Introduction and release notes for the cnfs-nas-daemon add-on-Container Service for Kubernetes(ACK)-阿里云帮助中心

The cnfs-nas-daemon add-on centralizes the containerized deployment and management of storage clients required for advanced features of File Storage NAS (NAS) and Cloud Parallel File Storage (CPFS) in Container Service for Kubernetes (ACK) clusters, simplifying operations and maintenance.

Overview

The cnfs-nas-daemon add-on runs as a DaemonSet with one pod per node. Each pod is preloaded with the storage clients required for Alibaba Cloud file storage services (NAS and CPFS), such as the EFC client for mounting NAS file systems.

When mount proxy is enabled in csi-plugin, csi-plugin forwards volume mount requests to the cnfs-nas-daemon pod on the local node. This approach decouples storage clients from the host environment and provides centralized, containerized client management.

Usage notes

To install the add-on, see Manage the cnfs-nas-daemon add-on.
