Krakend Eureka

An Eureka client and subscriber for the KrakenD framework.

Build the example

Go 1.8 is a requirement

$ make

Using Eureka client

	eurekaClient, err := eureka.New(ctx, serviceConfig.ExtraConfig)
	if err != nil {
		log.Fatal("ERROR:", err.Error())
	}

	routerFactory := krakendgin.NewFactory(krakendgin.Config{
		Engine:         gin.Default(),
		Middlewares:    []gin.HandlerFunc{},
		Logger:         logger,
		HandlerFactory: krakendgin.EndpointHandler,
		ProxyFactory: customProxyFactory{
			logger,
			proxy.DefaultFactoryWithSubscriber(logger, eureka.SubscriberFactory(ctx, eurekaClient)),
		},
	})

Registering your application in Eureka

eurekaClient.Register("krakend-gw", GetLocalIP(), serviceConfig.Port)

krakend-eureka's Issues

Update of Eureka Instances doesn't work

Hi,

I've applied the plugin to the source code of KrakenD as it's explained in the example and
the registration to Eureka Server happens without no issue but the update of the eureka instances doesn't.

When I open the code of subscriber.go inside an editor, it says that the goroutine inside the loop() function is unreachable,
in fact nothing is printed in the console(there is a fmt.Println("LOOP") inside the goroutine in question), so i can easy understand that the gorutine is never executed and the instances of eureka are never updated.
