Building a Production Grade AWS Infrastructure Project (Part 2): Containerization

Short summary

Part 2 of a production AWS infrastructure series, this post covers containerizing a full-stack note-taking app. The backend uses a slim Node image with production-only dependencies, while the frontend uses a multi-stage build with Nginx for static file serving. Docker Compose orchestrates frontend, backend, and Postgres with health checks and shared networking.

• •Backend Dockerfile uses node:22-slim for sqlite3 compatibility with npm ci --omit=dev
• •Frontend uses multi-stage build: Node for building, Nginx for serving static files
• •Docker Compose ties services together with health checks and shared app-network
