Configure load balancing using Kong Ingress Controller

1

Hi,
I want to implement load balancing of multiple targets using Kong Ingress Controller. I have Kong installed in Kubernetes environment with KIC. I have created an ingress and service (ExternalName Type) which is pointing to an upstream which is external to the Kubernetes cluster. Below are the configurations -

Ingress -

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: echo
spec:
  rules:
    - http:
        paths:
          - backend:
              service:
                name: my-service
                port:
                  number: 443
            path: /v1/status
            pathType: Exact

Service -

apiVersion: v1
kind: Service
metadata:
  annotations:
    konghq.com/protocol: https
    konghq.com/upstream-policy: demo
  name: my-service
spec:
  externalName: example.com
  ports:
    - port: 443
  type: ExternalName

Below is the KongUpstreamPolicy -

apiVersion: configuration.konghq.com/v1beta1
kind: KongUpstreamPolicy
metadata:
  name: demo
spec:
  hashOn:
    header: x-lb
  hashOnFallback:
    input: ip
  algorithm: consistent-hashing

Here KongUpstreamPolicy is attached to service using annotations.

Where I can give multiple upstream targets in this configuration?

Here service is pointing to only one host but I want to provide multilple hosts which can be load balanced using KongUpstreamPolicy.

@anup.rai Does this document properly cover your question?

@rick - This page talks about a service which is deployed in the same Kubernetes cluster where Kong is deployed. Both Kong pods and service pods are running in same cluster.

My use case is where service is outside of Kong cluster. In this case how can I provide multiple endpoints for load balancing?
