+## 国内镜像加速（部署）
+
+- **容器基础镜像**：默认使用 `docker.m.daocloud.io/library/...`（DaoCloud Docker Hub 代理）。若你所在网络下该源慢或失败，可将三处前缀统一改为 `docker.1ms.run/library` 或 `dockerproxy.cn/library`（后者偶发 EOF 时可换源）。
+- **Python / npm / apk**：构建时已分别使用清华 PyPI、npmmirror、阿里云 Alpine 源（见各 `Dockerfile`）。
+- **本机 Docker 守护进程（可选）**：仍从 Docker Hub 拉取其它镜像时，可在 Docker Desktop → Settings → Docker Engine 中配置 `registry-mirrors`，例如：
+
+```json
+{
+  "registry-mirrors": [
+    "https://docker.m.daocloud.io",
+    "https://docker.1ms.run",
+    "https://dockerproxy.cn"
+  ]
+}
+```
+
+保存并重启 Docker 后生效。
+
 ## 一键启动
 
 确保本机已安装 Docker Desktop，然后在项目根目录执行：
