How can predefined PV and PVC assigned to

MongoDB Percona Operator for MongoDB
1

Hello

Currently at the cluster creation the PVs and PVCs are created. Is it possible to create the PVs and PVCs beforehand and assign them to the rs’s and cfg’s ?

This can be done if you create PVCs by adhering the naming rules. For example if you have a cluster named cluster1, you can create PVCs to be used by rs0 pods like:

pvc/mongod-data-cluster1-rs0-0
pvc/mongod-data-cluster1-rs0-1
pvc/mongod-data-cluster1-rs0-2

But I’m curious, what do you want to achieve by creating PVCs yourself?

Thanks - let me try that !

Well … sometimes ppl do funny stuff - like deleting the wrong GKE cluster. And in that case the PV and PVC and the disks are getting deleted.

If I can create them myself, I can make sure that the disks get not deleted and afterwards I can reassign them.
