spec.storageClass: cold-storage -> spec.storageClassName: standard (to map to the StorageClass in the rest of the docs)
Also needs the addition of spec.accessModes: - ReadWriteMany (for example)
Job & CronJob
K8s also dislikes spec.template.spec.containers.version in both the Job and CronJob, resolved through tagging the version onto the end of the image instead (spec.template.spec.containers.image: couchbase/server:enterprise-5.5.1)
Additionally both also need the spec.template.spec.restartPolicy field (either Always, Never or OnFailure).
