Pod in Deployment не выполняет проверку готовности

Я выполнил простое развертывание модуля nginx, а затем отредактировал развертывание, добавив readinessProbe и livenessProbe через TCP, как в официальные документы.

Как только я сохраню его, развертывание создало новый набор реплик и запустило новый модуль, но тесты никогда не выполняются.

Вот результат развертывания yaml команды describe:

А вот события стручка:

Почему в соединении отказывается, когда я открывал порты со следующими данными?

ports:
  - containerPort: 8080
    protocol: TCP
