CCE CSI CDS Plugin Description

Updated at：2025-10-27

Component introduction

The CCE CSI CDS Plugin enables Baidu AI Cloud CDS storage to be mounted in Pods using PV/PVC and supports the dynamic creation of PVs.

Component function

Containers, being inherently non-persistent, lose their data when deleted. Persistent volumes (volumes) resolve issues of data sharing and storage persistence for containers. Kubernetes provides PV (PersistentVolume) and PVC (PersistentVolumeClaim) API resources to abstract storage management details.

Using Baidu AI Cloud’s CDS service, users can create PV and PVC resources in the cluster to directly mount CDS as persistent volumes into containers, simplifying the implementation of persistent storage solutions for container clusters.

Install component

  1. Sign in to the Baidu AI Cloud official website and enter the management console.
  2. Select Product Tour - Containers - Baidu Container Engine and click to enter the CCE management console.
  3. Click Cluster Management - Cluster List in the left navigation pane.
  4. Click on the target cluster name in the Cluster List page to navigate to the cluster management page.
  5. On the Cluster Management page, click O&M & Management > Component Management.
  6. In the component management list, select the CCE CSI CDS Plugin component and click Install, then complete the relevant configurations in the pop-up box.
ConfigMap Required/Optional Configuration
KubeletRootPath Required Configure the kubelet data directory on the node to enable the component to register with the node’s kubelet. It is essential to input the correct kubelet data directory, and multiple entries can be specified for matching.
maxVolumesPerNode Required Set the maximum number of CDS PVs that can be mounted on each node within the cluster.
  1. Click the OK button to complete the component installation.

Deployment status

After installing the CCE CSI CDS Plugin component, the following objects will be deployed in the Kubernetes cluster:
