hi!
My issue :
I use Kong as API gateway and Consul as a service discovery. Now i have 3 same services running on different random ports (for example user-service on port 44000 , 44001,44002).
As i know consul has DNS interface.
I want to be able to send 3 requests to kong (for example http://127.0.0.1:8000/user-route/{here_name_of_request_mapping_in_my_controller}) and take response from 3 different services.
Can someone explain please or refer to place where i can start?
Sorry if this question is stupid) i’m learning. Thanks!
@hbagdi , Hello!
thanks a lot for your quick response 
i’ve done it . I want to leave comment how. maybe it will be helpful for someone.
1)install and run consul
2)register services with it (i made it with simple adding consul-discovery dependency in my pom.xml)
3) open kong.conf and define dns_resolver = 127.0.0.1:8600 ( By default, Consul will listen on 127.0.0.1:8600 for DNS queries in the consul. domain)
4) create Service with Admin API (host should be like {your-service-name}.service.consul). port can be any. specify path (for me it was simple “/”)
5) create Route for this service (define client host (for me it was my local machine - so localhost)) and paths (i made it /ss).
6) By default Kong listens to 8000 port so
i made get request to http://127.0.01:8000/ss/loadbalance (where /loadbalance - request mapping for my method in controller) with header “Host : 127.0.0.1”
7) now it use round robin load balancer
p.s .
I want to clarify.
Just imagine that i have 100 microservices ( i think it possible) . And each of this microservices have own API with 5 methods for example.
So i should use 100 calls to Admin API and set Routes and Services for each service ???
i used api gateway from spring cloud stack and i was able to route request by easily typing
http://localhost:(port_of_api_gateway)/(name_of_service_which_i_want_to_route)/(name_of_request_mapping)
Yes. It should be trivial to write a script to automate this.
