# =============================================================================
# 企微IT智能服务台 — 本地开发环境 Docker Compose
# =============================================================================
# 目标:本地电脑(Windows + Docker Desktop)
# 用途:开发 + 测试,不依赖企微 OAuth,代码 volume mount 自动 reload
# 用法:
#   1. cp .env.example .env.dev (编辑填值,或直接用 .env.dev 模板)
#   2. docker compose -f docker-compose.dev.yml up -d
#   3. 前端 4 端各跑 pnpm dev(Vite proxy /api → backend:8000)
# 启动后:
#   - Backend:  http://localhost:8000  (Swagger: /docs)
#   - Postgres: localhost:5432
#   - Redis:    localhost:6379
# =============================================================================
