How to rationally use traefik+nginx+php-fpm for multiple docker projects?

Question

Nginx

There are 3 different projects. Now they are tied to one nginx (1 instance) + php7.3_apache (3 instances) within the docker framework.

How to correctly (rationally) use one proxy server (in this case, Traefik), in conjunction with php-fpm + nginx?

My suggestion

What solutions do you use for this problem?

Answer 1

The second option is definitely wrong.
You have your own fpm and your compiled code in the fpm image of each application.
The minimum unit is a pair of nginx + fpm, and it will scale (if you implement it). It is for this pair that you create a service for the application (and not two services).
So your first option is a working method, but as simple as possible.
