func BuildGenericConfig

func BuildGenericConfig(
	s options.CompletedOptions,

func CreatePeerEndpointLeaseReconciler

func CreatePeerEndpointLeaseReconciler(c genericapiserver.Config, storageFactory serverstorage.StorageFactory) (reconcilers.PeerEndpointLeaseReconciler, error)

CreatePeerEndpointLeaseReconciler creates a apiserver endpoint lease reconciliation loop The peer endpoint leases are used to find network locations of apiservers for peer proxy

func CreateProxyTransport

func CreateProxyTransport() *http.Transport

CreateProxyTransport creates the dialer infrastructure to connect to the nodes.

func DefaultGenericAPIServicePriorities

func DefaultGenericAPIServicePriorities() map[schema.GroupVersion]APIServicePriority

DefaultGenericAPIServicePriorities returns the APIService priorities for generic APIs

Types

type APIServicePriority

type APIServicePriority struct {
	// Group indicates the order of the group relative to other groups.
	Group int32
	// Version indicates the relative order of the Version inside of its group.
	Version int32
}

APIServicePriority defines group priority that is used in discovery. This controls group position in the kubectl output.

type CompletedConfig

type CompletedConfig struct {
	// contains filtered or unexported fields
}

CompletedConfig embeds a private pointer that cannot be instantiated outside of this package

func (*CompletedConfig) GenericStorageProviders

func (c *CompletedConfig) GenericStorageProviders(discovery discovery.DiscoveryInterface) ([]RESTStorageProvider, error)

GenericStorageProviders returns a set of APIs for a generic control plane. They ought to be a subset of those served by kube-apiserver.

func (CompletedConfig) New

func (c CompletedConfig) New(name string, delegationTarget genericapiserver.DelegationTarget) (*Server, error)

New returns a new instance of Master from the given config. Certain config fields will be set to a default value if unset. Certain config fields must be specified, including: KubeletClientConfig

func (*CompletedConfig) NewCoreGenericConfig

func (c *CompletedConfig) NewCoreGenericConfig() *corerest.GenericConfig

NewCoreGenericConfig returns a new core rest generic config.

type Config

type Config struct {
	Generic *genericapiserver.Config

	PeerEndpointReconcileInterval time.Duration
	// PeerEndpointLeaseReconciler updates the peer endpoint leases
	PeerEndpointLeaseReconciler peerreconcilers.PeerEndpointLeaseReconciler
	// PeerAdvertiseAddress is the IP for this kube-apiserver which is used by peer apiservers to route a request
	// to this apiserver. This happens in cases where the peer is not able to serve the request due to
	// version skew. If unset, AdvertiseAddress/BindAddress will be used.
	PeerAdvertiseAddress peerreconcilers.PeerAdvertiseAddress
