 # 制作PHP8.1版的workerman环境镜像
 
+## 说明
+
+用本文方法制作的镜像不是跨平台的，也就是说在amd64平台制作的镜像只适用于amd64平台，在arm64平台制作的镜像则只适用于arm64平台。

 ## 拉基础镜像
 
 ```sh
-docker pull php:8.1-cli
+docker pull php:8.1-cli-bullseye
 ```
 
 ## 启动容器
 
 ```sh
-docker run -itd --net=host --name=workerman php:8.1-cli
+docker run -itd --net=host --name=workerman php:8.1-cli-bullseye
