-这会产生一个 **`154KB +`** 的单层镜像。 如果您需要以不同的方式配置 `httpd`，您可以覆盖 CMD 行：
-
-```dockerfile
-FROM lipanski/docker-static-website:latest
-COPY . .
-
-CMD ["/busybox", "httpd", "-f", "-v", "-p", "3000", "-c", "httpd.conf"]
-```
-
-缩小镜像过程[查看原文](https://lipanski.com/posts/smallest-docker-image-static-website)，镜像 [Dockerfile 源码](https://github.com/lipanski/docker-static-website)。
+使用多阶段构建能将构建依赖留在 builder 镜像中，只将编译完成后的二进制文件拷贝到运行环境中，大大减少镜像体积。
