# docker-compose.prod.yml – Configurazione PRODUZIONE
#
# Differenze rispetto a docker-compose.yml (sviluppo):
#   - Backend: uvicorn con N worker, senza --reload, senza volume mount
#   - Frontend: build statica servita da nginx (niente Vite dev server)
#   - Porte DB, Redis, MinIO NON esposte sull'host (solo rete interna)
#   - Tutte le credenziali lette da .env (obbligatorie)
#   - MinIO console disabilitata (porta 9001 non esposta)
#   - GreenMail e pgadmin esclusi
#   - Healthcheck ottimizzati per produzione
#
# Utilizzo:
#   docker compose -f docker-compose.prod.yml up -d
