本文介紹如何在Kubernetes叢集中手動安裝CSI外掛程式,並將NAS檔案系統掛載至Kubernetes叢集進行訪問。
重要
CSI外掛程式為開源組件,阿里雲不會對該外掛程式的版本、安全性、準確性進行任何保證,在使用過程中阿里雲不對由此引發的任何損害承擔責任。請您根據實際情況進行選擇合適的方式掛載訪問NAS。如使用過程中遇到問題,您可以前往GitHub上提交issue進行交流。
前提條件
使用限制
NAS檔案系統在掛載連通性、檔案系統數量及協議類型等方面存在相應的約束條件。詳細資料,請參見使用限制。
重要
在沒有卸載NAS檔案系統前,務必不要刪除NAS掛載點,否則會造成作業系統無響應。
操作步驟
部署CSI外掛程式。
建立用於部署CSI-ALL的YAML檔案。
將以下內容儲存為csi-all.yaml,其中ACCESS_KEY_ID和ACCESS_KEY_SECRET的value請替換為自身阿里雲帳號(主帳號)的AccessKey ID和AccessKey Secret,擷取方式請參見建立AccessKey。
csi-all.yaml
