further i found that problem caused by following line to api-server start.

please tell me if anything wrong with this. after api-server starts kube controller and scheduler trying to start then they go to crashbackloop state then api-server restarting. when i removed above line it is working perfegctly.

@pgnaleen :wave: This issue sounds more like a request for support and less like an issue specifically for docs. I encourage you to bring your question to the #kubernetes-users channel in Kubernetes slack. You can also search resources like Stack Overflow for answers to similar questions.
