# ============================================
# 使用说明
# ============================================
#
# 基本使用:
#
# 1. 首次使用前，配置环境变量:
#    cp .env.example .env
#    vi .env  # 修改 DATA_DIR 等配置
#
# 2. 创建数据目录:
#    mkdir -p ${DATA_DIR}/{data,logs,config,temp,redis,nginx}
#
# 3. 启动核心服务:
#    docker-compose up -d
#
# 4. 启动所有服务（含 Nginx）:
#    docker-compose --profile nginx up -d
#
# 5. 启动所有服务（含 PostgreSQL）:
#    docker-compose --profile postgres up -d
#
# 管理命令:
#
# 查看日志:
#   docker-compose logs -f vnpy
#
# 停止服务:
#   docker-compose down
#
# 重启服务:
#   docker-compose restart vnpy
#
# 进入容器:
#   docker-compose exec vnpy bash
#
# 更新并重启:
#   docker-compose up -d --build
#
# 数据备份:
#   tar czf vnpy_backup_$(date +%Y%m%d).tar.gz ${DATA_DIR}
