Testing Shell

#kdebugn opens a temp shell
kubectl run shell --pod-running-timeout 600s --rm -i --tty --image nicolaka/netshoot -- /bin/sh -c bash 

# ping
ping __VM_IP__

# test plain HTTP (if app is running or not)
curl __VM_IP__
curl demo-vm.vm-demo.svc.cluster.local
curl demo-vm
# test again after SVC Apply
curl demo-vm
curl demo-vm.vm-demo.svc.cluster.local

# apply ingress and check
curl http://demo-vm.kubev.kkp.demo.kubermatic.io
