Understanding Kubernetes Storage: Getting in Deep by Writing a CSI Driver
summary
Walks through building a working CSI driver for an AFS-derived storage backend using Go, the Kubernetes API and the CSI spec; driver runs as a daemonset on every node exposing identity/controller/node gRPC services and uses standard sidecars like the external-provisioner and external-attacher. Explains PVC→PV→VolumeAttachment lifecycle, implements topology-aware scheduling and wait-for-first-consumer binding, and shows the driver can veto or delay publishing (e.g., until data migration completes), proving the approach operates end-to-end.
