Django +错误500。长邮政

Question

目前，我正在尝试将Django应用程序准备好进行部署。我试图通过使用docker、dockerfile和uwsgi创建我的应用程序的映像来对我的应用程序进行“坞化”。我可以使用以下命令来完成这一任务：

sudo docker create --name container --network network --network-alias container -t -p 40001:8001 image_name 

docker build -t image_name .

图像生成，我可以启动它，我可以访问容器应用程序的主页。然而，当我试图导航到应用程序中的其他页面时，我得到了一个Server错误(500)，在控制台(Firefox)中，我得到了这个错误：

 The character encoding of the HTML document was not declared. The document will render with garbled text in some browser configurations if the document contains characters from outside the US-ASCII range. The character encoding of the page must be declared in the document or in the transfer protocol.

我的base.html里有这个

<meta content="text/html; charset=utf-8" http-equiv="Content-Type">
    <meta content="utf-8">

每个网页都扩展了这个页面。

我相信这可能是我的静态文件配置的一个问题，因为我正在使用WhiteNoise。但是我对我的dockerfile和uwsgi.ini文件有问题。

发现我试图连接到一个不同名字的数据库。检查我的数据库容器和应用程序容器的日志，以找出这一点。
