Docker Compose Not Working

[atb-brown]

My apologies in advance, but I'm not a Docker expert. But following the outline in this project's readme doesn't result in a running service for me right now.

When running docker-compose up, I get the following output with an error:

$ docker-compose up -d

It seems to be complaining that 0.0.0.0:8080 is already being used, but I used a TCP port viewer and that doesn't seem to be the case on my computer.

Hi @atb-brown ,

As you see at the docker-compose file, 2 instances of the app are trying to run on the same port and then one of them can not run. You can simplify the compose file like this:
