Where are you looking for documentation? The first paragraph of the official doc states that services can load balance:

https://kubernetes.io/docs/concepts/services-networking/service/

If you’re completely new to this, there might be something basic that you’re misunderstanding (happens all the time). Could you share the yaml files you’re using to set up your cluster?

If I were to guess where you might be misunderstanding/misusing things:

1) ingress is used to allow EXTERNAL traffic into your cluster. If you’re trying to do internal comms (node-to-node / service-to-service), you don’t need ingress.

2) Don’t create individual pods. You want to be using deployments: https://kubernetes.io/docs/concepts/workloads/controllers/deployment/

A good experiment setup:

apiVersion: v1
kind: Service
metadata:
  name: hello-world
  labels:
    app: hello-world
spec:
  ports:
    - name: web
      protocol: TCP
      port: 80
      targetPort: 80
  selector:
    app: hello-world
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: hello-world
  labels:
    app: hello-world
spec:
  replicas: 3
  selector:
    matchLabels:
      app: hello-world
  template:
    metadata:
      labels:
        app: hello-world
    spec:
      containers:
      - name: nginx
        image: nginx
        ports:
        - containerPort: 80
          name: http

If this deploys to your cluster, you should then be able to run a pod, and from inside that pod curl http://hello-world should get you the default nginx welcome page.

If this doesn’t work for you, I’ll need more details to be able help.
