- When upgrading from a deployment with an existing DB, provide the DB
details in the cluster CR, to perform data import.
- Upgrade flow is as follows:
- If DB sts exist:
- Stop core\endpoints pods
- Create a cnpg cluster with import details in the CR
- The cnpg operator will start the first instance and deploy an
import job to import the data. After the import is completed, the
second instance will started.
- Wait for cluster to complete import and become Ready
- Once ready scale down the noobaa-db-pg sts to 0 replicas.
- The reconciliation will wait for the cluster to be ready, and a
temp error is returned until it is.
- The old sts is not deleted, to have it around for backup. In future
versions we should cleanup all the leftovers.
