Caddy Proxy

This container will serve as a reverse proxy available for every container plugged in caddy network.

Image we have a web project called web-project. This project uses 2 services, Nginx and PHP-FPM. We can have a docker-compose in which these services are defined. This project need a database. Instead of adding a service inside or project we can use a Pgsql external container and use it. This way, instead of having many web projects with a new database each time, we use only one container for all of them.

In our Caddy container we will be able to assign domain names to our containers. Our project will be available on our host with web-project.localhost and the database will be available with, for example, database.localhost. Both containers will share a common network (caddy network) and caddy will help by making them easily available.

Caddy and Database are only on caddy network while web-project has it's own and caddy network too.
