Docker容器中的Selenium WebDriverException：消息：连接被拒绝

我正在用Selenium + python + firefox做POC，很快我必须用chrometesting一下。

请参考我的github： https ： //github.com/jauyzed/selenium-firefox-python

仅供参考：我没有提交所有必需的文件

当我运行容器时，我看到以下错误：

Traceback (most recent call last): File "/root/selenium_wd_tests/google_test_ff.py", line 10, in setUp self.driver = webdriver.Firefox() File "/usr/local/lib/python2.7/distpackages/selenium/webdriver/firefox/webdriver.py", line 145, in __init__ keep_alive=True) File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 92, in __init__ self.start_session(desired_capabilities, browser_profile) File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 179, in start_session response = self.execute(Command.NEW_SESSION, capabilities) File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/webdriver.py", line 236, in execute self.error_handler.check_response(response) File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/remote/errorhandler.py", line 192, in check_response raise exception_class(message, screen, stacktrace) WebDriverException: Message: connection refused 

在这里发现了一些OP，但没有答案。

任何想法的人？
