I want to use docker to run selenium tests within a jenkins instance. To test this, I am creating a docker image with the following Dockerfile:
FROM python:2.7-slim
WORKDIR /selenium
ADD . /selenium
# Install any needed packages specified in requirements.txt
RUN pip install --trusted-host pypi.python.org -r requirements.txt
# Install some basic stuff
RUN apt-get update -qqy
RUN apt-get install -y wget xvfb bzip2 zip unzip
# Install all the chrome libraries...
RUN apt-get install -y gconf-service libasound2 libatk1.0-0 libcairo2 libcups2 libfontconfig1 libgdk-pixbuf2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libxss1 fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils
# Set firefox version and installation directory through environment variables.
ENV FIREFOX_VERSION 45.0
ENV FIREFOX_DIR /usr/bin/firefox
ENV FIREFOX_FILENAME $FIREFOX_DIR/firefox.tar.bz2
# Download the firefox of specified version from Mozilla and untar it.
RUN mkdir -p $FIREFOX_DIR
RUN wget -q --continue --output-document $FIREFOX_FILENAME "https://ftp.mozilla.org/pub/firefox/releases/${FIREFOX_VERSION}/linux-x86_64/en-US/firefox-${FIREFOX_VERSION}.tar.bz2"
RUN tar -xaf "$FIREFOX_FILENAME" --strip-components=1 --directory "$FIREFOX_DIR"
# Prepend firefox dir to PATH
ENV PATH $FIREFOX_DIR:$PATH
# Install Chrome
ENV LOCALEXE /usr/local/bin
ENV CHROMEDRIVERZIP=chromedriver_linux64.zip
ENV CHROMEDRIVER=chromedriver
RUN wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
RUN dpkg -i google-chrome-stable_current_amd64.deb; apt-get -fy install
RUN wget "http://chromedriver.storage.googleapis.com/2.33/${CHROMEDRIVERZIP}"
RUN unzip ${CHROMEDRIVERZIP}
RUN mv ${CHROMEDRIVER} ${LOCALEXE}
# Prepare the output directories
RUN mkdir -p /selenium/out
RUN ln -sf /dev/stdout /selenium/out/out.log
RUN ln -sf /dev/stderr /selenium/out/err.log
RUN Xvfb :99 -ac -screen 0 1280x1024x16 &
ENV DISPLAY :99
# Run app.py when the container launches
CMD ["nosetests", "-s", "test1.py"]
and in the actual test file (test1.py) I also have the lines
from pyvirtualdisplay import Display
display = Display(visible=0, size=(800, 800))
display.start()
before I create the selenium webdriver, based on suggestions from here and here and here. However, after having created the docker image and running it with the following commands
docker run --rm selenium1
docker run --rm -e DISPLAY=$DISPLAY selenium1
docker run --rm -e DISPLAY=$DISPLAY -v /tmp/.X11-unix:/tmp/.X11-unix selenium1
I always get the following error:
Traceback (most recent call last):

How to fix it? How to make sure I can use chrome (and firefox) for selenium tests in a docker container?
