Я создал очень простую функцию AzureApp с использованием Visual Studio Code, которая ничего не делает, но регистрирует полученное сообщение (приложение Function прослушивает сообщение Eventhub в Azure). Это работает и хорошо размещается, когда я отлаживаю приложение функции локально. Однако, когда я публикую это в мини-кубе как контейнер, он выдаст ошибку ниже:
The listener for function 'EventHubCSharpFunc' was unable to start.
Microsoft.Azure.WebJobs.Host.Listeners.FunctionListenerException: The listener for function 'EventHubCSharpFunc' was unable to start. ---> Microsoft.Azure.EventHubs.Processor.EventProcessorConfigurationException: Encountered error while fetching the list of EventHub PartitionIds ---> System.Net.Sockets.SocketException: Resource temporarily unavailable

Я попытался проверить, есть ли у моего кластера доступ в Интернет, но я успешно могу пропинговать IP-адрес из других контейнеров в мини-кубе.
