Reverse Proxy Demo with NGINX

This demo showcases how to use an Nginx Reverse Proxy component to hide implementation details about which servers respond to which requests. It acts like a "programming interface".

Steps

1. Run docker compose up -d (make sure that port 8080 is open)
2. Run curl http://localhost:8080. This will show the /static/index.html file
3. Change the /static/index.html to another thing
4. Run curl http://localhost:8080 and see how the file changed
5. Run curl http://localhost:8080/somethingElse and see the custom 404 error site
6. Run curl http://localhost:8080/service-1 to see that the request is redirected to the container called "service-1"
7. Run curl http://localhost:8080/service-2 to see that the request is redirected to the container called "service-2"
8. Run curl http://localhost:8080/service-12 to see that the /static/service-12/index.html file is shown
9. Run docker compose down service1 and curl http://localhost:8080/service-1 to see a 502 Bad Gateway error.
