Requirement

I want to put a reverse proxy in front of the customer. I want to give the frontend portA (which goes to the proxy) and the customer portB (which is what the customer listens on).

Problem

I want to be able to run the four services that make up the hot rod example separately. This will give users of the example more fine-grained control over ports. Unless I'm mistaken, this currently won't work until the example accepts flags that can override host address 0.0.0.0. Currently, when I run all four, in the logs, I see the customer listening on 0.0.0.0:8081, but the frontend fails to connect to 0.0.0.0:8081.

Proposal

Accept flags that can override host address 0.0.0.0.
