# Install Google Chrome
RUN curl -sS -o - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add \
    && echo "deb https://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list \
    && apt-get -y update \
    && apt-get -y install google-chrome-stable
# Install ChromeDriver
RUN wget -N https://chromedriver.storage.googleapis.com/80.0.3987.106/chromedriver_linux64.zip -P ~/ \
    && unzip ~/chromedriver_linux64.zip -d ~/ \
    && rm ~/chromedriver_linux64.zip \
    && mv -f ~/chromedriver /usr/local/bin/chromedriver \
