如何通过CSI插件挂载NAS文件系统 - 文件存储 NAS

本文介绍如何在Kubernetes集群中手动安装CSI插件，并将NAS文件系统挂载至Kubernetes集群进行访问。

重要

CSI插件为开源组件，阿里云不会对该插件的版本、安全性、准确性进行任何保证，在使用过程中阿里云不对由此引发的任何损害承担责任。请您根据实际情况进行选择合适的方式挂载访问NAS。如使用过程中遇到问题，您可以前往GitHub上提交issue进行交流。

前提条件

已创建NFS协议文件系统。具体操作，请参见创建文件系统。
若需要加密NAS文件系统中的数据，请在创建NAS文件系统时配置加密类型。
已添加挂载点。具体操作，请参见管理挂载点。
已自建Kubernetes集群且集群版本为1.16及以上版本。
已确认Pod调度节点的安全组规则开放111端口和2049端口。具体操作，请参见添加安全组规则。
如果您的Kubernetes集群部署在线下IDC，请确保已打通IDC与阿里云的网络。您可通过阿里云高速通道、智能接入网关或者VPN网关打通IDC和云上网络。相关参考如下：

使用限制

NAS文件系统在挂载连通性、文件系统数量及协议类型等方面存在相应的约束条件。详细信息，请参见使用限制。

重要

在没有卸载NAS文件系统前，务必不要删除NAS挂载点，否则会造成操作系统无响应。

操作步骤

部署CSI插件。

创建用于部署CSI-ALL的YAML文件。

将以下内容保存为csi-all.yaml，其中ACCESS_KEY_ID和ACCESS_KEY_SECRET的value请替换为自身阿里云账号（主账号）的AccessKey ID和AccessKey Secret，获取方式请参见创建AccessKey。

csi-all.yaml
