Reverse Proxy

The server is setup with a reverse proxy that uses automatic configuration to set the forwarding of the sub domain to the correct docker instance rathr than manually needing configured. This is based on the following docker file https://github.com/nginx-proxy/nginx-proxy.git and the setup process is detailed here

Web Servers

Each webserver with the exception of discourse is based on https://github.com/sprintcube/docker-compose-lamp/tree/7.2.x](https://github.com/sprintcube/docker-compose-lamp/tree/7.2.x) with amended docker-compose.yml files to work with the reverse proxy including removing the mysql, phpmyadmin and redis installs. Each webserver has a .env file which contains certain environment settings.

Each webserver can be connected to via ssh from within Zerocool using the command

docker exec –it container id (run docker-ps to find this) /bin/bash
