Download files without dialog window selenium

I have a cod.

@pytest.fixture(scope="function")
def browser():
    selenium_grid_url = os.getenv('SELENIUM_HOST', "not_found") + "/wd/hub"
    chrome_options = webdriver.ChromeOptions()
    chrome_options.add_experimental_option('prefs', {'intl.accept_languages': 'ru-RU',
                                                     'download.default_directory': f'{directory}',
                                                     "download.prompt_for_download": False,
                                                     "download.directory_upgrade": True,
                                                     "safebrowsing.enabled": True
                                                     }
                                           )
    print(f"nStart Chrome browser.. {selenium_grid_url}")
    capabilities = DesiredCapabilities.CHROME
    browser = webdriver.Remote(desired_capabilities=capabilities, command_executor=selenium_grid_url,
                               options=chrome_options)
    yield browser
    print("nClose Chrome..")
    browser.quit()

I have a docker + python + pytest + selenium + Chrome + selenium host and prefs But it doesn’t work. I want save to file without dialog window. But test don`t save files. How can I understand the reason? And… Downloading files works on Windows, but not docker on linux. P.S I have this path in docker env for chrome download and python DOWNLOAD_FOLDER=/app/download_files FOLDER_FOR_TEST_FILES=/app/test_files

My cod for check files

new_list_download_files = next(os.walk(f'{directory}'))[2]
        first_doc = new_list_download_files[0]
        second_doc = new_list_download_files[1]

Dockerfile

FROM python:3.8.12-buster

ENV PYTHONUNBUFFERED 1

ARG REQUIREMENTS=${REQUIREMENTS:-requirements.txt}
COPY ./${REQUIREMENTS} /requirements.txt
RUN pip install -r requirements.txt

RUN mkdir /app
COPY . /app
WORKDIR /app

ENTRYPOINT  ["python"]

Answer

After 5 days. In the end, all you had to do was use docker-volumes. In docker-compose.yml

volumes:
  data-volume:
  download-volume:
    external: true
    name: selenium_downloads
