Load Balancer project

This project is a simple Load Balancer composed by:

HaProxy
FastAPI
Docker
K6 (to run load tests)

What I'm going to find here?

This project builds up a Load Balancer (HaProxy) and HTTP APIs.
The HaProxy has up to 9 APIs.
The docker-compose file that will set up the LB and 5 APIs (by default).
A file (scripts/instance_commands.sh) which is meant to start/stop each application individually.
