Types ¶
type LoadBalancer ¶
type LoadBalancer interface { // NextEndpoint returns the endpoint to handle a request for the given // service-port and source address. NextEndpoint(service ServicePortName, srcAddr net.Addr) (string, error) NewService(service ServicePortName, sessionAffinityType api.AffinityType, stickyMaxAgeMinutes int) error CleanupStaleStickySessions(service ServicePortName) }
LoadBalancer is an interface for distributing incoming requests to service endpoints.
type LoadBalancerRR ¶
type LoadBalancerRR struct {
// contains filtered or unexported fields
}
LoadBalancerRR is a round-robin load balancer.
func NewLoadBalancerRR ¶
func NewLoadBalancerRR() *LoadBalancerRR
NewLoadBalancerRR returns a new LoadBalancerRR.
func (*LoadBalancerRR) CleanupStaleStickySessions ¶ added in v0.8.2
func (lb *LoadBalancerRR) CleanupStaleStickySessions(svcPort ServicePortName)
func (*LoadBalancerRR) NewService ¶ added in v0.8.2
func (lb *LoadBalancerRR) NewService(svcPort ServicePortName, affinityType api.AffinityType, ttlMinutes int) error
func (*LoadBalancerRR) NextEndpoint ¶
func (lb *LoadBalancerRR) NextEndpoint(svcPort ServicePortName, srcAddr net.Addr) (string, error)
NextEndpoint returns a service endpoint. The service endpoint is chosen using the round-robin algorithm.
func (*LoadBalancerRR) OnUpdate ¶
func (lb *LoadBalancerRR) OnUpdate(allEndpoints []api.Endpoints)
OnUpdate manages the registered service endpoints. Registered endpoints are updated if found in the update set or unregistered if missing from the update set.
type Proxier ¶
type Proxier struct {
// contains filtered or unexported fields
}
Proxier is a simple proxy for TCP connections between a localhost:lport and services that provide the actual implementations.
func CreateProxier ¶ added in v0.13.1
func NewProxier ¶
NewProxier returns a new Proxier given a LoadBalancer and an address on which to listen. Because of the iptables logic, It is assumed that there is only a single Proxier active on a machine.
type ServicePortName ¶ added in v0.15.0
type ServicePortName struct { types.NamespacedName Port string }
ServicePortName carries a namespace + name + portname. This is the unique identfier for a load-balanced service.
func (ServicePortName) String ¶ added in v0.15.0
func (spn ServicePortName) String() string
