Learn KOP - Managed Storage - Rafay Product Documentation
Part 2: Blueprint
What Will You Do
This is Part 2 of a multi-part, self-paced quick start exercise. In this part, you will apply the "default-upstream" blueprint which contains the managed storage addon to the cluster. By applying the blueprint, you will be installing Rook-Ceph into the cluster.
Apply Blueprint
First, you will apply the "default-upstream" blueprint to the cluster.
- In the console, navigate to your project
- Select Infrastructure -> Clusters
- Click the gear icon on the cluster card
- Select "Update Blueprint"
- Select "default-upstream" for the blueprint
- Select the latest version
- Click "Save and Publish"
The blueprint will begin to be applied to the cluster.
After a few minutes, the cluster will be updated to the new blueprint.
- Click "Exit"
Validate Add-On
Now, you will validate the Rook Ceph managed system add-on is running on the cluster.
In the console, navigate to your project
Select Infrastructure -> Clusters
Click the cluster name on the cluster card
Click the "Resources" tab
Select "Pods" in the left hand pane
Select "rafay-infra" from the "Namespace" dropdown
Enter "rook-ceph-tools" into the search box
Click the "Actions" button
Select "Shell and Logs"
Click the "Exec" icon to open a shell into the container
Enter the following command in the shell to check the status of the Ceph cluster
ceph status
Now, you will confirm the nodes in the cluster have a the storage devices controlled by Ceph.
- Open a shell within each node in the cluster
- Execute the following command to list all block devices
lsblk -a
The output of the command should show the previously viewed raw devices now with a Ceph partitions.

Now, you will view the storage classes created by Rook Ceph in the cluster
- In the console, navigate to your project
- Select Infrastructure -> Clusters
- Click "kubectl" on the cluster card
- Enter the following command
kubectl get storageclasses
You will see the three Rook Ceph storage classes that were created. Each of classes maps to a particular type of storage being exposed (block, file and object).
Recap
At this point, you have the blueprint with the Rook Ceph managed system add-on configured and deployed to the cluster.
