Hello guys.
I’m trying to install an application in kubernetes but I’m receiving this error message:
Warning FailedScheduling 96s default-scheduler 0/6 nodes are available: pod has unbound immediate PersistentVolumeClaims. preemption: 0/6 nodes are available: 6 No preemption victims found for incoming pod…
I appreciate any suggestions
Kind regards Ciro
