Variables

var MasterStaticFiles = []*StaticFile{
	{

MasterStaticFiles Put static files here, can be moved to all master nodes before kubeadm execution

Types

type CommandType

type CommandType string

const InitMaster CommandType = "initMaster"

const JoinMaster CommandType = "joinMaster"

const JoinNode CommandType = "joinNode"

type Config

type Config struct {
	Vlog         int
	VIP          string
	RegistryInfo registry.Info

	KubeadmConfigFromClusterFile kubeadm.KubeadmConfig
	APIServerDomain              string
	// contains filtered or unexported fields
}

type Runtime

type Runtime struct {
	Config *Config
	// contains filtered or unexported fields
