Configure a PVC

Contributors kcantrel

This sections includes instructions on how to create a PersistentVolumeClaim (PVC) that uses the configured Kubernetes StorageClass to request a PV.
If successful, you can then mount the PV to a pod.

Create the PVC

A PersistentVolumeClaim (PVC) is a request for access to the PersistentVolume on the cluster. The PVC can be configured to request storage of a certain size or access mode. Using the associated StorageClass, the cluster administrator can control more than PersistentVolume size and access mode—​such as performance or service level.

After you create the Trident backend and StorageClass you can create a PVC. After the PVC is created, you can mount the volume in a pod.

Sample manifests

The following examples show basic PVC configuration options.

PVC with RWX access

This example shows a basic PVC with RWX access that is associated with a StorageClass named basic-csi.

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: pvc-storage
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1Gi
  storageClassName: ontap-gold
PVC using iSCSI example

This example shows a basic PVC for iSCSI with RWO access that is associated with a StorageClass named protection-gold.

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: pvc-san
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  storageClassName: protection-gold

Create PVC

Steps

  1. Create the PVC.

    kubectl create -f pvc.yaml

  2. Verify the PVC status.

    kubectl get pvc
NAME        STATUS VOLUME     CAPACITY ACCESS MODES STORAGECLASS AGE
pvc-storage Bound  pv-name 2Gi      RWO                       5m

Refer to Kubernetes and Trident objects for details on how storage classes interact with the PersistentVolumeClaim and parameters for controlling how Trident provisions volumes.
