From PVC to Mount Point: Dissecting a...
summary
Walks through an actual custom CSI driver implementation, showing the Digital Ocean test plugin that calls the storage API, the createVolume RPC implementation, and how the CSI provisioner and attacher sidecars create the PV and VolumeAttachment resources. Shows controller PublishVolume attaching the block device, the node plugin mounting to a staging and target path, and kubelet exposing it to the pod. Demonstrates the driver successfully provisioning, attaching, and mounting volumes so teams can debug each failing step.
