 - 镜像 `pip install -r requirements.txt`（PyPI）+ 基础镜像 `python:3.13.11-slim`（Docker registry；Dockerfile 已注明内网无 dockerhub 时需本地预先存在该镜像）。
 - 离线重建可选做法：内网 PyPI/npm 镜像源，或预下载 wheels + `pip install --no-index --find-links`、`npm ci --offline`。

+## 2026-08-05：部署第二套独立 CapacityReport 实例
+
+- 新增 `packaging/docker-compose.capacityrepost.yml`，只编排 Web 与 MySQL：容器名固定为 `capacityrepost-web`、`capacityrepost-mysql`。
+- Web 发布宿主机 `19082` 到容器 `9081`；MySQL 只 `expose 3306`，不发布宿主机端口，数据导入导出统一走 Web。
+- 两个容器仅加入显式桥接网络 `capacityrepost-network`；运行数据使用独立命名卷 `capacityrepost-web-data`、`capacityrepost-mysql-data`，不复用旧实例资源。
+- Web 首次启动通过 `DB_HOST=capacityrepost-mysql` 写入新数据卷内的 `Configure.json`；MySQL 初始化独立的 `CapacityReport`、`celldata` 数据库。
+- 当前代码镜像使用不可变标签 `capacityrepost-web:a66ce4c`，服务器部署目录为 `/opt/capacityrepost`。健康检查 `GET /health` 已验证应用与 MySQL 均正常，首页可访问。
+- 同机旧实例 `capacity-report-app`（19081）与 `capacity-mysql`（13306）是受保护资源；部署第二实例时禁止对旧容器执行停止、重建、改名、改网络、改卷或 compose down。
