 Clone repo to /opt/apps/rfiles-online on Netcup, create .env with DB_PASSWORD/REDIS_PASSWORD/SECRET_KEY, run docker compose -f docker-compose.prod.yml up -d --build, verify migrations and health endpoint. Add DNS records (rfiles.online + *.rfiles.online CNAME to tunnel) and hostname to Cloudflare tunnel config.

+Deployed to Netcup at /opt/apps/rfiles-online. Fixed celery-beat crash (read-only filesystem) by redirecting schedule file to /tmp tmpfs. All 5 containers running: rfiles-api (healthy), rfiles-db (healthy), rfiles-redis (healthy), rfiles-celery-worker, rfiles-celery-beat. Traefik labels configured for rfiles.online, www.rfiles.online, and direct.rfiles.online.
