Hi, just tried to setup Discourse and all went good except for launching it.  
It gives the following error:

```
starting up existing container
+ /usr/bin/docker start app
Error response from daemon: Cannot start container app: Error starting userland proxy: listen tcp 0.0.0.0:80: bind: address already in use
FATA[0000] Error: failed to start one or more containers

```

Which suggests the port is already in use. On the system we run a web (apache, teamspeak and minecraft server.  
I am not the best with Linux and Apache, so I was wondering if anyone could help.

Thanks in advance, if you need any more information, let me know.

Regards,  
Exuraz
