The best way to use selenium in a docker container you need to do followings.

Your need to add next lines to your Dockerfile

# install google chrome
RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
RUN sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list'
RUN apt-get -y update
RUN apt-get install -y google-chrome-stable

# install chromedriver
RUN apt-get install -yqq unzip
RUN wget -O /tmp/chromedriver.zip http://chromedriver.storage.googleapis.com/`curl -sS chromedriver.storage.googleapis.com/LATEST_RELEASE`/chromedriver_linux64.zip
RUN unzip /tmp/chromedriver.zip chromedriver -d /usr/local/bin/

# set display port to avoid crash
ENV DISPLAY=:99

# install selenium
RUN pip install selenium==3.8.0

Then your code should be like this. Especially you need to declare your driver like below:

from selenium import webdriver
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--window-size=1420,1080')
chrome_options.add_argument('--headless')
chrome_options.add_argument('--disable-gpu')
driver = webdriver.Chrome(chrome_options=chrome_options)

driver.get('www.google.com')
screenshot = driver.save_screenshot('test.png')
driver.quit()
