- Created docker-compose.yml with backend and frontend services
- Backend: Node.js API on port 3000 with SQLite volume persistence
- Frontend: nginx on port 8080 with health checks and restart policies
- Configured nginx to proxy /api/* requests to backend service
- Updated frontend API client to use relative URLs (/api instead of http://localhost:3000/api)
- Added Vite dev server proxy for local development workflow
- Implemented health checks for both services with service dependency
- Created comprehensive documentation in docs/docker-compose.md
- Verified: docker-compose.yml syntax is valid YAML
Next step: Test local deployment (docker compose up)
