Автоматизируйте e2e-тестирование с помощью selenium приложения Django в gitlab cicd -Error: selenium.common.exceptions.WebDriverException: neterror?e=dnsNotFound

Вот вывод моего cicd pipline, который не работает

Вот мой Dockerfile:

Вот мой .gitlab-ci.yml. на этапе сборки все работает нормально и передается. Проблема возникает в моем run_e2e_test. Я не знаю, где у меня ошибка. Я предполагаю, что проблема в том, как я определяю псевдонимы для служб, но я не знаю, как эти службы могут взаимодействовать друг с другом:

Вот мой тестовый файл: Как только мой код выполняется в gitlab cicd pipeline, тесты e2e не работают:

        super().setUp()
        if "CI" in os.environ.keys():

            self.driver = webdriver.Remote(
                command_executor="http://selenium:4444", options=options
            )
        else:
            subprocess.Popen(["python", "manage.py", "runserver"])
            time.sleep(5)

Я пробовал несколько разных способов, но так и не смог заставить их работать. Локально тесты selenium работают отлично, но я не могу автоматизировать их в своем конвейере.
