f.service.md network policy example does not block the service

[askrht]

In the exercise for applying a network policy, the command a busybox without the label also return nginx home page.

kubectl run busybox --image=busybox --rm -it --restart=Never -- wget -O- http://nginx:80                       # This should not work but it works fine

kubectl run busybox --image=busybox --rm -it --restart=Never --labels=access=true -- wget -O- http://nginx:80  # This should be fine

I am using the latest minikube in Ubuntu 16.04

$ kubectl version

Are you using a network provider that supports Network Policy on your Minikube cluster? Check here for reference.
I'll update the exercise for clarity

Feel free to re-open if you think issue is unresolved :)

No need. It worked after I followed your hint and added Cilium to my minikube on Ubuntu 16.04. Commands below

minikube stop; minikube delete; rm -rf ~/.minikube # will reset minikube completely
curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
chmod +x minikube && sudo mv minikube /usr/local/bin/
minikube start --network-plugin=cni --memory=4096
kubectl create -f https://raw.githubusercontent.com/cilium/cilium/v1.5/examples/kubernetes/1.14/cilium-minikube.yaml
