Как развернуть приложение aspnetcore в Ubuntu в цифровом океане

/ 15 октября 2019

После публикации моего приложения asp.net core 2.1 в Digital Ocean на сервере Ubuntu, если я ввожу IP-адрес сервера в другом, чтобы открыть приложение в браузере, я получаю эту ошибку:

Служба недоступна Сервер временноневозможно обработать ваш запрос из-за простоя или проблем с емкостью. Повторите попытку позже.

Сервер Apache / версии (Ubuntu) на сервере Server_IP Порт 80

Из этой строки: 

Microsoft.AspNetCore.Identity.UserManager`1.FindByNameAsync(String userName)
at App_name.Data.ApplicationDbContext.CreateAdminAccount(IServiceProvider serviceProvider, IConfiguration configuration) in Data\ApplicationDbContext.cs:line

Когда я запускаю приложение локально, я проверяю, еслипользователь не существует, тогда CreateAdminAccount создает пользователя-администратора.

Я уверен, что приложение не может выполнить никаких миграций до запуска приложения другим пользователем для создания пользователя-администратора.

Я хочу знать, как применитьмиграция в базу данных при запуске приложения.

Если я проверяю журналы приложения, я тоже получаю эту ошибку:
