I have been breaking my head trying to understand what the issue is, it shows the following error message:

error parsing feedback.yaml: error converting YAML to JSON: yaml: line 10: mapping values are not allowed in this context

apiVersion: v1
kind: Service
metadata:
   name: feedback
   labels:

I have checked it using a yaml validator and also checked the spacing, am I missing something?

This was a weird one. Turns out your hyphens were the wrong type :) all your instances of - were actually – (see the difference? one's longer).

Here's a working file:

apiVersion: v1
kind: Service
metadata:
  name: feedback
  labels:
    run: feedback
spec:
  ports:
    - port: 80
      targetPort: 3000
      protocol: TCP
  type: NodePort
  selector:
    run: feedback

Side note: this is definitely not node.js – please tag as kubernetes
