Persistent Volume Claim

In this section, we will take a look at Persistent Volume Claim

Now we will create a Persistent Volume Claim to make the storage available to the node.

Volumes and Persistent Volume Claim are two separate objects in the Kubernetes namespace.

Once the Persistent Volume Claim created, Kubernetes binds the Persistent Volumes to claim based on the request and properties set on the volume.

Persistent Volume

File Name : pv-definition.yaml

kind: PersistentVolume
apiVersion: v1
metadata:
    name: pv-vol1
spec:
    accessModes: [ "ReadWriteOnce" ]
    capacity:
     storage: 1Gi
    hostPath:
     path: /tmp/data

kubectl create -f pv-definition.yaml

kubectl get pv

If properties not matches or Persistent Volume is not available for the Persistent Volume Claim then it will display the pending state.

Persistent Volume Claim

File Name : pvc-definition.yaml

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: myclaim
spec:
  accessModes: [ "ReadWriteOnce" ]
  resources:
   requests:
     storage: 1Gi

kubectl create -f pvc-definition.yaml

kubectl get pvc

Delete Persistent Volume Claim

kubectl delete pvc myclaim

Delete Persistent Volume

kubectl delete pv pv-vol1
