I am using rookio on Kubernetes with CoreOS for dynamically creating Persistent Volume.
So I create a PersistentVolumeClaim (kubectl create -f postgres-pvc.yaml) and apply a patch for persistentVolumeReclaimPolicy to Retain. I do a "kubectl get pv"and I can see a dynamically created persistentvolume and is bound. Now when I delete the PersitentVolumeClaim the status goes to Released.
I have stored some precious data in that persistentvolume. Is there a way I can reuse that persistentvolume that has gone into Released status?

If you have precious data that you want to use in another PostgreSQL pod, maybe StatefulSets is which you are looking for, as it allows:
Stable, persistent storage [...] across Pod (re)schedulings.
Therefore, I would advise you to deploy your PostgreSQL database as a StatefulSet. You would need to check that your already existing Volume is bound.
