The purpose of the repository is to demonstrate how a proxy setup affects the services behind it.
This is a real world example (simplified) and used to give people a better understanding of the problem.
To get this running locally, you would need to install Docker, docker-compose and optionally make.
Then simply run it with:
make build run
This will build all the images used, and then run them. If everything goes well, you should now be able to access the setup on localhost:8080.
