csi-provisioner automates volume provisioning for Container Service for Kubernetes (ACK) clusters, with support for cloud disks, File Storage NAS (NAS), and Object Storage Service (OSS) file systems.
Overview
csi-provisioner handles the lifecycle of persistent volumes in ACK, working alongside csi-plugin to deliver storage operations. Together, they support the following capabilities:
| Capability | Description |
|---|---|
| Dynamic provisioning | Automatically creates and deletes cloud disk, NAS, and OSS volumes through StorageClass configurations. |
| Static provisioning | Use existing cloud disks, NAS file systems, or OSS buckets as persistent volumes. |
| Volume expansion | Expands persistent volume claims (PVCs) online without downtime. |
| Volume snapshots | Creates and restores snapshots for cloud disk volumes. |
| Storage topology awareness | Schedules volumes in the availability zone of the target node to avoid cross-zone mount failures. |
| Node disk limit enforcement | Automatically determines and enforces the maximum number of cloud disks that can be mounted to a node based on instance type. |
| Metrics and observability | Exposes storage metrics for cloud disk, NAS, and OSS volumes, including I/O monitoring and capacity reporting. |
Important
In ACK Edge clusters, csi-provisioner supports only NAS volumes.
Limitations
The following table summarizes the Kubernetes version requirements for key csi-provisioner releases. Backport versions cover Kubernetes 1.20–1.24 for clusters that cannot be upgraded.
| csi-provisioner version | Kubernetes version required |
|---|---|
| v1.33.1 and later | 1.26 or later |
| v1.22.8-8d3a569-aliyun and later | Later than 1.20 |
| All versions | 1.14 or later |
Important
When you upgrade csi-provisioner, upgrade csi-plugin to the same version at the same time. Starting from v1.18.8.47-906bd535-aliyun, csi-provisioner and csi-plugin share the same image address.
Usage notes
For instructions on installing, upgrading, and managing csi-provisioner, see Manage the csi-plugin and csi-provisioner components.
