About csi-resizer

csi-resizer is a Kubernetes Container Storage Interface (CSI) sidecar component that handles online volume expansion. It watches for PersistentVolumeClaim (PVC) resize requests and coordinates volume expansion with CSI drivers through gRPC calls.

The component monitors the Kubernetes API for PVC resize requests, calls the CSI driver's ControllerExpandVolume method, and updates the PVC and PV objects with the new size. It supports leader election for high availability and handles various storage class resize policies.
