# 📝 NOTAS
# ============================================
#
# 1. Variables de entorno:
#    - Crear archivo .env con API_KEYS, BEARER_TOKENS, DB_PASSWORD
#
# 2. Certificados SSL:
#    - Generar con certbot antes de iniciar Apache
#    - Montar volumen /etc/letsencrypt
#
# 3. Networking:
#    - app (4300) solo accesible desde apache
#    - apache (80/443) expuesto al host
#    - database (5432) solo en red interna
#
# 4. Escalado horizontal (futuro):
#    docker-compose up -d --scale app=3
