Add getPort() or similar to ServerImpl

I noticed that there doesn’t seem to be a way to programatically retrieve a way to get the port a ServerImpl is listening on. Could we add a method that provides this information?

I would argue it’s useful for when one wants to bind to port 0 i.e.

ServerImpl server = NettyServerBuilder.build();
server.start()

System.out.println("Server listening on port " + server.getPort());

Any news on the issue? It is super-important for unit-tests. When running unit-tests you need to bind on random port, because otherwize tests occasionally fail giving headaches to developers.

AFAIU, this feature can be implemented easily, it just needs to be decided what API should look like.

I’d prefer ServerImpl to have getPort() function that returns 0 if server is not listening on IP.

I am marking this as closed, even though there may be more followup work for exposing the SocketAddress.
