Try these manifests and remember to deploy an Ingress Controller (I usually use traefik, here some instructions to set it)

service.yml: I changed NodePort to ClusterIP (the default, you can remove the line)

apiVersion: v1
kind: Service
metadata:
  name: auth
spec:
  selector:
    app: auth
    tier: backend
  ports:
    - protocol: TCP
      port: 3000
      targetPort: auth
  type: ClusterIP

ingress.yml: (I set port to 3000, your service port)

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: test-ingress
spec:
  backend:
    serviceName: auth
    servicePort: 3000
