If you're using a reverse-proxy, why bother mapping ports at all?
Absolutely, it is not necessary if the proxy can reach the service in other ways (e.g. a shared network). Some non-http services don't like to be proxied though. Some constellations where the proxy is not on the same host as the containers may also make it necessary. My answer was based on the possibility to not have the same inside/outside port, not necessarily the need though😉
