The local Kubernetes setup requires some prerequesites and configuration...

1.) Install ingress in your local Docker Desktop Kubernetes instance with something like this:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.8.2/deploy/static/provider/cloud/deploy.yaml
kubectl get pods --all-namespaces -l app.kubernetes.io/name=ingress-nginx --watch

2.) Find out your local hostname (e.g. type hostname in powershell on windows), then replace armstrong02 with your own hostname in the configuration files. Spring Security will redirect unauthenticated requests from a browser to this URL. The configuration under k8s/localhost does the rest of the trick. Your browser can handle your local hostname without problems. But requests inside Kubernetes need to use the IP of host.docker.internal from the inside of pod.
