 # 1. 从git拉取最新代码

 # 3. 构建前端dist
-# 4. 制作Docker镜像
+# 4. 制作Docker镜像（支持基础镜像和应用镜像）
 # 5. 保存镜像到文件（用于离线部署）
+#
+# 使用方法：
+#   ./build.sh [target] [options] [version]
+#
+# 目标(target)：
+#   base-serv  - 构建后端基础镜像（包含Python依赖）
+#   base-web   - 构建前端基础镜像（Nginx）
+#   base-all   - 构建所有基础镜像
+#   serv       - 构建后端服务镜像
+#   web        - 构建前端服务镜像
+#   mysql      - 构建MySQL镜像
+#   all        - 构建所有应用镜像（默认）
+#
+# 选项(options)：
+#   build      - 编译代码（serv和web需要）
+#   save       - 保存镜像到tar文件（需要指定version）
+#
+# 版本(version)：
+#   save=YYYYMMDD_HHMMSS  - 指定要保存的镜像版本
+#   不指定则使用当前构建的版本
+#
+# 示例：
+#   ./build.sh base-all                          # 构建所有基础镜像
+#   ./build.sh serv build save                   # 编译后端+构建镜像+保存当前版本
+#   ./build.sh all build save                    # 完整构建流程
+#   ./build.sh serv save=20251124_143025         # 保存指定版本的镜像
+#   ./build.sh all build save=20251124_150000    # 构建并保存为指定版本

-校园新闻管理系统 - Docker镜像部署说明
-========================================
-
-构建信息:
-  构建时间: $(date '+%Y-%m-%d %H:%M:%S')
-  版本号: ${IMAGE_VERSION}
-  构建主机: $(hostname)
-  Git分支: $(git branch --show-current 2>/dev/null || echo "未知")
-  Git提交: $(git rev-parse --short HEAD 2>/dev/null || echo "未知")
-
-镜像文件:
-  MySQL镜像: ${MYSQL_IMAGE_FILE}$([ -f "${MYSQL_IMAGE_FILE}.gz" ] && echo ".gz")
-  后端镜像: ${SERV_IMAGE_FILE}$([ -f "${SERV_IMAGE_FILE}.gz" ] && echo ".gz")
-  前端镜像: ${WEB_IMAGE_FILE}$([ -f "${WEB_IMAGE_FILE}.gz" ] && echo ".gz")
-
-========================================
-部署步骤:
-========================================
-
-1. 将镜像文件传输到目标服务器
-
-2. 解压镜像文件（如果已压缩）:
-   gunzip ${SERV_IMAGE_FILE}.gz
-   gunzip ${WEB_IMAGE_FILE}.gz
-
-3. 加载Docker镜像:
-   docker load -i ${MYSQL_IMAGE_FILE}
-   docker load -i ${SERV_IMAGE_FILE}
-   docker load -i ${WEB_IMAGE_FILE}
-
-4. 验证镜像:
-   docker images | grep school-news
-
-5. 启动服务:
-   cd docker
-   docker-compose up -d
-
-6. 查看服务状态:
-   docker-compose ps
-   docker-compose logs -f
-
-========================================
-访问地址:
-========================================
-  前端: http://localhost:8080/schoolNewsWeb/
-  后端: http://localhost:8081/schoolNewsServ
-
-========================================
-注意事项:
-========================================
-1. 确保目标服务器已安装Docker和Docker Compose
-2. 确保端口8080、8081、3306、6379未被占用
-3. 首次部署需要准备数据库初始化脚本
-4. 生产环境请修改默认密码（.env文件）
