红帽全球峰会6.18. OpenStack Cinder CSI Driver Operator
6.18.1. Overview
OpenShift Container Platform is capable of provisioning persistent volumes (PVs) using the Container Storage Interface (CSI) driver for OpenStack Cinder.
Familiarity with persistent storage and configuring CSI volumes is recommended when working with a Container Storage Interface (CSI) Operator and driver.
To create CSI-provisioned PVs that mount to OpenStack Cinder storage assets, OpenShift Container Platform installs the OpenStack Cinder CSI Driver Operator and the OpenStack Cinder CSI driver in the openshift-cluster-csi-drivers namespace.
- The OpenStack Cinder CSI Driver Operator provides a CSI storage class that you can use to create PVCs. You can disable this default storage class if desired (see Managing the default storage class).
- The OpenStack Cinder CSI driver enables you to create and mount OpenStack Cinder PVs.
OpenShift Container Platform provides automatic migration for the Cinder in-tree volume plugin to its equivalent CSI driver. For more information, see CSI automatic migration.
