Я использую этот шаблон развертывания (так он называется?).Две капсулы работают, но две застряли на сдерживании.Если я масштабируюсь до 2-х реплик, то 1 работает, а 1 застревает при обработке содержимогоКак запустить все 4 модуля?
Это объявление создает PV в AWS и присоединяет ПВХ.Данные постоянны.Но не смог обойти проблему сдерживания.
$ kubectl get pods
