+DaemonSets, Deployments, HorizontalPodAutoscalers, Ingress, Jobs and ReplicaSets are enabled by default.
 Other extensions resources can be enabled by setting runtime-config on
 apiserver. runtime-config accepts comma separated values. For ex: to disable deployments and jobs, set
 `--runtime-config=extensions/v1beta1/deployments=false,extensions/v1beta1/jobs=false`
