Browser

You can access the US (User server) which is considered the entry point for the network application by using the below URL in your browser. Notice that you access the US by referencing the IP address for localhost and not 172.19.0.2 since you're outside of the Docker network.

http://127.0.0.1:8080/fibonacci?hostname=fibonacci.com&fs_port=9090&number=7&as_ip=172.19.0.4&as_port=53533
