Chromeless docker container

[voltcode]

It would be great to quickly spin up a farm of chromeless images to run a test suite in parallel. Using containers would remove the AWS requirement for scalability. I'm not a docker expert, just started to evaluate docker-based solution as our test suite has grown significantly in the last couple of months, and we need a more elastic approach.

I can make a PR for something similar to this Dockerfile. It works in my extremely limited testing. Should it go in the examples folder?

@voltcode https://github.com/joelgriffith/browserless#usage-with-chromeless may works!

how can this dockerfile work you don't even install chromeless in it?

So after MANY days of searching I'm finally unable to run my Chromeless script in Docker. Here is the dockerfile I use:

FROM ubuntu:16.04
WORKDIR /app
RUN apt-get update
RUN apt-get install curl -y

# Install Node.js
RUN curl -sL https://deb.nodesource.com/setup_8.x | bash
RUN apt-get install --yes nodejs wget dos2unix udev ttf-freefont
RUN node -v
RUN npm -v

# install chromeless
COPY package.json /app/package.json
RUN npm install chromeless

#INSTALL CHROME:
RUN \
  wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - && \
  echo "deb http://dl.google.com/linux/chrome/deb/ stable main" > /etc/apt/sources.list.d/google.list && \
  apt-get update && \
  apt-get install -y google-chrome-stable && \
rm -rf /var/lib/apt/lists/*

Just build this image docker build -t chromeless-image ., and run it with docker run -it -v yourpath:/app chromeless-image /bin/bash, with yourscript.js in yourpath. Then you just need to launch Chrome google-chrome --headless --remote-debugging-port=9222 --disable-gpu --no-sandbox & before launching your chromeless script node yourscript.js and it should be fine.

It's not working 100% though. I have found that when trying to access some websites (which ones exactly I don't know) I run into the errors

[1104/111344.440167:ERROR:bus.cc(394)] Failed to connect to the bus: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory
[1104/111344.440313:WARNING:property.cc(149)] DaemonVersion: GetAndBlock: failed.
ALSA lib confmisc.c:768:(parse_card) cannot find card '0'

and a bunch of other errors. I have no idea where these errors are coming from.
