Последовательное обновление Kubernetes не работает

У меня есть 2 установки Kubernetes для разных проектов, которые, насколько я могу судить, имеют эквивалентную конфигурацию в важных областях, но 2 по-разному выполняют скользящие обновления.

Оба были установлены на AWS с помощью kops.

Система 1 (k8s v1.7.0) - Убить модуль при развертывании с использованием веб-интерфейса k8s, сначала создается новый модуль, а затем после запуска старый модуль завершается. Без простоев.

Система 2 (k8s v1.8.4) - Убить модуль при развертывании с использованием веб-интерфейса k8s, старый модуль немедленно уничтожается, а затем создается новый модуль. Вызывает кратковременный простой.

Есть какие-либо предложения или идеи относительно того, почему они ведут себя по-другому и как я могу заставить систему 2 создать новый модуль перед завершением работы старого?
