我有一个课堂项目，我在其中创建了docker容器来托管将使用PHP进行后端逻辑的网站。目前，我的NGINX容器已配置为使用PHP-FPM容器作为其PHP处理程序。

我遇到的问题是我实际上在上传视频文件。基本上，当我（网站上的用户）上传视频文件时，使用一个调用PHP代码move_uploaded_file的上传框，可以在PHP容器内的“已上传”文件夹中看到该文件。当我转到NGINX容器时，文件不存在。我不知道是否缺少某种配置选项，将从PHP代码创建的文件镜像到NGINX文件目录？

如果我重新启动容器，该文件现在似乎也将显示在NGINX容器中。问题是，当我尝试通过网站（嵌入标签）查看文件时，返回了403错误。我认为这与PHP上传文件的用户有关吗？

因此，基本上，我可以上载PHP处理程序可以处理的文件。但是我必须重新启动所有容器才能使其显示在Web服务器上。然后，我必须打开一个终端，并弄乱权限，通常给它chmod 777使其发挥作用。我想知道我是否做错了什么？

谢谢，这是一些相关代码。
