У меня есть docker изображение, содержащее. NET Core 3.1 Web API. Он запускает локально и модульные тесты на обоих Docker изображениях в конвейере devops. Он создается и развертывается без ошибок, однако, когда я пытаюсь его запустить, я получаю следующую ошибку. Я вижу, что он должен быть правильно развернут, так как 2-я строка в журнале ниже записывается в файл Program.cs (см. Ниже). Любые идеи о том, как устранить ошибку?
Пожалуйста, потерпите меня, я новичок в Azure и контейнерах. Если вам нужна дополнительная информация о развертывании, дайте мне знать, и я обновлю вопрос.
Заранее спасибо.
