haproxy

I have had a repository for learning and practicing 'nats' then I started thinking about what the difference is
between different technologies for load balancing.The biggest difference is that technologies like 'nats' and
'rabbitmq' are used to dispatch jobs inside a project to different workers but technologies like 'nginx' and 'haproxy'
are used to dispatch incoming http requests to different servers. In this repository I want to learn how to use 'haproxy' to balance http traffic.

How to use haproxy

Using haproxy is super simple regardless of the language of backend here I have an easy code in golang and then added
haproxy.
My code creates an endpoint and with every get request it just sleeps 5 seconds and then says hi.

then we need haproxy itself, I use docker-compose to run it

Haproxy needs a config file called haproxy.cfg that I show later, the point I want to mention in here is that since
I have used docker-compose to run haproxy I vae to mount the haproxy.cfg file as shown in the screenshot

Here is my haproxy.cfg file
