# ==================================================
# OCDP Backend - Docker Compose 统一配置
# ==================================================
# 使用方式:
#
#   1. 只启动依赖服务 (PostgreSQL) - 开发模式
#      docker compose up -d
#      然后在本地运行: go run cmd/api/main.go
#
#   2. 启动完整服务 (PostgreSQL + Backend)
#      docker compose --profile backend up -d
#
#   3. 启动 Mock 模式 (无需数据库)
#      docker compose --profile mock up -d
#
#   4. 启动数据库管理工具 (可选)
#      docker compose --profile tools up -d
#
# 停止服务:
#   docker compose down
#
# 查看日志:
#   docker compose logs -f
