Итак, у меня есть докеризованное приложение Django, работающее с uWSGI и NGINX, управляемое супервайзером (поэтому оба они запускаются в одном контейнере). Он отлично работает и отлично работает при локальном запуске, но когда я развертываю его в веб-приложении Azure для контейнеров, он не отвечает на http-запрос на прогрев.

Я пробовал выполнять различные настройки портов в Azure/в приложении, но, похоже, ничего не работает.

Настройка, которую я пробовал, такова:

• NGINX предоставляет приложение в порту 80, добавляя конфигурацию на портале Azure с портом=80
• NGINX предоставляет приложение в порту 8000, добавляя конфигурацию на портале Azure с портом=80 и WEBSITES_PORT=8000
• В обоих случаях в файле Dockerfile отображаются как 80, так и 8000
• Увеличьте лимит времени ожидания для приложения до 1800 секунд

Но я все еще получаю ту же ошибку, и я действительно чувствую, что не знаю, куда идти дальше. Кто-нибудь может помочь мне разобраться в этом?

Я опубликую журналы и соответствующие файлы ниже. Как вы можете видеть в журналах, супервизор, похоже, запускается, но не дает ответа, который, по-видимому, необходим Azure для запуска сервера.
