before usage

  1. you should pass --no-sandbox, --disable-setuid-sandbox args when launch browser
const puppeteer = require('puppeteer');

(async() => {

    const browser = await puppeteer.launch({
        args: [
            '--no-sandbox',
            '--disable-setuid-sandbox'
        ]
    });

    const page = await browser.newPage();

    await page.goto('https://www.google.com/', {waitUntil: 'networkidle2'});

    browser.close();

})();
  1. if you got page crash with BUS_ADRERR (chromium issue), increase shm-size on docker run with --shm-size argument
docker run --shm-size 1G --rm -v <path_to_script>:/app/index.js alekzonder/puppeteer:latest
  1. If you're seeing random navigation errors (unreachable url) it's likely due to ipv6 being enabled in docker. Navigation errors are caused by ERR_NETWORK_CHANGED (-21) in chromium. Disable ipv6 in your container using --sysctl net.ipv6.conf.all.disable_ipv6=1 to fix:
docker run --shm-size 1G --sysctl net.ipv6.conf.all.disable_ipv6=1 --rm -v <path_to_script>:/app/index.js alekzonder/puppeteer:latest
  1. add --enable-logging for chrome debug logging http://www.chromium.org/for-testers/enable-logging
const puppeteer = require('puppeteer');

(async() => {

    const browser = await puppeteer.launch({args: [
        '--no-sandbox',
        '--disable-setuid-sandbox',

        // debug logging
        '--enable-logging', '--v=1'
    ]});
