 Basically, you need to specify the port that the apache container shall use and modify the startup command a bit.
 
 All examples below will use port `11000` as example apache port. Also it is supposed that the reverse proxy runs on the same server like AIO, hence `localhost` is used and not an internal ip-address to point to the AIO instance. Modify both to your needings.
