Types

type FakeServiceHealthServer

type FakeServiceHealthServer struct{}

FakeServiceHealthServer is a fake ServiceHealthServer for test programs

func (FakeServiceHealthServer) SyncEndpoints

func (fake FakeServiceHealthServer) SyncEndpoints(_ map[types.NamespacedName]int) error

SyncEndpoints is part of ServiceHealthServer

func (FakeServiceHealthServer) SyncServices

func (fake FakeServiceHealthServer) SyncServices(_ map[types.NamespacedName]uint16) error

SyncServices is part of ServiceHealthServer

type ServiceHealthServer

type ServiceHealthServer interface {
	// Make the new set of services be active.  Services that were open before
	// will be closed.  Services that are new will be opened.  Service that
	// existed and are in the new set will be left alone.  The value of the map
	// is the healthcheck-port to listen on.
	SyncServices(newServices map[types.NamespacedName]uint16) error
	// Make the new set of endpoints be active.  Endpoints for services that do
	// not exist will be dropped.  The value of the map is the number of
	// endpoints the service has on this node.
	SyncEndpoints(newEndpoints map[types.NamespacedName]int) error
}

ServiceHealthServer serves HTTP endpoints for each service name, with results based on the endpoints. If there are 0 endpoints for a service, it returns a 503 "Service Unavailable" error (telling LBs not to use this node). If there are 1 or more endpoints, it returns a 200 "OK".
