This is done in preparation for adding reverse-proxy configurations
Unfortunately a later docker-compose file cannot *remove* a port
binding, so it has to be removed in the root file.
If there is interest, the 80:8000 binding can be re-added in a
new docker-compose overwrite file.
I got confused why I couldn't log in even though the credentials were correct.
Turns out you're supposed to remove the brackets around the env variables - I didn't knew that. I think this will prove less confusing
