How to configure The Kubernetes Blueprint to Scale out with vRA 7.1

In this guide I will show you how to enable the new Scale out/in feature introduced in vRealize Automation 7.1 to allow your end users to scale their Kubernetes deployment in the portal. Let’s get started!

Pre-Reqs

An installation of vRealize Automation 7.1 or higher – Enterprise Edition
A reservation with a static IP pool.
The Kuberenetes Blueprint installed and entitled see my guide here.
A quiet place where you will not be interrupted see my guide here.

Let’s add the new scale entitlements

Click administration Tab
Catalog Management
Then click entitlments
Select the entilment you want to add to
Click edit

Click the + next to Entitled Items

Add the scale actions

Select the Scale in action
Select the Scale out action
Click OK

Now click finish

Now fire off a new Kubernetes Blueprint

Note this may take several minutes.

Once deployed, get the IP address of the Master Node

Notice in vRA 7.1 you can see the IP addresses now! Cool hugh?

Open an SSH session to the master and type the following to list the current nodes.

Notice there are only two nodes, we will scale up the deployment to add another node

kubectl get nodes

Scale out the Kubernetes deployment

Highlight the Kubernetes Deployement in the items view tab
Click Actions
Click Scale Out

Now add additional nodes to scale out

Click to select the minion node
Click up to how many nodes you want to add
Click Submit

Confirm the scale out and click OK

Once complete you should see a new node in your deployment

Now go back to your SSH session on the Master and list nodes with the following command again

Enjoy your Kubernetes as a Service Blueprint now with Scale out built in!
