unifiedControlPlaneImage: ""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
