# ─────────────────────────────────────────────────────────
# Docker Compose - Stack completa para testar eBPF Sockmap
#
# Serviços:
#   nginx     → Proxy reverso (porta 80 → Node.js)
#   app       → Servidor Node.js (porta 3000)
#   mysql     → Banco de dados MySQL (porta 3306)
#   postgres  → Banco de dados PostgreSQL (porta 5432)
#
# Todos os containers ficam na mesma rede bridge,
# e o eBPF sockmap acelera a comunicação entre eles.
