This repository contains an experiment where I set up two sites within Docker containers and nginx acts as a proxy.

Consider running multiple webserver containers on the same server. How does the server know which container to serve to the user?

This project contains a docker-compose.yml file containing three containers. Two websites that serve a webpage via Apache httpd: "Site 1" and "Site 2". The third container is an nginx container acting as a proxy between the two sites.

Within the nginx configuration two sites are defined with two different server names:

• site1.experiment.waltertamboer.nl
• site2.experiment.waltertamboer.nl

Each container runs on a different port (8081 and 8082 in this example). When one of these addresses is entered in the browser, the proxy knows to which container the user should be redirected.

• Clone the repository
• Edit your /etc/hosts file and make sure it contains the following lines:

  127.0.0.1 site1.experiment.waltertamboer.nl
  127.0.0.1 site2.experiment.waltertamboer.nl
  

• Start up the containers: docker-compose up -d

Now you'll be able to visit site 1 and site 2 via the following addresses:

• http:https://site1.experiment.waltertamboer.nl
• http:https://site2.experiment.waltertamboer.nl
