AWS Elastic Block Store CSI Driver Operator
Overview
Red Hat OpenShift Service on AWS is capable of provisioning persistent volumes (PVs) using the AWS EBS CSI driver.
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 AWS EBS storage assets, Red Hat OpenShift Service on AWS installs the AWS EBS CSI Driver Operator (a Red Hat operator) and the AWS EBS CSI driver by default in the openshift-cluster-csi-drivers namespace.
-
The AWS EBS CSI Driver Operator provides a StorageClass by default that you can use to create PVCs. You can disable this default storage class if desired (see Managing the default storage class). You also have the option to create the AWS EBS StorageClass as described in Persistent storage using Amazon Elastic Block Store.
-
The AWS EBS CSI driver enables you to create and mount AWS EBS PVs.
About CSI
Storage vendors have traditionally provided storage drivers as part of Kubernetes. With the implementation of the Container Storage Interface (CSI), third-party providers can instead deliver storage plugins using a standard interface without ever having to change the core Kubernetes code.
CSI Operators give Red Hat OpenShift Service on AWS users storage options, such as volume snapshots, that are not possible with in-tree volume plugins.
|
Red Hat OpenShift Service on AWS defaults to using the CSI plugin to provision Amazon Elastic Block Store (Amazon EBS) storage. |
For information about dynamically provisioning AWS EBS persistent volumes in Red Hat OpenShift Service on AWS, see Persistent storage using Amazon Elastic Block Store.
