Docker Container Infrastructure

This repository details all of the underlying production infrastructure for databases, reverse proxies, and administration tools that the coursetable abstracts away.

The infrastructure is currently designed to provision on a monolithic VM. However, it is configuration-agonistic. Its pure dependencies are docker and docker compose. Please see deployment.md for instructions on how to bootstrap a new server.

Each directory denotes a separate Docker Compose configuration, each with its own network.

Below is the list of every network and its attached services (including those defined in coursetable):
