v3.0.0 does not work in google cloud funtions node10 runtime

Tell us about your environment:

• Puppeteer version: 3.0.0
• Platform / OS version: GCP functions
• URLs (if applicable):
• Node.js version: 10 (beta - in cloud functions)

I see that the latest release 3.0.0 does not support node8 anymore. So, I changed the runtime to 10 (beta) in my cloud functions and got this below error in the logs

Failed to launch the browser process! /workspace/node_modules/puppeteer/.local-chromium/linux-737027/chrome-linux/chrome: error while loading shared libraries: libgbm.so.1: cannot open shared object file: No such file or directory

I tried puppeteer v2.1.1 with node10 runtime and it worked.

Hi, I’m a PM on Google Cloud.

All OS packages available in Cloud Functions are listed on this page, libgbm1 is indeed not listed.

I will follow up with the Cloud Functions team to add it (internal bug number: 156270284)

I’d like to share a somehow-dirty-but-working fix, hoping it might help people like me that would like to try newer versions of Chromium on GCF (Google Cloud Functions) without waiting for the platform’s update.

It’s known from this page that the Node.js 8 & 10 environments on GCF use Ubuntu 18.04, on which the libgbm.so.1 binary is provided by package libgbm1.

By analyzing the package dependencies, examining the list of system packages of the Node.js environment on GCF, and some live inspection of the function execution environment, it’s known that there are (only) two additional packages that we need: libgbm1 and libwayland-server0.

Due to privilege limits we may not install system packages directly. However it’s okay to fetch the binaries at function deployment time (via npm’s pre/post script hooks) and explicitly ask the dynamic linker to use such binaries (via the LD_LIBRARY_PATH environment variable).

Please find below the proof-of-concept code that works for me (using the nodejs10 runtime):

$ cat package.json
{
  "name": "test",
  "main": "index.js",
  "dependencies": {
    "puppeteer": "3.1.0"
  },
  "scripts": {
    "postinstall": "for i in '1618226adb967b34670a06b6c9c28552717dfe0f434b9c6d7639144138948516 http://mirrors.kernel.org/ubuntu/pool/main/m/mesa/libgbm1_19.2.8-0ubuntu0~18.04.3_amd64.deb' '4f5cf9735170083aceb3d0c65ae64848102e9ef0aa0126effafcaf100f0f476c http://mirrors.kernel.org/ubuntu/pool/main/w/wayland/libwayland-server0_1.16.0-1ubuntu1.1~18.04.3_amd64.deb'; do wget ${i#* } && echo ${i% *} ${i##*/} | sha256sum -c && dpkg-deb -X ${i##*/} ./tmpdeb; done && cp ./tmpdeb/usr/lib/x86_64-linux-gnu/lib*.so* ./node_modules/puppeteer/.local-chromium/linux-*/chrome-linux/"
  }
}

$ cat index.js 
module.exports.render = async (req, res) => {
  const puppeteer = require('puppeteer');
  const browser = await puppeteer.launch({
    'env': {
      'LD_LIBRARY_PATH': puppeteer.executablePath().replace(/[^/]+$/, ''),
    },
    'dumpio': true,
  });
  const page = await browser.newPage();
  await page.goto('http://httpbin.org/get');
  res.status(200).send(await page.content());
  await page.close();
  await browser.close();
};

The checksum values above are obtained from the respective package pages: libgdm1 / libwayland-server0.
