Unable to get Angular to work on a local domain

I am trying to bring up angular application on custom local domain blog.dev. The angular application is working fine of https://localhost:4200. But on the blog.dev domain, it is not working.

My angular 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: 4200
      nodePort: 31000

The nginx.conf is given below

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 host file entry is given below

127.0.5.1 blog.dev

I am using minikube

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

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;
    }
      }
    }
