Я пытаюсь запустить приложение, предоставляемое на github: https://github.com/dotnet-architecture/eShopOnWeb, и оно отлично работает на моей локальной машине.
Однако, когда я запускаю то же самое на kubernetes, я получаю ошибки для встроенныхSQL-сервер и они с перебоями.Он работал один раз, но перестал работать, даже когда я изменил какой-либо код.
Вот журналы, когда он работает нормально:

Запущенный код + код в Kubernetes взяты из одного и того же образа контейнера (зарегистрированный репозиторий), и оба они - образы Ubuntu.Это просто нестабильность dotnet на докере или я что-то упустил?
