Docker文件安装错误的php

Question

我有一个laravel/php docker镜像，我更新到了php 8.1-我现在正试图回到我们的项目7.3版本，但无法工作。

这是我的YAML

这是我的Dockerfile

我已经删除了docker缓存&容器并运行：docker-compose up -d --force-recreate --build

但我确实看到了"；59bf1c3509f3已经存在"；在运行时在构建中。完成后，我有了最新版本的PHP 8.13

那么它可能是另一个我没有清理的缓存吗？或者如何强制安装PHP 7.2 o 7.3

apt是基于Debian的分发的包管理器。使用apk管理Alpine Linux上的软件包。请参阅如何使用此图像。
