docker-compose-dev

To set up a local multi-service stack with Docker Compose, you need a working docker-compose.yml, an .env template for credentials, and startup verification steps. The stack orchestrates your app and a real database backend like PostgreSQL to mirror production behavior.

Reproducing production database connectivity issues during local development requires a Docker Compose stack with a real PostgreSQL backend. This approach wires up service interdependencies and health checks to deterministically mirror production behavior for debugging.

Yes, you need a .env file to run database migrations with Docker Compose. You must copy the .env.example template to .env and edit the credentials as needed before bringing up the stack and running optional migrations and seeds.

Yes, Docker Compose can enforce a deterministic startup order for an app and PostgreSQL database. The configuration supports health checks and service interdependencies to ensure the database backend is ready before the application starts.

You should use Docker Compose instead of a mock database when you need a real PostgreSQL backend to reproduce production behavior during integration testing, debugging, or onboarding with a reproducible local environment.
