NGINX 在 Dockered Django 项目（Nginx、Django、Docker）中找不到媒体文件

Question

问题

我正在运行一个由Nginx 在Docker container 中提供服务的Django 应用程序，当我尝试访问管理中上传的一些资源时，这些资源将存储在media 文件夹中，他们给出我是404 error，只有当我使用 Docker 运行应用程序时才会发生这种情况，因为如果我使用 python manage.py runserver 运行应用程序，媒体文件将正常提供。

我有什么

问题在于 nginx.conf 和 urls.py 路径配置不一致。您有两种选择：

1. 更新 urls.py

   urlpatterns += static(settings.MEDIA_URL,
                 document_root=settings.MEDIA_ROOT)
   

2. 更新 nginx.conf

     # app media uploaded files
