title: Error when running Headless Chrome in Jenkins Docker using puppeteer
body: <p>I run Jenkins in Docker(Debian9) to test Angular 7 app by using ChromeHeadless browser.
  I've the following in karma.conf.js</p>
  
  <pre><code>process.env.CHROME_BIN = require('puppeteer').executablePath()
   karmaConfig.customLaunchers = {
        ChromeHeadlessCI: {
          base: 'ChromeHeadless',
          flags: ['--no-sandbox',
                  '--disable-setuid-sandbox',
                  '--disable-gpu']
        }
      };
  </code></pre>
  
  <p>I've installed the following in my Docker:</p>
  
  <pre><code>RUN apt-get install -yq  libc6-i386 libXss1 gconf-service libasound2 libatk1.0-0 libc6 libcairo2 libcups2 libdbus-1-3 libexpat1 libfontconfig1 libgcc1 libgconf-2-4 libgdk-pixbuf2.0-0 libglib2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libpangocairo-1.0-0 libstdc++6 libx11-6 libx11-xcb1 libxcb1 libxcomposite1 libxcursor1 libxdamage1 libxext6 libxfixes3 libxi6 libxrandr2 libxrender1 libxss1 libxtst6 ca-certificates fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils wget
  </code></pre>
  
  <p>When running the tests in Jenkins I get the following:</p>
  
  <pre><code> [39mChromeHeadless stderr: /var/jenkins_home/workspace/new-sample-
  project/node_modules/puppeteer/.local-chromium/linux-662092/chrome-linux/chrome:
   error while loading shared libraries: libX11.so.6: cannot open shared object
   file: No such file or directory
  </code></pre>
  
  <p>I don't know what the problem is? Is it related to the installed packages in Debain? What should I do?</p>
