Kubernetes provisioner

To enable dynamic provisioning, a cluster administrator needs to pre-create one or more StorageClass objects for users.

kubectl get storageclass
NAME            PROVISIONER             RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
gp2 (default)   kubernetes.io/aws-ebs   Delete          WaitForFirstConsumer   false                  11d

• kubectl get provisioner
• kubectl describe provisioner
• kubectl patch provisioner
• kind: provisioner

Provisioners:

kubernetes.io/aws-ebs
k8s.io/minikube-hostpath
kubernetes.io/gce-pd
