Причина сбоя: Поскольку WebApplicationFirewall не поддерживается для стандартного уровня AppGateway, шаблон VALIDATION завершится ошибкой, даже если для параметра enabled установлено значение false, поскольку при проверке ключ "webApplicationFirewallConfiguration" сам по себе недопустим для стандартного уровня.
Исправление: Использование вложенных шаблонов для создания дочернего развертывания шаблона шлюза приложений без «webApplicationFirewallConfiguration», если брандмауэр отключен, в противном случае - с «webApplicationFirewallConfiguration», если брандмауэр включен вместе с брандмауэром.значение режима в файле параметров.
Рабочий пример: Ниже приведен корневой шаблон для развертывания, а также два шаблона с включенным и отключенным межсетевым экраном.Затем он имеет два файла параметров - один для включенного брандмауэра и другой для отключенного.
Чтобы опробовать этот пример, выполните следующие действия:
- Загрузите два дочерних шаблона вхранилище BLOB-объектов.
- Создайте этот контейнер BLOB-объектов, в который загружаются шаблоны, доступны для общего доступа или используйте токен SAS при создании URL-адреса шаблона.
- Обновите переменные "appGatewaysTemplateWaffalse" и "appGatewaysTemplateWaftrue" в корневом каталоге.шаблон с URL-адресами загруженных дочерних шаблонов.
- Go https://portal.azure.com/#create/Microsoft.Template -> «Создайте собственный шаблон в редакторе».
- Используйте этот обновленный корневой шаблон с URL-адресами и файлом параметров(включен или отключен) по желанию.
Корневой шаблон (VNet + дочернее развертывание):
