Storage Classes

Manage Storage Classes

A StorageClass supplies users a method to detail the type of “classes” offered. Each StorageClass has a provider that determines what type of volume plugin utilized for provisioning a persistent volume. To get to this tab, click on the Storage > Storage Classes tab.

Before installing an application that requires storage, we should create a StorageClass. This can be created via the Platform9 Storage Class dashboard.

Add Storage Class

Step 1.

Navigate to Storage > Storage Classes menu and click Add Storage Class.

Step 2.

Select the cluster, then name the storage class

Step 3.

Choose an installed CSI driver or choose a new CSI driver, then click Next .

Step 4.

A new review window opens where we can review the configuration to ensure it matches the example StorageClass YAML file for a CSI Hostpath Driver noted below.

apiVersion: storage.k8s.io/v1

kind: StorageClass

metadata:

  name: hostpath-csi-sc

  annotations:

    storageclass.kubernetes.io/is-default-class: 'false'

  labels:

    kubernetes.io/cluster-service: 'true'

provisioner: kubernetes.io/hostpath.csi.k8s.io

The YAML file is created based on the parameters specified in the initial Configure Storage Class screen. Users can now edit the YAML file and append any additional parameters needed, based on the storage class type. If everything is finished, click the Complete button.

The newly added storage class can now be used for deploying persistent storage for your applications on this cluster. See @

Edit a Storage Class

The Storage > Storage Class (link) YAML displays the YAML file that is created based on user specified parameters which can be edited to include any additional parameters if required, based on the storage class type. You can modify a storage class for a cluster by going to the YAML file, making any needed changes, and then clicking save.

Delete Storage Class

To delete a storage class, follow the steps provided below.

Step 1.

Navigate to Storage Classesmenu and select the storage classes to delete from the grid.

Step 2.

Next, click Delete. A warning is displayed and if so desired, click the Delete Storage Classes button to permanently delete the selected storage classes.
