Use service discovery

registry service

...

instance := discovery.NewInstance(discovery.GenRandomId(), "demo.test.com", map[string]string{discoverry.SchemaHttp: "127.0.0.1:17000"})
instance.Id = "test_id_1"

  //gokeeper server address（grpc address）
  "127.0.0.1:7001",
  //registry service
  discovery.WithRegistry(instance),
  discovery.WithRegistryTTL(60*time.Second),
	//schedule strategy，default：random
  discovery.WithScheduler(map[string]schedule.Scheduler{
    "demo.test.com": schedule.NewRoundRobinScheduler(),
  }),
)

discovery service

import(

...


//start gokeeper client

//get service address
