+
+> How to deploy. Build, push, restart, rollback.
+
+## Architecture
+- Container: Docker
+- Image registry: local (Talos)
+- Orchestration: docker-compose on Talos
+- Reverse proxy: nginx on Talos
+- Auto-deploy: forgejo webhook → Talos deploy script
+
+## Deploy
+
+### Automatic (CI/CD)
+On merge to `main`:
+1. forgejo webhook fires
+2. Talos deploy script pulls latest commit
+3. Rebuilds Docker image
+4. Stops old container, starts new
+5. Runs health check
+6. Rolls back on failure
+
+### Manual
+```bash
+ssh netcup
+cd /srv/pryscraper
+git pull origin main
+docker build -t pryscraper:latest .
+docker stop pryscraper
+docker rm pryscraper
+docker run -d --name pryscraper --restart unless-stopped --network host -p 8005:8005 pryscraper:latest
+```
+
+## Health Check
+```bash
+curl -fsS http://localhost:8005/health
+```
+
+## Rollback
+```bash
+ssh netcup
+cd /srv/pryscraper
+git log --oneline -5   # find last good commit
+git checkout <commit-hash>
+docker build -t pryscraper:latest .
+docker restart pryscraper
+```
+
+## Logs
+```bash
+docker logs pryscraper --tail 100 -f
+```
+
+## Monitoring
+- Prometheus: `/metrics` endpoint
+- Grafana: dashboards in fleet-infra
+- Loki: log aggregation
+
+## Secrets
+All secrets in gopass:
+- `rmi/pryscraper/admin_key`
+- `rmi/pryscraper/db_password`
+- _see AGENTS.md for full list_
+
+Loaded via docker `--env-file` or systemd `EnvironmentFile`.
+
+## Firewall
+- Public: 80, 443 (nginx)
+- Internal: 8005 (localhost only, behind nginx)
+- Tailscale: 8005 for admin access
+
+## Backup
+- Code: forgejo (source of truth) + Hydra bare mirror (daily 04:00)
+- Data: DB snapshot to R2 (daily)
+- Config: gopass
