On the selected cluster, select the Machine pools tab.
Click the Options menu at the end of the machine pool that you want to enable autoscaling for and select Scale.
On the Edit node count dialog, select the Enable autoscaling checkbox.
Select Apply to save these changes and enable autoscaling for the cluster.
