Can a PVC be bound to a specific PV?

by

There is a way to pre-bind PVs to PVCs today, here is an example showing how:

  1. Create a PV object with a ClaimRef field referencing a PVC that you will subsequently create: 
     $ kubectl create -f pv.yaml
 persistentvolume "pv0003" created

    where pv.yaml contains:

     apiVersion: v1
 kind: PersistentVolume
 metadata:
   name: pv0003
 spec:
   storageClassName: ""
   capacity:
     storage: 5Gi
   accessModes:
     - ReadWriteOnce
   persistentVolumeReclaimPolicy: Retain
   claimRef:
     namespace: default
     name: myclaim
   nfs:
     path: /tmp
     server: 172.17.0.2
  2. Then create the PVC with the same name: 
     kind: PersistentVolumeClaim
 apiVersion: v1
 metadata:
   name: myclaim
 spec:
   storageClassName: ""
   accessModes:
     - ReadWriteOnce
   resources:
     requests:
       storage: 5Gi
  3. The PV and PVC should be bound immediately: 
     $ kubectl get pvc
 NAME      STATUS    VOLUME    CAPACITY   ACCESSMODES   AGE
 myclaim   Bound     pv0003    5Gi        RWO           4s
 $ ./cluster/kubectl.sh get pv
 NAME      CAPACITY   ACCESSMODES   STATUS    CLAIM             REASON    AGE
 pv0003    5Gi        RWO           Bound     default/myclaim             57s
