我正在尝试使用readinessprobe和livenessprobe在kubernetes中设置yaml和minikube

我的应用已公开并且可以正常运行，但是当我尝试<ip>:<port>/healthz时，它说

  

无法获取/ healthz

这是我的server.js，运行GET请求，检查liveness和readiness

'use strict';

const express = require('express');

// Constants
const PORT = 8080;
const HOST = '0.0.0.0';

// App
const app = express();
app.get('/',(req,res) => {
  res.send('Hello world\n');
});

// App
const app = express();
app.get('/healthz',res) => {
  res.send('fine');
});

app.listen(PORT,HOST);
console.log(`Running on http://${HOST}:${PORT}`);

这是我的deployment.yaml文件

但是它不起作用，如何将livenessprobe吊舱指向我的部署，以便它可以使吊舱/部署状态正常。
