localhost didn't send any data. in post service in kubernetes - node.js

Question

I have working on Microservices with Node JS and React (course from udemy) ,
but unfortunately I'm stuck with kubernetes problem
i have created posts-srv service,
posts-srv.yaml
apiVersion: v1
kind: Service
metadata:
name: posts-srv
spec:
type: NodePort
selector:
app: posts
ports:
- name: posts
protocol: TCP
port: 4000
targetPort: 4000
posts.js (index.js)
const { randomBytes } = require('crypto');
const express = require('express')
const cors = require('cors')
const axios = require('axios')
const app = express();
app.use(express.json())
app.use(cors())
const posts = {};
app.get('/test',(req,res)=>
{
res.status(200).json({
success: true
})
})
app.get('/posts',(req,res)=>
{
res.send(posts)
})
app.post('/posts', async (req,res)=>
{
console.log("app.post('/posts',(req,res)=> ")
const id = randomBytes(4).toString('hex');
const {title } = req.body;
posts[id] = {
id,title
};
await axios.post('htt://localhost:4005/events',{
type:'PostCreated',
data:{
id,title
}
});
res.status(201).send(posts[id])
})
app.post('/events',(req,res)=>
{
console.log("received event",req.body.type);
res.send({});
})
app.listen(4000,()=>{
console.log("server started for posts on 4000");
})
and the docker file is
from node:alpine
WORKDIR /app
COPY package.json ./
RUN npm install
COPY ./ ./
CMD ["npm","start"]
then i used the command kubectl apply -f post-srv.yaml and service was successfully created but that is not accessible to my computer using browser
