINX

[beu.al...@gmail.com]

Scenario:

I would like to have a microservice which should be replicated and built on top of GRPC and two clients: one written in PHP and the other one in Ruby. 

Problem:

Currently, NGINX has support for HTTP2 but it doesn't support reverse proxy. 

From my understanding, GRPC supports domain sockets but only for core(C) and Go ???

Is there a way to use domain sockets with Ruby and PHP  with NGINX ??? Or maybe use HTTP 1?

Thanks in advance!

NGINX now supports HTTP2 in reverse proxy mode. Do you still find use for support for UDS?
