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
metadata:
name: api-service
spec:
selector:
app: api
ports:
- 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:

Hope that this helps!
