# Production overlay — adds TLS (Caddy auto-HTTPS), enforces auth, and sets restart policies.
# Layer it on top of the base compose:
#
#   DOMAIN=app.example.com docker compose -f docker-compose.yml -f docker-compose.prod.yml \
#       --profile full up -d --build
#
# Requires: a VM with Docker, a DNS A record for $DOMAIN pointing at it, and ports 80+443 open.
# Lock the rest down with a firewall (e.g. `ufw allow 80,443/tcp` and deny 8000/8080/5432/9000).

# Fail-closed datastore credentials, shared by every service that opens the database or the object
# store. This is an anchor rather than two copies because the API and the job worker MUST fail closed
# in the same way: the worker inherits the base compose's permissive `${POSTGRES_PASSWORD:-bim}`
# unless something overrides it here, so a copy that drifted would leave the worker connecting with
# the dev default password in production while the API refused to start — and only the API's refusal
# would be visible.
