Docker Compose Production-like Stack

Assemble a realistic local environment — Postgres, Redis, RabbitMQ and an app — with health checks, dependency ordering and env config, one service at a time.

Real systems are never one process. Here we build a production-like local stack with docker-compose — Postgres, Redis, RabbitMQ and an app — adding one service or one piece of wiring per step. The focus is the unglamorous glue that makes a stack reliable: health checks, dependency ordering that waits for readiness, centralized config and restart policy. By the end one command brings the whole environment up in the right order.

What you'll build

• Compose Postgres, Redis, RabbitMQ and an app together
• Add health checks so readiness is observable
• Order startup with dependency conditions
• Centralize configuration in an env file
• Make services restart on failure
