cnfs-nas-daemon: Introduction and change log-Container Service for Kubernetes(ACK)-阿里云帮助中心

To use advanced NAS or CPFS features in an ACK cluster, install the cnfs-nas-daemon component to centrally manage and deploy the required clients as containers. This simplifies operations.

Component overview

The cnfs-nas-daemon component runs as a DaemonSet, deploying one Pod on each node. Each Pod is pre-configured with the client tools required for Alibaba Cloud File Storage (NAS and CPFS), such as the EFC client for mounting NAS.

When you enable the mount proxy feature in the CSI plugin, the plugin forwards volume mount requests to the cnfs-nas-daemon Pod on the node. This proxy model decouples the client from the node environment, enabling centralized, containerized client management.

Usage notes

To install the component, see Manage the cnfs-nas-daemon component.
