Multi-Container Applications with Docker Compose
summary
Demonstrates using Docker Compose to reproduce production stacks locally with concrete examples: a two-service Python web app calling another service, and a multi-container web app plus Postgres initialized via a mounted volume so the database is ready at startup. Covers splitting configs and using override compose files to expose ports for local development, lifecycle commands (docker-compose up/run/down --rmi --volumes) to start, run one service, and fully clean, and using PROJECT_NAME to run multiple isolated stacks concurrently.
