Docker-Composing Your Way to a Better Development Environment
summary
Shows how to replace heavyweight VMs with containerized services by building a Django dev stack with a Dockerfile plus a docker-compose.yml that runs Postgres, Redis and a Celery worker; demonstrates mapping source with volumes, using service hostnames (DB), and commands like docker compose up/down/start/stop/logs/run/exec. Notes tradeoffs: faster provisioning and smaller images (Alpine), but slower large test suites and trickier debugging and volume-data persistence on down.
