Use and manage NAS file systems by using Container Network File System (CNFS) - Container Service for Kubernetes

Container Network File System (CNFS) abstracts Alibaba Cloud file storage into a Kubernetes object (CRD) for independent management. This includes operations such as creating, deleting, mounting, monitoring, and scaling out file systems. You can use CNFS to manage NAS file systems independently to improve their performance and Quality of Service (QoS).This topic describes how to use CNFS to manage NAS file systems and apply them to workloads.

Prerequisites

File Storage NAS is activated.
When you log on to the File Storage NAS product page for the first time, activate the service as prompted.
An ACK Pro managed cluster is created. The cluster version must be 1.20 or later. If you use kubectl to manage CNFS, cluster version 1.20 is supported. For more information, see Create an ACK managed cluster.
The versions of the storage-related components csi-plugin, csi-provisioner, and storage-operator meet the following requirements:
- The csi-plugin and csi-provisioner components are version v1.20.5-ff6490f-aliyun or later.
- The storage-operator component is version v1.18.8.56-2aa33ba-aliyun or later. If you use the console to manage CNFS, the version must be v1.26.2-1de13b6-aliyun or later.
Capacity NAS and Performance NAS file systems are supported. Advanced and Extreme NAS file systems are not supported. If you want to use KMS to encrypt a NAS file system, you must first activate the KMS service. For more information, see Activate Key Management Service.

Function introduction

You can use one of the following methods to manage NAS file systems with CNFS:

Method 1: Use CNFS to create a default NAS file system
Create a default NAS file system using CNFS and dynamically mount it to a workload using a volume.
Method 2: Use CNFS to create a custom NAS file system
Create a custom NAS file system using CNFS and mount it to a workload using a static or dynamic volume.
Method 3: Use CNFS to configure an existing NAS file system
Configure an existing NAS file system using CNFS and mount it to a workload using a static or dynamic volume.

Method 1: Use CNFS to create a default NAS file system

Important

A Capacity NAS or Performance NAS file system is created based on the VPC where the current cluster is located. Extreme NAS file systems are not supported. If the current region does not support Capacity NAS file systems, a Performance NAS file system is created. By default, files are not encrypted.

kubectl

Use the following YAML file to create a default CNFS file system. The file system is automatically mounted to a NAS file system and attached to a Deployment and a StatefulSet.
