我已经遇到了很多问题来运行Docker容器。现在它正在运行,下一个问题促使我在这里提出一个问题:为什么Chrome不能在Docker容器中启动?
server.js文件看起来像这样:

const express = require('express');
const puppeteer = require('puppeteer');

const app = express();

app.get('/screenshot', async (req, res) => {
    console.log('Taking screenshot');
    const browser = await puppeteer.launch({
        headless: true,
        // executablePath: '/opt/homebrew/bin/chromium',
        // executablePath: 'google-chrome-stable',
        // executablePath: '/usr/bin/chromium-browser',
        executablePath: '/opt/google/chrome/google-chrome',
        args: ['--no-sandbox', '--headless' ],
        timeout: 300000,
    });
    console.log('started browser');
    const page = await browser.newPage();
    console.log('opened new page');
    await page.goto('https://www.google.com');
    console.log('went to google');
    const imageBuffer = await page.screenshot();
    console.log('took screenshot');
    await browser.close();
    console.log('closed browser');

    res.set('Content-Type', 'image/png');
    res.send(imageBuffer);
    console.log('Screenshot taken');
});

app.listen(3000, () => {
    console.log('Listening on port 3000');
});

Dockerfile:

FROM node:slim

# We don't need the standalone Chromium

package.json:

    "version": "1.0.0",
    "description": "Headless Chrome Node.js server in Docker",
    "main": "server.js",

        "start": "node server.js"
    },
    "dependencies": {
        "express": "^4.18.2",
        "puppeteer": "^20.1.2"
    }
}

控制台错误:

The Docker Container builds and runs successfully but times out after calling localhost:3000/screenshot with following error:

有没有人知道如何解决这个问题?

我正在使用M2的MacBook Pro,所以我必须在Docker设置中激活Rosetta的使用,现在它正在工作。
