Variables

var (

Functions

func NewUnidlerProxier

func NewUnidlerProxier(loadBalancer userspace.LoadBalancer, listenIP net.IP, iptables iptables.Interface, exec utilexec.Interface, pr utilnet.PortRange, syncPeriod, minSyncPeriod, udpIdleTimeout time.Duration, nodePortAddresses []string, signaler NeedPodsSignaler) (*userspace.Proxier, error)

NewUnidlerProxier creates a new Proxier for the given LoadBalancer and address which fires off unidling signals connections and traffic. It is intended to be used as one half of a HybridProxier.

Types

type NeedPodsSignaler

type NeedPodsSignaler interface {
	// NeedPods signals that endpoint addresses are needed in order to
	// service a traffic coming to the given service and port
	NeedPods(serviceName types.NamespacedName, port string) error
}

func NewEventSignaler

func NewEventSignaler(eventRecorder record.EventRecorder) NeedPodsSignaler

NewEventSignaler constructs a NeedPodsSignaler which signals by recording an event for the service with the "NeedPods" reason.
