无法在 Docker 容器中运行 Selenium 脚本

Question

我一直在尝试在 Docker 容器中运行 Selenium 脚本。我在尝试运行脚本时收到以下错误：

我查看了 Stack Overflow 上的各种帖子来查找此错误，并将我的 Python 代码更改为以下内容：

def scrape_reviews(product_url):
    chrome_path='/usr/bin/google-chrome'
    filename='daraz_reviews.csv'
    #open the browser
    #service = Service(executable_path=path)
    options = webdriver.ChromeOptions()
    options.binary_location=chrome_path
    options.add_argument("--disable-gpu")
    options.add_argument("--disable-extensions")
    options.add_argument("--disable-infobars")
    options.add_argument("--start-maximized")
    options.add_argument("--disable-notifications")
    options.add_argument('--headless')
    options.add_argument('--no-sandbox')
    options.add_argument('--disable-dev-shm-usage')
    options.add_argument("--disable-setuid-sandbox") 
    browser = webdriver.Chrome(service=ChromeService(ChromeDriverManager().install())) #Error at this line

即使将所有这些选项添加到我的 Python 代码中，我仍然遇到同样的错误。如果有人能帮我解决这个问题，我将不胜感激。

我的 Dockerfile 也如下：

你看过这个吗？ WebDriverException：未知错误：尝试启动 Chrome 浏览器时 DevToolsActivePort 文件不存在
