Frequently asked questions
Where do I put passwords?
In a .env file next to docker-compose.yml (never commit it). The generated compose file reads variables like ${POSTGRES_PASSWORD}.
Why a multi-stage Dockerfile?
Dependencies are built in one stage and only what's needed is copied to a slim final image — smaller, faster and more secure.
How do I keep database data?
Named volumes (e.g. pgdata) are created so data survives container restarts and rebuilds.
