Constants

const (
	// KubeadmCmdParam is command parameters for kubeadm
	KubeadmCmdParam = iota
	// KubeadmConfigParam is config parameters for kubeadm
	KubeadmConfigParam = iota
)

enum to differentiate kubeadm command line parameters from kubeadm config file parameters (see the KubeadmExtraArgsAllowed variable for more info)

const (
	// KubeletServiceFile is the file for the systemd kubelet.service
	KubeletServiceFile = "/lib/systemd/system/kubelet.service"
	// KubeletSystemdConfFile is config for the systemd kubelet.service
	KubeletSystemdConfFile = "/etc/systemd/system/kubelet.service.d/10-kubeadm.conf"
	// InitRestartWrapper is ...
	InitRestartWrapper = "/etc/init.d/.restart_wrapper.sh"
	// KubeletInitPath is where Sys-V style init script is installed
	KubeletInitPath = "/etc/init.d/kubelet"
)

const (
	Apiserver         = "apiserver"
	ControllerManager = "controller-manager"
	Scheduler         = "scheduler"
	Etcd              = "etcd"

	Kubeproxy         = "kube-proxy"
	Kubelet           = "kubelet"
)

These are the components that can be configured through the "extra-config"

Variables

var KubeadmExtraArgsAllowed = map[int][]string{
	KubeadmCmdParam: {
		"ignore-preflight-errors",
		"dry-run",
		"kubeconfig",
		"kubeconfig-dir",
		"node-name",
		"cri-socket",

	KubeadmConfigParam: {
		"pod-network-cidr",
	},
}

KubeadmExtraArgsAllowed is a list 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 KubeadmExtraConfigOpts = []string{
	Apiserver,
	ControllerManager,
	Scheduler,
	Etcd,
	Kubeadm,
	Kubelet,
	Kubeproxy,
}

KubeadmExtraConfigOpts is a list of allowed "extra-config" components

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

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