Envoy as a reverse proxy and load balancer for unix sockets

Question

I have the following issue: envoy should do reverse proxy to numerous unix sockets such as:

/var/run/node1.sock
/var/run/node2.sock
...

and so on. None of configuration i tried work, envoy even not start. Can someone explain how to reverse proxy even to single unix socket ?

SOLVED:

     - lb_endpoints:
        - endpoint:
            address:
              pipe:
                path: /var/run/node1.sock
        - endpoint:
            address:
              pipe:
                path: /var/run/node2.sock
