Types

type Config

type Config struct {
	EtcdClientConfig etcd.ClientConfig
	CaCert           string
	CaKey            string
	APIServer        *url.URL
	KubeletID        string
	CloudProvider    string
	KubeVersion      string
	MasterCount      uint
	PodNetworkCidr   string
}

Config represents runtime params cfg structure.

type SharedAssets

type SharedAssets struct {
	FrontProxyCa    string
	FrontProxyCaKey string
	SaPub           string
	SaKey           string
}

SharedAssets - the data to be shared between all kubernetes masters
