迁移Flexvolume至CSI
通过csi-compatible-controller组件迁移Flexvolume至CSI
csi-compatible-controller组件支持在Flexvolume类型的集群中安装和使用CSI组件，让Flexvolume组件和CSI组件共存于一个集群内，通过安装该组件并依次切换Flexvolume集群中应用挂载的存储类型，使Flexvolume类型的存储逐渐过渡到CSI存储。本文介绍如何通过csi-compatible-controller组件完成Flexvolume至CSI的迁移。

环境准备
安装csi-compatible-controller组件
登录容器服务管理控制台，在左侧导航栏选择集群。
在集群列表页面，单击目标集群名称，然后在左侧导航栏，选择运维管理 > 组件管理。
在组件管理页面，单击存储页签，找到csi-compatible-controller组件，单击卡片右下角的安装，然后单击确定。
安装CSI组件
csi-compatible-controller组件安装完成后，您需要使用如下YAML文件安装部署CSI组件。由于配置不同，不能通过集群的组件管理页面进行CSI组件的安装。安装时，请根据集群版本选择如下组件对应的YAML文件进行安装。请使用kubectl apply命令将YAML文件安装至集群中。
说明
替换YAML文件中镜像的地域ID，例如将
cn-hangzhou替换为您集群所在地域。将以下YAML文件中的
{{.ClusterID}}替换为您的集群ID。
集群版本为ACK 1.20及以上

上述组件部署完成后，即可在集群中同时使用Flexvolume组件和CSI组件。后续逐渐将Flexvolume类型的应用转化为CSI类型的应用。
切换应用挂载的存储类型
您需要将应用挂载使用的Flexvolume类型的存储全部转换为CSI类型，待Flexvolume集群中无Flexvolume类型的存储时，即可删除Flexvolume组件。
步骤一：转换PVC和PV为CSI类型
获取集群中所有Flexvolume类型的PVC和PV，并且将其转换为CSI类型。您可以使用命令行工具实现集群中Flexvolume类型PVC和PV的批量转换。具体操作，请参见使用Flexvolume2CSI命令行工具批量转换YAML。
本文以云盘为例，展示如何将获取到的Flexvolume类型的PVC和PV转换为CSI类型的PVC和PV。您可以根据实际情况，参考如下CSI模板进行修改。

为确保存储资源使用的存储卷不会丢失，您需要检查待迁移的Flexvolume类型的PVC和PV。如果pv.Spec.persistentVolumeReclaimPolicy为Delete，需要将其改为Retain。
apiVersion: v1
kind: PersistentVolume
metadata:
name: d-bp1bnp9homa0tyv6****

options:
VolumeId: d-bp1bnp9homa0tyv6****
persistentVolumeReclaimPolicy: **Retain**
storageClassName: alicloud-disk-available
volumeMode: Filesystem步骤三：切换单个应用挂载的存储类型
您可以参考以下步骤，将单个应用挂载的存储类型由Flexvolume切换为CSI类型。
执行以下命令，将StatefulSet的副本缩为0。
kubectl scale --replicas=0 sts/sts-test执行以下命令，删除集群中Flexvolume类型的PVC和PV。
kubectl delete pvc pvc-disk kubectl delete pv d-bp1bnp9homa0tyv6****执行以下命令，创建CSI类型的PVC和PV。
kuectl apply -f csi-pvc-pv.yaml执行以下命令，将StatefulSet重新扩容。
kubectl scale --replicas=3 sts/sts-test说明pvcClaimName和Deployment可按照同样方式进行切换。
您可以参考切换单个应用的方法依次切换所有应用挂载的存储类型。待所有应用切换完成后，即可删除Flexvolume组件。具体操作，请参见将无存储集群的Flexvolume迁移至CSI。
管理组件
升级组件
如果您已经按照上述步骤在Flexvolume集群中安装了CSI组件，但需要将CSI升级到最新版本。您可以从上文获取更新后的YAML文件，并使用kubectl apply命令将其更新到集群中。
如果您需要通过容器服务管理控制台的组件管理页面升级，则需要迁移所有的Flexvolume版本的PV、PVC到CSI后才可以执行。在Flexvolume和CSI组件共存期间，将无法通过组件管理页面进行组件升级。迁移相关操作，请参见将无存储集群的Flexvolume迁移至CSI。
删除组件
当集群中所有存储由Flexvolume迁移至CSI之后，且满足以下条件时，您可以将csi-compatible-controller组件删除。
集群中的Flexvolume组件已全部删除。
所有Flexvolume类型的PV都已删除。
检查确认Kubelet的
--enable-controller-attach-detach参数都已变为true。如不满足，请修改。具体操作，请参见将无存储集群的Fllexvolume迁移至CSI文档的步骤三和步骤四。
