Description

Currently only hostPath, emptyDir, and PVC volume types are accepted for Kubernetes-deployed drivers and executors.

flexVolume types allow for pluggable volume drivers to be used in Kubernetes - a widely used example of this is the Rook deployment of CephFS, which provides a POSIX-compliant distributed filesystem integrated into K8s.
