В настоящее время я экспериментирую с кухонными ножницами. Я создаю шаблон для Django, который работает. Следующий шаг-добавить для него контейнер docker. По какой-то причине я получаю следующую ошибку при запуске docker-compose up (или просто запускаю приложение django вручную из контейнера):

 app_1  | Exception in thread django-main-thread:

Когда я запускаю приложение django вручную, все работает просто отлично.
Я также добавлю свой файл Dockerfile и свой файл docker-compose.yaml:

Кто-нибудь знает, откуда берется ошибка и/или как ее исправить?

Заранее спасибо!
