Simplify All the Things with Docker Compose
summary
Demonstrates concrete files and commands: a Compose YAML that replaces repeated docker run calls, a dev image using multi-stage Dockerfile to share dev/prod builds, and a dev workflow using docker-compose up --build plus a mounted node_modules volume. Adds a MySQL service with config files and env vars, fronts services with Traefik reverse proxy, and runs end-to-end tests as a test service that exits to drive CI. All demos run successfully locally.
