Kubernetes: How to create ingress type networkpolicy to allow only access to labeled pods

I have the following deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  creationTimestamp: null
  labels:
    app: redis
  name: redis
spec:
  replicas: 1
  selector:
    matchLabels:
      app: redis
  strategy: {}
  template:
    metadata:
      creationTimestamp: null
      labels:
        app: redis
    spec:
      containers:
      - image: redis:alpine
        name: redis
        resources: {}
status: {}

Question 1 : How do you expose this deployment via a ClusterIP service on port 8080.

Question 2 : How would I create a new Ingress Type NetworkPolicy to allows only the pods with label access=redis to access the deployment.
