Add a sprinkling of High Availability?

Would be great if one could scale up with multiple replicas in a RAC One Node configuration. Draining the kubernetes node for any maintenance while having only a single replica deployed would cause an outage.

The Oracle repo has an Issue logged for developing a Oracle RAC Helm chart. First step would be to develop the raw yaml, as you've done.

Hi Gregory, I can relocate a database using cordon / uncordon, have you tried that ?

The Pure CSI Driver supports raw block so could try RAC, but as yet not given it a go.

Cheers

Shutting down the pod and starting it elsewhere takes time and interrupts client connections.

Solving the RAC networking requirements on Kubernetes may be more challenging than the storage piece. Picked it up here:
