How to properly organize multiple nginx virtual hosts in Docker?

Question

Nginx

From docker's point of view, each process is a separate container.
1. Does this mean that each individual site should run in a separate container?
2. If item 1 is yes, then how to scatter between these containers the users of the control machine that are hollowed out on 80/443 ports?
3. If there is no item 1, then how to properly separate the automated integration of applications?

Answer 1

Each application can be run in a separate application, or in one, a matter of taste. The problem is that all applications want 80/443 port.
To solve this problem, you can start one container with nginx and configure it as a reverse proxy, i.e. it will take ports and scatter requests across containers based on the host address.
I can recommend a ready-made image for this https://github.com/jwilder/nginx-proxy

Answer 2

Nothing prevents you from having one container with nginx and one container per site.
