Nightmare.js with Docker

Question

I'm attempting to run Nightmare.js on the server. I'm well aware that it's headless on Linux, and requires xvfb. What I don't understand is why I continue to get the following error when in DEBUG mode:

  nightmare queuing process start +0ms
  nightmare queueing action "useragent" +3ms
  nightmare queueing action "goto" for https://news.ycombinator.com +2ms
  nightmare queueing action "cookies" +1ms
  nightmare queueing action "goto" for https://news.ycombinator.com/login +0ms

  nightmare electron child process exited with code 2: undefined +25ms

Here's my Dockerfile:

FROM node:latest

RUN apt-get update &&\
    apt-get install -y \
    xvfb \
    x11-xkb-utils \
    xfonts-100dpi \
    xfonts-75dpi \
    xfonts-scalable \
    xfonts-cyrillic \
    x11-apps \
    clang \
    libdbus-1-dev \
    libgtk2.0-dev \
    libnotify-dev \
    libgnome-keyring-dev \
    libgconf2-dev \
    libasound2-dev \
    libcap-dev \
    libcups2-dev \
    libxtst-dev \
    libxss1 \
    libnss3-dev \
    gcc-multilib \
    g++-multilib

RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

COPY . /usr/src/app

RUN npm install

CMD DEBUG=nightmare* xvfb-run --server-args="-screen 0 1024x768x24" node tux.js -s hn -m create -p 11878025

Any thoughts? Help would be greatly appreciated.

Answer 1

What you can do is to put all your files in a subdirectory, say app/ and in your Dockerfile do:

ADD app/ /usr/src/app/

of course in your app folder there will be env.sh, package.json, tux.js and the lib directory

That way if you need to add more files, you wont have to add them manually in your dockerfile.

PS: It works with COPY too
