У меня есть файл с PV, Service и 2 Pod с сохранением состояния, включая Dynamic PVC.
Когда я развернул файл, возникла проблема с состоянием PVC.
# kubectl get pvc
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
www-web-0 Bound pv-test 10Gi RWO my-storage-class 7m19s
www-web-1 Pending my-storage-class 7m17s
Один из статусов PVC - «Ожидание», а причина - «Имя класса хранения не найдено».
Но один из ПВХ был создан нормально.
Ниже приведено содержимое файла.

Если кто-то знает причину, дайте мне знать.
Заранее спасибо.
