I am trying to change the sync period as mentioned in the following k8s document. I found the file named kube-controller-manager.yaml in /etc/kubernetes/manifests. I changed the timeoutSeconds: value from 15 secs(default) to 60 secs. Now I have 2 questions based on above info:

• 1. Is this the right way to change the sync period ? Cause I have read in the document that there is some flag named --horizontal-pod-autoscaler-sync-period, but adding that is also not working.
• 2. And any changes made to the file kube-controller-manager.yaml are getting restored to default whenever I restart the minikube? what should I do? Please let me know any solution or any view in this.
