How to Build and Run Node Apps with Docker and Compose
summary
Shows how to build a small Node image using an Alpine Node base (notes on musl vs glibc), chain RUN instructions to minimize layers, and copy package.json first to avoid rebuilding node_modules. Uses Docker build/run and Docker Compose with a named volume for node_modules and MongoDB service, adds nodemon for live reloads and a wait-for wrapper (netcat) to delay DB connections. Demo builds, creates sharks in the app, and after compose down/up the Mongo volume persists the data.
