Docker Deployment

This walks you through containerizing Node.js apps with Docker, from basic Dockerfiles to multi-stage builds and production deployments. You'll learn how to set up Docker Compose for multi-container stacks with Postgres and Redis, optimize images down from 1GB to 180MB using Alpine, and handle the gotchas like proper signal handling and non-root users. The progression makes sense: start with a simple container, move to compose files, then tackle CI/CD with GitHub Actions. Honestly, the multi-stage build pattern shown here should be your default. If you're still deploying Node apps without containers or your Docker setup is just copy-pasted from Stack Overflow, this gives you the full picture.
