링크 복사링크가 클립보드에 복사되었습니다!
OpenShift Container Platform is capable of provisioning persistent volumes (PVs) using the Container Storage Interface (CSI) driver for IBM® Virtual Private Cloud (VPC) Block Storage.
Familiarity with persistent storage and configuring CSI volumes is recommended when working with a CSI Operator and driver.
To create CSI-provisioned PVs that mount to IBM Cloud® VPC Block storage assets, OpenShift Container Platform installs the IBM Cloud® VPC Block CSI Driver Operator and the IBM Cloud® VPC Block CSI driver by default in the openshift-cluster-csi-drivers namespace.
-
The IBM Cloud® VPC Block CSI Driver Operator provides three storage classes named
ibmc-vpc-block-10iops-tier(default),ibmc-vpc-block-5iops-tier, andibmc-vpc-block-customfor different tiers that you can use to create persistent volume claims (PVCs). The IBM Cloud® VPC Block CSI Driver Operator supports dynamic volume provisioning by allowing storage volumes to be created on demand, eliminating the need for cluster administrators to pre-provision storage. You can disable this default storage class if desired (see Managing the default storage class). - The IBM Cloud® VPC Block CSI driver enables you to create and mount IBM Cloud® VPC Block PVs.
