The idea is to be able to test against multiple Kubernetes versions as we do in JOSDK. This currently doesn't work because we need to find a way to expose the minikube internal registry similarly to what is done with KinD. I'd appreciate your help on this if you are familiar with minikube, though that knowledge might not transfer to using the action in CI directly…
