A school district workload uses only emptyDir volumes and no PersistentVolumeClaims. Must the cluster install a CSI driver for those Pods to run?
Select an answer to reveal the explanation.
Short Explanation
emptyDir is like a scratch pad the node creates for the Pod’s lifetime—no external SAN ticket required. CSI shines when you want dynamic disks for PVCs. Scratch-only workloads can run without a CSI driver.
Full Explanation
emptyDir volumes are provided by kubelet as ephemeral node-local storage tied to the Pod lifecycle. Dynamic provisioning of external persistent volumes uses StorageClasses and CSI drivers. Clusters that never consume PVCs backed by external storage do not require CSI solely for emptyDir.
