這篇文章主要介紹“如何使用NAS動態存儲卷創建有狀態應用”,在日常操作中,相信很多人在如何使用NAS動態存儲卷創建有狀態應用問題上存在疑惑,小編查閱了各式資料,整理出簡單好用的操作方法,希望對大家解答”如何使用NAS動態存儲卷創建有狀態應用”的疑惑有所幫助!接下來,請跟著小編一起來學習吧!
目前動態生成NAS存儲卷的實現:在一個已有文件系統上,自動生成子文件系統(子目錄),并生成目標存儲卷(PV);
生成的PV名字為:pvc-${pv-uid}
registry.cn-hangzhou.aliyuncs.com/acs/alicloud-nas-controller:v3.1.0-k8s1.11
部署前要先創建一個NAS文件系統,并添加掛載點。注意:掛載點需要和集群處于同一個VPC內部。
部署模板中,創建Storageclass的時候可以定義reclaimPolicy類型,可以為Retain或者Delete;
根據自己NAS掛載點修改NFS_SERVER、server的值;
