deploying Portainer on Kubernetes Cluster failed
If you are using PersistentVolumeClaim you need a volume provisioner for Dynamic Volume Provisioning. The bigger cloud providers typically has this.
If you don't have a volume provisioner in your cluster, you have to create a PersistentVolume resource and possibly also a StorageClass and declare how to use your storage system.
Take a look: portainer-on-kubernetes.
So in your case as you have mentioned you can install external volume provisioner - NFS subdir external provisioner.
