# ============================================
# Docker Compose para DESARROLLO - NexFit365
# ============================================
# 📁 Carpeta: /srv/mykaizenfit/dev/
# 
# ⚠️ ESTE ARCHIVO ES PARA DESARROLLO con servicios y datos aislados de producción
# 
# COMANDOS:
#   Iniciar:  COMPOSE_PROJECT_NAME=mykaizenfit-dev docker compose -f docker-compose.dev.yml up -d
#   Detener:  COMPOSE_PROJECT_NAME=mykaizenfit-dev docker compose -f docker-compose.dev.yml down
#   Logs:     COMPOSE_PROJECT_NAME=mykaizenfit-dev docker compose -f docker-compose.dev.yml logs -f
#   Build:    COMPOSE_PROJECT_NAME=mykaizenfit-dev docker compose -f docker-compose.dev.yml up -d --build
#
# PUERTOS DE DESARROLLO:
#   - Frontend: 3001 (prod: 3000)
#   - Backend:  8001 (prod: 8000)
#   - DB:       5434 (prod: 5433)
#
# BASE DE DATOS PARA PRUEBAS:
#   - Backend/Celery usan SIEMPRE la BD local de desarrollo (mykaizenfit_dev)
#   - La BD se puede inicializar desde una copia lógica de producción sin compartir datos en vivo
