Docker + puppeteer + nodejs + chrome

Question

我的代码有错误，期待您的帮助！ 我正在编写一个测试 puppeteer，它会自动进入 nodejs 上的站点（代码有效），但是当我保存它并在 Docker 中运行它时，它根本不起作用（chrome 无法启动）。 任何帮助都会让我开心！ 我们希望得到您的帮助！！

代码js

const puppeteer = require('puppeteer-core');
const download = require('image-downloader');
const fs = require('fs');
const express = require("express");



// buildPaths.js
const { buildPathHtml, buildPathPdf } = require('./buildPaths');
(async() => {
    const browser = await puppeteer.launch({        
    executablePath: 'C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe',
    headless: false,
    slowMo:300,
    args: [
        //'--auto-open-devtools-for-tabs',
        '--disable-dev-shm-usage',
        '--no-sandbox',
        '--disable-setuid-sandbox'
    ]
    });    
    console.log('Browser openned');
    const page = await browser.newPage();
    // dịnh dạng khung cửa sổ hiển thị
   // page.setViewport({ width: 1280, height: 926 });
   try{
  const pageURL =  await page.goto('http://kenh14.vn/', {waitUntil: 'networkidle2', timeout: 0});
    console.log('Page loaded');
    console.log(`opened the page: ${pageURL}`);
   }catch(error){
       console.log(`failed to open the page: ${pageURL} with the error: ${error}`);
   }

如果您不使用卷绑定，则无法在容器内部访问主机文件。

尝试通过

绑定chrome文件夹

docker run -v C:\\Program Files (x86)\\Google\\Chrome\\Application:/opt/chrome .

所以将-v C:\\Program Files (x86)\\Google\\Chrome\\Application:/opt/chrome 添加到您的 docker run 中。（类似地，您可以使用 docker-compose volume 选项）

然后使用“/opt/chrome/chrome.exe”作为executablePath
