csi-plugin

csi-plugin mounts and unmounts volumes for ACK clusters, supporting disks, File Storage NAS (NAS), and OSS buckets.

Overview

csi-plugin follows the Container Storage Interface (CSI) specification to mount disks, NAS file systems, and OSS buckets. The latest version is installed by default in ACK clusters running Kubernetes 1.16 or later. csi-plugin manages the full volume lifecycle: create, mount, unmount, delete, and expand.

Usage notes

See Manage the csi-plugin and csi-provisioner add-ons.

Important

To use csi-plugin 1.22.8-8d3a569-aliyun or later, ensure the cluster runs Kubernetes 1.21 or later.
For cluster stability on Kubernetes 1.20 or later, update csi-plugin to 1.24.9-74f8490-aliyun or later.
The csi-plugin in ACK Edge clusters supports only NAS volumes.
When you upgrade csi-plugin, upgrade csi-provisioner to the same version.
