How to use one loadbalancer for exposing two deployments in two different node pool?

I have two docker images that run on two different node pools. Api runs on say node-pool-a, Api-legacy runs on node-pool-b.

Now I wanted to access both via same loadbalancer using this snippet.

apiVersion: v1
kind: Service
  name: api-service
    app: api
    - name: api
      port: 8000
      targetPort: 8000
    - name: api-legacy
      port: 1883
      targetPort: 1883
  type: LoadBalancer

But I notice I can use selector for one deployment. Help!

Hi there,

Load balancers can listen on multiple ports, but they can only point at one backend service.

You’ll need to put something like ingress-nginx behind the load balancer to route traffic for different domains to different services:
