示例1: AddInstanceListener
func (da *DemoApp) AddInstanceListener(event controller.Event) {
if event.Type() != controller.AddInstanceEventType {
panic("")
}
e := event.(*controller.AddInstanceEvent)
for _, r := range da.Controller.Routers {
instance := e.Instance
port, ok := ServicePortMap[instance.Service]
if !ok {
log.Println("Unknown port for service:", instance.Service)
continue
}
// TODO: debugging, delete it
if r.Id() == "rr" {
port = ":8081"
}
err := r.AddService(instance.Service, port, rIdPolicyMap[r.Id()])
if err != nil {
log.Println(err)
}
err = r.AddServiceInstance(instance.Service, instance)
if err != nil {
log.Println(err)
}
}
}示例2: FailureInstanceListener
func (da *DemoApp) FailureInstanceListener(event controller.Event) {
if event.Type() != controller.FailureInstanceEventType {
panic("")
}
e := event.(*controller.FailureInstanceEvent)
log.Printf("Failure Instance: '%v', '%v'\n", e.Reporter, e.Instance)

for _, r := range da.Controller.Routers {
instance := e.Instance
err := r.RemoveServiceInstance(instance.Service, instance)
if err != nil {
log.Println(err)
}
}
}
}示例3: AddInstanceListener
// AddInstanceListener makes the Load Balancer know of the newly added service instance.
// It adds the service instances to the routers it knew.
// TODO: It assumes the new instance is newly created: which means no other router had it before.
func (lb *LoadBalancer) AddInstanceListener(event controller.Event) {
if event.Type() != controller.AddInstanceEventType {
panic("")
}
e := event.(*controller.AddInstanceEvent)
for _, r := range lb.Controller.Routers {
instance := e.Instance
port, ok := ServicePortMap[instance.Service]
if !ok {
log.Println("Unknown port for service:", instance.Service)
continue
}
err := r.AddService(instance.Service, port, router.NewRoundRobinPolicy())
if err != nil {
log.Println(err)
}
err = r.AddServiceInstance(instance.Service, instance)
if err != nil {
log.Println(err)
}
}
}示例4: AddRouterListener
// AddRouterListener makes the Load Balancer know of the newly added router.
// It adds known service instances to the router and set service policy as round robin.
// TODO: It assumes the new router is newly created: which means it has no services.
func (lb *LoadBalancer) AddRouterListener(event controller.Event) {
if event.Type() != controller.AddRouterEventType {
panic("")
}

continue
}

log.Println(err)
}
for _, instance := range instances {

if event.Type() != controller.FailureInstanceEventType {
panic("")
}
e := event.(*controller.FailureInstanceEvent)
log.Printf("Failure Instance: '%v', '%v'", e.Reporter, e.Instance)
}示例6: RmInstanceListener
func (da *DemoApp) RmInstanceListener(event controller.Event) {
if event.Type() != controller.RmInstanceEventType {
panic("")
}
e := event.(*controller.RmInstanceEvent)
for _, r := range da.Controller.Routers {
