 ### 2.3 Docker Architecture
 
-The `Dockerfile` uses a three-stage build:
+The `Dockerfile` now provides two image paths:
 
-1. **WebUI build stage**: `node:20` image, runs `npm ci && npm run build`
-2. **Go build stage**: `golang:1.24` image, compiles the binary
-3. **Runtime stage**: `debian:bookworm-slim` minimal image
+1. **Default local/dev path (`runtime-from-source`)**: a three-stage build (WebUI build + Go build + runtime).
+2. **Release path (`runtime-from-dist`)**: CI first creates `dist/ds2api_<tag>_linux_<arch>.tar.gz`, then Docker directly reuses the binary and `static/admin` assets from those release archives, without running `npm build`/`go build` again.
+
+The release path keeps Docker images aligned with release archives and reduces duplicate build work.
 
 Container entry command: `/usr/local/bin/ds2api`, default exposed port: `5001`.

 ### 2.3 Docker 架构说明
 
-`Dockerfile` 使用三阶段构建：
+`Dockerfile` 提供两条构建路径：
 
-1. **WebUI 构建阶段**：`node:20` 镜像，执行 `npm ci && npm run build`
-2. **Go 构建阶段**：`golang:1.24` 镜像，编译二进制文件
-3. **运行阶段**：`debian:bookworm-slim` 精简镜像
+1. **本地/开发默认路径（`runtime-from-source`）**：三阶段构建（WebUI 构建 + Go 构建 + 运行阶段）。
+2. **Release 路径（`runtime-from-dist`）**：CI 先生成 `dist/ds2api_<tag>_linux_<arch>.tar.gz`，再由 Docker 直接复用该发布包内的二进制和 `static/admin` 产物组装运行镜像，不再重复执行 `npm build`/`go build`。
+
+Release 路径可确保 Docker 镜像与 release 压缩包使用同一套产物，减少重复构建带来的差异。
 
 容器内启动命令：`/usr/local/bin/ds2api`，默认暴露端口 `5001`。
