title: kubeadm init --apiserver-advertise-address flag equivalent in config file
body: <p>I need to initialize my kubernetes cluster using a kubeadm config file due to some extra arguments that I need to pass, which are not directly available to <code>kubeadm init</code>.</p>
  
  <p>I did create a config file and it works fine. I went throgh the <a href="https://godoc.org/k8s.io/kubernetes/cmd/kubeadm/app/apis/kubeadm/v1beta2" rel="nofollow noreferrer">documentation</a> of the kubeadm config file but still not able to get which option is equivalent to the command line flag <code>--apiserver-advertise-address</code></p>
  
  <p>My kubeadm version is <code>1.15.7</code></p>
  
  <p>This is my current config:
  Commented out lines are the options which I already tried but dosen't seem to work. </p>
