TODO

Update Readme (CI, Git, plantuml, etc.)
Split docker/web/docker-compose.yaml into different configs (e.g. web, gitlab, drone) using the same network
Use /var/lib/pbri/docker/... instead of Docker volumes (makes backups easier)
- Make it inaccessible to anyone but root (-rw------)
Add Drone runner
Figure out how to dependably store .env files (Ansible vault? Something else?)
