我得到这个错误：

/run.sh: 3: cd: can't cd to /var/www

但是，当我运行一个交互式shell时，我可以看到我的当前目录是/var/www。

这是我的dockerfile：

FROM php:8.1.0-fpm

这是我的www.example.com的内容run.sh:

#!/bin/sh

cd /var/www

php artisan cache:clear
php artisan route:cache

/usr/bin/supervisord -c /etc/supervisord.conf

正如你所看到的，我正在尝试运行一个php laravel应用程序。我不知道为什么会发生这种情况，我会很感激任何想法来解决这个问题。谢谢你
PD：这是www.example.com的权限run.sh，它位于我的laravelapp的docker/目录中：

ls -ldh /var/www/

输出：
