6.9.1. 概述

OpenShift Container Platform 可以使用 AWS EBS CSI 驱动程序置备持久性卷 (PV)。
在使用 Container Storage Interface (CSI) Operator 和驱动时，我们建议用户需要熟悉持久性存储和配置 CSI 卷。
要创建挂载到 AWS EBS 存储资产中的 CSI 置备 PV，OpenShift Container Platform 在 openshift-cluster-csi-drivers 命名空间中默认安装 AWS EBS CSI Driver Operator (Red Hat operator)和 AWS EBS CSI 驱动程序。
- AWS EBS CSI Driver Operator 默认提供了一个 StorageClass，您可使用它来创建 PVC。如果需要，您可以禁用此默认存储类 (请参阅管理默认存储类)。您还可以选择创建 AWS EBS StorageClass，如使用 Amazon Elastic Block Store 的持久性存储所述。
- AWS EBS CSI 驱动程序允许您创建并挂载 AWS EBS PV。
注意
如果您在 OpenShift Container Platform 4.5 集群上安装了 AWS EBS CSI Operator 和驱动程序，必须在升级到 OpenShift Container Platform 4.21 前卸载 4.5 Operator 和驱动程序。
