Use ephemeral storage for testing Splunk Enterprise

Use ephemeral storage for non-production Splunk Enterprise testing.

For testing and demonstration of Splunk Enterprise instances, you can use ephemeral storage instead of persistent storage. Use the ephemeralStorage field under the etcVolumeStorageConfig and varVolumeStorageConfig spec to mount local, ephemeral volumes for /opt/splunk/etc and /opt/splunk/var using the Kubernetes emptyDir feature.

For example:

apiVersion: enterprise.splunk.com/v4
kind: Standalone
metadata:
  name: example
  finalizers:
  - enterprise.splunk.com/delete-pvc
spec:
  etcVolumeStorageConfig:
    ephemeralStorage: true
  varVolumeStorageConfig:
    ephemeralStorage: true
