An example kube-proxy config file is needed

When installing kubernetes 1.7.2 and a warning about kube proxy appears

WARNING: all flags other than --config, --write-config-to, and --cleanup-iptables are deprecated. Please begin using a config file ASAP.

      

        
        
        
      

    

So I am trying to make my own config file, for example

{
  "bind-address": "10.110.200.42",
  "hostname-override": "10.110.200.42",
  "cluster-cidr": "172.30.0.0/16",
  "logtostderr": true,
  "v": 0,
  "allow-privileged": true,
  "master": "http://10.110.200.42:8080",
  "etcd-servers": "http://10.110.200.42:2379"
}

      

        
        
        
      

    

but i still get the error

error: Object 'apiVersion' is missing in '{

      

        
        
        
      

    

I feel like I need an example config file, but I searched for it without any results, even searched for source code in git, I didn't find anything useful, please help!

ps, I found a way to generate an example file, just use the command --write-config-to on the command line, example below
