    I was able to resolve the issue. Things that were done to resolve the issue

    1. nginx config file was changed as follows:

       worker_processes  1;

 events {
   worker_connections  1024;
 }

 http {
   server {
     listen 80;
     server_name  localhost;

     root   /usr/share/nginx/html;
     index  index.html index.htm;
     include /etc/nginx/mime.types;

     gzip on;
     gzip_min_length 1000;
     gzip_proxied expired no-cache no-store private auth;
     gzip_types text/plain text/css application/json 
     application/javascript 
     application/x-javascript text/xml application/xml 
     application/xml+rss 
     text/javascript;

 location / {
   try_files $uri $uri/ /index.html;
 }
   }
 }

    The deployment file is given below

    apiVersion: apps/v1
kind: Deployment
metadata: 
  name: client-depl
spec: 
  replicas: 1
  selector: 
    matchLabels:
      app: client
  template: 
    metadata:
      labels:
        app: client 
    spec:
      containers:
        - name: client
          image: pinakinc/client
          ports:
          - containerPort: 4200
---
apiVersion: v1
kind: Service
metadata:
  name: client-srv
spec:
  selector:
    app: client
  type: LoadBalancer
  ports: 
    - name: client
      protocol: TCP
      port: 80
      targetPort: 80
      nodePort: 32000

  2. 0

    Your application running on port 4200 so the target port should be 4200 in service also.

    So traffic flow like service port 80 > target port 4200 > container port 4200

    Target point and container port should get matched.

    - name: client
          image: pinakinc/client
          ports:
          - containerPort: 4200
---
apiVersion: v1
kind: Service
metadata:
  name: client-srv
spec:
  selector:
    app: client
  type: LoadBalancer
  ports: 
    - name: client
      protocol: TCP
      port: 80
      targetPort: 4200
      nodePort: 31000
