我创建了两个服务，每个服务都有相应的部署。所有这些都在同一个PC。应用YAML后，服务和部署都正常运行。

sudo npm kubectl apply -f deployment.yaml

现在，如果我尝试卷曲到入口IP地址，那么我得到404页未找到作为响应。

sudo kubectl get ingress -o wide
sudo curl <IP address of ingress>

如果我尝试curl到员工服务或员工部署的IP地址，它会给出连接在等待一段时间后被拒绝。我为员工服务和部署提到的任何端口我尝试，我总是得到错误而不是正确的响应。

社区有人能帮忙吗？我需要从员工pod调用myshop pod的/emplistendpoint。

myshop. js

const express = require('express')
const app = express()
const port = 3000

app.get('/emplist', (req, res) => {
    res.status(200).send( empListObj )
});

app.listen(port, '0.0.0.0', () => {
  console.log(`Listening on port ${port}`)
})

js

const axios = require('axios').default;

const express = require('express')
const app = express()
const port = 3001

app.get('/', (req, res) => {
  
  axios({
      method: 'get',
      url: 'http://myshopservice/emplist'
    })
    .then(function (response) {
        res.status(200).send(response.data.empList)
    })
    .catch(function (error) {
        res.status(200).send(`Error because ${error}`);
    })
})

app.listen(port, '0.0.0.0', () => {
  console.log(`Listening on port ${port}`)
})

现在对应的部署. yaml是：
