This container runs a simple lightweight Python HTTP file server for files.charlesreid1.com.
Here's the one-liner:
python3 -m http.simple -b <docker-ip> -p <port>
This binds to the docker network and listens for requests on a port. Requests for files.charlesreid1.com are reverse-proxied by the nginx frontend (see d-nginx-charlesreid1) and passed along to the internal docker network.
