Types ¶
type LoadBalancer ¶
type LoadBalancer interface {
// NextEndpoint returns the endpoint to handle a request for the given
// service and source address.
NextEndpoint(service string, srcAddr net.Addr) (string, error)
}
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) NextEndpoint ¶
NextEndpoint returns a service endpoint. The service endpoint is chosen using the round-robin algorithm.
func (*LoadBalancerRR) OnUpdate ¶
func (lb *LoadBalancerRR) OnUpdate(endpoints []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 NewProxier ¶
func NewProxier(loadBalancer LoadBalancer, listenAddress net.IP, iptables iptables.Interface) *Proxier
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.
