Unable to create multiple replicas on kubernetes cluster

[gaddehyd]

Hi,

I was trying to deploy Oracle single instance database on kubernetes cluster with 2 replicas but is failing with unknown reason. After 7% copying database files failing and trying to copy again. With single replica instance is working fine. Is there any restriction for multiple replicas on Oracle express database?

Yes, I think the K8s extension is not packaged with the express database image. Are you using the image from Oracle Container Registry?

Btw, Oracle Database Operator is available for K8s deployments

Yes I am using Oracle container registory repo image.
I am not sure weather my image is packed with extension or not. Let me review it.

Also XE supports only one database ?
