Installing phantomjs with node in docker

Question

I'm trying to install the phantomjs executable in /usr/local/bin in a docker container, alongside node. I think I'm almost there, but I'm pretty new to docker and not well versed in installing binaries or working with Linux so struggling to work out where I'm going wrong.

This is my docker file:

FROM        node:6.4-onbuild

# Install phantomjs
WORKDIR     ~
RUN         apt-get install libfreetype6 libfreetype6-dev \
            && apt-get install libfontconfig1 libfontconfig1-dev
RUN         export PHANTOM_JS="phantomjs-2.1.1-linux-i686" \
            && wget https://bitbucket.org/ariya/phantomjs/downloads/$PHANTOM_JS.tar.bz2 \
            && tar xvjf $PHANTOM_JS.tar.bz2 \
            && mv $PHANTOM_JS /usr/local/share \
            && ln -sf /usr/local/share/$PHANTOM_JS/bin/phantomjs /usr/local/bin

WORKDIR     /usr/src/app
RUN         npm run build
EXPOSE      8080
CMD         ["node", "./bin/start.js"]

I've run bash on the container and there is definitely something called phantomjs in /usr/local/bin but I'm assuming that I've linked the wrong thing or it's an invalid executable. I'm thrown an error from my application telling me that there is no phantomjs executable in /usr/local/bin.

Can anyone give me a few pointers? Happy to provide more details if you post a comment.

There's an existing image for this already on Docker hub using the following Dockerfile:

FROM debian:jessie 
  MAINTAINER Werner Beroux <[email protected]> 
  # 1. Install runtime dependencies 
  # 2. Install official PhantomJS release 
  # 3. Clean up 

  RUN apt-get update \
      && apt-get install -y --no-install-recommends \
          ca-certificates \
          bzip2 \
          libfontconfig \
      && apt-get clean \
      && rm -rf /var/lib/apt/lists/*
  
  RUN apt-get update \
      && apt-get install -y --no-install-recommends \
          curl \
      && mkdir /tmp/phantomjs \
      && curl -L https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-2.1.1-linux-x86_64.tar.bz2 \
              | tar -xj --strip-components=1 -C /tmp/phantomjs \
      && cd /tmp/phantomjs \
      && mv bin/phantomjs /usr/local/bin \
      && cd \
      && apt-get purge --auto-remove -y \
          curl \
      && apt-get clean \
      && rm -rf /tmp/* /var/lib/apt/lists/*
  
  # Run as non-root user 
  RUN useradd --system --uid 72379 -m --shell /usr/sbin/nologin phantomjs
  
  USER phantomjs 
  EXPOSE 8910 
  CMD ["/usr/local/bin/phantomjs"]
