3.2. Persistent storage using Azure

Procedure

1. In the OpenShift Container Platform console, click Storage Storage Classes.
2. In the storage class overview, click Create Storage Class.

3. Define the desired options on the page that appears.

   1. Enter a name to reference the storage class.
   2. Enter an optional description.
   3. Select the reclaim policy.

   4. Select kubernetes.io/azure-disk from the drop down list.

      1. Enter the storage account type. This corresponds to your Azure storage account SKU tier. Valid options are Premium_LRS, Standard_LRS, StandardSSD_LRS, and UltraSSD_LRS.

      2. Enter the kind of account. Valid options are shared, dedicated, and managed.

         重要

         Red Hat only supports the use of kind: Managed in the storage class.

         With Shared and Dedicated, Azure creates unmanaged disks, while OpenShift Container Platform creates a managed disk for machine OS (root) disks. But because Azure Disk does not allow the use of both managed and unmanaged disks on a node, unmanaged disks created with Shared or Dedicated cannot be attached to OpenShift Container Platform nodes.

   5. Enter additional parameters for the storage class as desired.
4. Click Create to create the storage class.

Procedure

1. In the OpenShift Container Platform console, click Storage Persistent Volume Claims.
