Bound Pvc To Pv

Specifying claimRef a PV not prevent specified PVC being bound to different PV. PVC free choose PV to bind according the normal binding process. Therefore, avoid scenarios ensure claim bound to volume want, must ensure both volumeName claimRef specified.

$ kubectl apply -f pv-manifest.yaml $ kubectl apply -f pvc-manifest.yaml. above command create PV a PVC the cluster. Further, can verify the binding correct. can achieve by presenting PVC information kubectl get. Thus, result show the PVC in Bound state in example below:

Once bound, PersistentVolumeClaim binds exclusive, of they bound. PVC to PV binding a one-to-one mapping, a ClaimRef is bi-directional binding the PersistentVolume the PersistentVolumeClaim.

The PVC PV binding appears a 1:1 mapping at times users to attach existing PV to new PVC could in namespace. Lets start: you know, bound PVC a `reclaimPolicy` is default "delete". the PV you to attach a PVC of "delete" policy need edit PV .

static: PV an object, PVC finds uses specific PV; dynamic: PVC attempts dynamically create volume runtime; way, PVC Bound to PV. the case dynamic provisioning, relationship always the PV-PVC pair. we a resolved PVC, pods get assigned use it. 2.3. Reclaim Policy

In case, administrator specify PVC the PV the claimRef field. PV only able bind a PVC has same and namespace in claimRef. PVC's access modes resource requests still satisfied order the PV PVC to bound, the label selector ignored.

Binding: PV bound to PVC (Persistent Volume Claim) a pod declares storage requirement matches PV's specifications. step ensures the PV meets requirements a specific pod. Usage the pod: the binding process complete, PV be by pod. pod read write the mounted volume .

Binding PVC to PV: Kubernetes control plane attempts bind PVC to available PV matches PVC's requirements. binding process ensures the PVC satisfied a .

Once PVC bound a PV, PV's lifespan be attached the PVC. binding exclusive, as long the PVC exists, PV not reused. Dynamic Provisioning.
