Cannot Access IP and PORT on kubernetes minikube

Question

I have created web deployment and service on kubernetes When i list the service with $ kubectl get service command to list IP and Port to access the webpage but when i try to access it the site cant be reached. It seem if kubernetes on minikube didnt pull image from docker hub..

Here my example script.. I use Kubernetes v1.19.2 with default driver Docker 19.03.8

$ kubectl create -f web-pets.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: web
spec:
  replicas: 1
  selector:
    matchLabels:
      app: pets
      service: web
  template:
    metadata:
      labels:
        app: pets
        service: web
    spec:
      containers:
      - image: nginx:alpine-1.19.2
        name: web
        ports:
        - containerPort: 80
          protocol: TCP
---
apiVersion: v1
kind: Service
metadata:
  name: web
spec:
  type: NodePort
  ports:
  - port: 80
    protocol: TCP
  selector:
    app: pets
    service: web

Output create web-pets.yaml

$ kubectl create -f web-pets.yaml
deployment.apps/web created
service/web created

Output $ kubectl get service

$ kubectl get service

Nginx listens on port 80. Hence you need to use port 80 instead of port 3000 in the deployment and service. From the docs you should be able to access it using minikube service web
