The computers must burn.
This page contains general configuration details in all horrific machines; for machine-specific configuration, see Hardware.
Any new hosting user will have an account that can ssh onto our machines with limited access; a console/dashboard will automate most functionality - creating docker containers (which can then be ssh'd into with full access), exposing ports of a docker container, linking to domains (reverse proxy through nginx), creating/uploading SSL certs, etc.
The "horrific" CLI in this repo will manage most of these features, as well as providing an admin CLI & monitoring functionality to keep track of resource usage.
