awsRegion missing in example. It's not working without it. And added cloudProvider setting. It's by default "aws" and not necessary at the moment. But it's to important and should be defined if default will change in the future.

Autoscaling
Autoscaling of worker nodes can be easily enabled by setting the autoscaling_enabled variable to true for a worker group in the worker_groups map.
This will add the required tags to the autoscaling group for the cluster-autoscaler.
One should also set protect_from_scale_in to true for such worker groups, to ensure that cluster-autoscaler is solely responsible for scaling events.
You will also need to install the cluster-autoscaler into your cluster. The easiest way to do this is with helm.
The helm chart for the cluster-autoscaler requires some specific settings to work in an EKS cluster. These settings are supplied via YAML values file when installing the helm chart. Here is an example values file:
rbac:
create: true
sslCertPath: /etc/ssl/certs/ca-bundle.crt
cloudProvider: aws
awsRegion: YOUR_AWS_REGION
autoDiscovery:
clusterName: YOUR_CLUSTER_NAME
enabled: true
To install the chart, simply run helm with the --values option:
helm install stable/cluster-autoscaler --values=path/to/your/values-file.yaml
