The CSI external-resizer is a sidecar container that watches the Kubernetes API server for PersistentVolumeClaim object edits and triggers ControllerExpandVolume operations against a CSI endpoint if user requested more storage on PersistentVolumeClaim object.


CSI drivers that support Kubernetes volume expansion should use this sidecar container, and advertise the CSI VolumeExpansion plugin capability.


The CSI external-resizer is deployed as a controller. See deployment section for more details.
