running selenium chrome browser in docker container - selenium

Question

I am trying to use selenium chrome driver with docker. Unfortunately I can't get it working. When I do docker-compose up to launch the container it crashes with a
"container_name exited with code 1" error.
Using docker logs -t -f I was able to get the below error.
selenium.common.exceptions.WebDriverException:
Message: unknown error: Chrome failed to start: exited abnormally
I know that there have been other stack overflow posts about this issue, but all the solutions involve adding chrome options. I have already tried adding various chrome driver options without any luck. See code below.
options = webdriver.ChromeOptions()
options.add_argument('--proxy-server=socks5://localhost:9050')
options.add_argument('disable-infobars')
options.add_argument('--disable-extensions')
options.add_argument('--no-sandbox')
options.add_argument('--disable-setuid-sandbox')
options.add_argument('--headless')
options.add_argument('--start-maximized')
options.add_argument('window-size=1200x800')
options.add_argument('--disable-gpu')
driver = webdriver.Chrome(options=options, desired_capabilities=caps)
I have tried various combinations of the above code with no luck. I also tried commenting out the 'proxy=server' option and running the container, but I get the same error. When I run the normal python code it works without any errors.
Below is the relevant portion of my Dockerfile.
# Extra suff chrome driver needs
RUN apt-get install -y libglib2.0-0=2.50.3-2 \

ENV PATH $CHROMEDRIVER_DIR:$PATH

You're facing an incompatibility between the chromedriver and chrome browser versions being used.
Here are the two lines in question:
RUN apt-get install -y google-chrome-stable
The above means that you'll download the latest chrome browser.
ENV CHROMEDRIVER_VERSION 2.19
However, over here you're specifically using ChromeDriver v2.19, which is a really old version.
You'll need to use compatible versions, which can generally be found in the release notes:
