Disks can be automatically created by using alicloud-disk-controller. This topic describes the release notes for the alicloud-disk-controller component.

Introduction

To create dynamically provisioned persistent volumes (PVs) in a Kubernetes cluster that uses FlexVolume, you must install alicloud-disk-controller. This is because FlexVolume cannot be used to create dynamically provisioned PVs.

Usage notes

For more information about how to install alicloud-disk-controller, see Install and upgrade FlexVolume.
