# Docker Compose para Next.js + PostgreSQL
name: openmonetis

# MODOS DE USO:
# 1. Banco LOCAL (PostgreSQL em container):
#    - Configure DATABASE_URL com host "db" no .env
#    - Execute: docker compose up
#
# 2. Banco REMOTO (ex: Supabase, Neon, etc):
#    - Configure DATABASE_URL com a URL do banco remoto no .env
#    - Execute: docker compose up app (apenas o serviço app)
#
# 3. Para parar todos os serviços:
#    - Execute: docker compose down
#
# 4. Para remover volumes (CUIDADO: apaga dados do banco local):
#    - Execute: docker compose down -v
