Your help will be highly appreciated.
From the Kubernetes docs:
Kubernetes 1.11 and later, the default configuration can be printed out using the kubeadm config print command. It is recommended that you migrate your old v1alpha3 configuration to v1beta1 using the kubeadm config migrate command, because v1alpha3 will be removed in Kubernetes 1.14.
From Kubernetes ver 1.13 onwards v1alpha3 has been deprecated. You need to change the apiVersion to v1beta1
kubeadm config migrate --old-config config.yaml
