node 应用:
const http = require('http');
const server = http.createServer((req, res) => {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello, World!\n');
});
server.listen(3000, () => {
console.log('Server running at http://localhost:3000/');
});

containerPort能不能和NodeJS应用的端口不同，在这种情况下是3000？
