The wiki page on [Running-FoundationDB-in-the-Cloud](https://github.com/apple/foundationdb/wiki/Running-FoundationDB-in-the-Cloud#choosing-the-right-disks) recommends ephemeral disks.

> For most deployments, this is probably what you want.

However, I could not find an option to use ephemeral disks in the Kubernetes operator. Is this supported somehow?

The operator already supports that by defining a `StorageClass` in your cluster that is backed by a Local Persistent Volume ([Kubernetes 1.14: Local Persistent Volumes GA | Kubernetes](https://kubernetes.io/blog/2019/04/04/kubernetes-1.14-local-persistent-volumes-ga)). In the process settings you can define a `VolumeClaimTemplate`, that template can point to a specific `StorageClass` (otherwise a default one will be used) that will make use of the LPV. If you want to use LPVs for all processes you can use the “general” process key otherwise use a more specific one. Stateless processes won’t create a PVC so you don’t have to worry about them.

I hope that helped.
