= Creating the Azure storage class
|
|
|
|
Storage classes are used to differentiate and delineate storage levels and
|
|
usages. By defining a storage class, users can obtain dynamically provisioned
|
|
persistent volumes.
|
|
|
|
.Procedure
|
|
|
|
. In the {product-title} web console, click *Storage* -> *Storage Classes*.
|
|
|
|
. In the storage class overview, click *Create Storage Class*.
|
|
|
|
. Define the desired options on the page that appears.
|
|
|
|
.. Enter a name to reference the storage class.
|
|
|
|
.. Enter an optional description.
|
|
|
|
.. Select the reclaim policy.
|
|
|
|
.. Select `kubernetes.io/azure-disk` from the drop down list.
|
|
|
|
... Enter the storage account type. This corresponds to your Azure
|
|
storage account SKU tier. Valid options are `Premium_LRS`, `PremiumV2_LRS`, `Standard_LRS`,
|
|
`StandardSSD_LRS`, and `UltraSSD_LRS`.
|
|
+
|
|
[IMPORTANT]
|
|
====
|
|
The skuname `PremiumV2_LRS` is not supported in all regions, and in some supported regions, not all of the availability zones are supported. For more information, see link:https://learn.microsoft.com/en-us/azure/virtual-machines/disks-deploy-premium-v2[Azure doc].
|
|
====
|
|
|
|
... Enter the kind of account. Valid options are `shared`, `dedicated,`
|
|
and `managed`.
|
|
+
|
|
[IMPORTANT]
|
|
====
|
|
Red Hat only supports the use of `kind: Managed` in the storage class.
|
|
|
|
With `Shared` and `Dedicated`, Azure creates unmanaged disks, while {product-title} 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 {product-title} nodes.
|
|
====
|
|
|
|
.. Enter additional parameters for the storage class as desired.
|
|
|
|
. Click *Create* to create the storage class.
