CCE CSI PFS L2 Plugin

Updated at：2025-10-27

Component introduction

The CCE CSI PFS L2 Plugin facilitates mounting Baidu AI Cloud L2-type PFS storage in Pods via 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 PFS L2 service, users can create PV and PVC resources in the cluster to mount PFS L2 as persistent volumes directly into containers. This simplifies the process of providing persistent storage solutions for container clusters without focusing on underlying implementation intricacies.

Prerequisites

  • A PFS mount service has been created. For more details, please refer to PFS Mount Service

Usage restrictions

  • For the list of OS and kernel versions supported by PFS L2, please refer to Usage Restrictions (Extreme L2 PFS)

Install component

  1. Sign in to the Baidu AI Cloud official website and enter the management console.
  2. Select Product Tour > Container > Baidu Container Engine and click to enter the CCE management console.
  3. Click Cluster Management > Cluster List in the left navigation bar.
  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 PFS L2 Plugin component and click Install, then complete the relevant configurations in the pop-up box.
ConfigMap Required/Optional Configuration
Associated mount service Required Specify the PFS mount service associated with the component. The mount service must be within the same VPC as the cluster. Once mounted, the cluster gains access to the PFS instance bound to the mount service.
  1. Click the OK button to complete the component installation.

Deployment status

After installing the CCE CSI PFS L2 Plugin component, the following objects will be deployed in the Kubernetes cluster:
