How to create persistent volumes to run scale set in kubernetes mode?

[OmpahDev]

I'm going through the process of deploying runner scale sets and I noticed this paragraph in the documentation (link)

Kubernetes mode relies on persistent volumes to share job details between the runner pod and the container job pod. For more information, see the [Persistent Volumes](https://kubernetes.io/docs/concepts/storage/persistent-volumes/) section in the Kubernetes documentation.

To use Kubernetes mode, you must do the following.

Create persistent volumes available for the runner pods to claim.
Use a solution to automatically provision persistent volumes on demand.
For testing, you can use a solution like [OpenEBS](https://github.com/openebs/openebs).

I'm a bit lost on what this actually is or how to do this. It talks about OpenEBS for testing and then the values file includes a brief description of this here but how is this actually done in real-world (ie. not testing) use? This seems like a pretty big thing to just gloss over...

Can the documentation be updated with an example/tutorial of how to actually do this? (If such a thing already exists, I couldn't find it).
