var KubeadmExtraArgsWhitelist = map[int][]string{
	KubeadmCmdParam: {
		"ignore-preflight-errors",
		"dry-run",

}

KubeadmExtraArgsWhitelist is a whitelist of supported kubeadm params that can be supplied to kubeadm through minikube's ExtraArgs parameter. The list is split into two parts - params that can be supplied as flags on the command line and params that have to be inserted into the kubeadm config file. This is because of a kubeadm constraint which allows only certain params to be provided from the command line when the --config parameter is specified

var KubeadmYamlPath = path.Join(vmpath.GuestEphemeralDir, "kubeadm.yaml")

KubeadmYamlPath is the path to the kubeadm configuration

var SkipAdditionalPreflights = map[string][]string{}

SkipAdditionalPreflights are additional preflights we skip depending on the runtime in use.
