I would like to run Istio to play around, but I facing issues with my local kubernetes installation and I am successfuly stack with a way of debug my installation
That is a my current situation:

Unfortunately, after I read out most of documentation, I found out only few way to debug an installation
journalctl -r -u kubelet
kubectl get events
kubectl describe deployment
Is there any common workflow to debug Kubernetes installation?
