How to set up project with docker and deepstream.io? - docker

Question

https://github.com/PhillippOhlandt/deepstream-turn-based-game-demo
I cloned this repo and am trying to get it up and running but think I am missing a step.
I run npm install inside the folder, and I have also installed docker on my mac. Then I run docker-compose up and it starts up. When I go to localhost nothing happens?
I don't think I fully understand what's going on here...

The game demo is working, but the creators should add a few lines of friendly manual. However, don't worry, I'll cover it for you here.
After running docker-compose up open up your browser at http://localhost:8088/
Enter Username: userA Password: password
Create a new game and note the GameID
Open up another browser tab at http://localhost:8088/
Enter Username: userB Password: password
Join the game by previously noted GameID and you can start playing already.
The game supports up to 4 users and in authors' defense, they created a youtube video, but forgot to provide some useful instructions, like what the password is.
