Infrastructure

Docker Compose stack for the AFK bot and portfolio site. Runs on a single VPS with automatic HTTPS via Caddy and Let's Encrypt.

Services

Service	Description
caddy	Reverse proxy, handles TLS termination
grafana	Dashboards and log explorer
prometheus	Metrics scraping from afkbot :9090
loki	Log aggregation
promtail	Reads Docker container logs and ships to Loki
afkbot	Mineflayer AFK bot managing 16 accounts
landing-page	Next.js portfolio site

Prerequisites

• Docker and Docker Compose installed on the VPS
• DNS A records pointing to the VPS IP:
  • williamedwards.me
  • grafana.williamedwards.me

Setup

1. Clone all three repos alongside each other:

~/
  afkbot/
  infrastructure/
  landing-page/

2. Create a .env file in this directory:

DOMAIN=williamedwards.me
GRAFANA_PASSWORD=changeme
ADMIN_PASSWORD=changeme

3. Start the stack:

docker compose up -d

4. On first run, copy Microsoft auth tokens into the persistent volume so bots don't need to re-authenticate:

cp -r /root/.minecraft/nmp-cache/ /var/lib/docker/volumes/infrastructure_auth_cache/_data/

Useful commands

# View logs for a service
docker compose logs -f afkbot

# Rebuild and restart a single service
docker compose up -d --build landing-page

# Restart everything
docker compose restart

# Stop everything
docker compose down

Volumes

All state is stored in named Docker volumes so it survives container restarts and VPS reboots:

• caddy_data — TLS certificates
• grafana_data — dashboards and data sources
• prometheus_data — metrics (30-day retention)
• loki_data — logs
• auth_cache — Microsoft OAuth tokens for the bots (/root/.minecraft)
