Caddy is a reverse proxy. It will automatically provision HTTPS certificates and generally make your life a lot easier when you're trying to host a new service.

It is run in a Docker container on CSS-mc.

The Caddy container is part of the proxy-apps Docker network. If your new service is in a Docker container, then you should also add it to this network.

Caddy is configured using the Caddyfile. This file is located at /root/caddy-server/Caddyfile. To add a new service, add the following lines:

wiki.cssbham.com {
        reverse_proxy dokuwiki:8080
}

changing wiki.cssbham.com to the host of your new service, and dokuwiki:8080 to the container name and port. Then restart the Caddy container.
