Pod restarti sonrasi volume kayboluyor

Container | Sanallaştırma Kubernetes

Selamlar,
Ilginc bir sorunla karsilastim. AKS’de asagidaki deployment.yaml’i yukledikten 2-3 dk sonra pod restart ediyor ve volume’lar kayboluyor! “pod description” ve “deployment description” ile kontrol ettigimde garip bir bicimde volume tanimlarinin silindigini goruyorum. Halbuki pod restart etmeden onceki 2-3 dk oncesinde kontrol ettigimde bu tanimlari goruyorum. Pek cok sey denedim ama sorunu cozemedim. Sorun nerede olabilir?

Bu cluster üzerinde aks policy ile herhangi bir kısıtlama yapılmış mıdır?
