Fails to run kubeadm init

With reference to https://github.com/kubernetes/kubeadm/issues/1239. How do I configure and start the latest kubeadm successfully?

kubeadm_new.config is generated by config migration:
kubeadm config migrate --old-config kubeadm_default.config --new-config kubeadm_new.config. Content of kubeadm_new.config:

I changed "kubernetesVersion: v1.12.2" in kubeadm_new.config and it seems to progress further and now stuck at the following error:

failed to run Kubelet: Running with swap on is not supported, please disable swap! or set --fail-swap-on flag to false.

How do I set fail-swap-on to FALSE to get it going?

Kubeadm comes with a command which prints default configuration, so you can check each of the assigned default values with:
kubeadm config print-default

In your case, if you want to disable swap check in the kubelet, you have to add the following lines to your current kubeadm config:

---

apiVersion: kubelet.config.k8s.io/v1beta1

kind: KubeletConfiguration

failSwapOn: false
