Hello Hemant,
I was able to define my storageclass to change default to type ‘encrytped’ but
anytime I tried to add the reclaim policy as default ‘retain’ at the storage
class level it failed to work properly.
My current sc file
apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
annotations:
storageclass.beta.kubernetes.io/is-default-class: "true"
creationTimestamp: 2017-11-20T15:17:33Z
name: gp2-encrypted
resourceVersion: "444871"
selfLink: /apis/storage.k8s.io/v1/storageclasses/gp2-encrypted
uid: ef0a4237-ce05-11e7-890f-0e8b400c9cda
parameters:
encrypted: "true"
kmsKeyId: xxxxxxxxxxxxxxxxxxxxxx
type: gp2
ideally I’d like the pv to be dynamically created with the retain policy by
default. It’s not convenient to have our developers request a pv, (get ebs vol
id first) then create pv.yml with that set to retain. And the logging and
metrics dynamically creates the pv during install so they are ‘delete’ reclaim
policy too. I have to manually delete the pvc, recreate with policy retain’ to
have those stay.
Is there a current work around, that is not manual, to dynamically provision pv
with retain reclaimpolicy?
Thanks,
Todd

Subject: Re: AWS EBS and PV Reclaim Policy Question
I suppose you are currently using dynamic provisioning and want to configure
reclaim policy via storageClass for all dyanmically created PVs?
We just had this feature merged in Openshift-3.8 branch where you can configure
reclaim policy of all dynamically created PVs. This feature however isn't
available in 3.6. We haven't considered backporting the feature back to 3.6
because it involves API change.

We have aws and openshift origin cluster working well and using EBS for storage

not figured out how to set that in my playbooks?
Does anyone know how to change the default persistentVolumeReclaimPolicy from
‘delete’ to ‘retain’?
My other option I could use is create the EBS volume manually and then create
the pv-manual.yml file to point to that Vol ID and set the
persistentVolumeReclaimPolicy. But this is not ideal.
I’d also like to set this pv reclaim policy to ‘retain’ for our logging and
metrics persistent storage but have not found setting for this in playbooks.
We’re on v.3.6.
Thank you,
Todd Walters
