Option 2: Deploy Rok Disk Manager Manually

If you want to deploy Rok Disk Manager manually, follow the instructions below.

Procedure

1. Go to your GitOps repository, inside your rok-tools management environment:

   

   root@rok-tools:~# cd ~/ops/deployments

2. Create the Rok namespaces, rok and rok-system, that will host Rok and its system components:

   

   root@rok-tools:~/ops/deployments# rok-deploy --apply rok/rok-namespaces/overlays/deploy

3. Edit the kustomization manifest. Choose one of the following options, based on your cloud provider:

   AWS

   Azure

   Google Cloud

   Edit rok/rok-disk-manager/overlays/deploy/kustomization.yaml to use the eks overlay as base:

   

   bases: - ../eks # <-- Edit this line to point to the eks overlay

   Edit rok/rok-disk-manager/overlays/deploy/kustomization.yaml to use the aks overlay as base:

   

   bases: - ../aks # <-- Edit this line to point to the aks overlay

   Edit rok/rok-disk-manager/overlays/deploy/kustomization.yaml to use the gke overlay as base:

   

   bases: - ../gke # <-- Edit this line to point to the gke overlay

4. Commit your changes:

   

   root@rok-tools:~/ops/deployments# git commit -am "Deploy Rok Disk Manager"

5. Deploy RDM:

   

   root@rok-tools:~/ops/deployments# rok-deploy \ > --apply rok/rok-disk-manager/overlays/deploy

Verify

1. From inside your management environment, verify that the Rok Disk Manager Pods are up-and-running. Check the Pod status and verify that field STATUS is Running and field READY is 1/1 for all Pods:

   

   root@rok-tools:~# kubectl -n rok-system get pods NAME READY STATUS RESTARTS AGE rok-disk-manager-tmwqz 1/1 Running 0 1m rok-disk-manager-c4w7n 1/1 Running 0 1m

   Note

   The number of Pods you are seeing in the above output should be equal with the number of nodes you have in your cluster.

Summary

You have successfully deployed Rok Disk Manager.
