Using headless Chrome Puppeteer with meteor and mup (Error)

[Twisterking]

Mup version (mup --version): 1.4.5

So I am running into an error with my deployed Meteor app:

/built_app/programs/server/npm/node_modules/puppeteer/.local-chromium/linux-571375/chrome-linux/chrome: error while loading shared libraries: libX11-xcb.so.1: cannot open shared object file: No such file or directory

I am 90% sure, that this is just due to some missing libs inside the abernix/meteord:node-8-base docker container? Any ideas on this?

Do I have to make my own docker container with some more libs installed? (see here: https://github.com/GoogleChrome/puppeteer/issues/404 - apt-get install libpangocairo-1.0-0 libx11-xcb1 libxcomposite1 libxcursor1 libxdamage1 libxi6 libxtst6 libnss3 libcups2 libxss1 libxrandr2 libgconf2-4 libasound2 libatk1.0-0 libgtk-3-0).

Or is there some way around this?

Mup is able to customize the docker container: http://meteor-up.com/docs#customize-docker-image. You could use that to install the apt-get packages.

Im trying to figure this out as well.

I have successfully used buildInstructions toapt-get install the required dependencies. However a runaway amount of Chrome processes are created. The solution recommended by Puppeteer is to add these instructions to your docker file.

https://github.com/GoogleChrome/puppeteer/blob/master/docs/troubleshooting.md#running-puppeteer-in-docker

But I cant figure out if these commands are possible with meteor-up especially the last 4.

Could you provide any assistance?

[Twisterking]

Not sure if this is of any help to you but I ended up using pm2-meteor for my worker as I don't need docker there - using my PR.

Has anybody been able to successfully get Puppeteer working with mup?

Hi @IDCOLL , I have build 2 custom docker images based on meteord with 8.11.2 node version https://hub.docker.com/r/nabiltntn/meteord-node-with-chromium/tags

8.11.2_dumb-init starts the application with dumb-init to avoid having plenty of zombies process after browser execution.

Thank you for the quick reply. Do I just reference that docker image in my MUP file i.e. or do I need to do add some instructions to the build Instructions also?

Also is the image compatible with Meteor 1.6+

docker: { image: '8.11.2_dumb-init', buildInstructions: [ 'RUN apt-get update && apt-get install -y imagemagick' ] }

[nabiltntn]

You need to change the image. No addtional build instructions.

Meteor 1.6 is compatible with Node 8, so it should work fine.

Thanks @nabiltntn it worked.

I had to make a small adjustment in my puppeteer code: await puppeteer.launch({headless: true, args:['--no-sandbox']}) The --no-sandbox argument is critical otherwise PUPPETEER will give the following error:

Exception while invoking method 'createXreport' Error: Failed to launch chrome! [82.196.3.225][0219/140956.079200:ERROR:zygote_host_impl_linux.cc(89)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

[nabiltntn]

Yes i usally use :

const browser = await puppeteer.launch({
      args: [
        '--no-sandbox',
        '--disable-setuid-sandbox',
        '--disable-webgl',
        '--disable-accelerated-2d-canvas',
        '--disable-gpu'
      ]
    });

Hi @nabiltntn, thank you very much for your docker images with Chromium!

I've used them to automate production of pre-rendered landing pages with in-line critical css. See my post in the Meteor forums: https://forums.meteor.com/t/pre-rendered-landing-pages-with-critical-css/50626

@wildhart thanks for the reference

Hi @nabiltntn, thank you for your the previous docker images that you've provided. I recently upgraded my Meteor project to 1.9. Can you help or explain/direct to me how I can create a custom docker image based on meteord with 12.14.0 node version.

[nabiltntn]

Unfortunately, I don't have anymore the docker file I have used to build the image but I tried to recreate it again for node 12 using image layers from Dockerhub

Could you try to build the following Dockerfile

FROM meteord:node-12.14.0-base

RUN apt-get update \
    && apt-get install -y \
    libpangocairo-1.0-0 \
    libx11-xcb1 \
    libxcomposite1 \
    libxcursor1 \
    libxdamage1 \
    libxi6 \
    libxtst6 \
    libnss3 \
    libcups2 \
    libxss1 \
    libxrandr2 \
    libgconf2-4 \
    libasound2 \
    libatk1.0-0 \
    libgtk-3-0 \
    wget \
    --no-install-recommends \
    && rm -rf /var/lib/apt/lists/* \
    && rm -rf /src/*.deb

RUN wget -O /usr/local/bin/dumb-init https://github.com/Yelp/dumb-init/releases/download/v1.2.2/dumb-init_1.2.2_amd64

RUN chmod +x /usr/local/bin/dumb-init

ENTRYPOINT ["/bin/bash" "-c" "/usr/local/bin/dumb-init -- $METEORD_DIR/run_app.sh"]

Hope this help !

Thanks @nabiltntn for the feedback. I was able to get it working by cloning the https://github.com/abernix/meteord repo and made changes to the 'base' Dockerfile and built it. I can confirm that it works with my Meteor 1.9 project.

I modified the Dockerfile to this:

Awesome work @johannel00. Can you make this available on DockerHub?

It's available here. Let me know if it works for you. https://hub.docker.com/repository/docker/fedescoinc/meteord-node-with-chromium_dumb-init/tags

Works perfectly, thanks!

FYI, After upgrading to Meteor 2.3.2 with node 14 I got this working with just:
