Multi-stage Alpine Dockerfile producing a standalone Next.js image with the better-sqlite3 native addon included. Gitea workflow builds on push to main and on v* tags, pushing to the Gitea registry using the REGISTRY_URL variable and REGISTRY_TOKEN secret. Compose file mounts ./data so alerts.db and settings.json persist across restarts. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
