Ephemeral Volume](https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/596-csi-inline-volumes) feature allows CSI volumes to be specified directly in the pod specification for ephemeral use cases. They can be used to inject arbitrary states, such as configuration, secrets, identity, variables or similar information, directly inside pods using a mounted volume. This was initially introduced in 1.15 as an alpha feature, and it moved to GA. This feature is used by some CSI drivers such...
