运行Django＆＃x2B; PostgreSql＆＃x2B;使用compose -File许可错误在Docker容器中的Gunicorn

Question

我正在使用docker-desktop版本20.10.16在Ubuntu 20.0.4 Lts上

我想dockerise django（v3.2），PostgreSQL（v14.3）和Gunicorn（v20.1.0）（v20.1.0）（v20.1.0）。并将这些容器用作由我本地计算机上运行的单个NGINX实例服务的虚拟主机。

我能够构建图像和一个容器，但是设置Django应用程序失败了，因为在创建/写入myporoj.log时会出现文件错误 我目前是，不使用nginx作为虚拟主机的代理服务器 - 我希望o在继续使用Nginx与我的设置中使用Nginx之前先解决此ISSE。

以下是其他相关详细信息：

我的文件结构（在本地计算机上）如下：

/path/to/myprojectweb/
            /myproj
               /myproj
               settings.py 
               wsgi.py
               # etc.
           Dockerfile.prod
           compose.prod.yml

dockerfile.prod.yml

- 虽然我可以使用所需文件夹的权限（甚至在适当的情况下设置粘性标志） - 我仍然有文件许可错误，而gunicorn也barfs barfs barfs基因找不到wsgi.py

如何修复文件错误权限问题，还要让Gunicorn运行（使用我通过CL标志传递给它的配置数据？）
