I am running git lab ci cd pipeline for selenium Python UI automated tests. My tests are passing ok on my local. I have initialized Google Chrome using below code

driver = chromedriver_autoinstaller.install()
options = webdriver.ChromeOptions()
prefs = {'profile.default_content_setting_values.automatic_downloads': 1}
options.add_experimental_option("prefs", prefs)
driver = webdriver.Chrome(options=options)

When I am running GitLab job, my pipeline is failing with below error

enter image description here

Below if the GitLab runner I can see used while running : enter image description here

I also tried to used remote driver and headless mode- In headless mode most of tests are failing. In remote mode, it not instantiating driver. Remove driver code as below

elif self.browser == 'remote':
driver = webdriver.Remote(options=webdriver.ChromeOptions(), command_executor='http://selenium__standalone-chrome:4444/wd/hub')

I am not sure if its happening due to gitlab runner. Or Do I need to create my custom gitlab runner to run on specific machine. I am running selenium UI tests , so not sure runner which is used in my case don't have facility to run in GUI mode.

I found similar issue here- WebDriverException: Message: unknown error: Chrome failed to start: crashed error using ChromeDriver Chrome through Selenium Python on Amazon Linux

Tried below code but still same issue

    options = Options()
    options.binary_location = '/usr/bin/google-chrome'
    driver = webdriver.Chrome(options=options, 
    executable_path='/usr/local/bin/chromedriver')

I am spinning image with -Docker executor with image joyzoursky/python-chromedriver:3.8

Probably you are missing below options:

    options = webdriver.ChromeOptions()
    options.add_argument('--no-sandbox')
    options.add_argument('--disable-dev-shm-usage')

For more inspirations go to: WebDriverException: unknown error: DevToolsActivePort file doesn't exist while trying to initiate Chrome Browser
