Kapacitor k8sAutoscale Node

I was hoping for some guidance on examples and usage for the k8sAutoscale node.

I have tried the example from this link: GitHub - influxdata/k8s-kapacitor-autoscale: Demonstration of using Kapacitor to autoscale a k8s deployment

I followed everything, but for some reason the example does not autocale. Also, it has not been maintained in two years, so I was hoping for a more recent example.

Some of the errors I get frequently are:
cannot use the k8sAutoscale node, could not create kubernetes client: unknown kubernetes cluster "minikube", cannot get client

However, when running the example, I never had to specify the cluster name using the .cluster() method.

Any help in writing even a simple TICKscript would be greatly appreciated!
