如何制作Dockerfile？

Question

我需要一个 dockerfile 来运行我的 python脚本。该脚本使用 Selenium ，因此我需要为其加载驱动程序才能正常工作。一个普通的.exe文件 - 驱动程序不合适，因此，根据脚本所在的托管管理员的建议，我需要创建一个dockerfile，以使脚本正常工作。

主要问题是我根本无法运行脚本，因为我不明白如何在服务器上加载所需的驱动程序。

这是dockerfile中应该是什么的示例代码。

FROM python:3

RUN apt-get update -y
RUN apt-get install -y wget
RUN wget -O $HOME/geckodriver.tar.gz https://github.com/mozilla/geckodriver/releases/download/v0.23.0/geckodriver-v0.23.0-linux64.tar.gz
RUN tar xf $HOME/geckodriver.tar.gz -C $HOME
RUN cp $HOME/geckodriver /usr/local/bin/geckodriver
RUN chmod +x /usr/local/bin/geckodriver
RUN rm -f $HOME/geckodriver $HOME/geckodriver.tar.gz

这是python脚本中使用的代码

options = Options()
options.add_argument('headless')
options.add_argument('window-size=1920x935')

driver = webdriver.Chrome(options=options, executable_path=r"chromedriver.exe")

driver.get(f"https://www.wildberries.ru/catalog/{id}/feedbacks?imtId={imt_id}")
time.sleep(5)
big_stat = driver.find_element(by=By.CLASS_NAME, value="rating-product__numb")

我可以重做此代码段，以使其在Firefox上工作，如有必要。

为了使硒使用Dockerfile与Python合作，这是现有的

有关使用它的说明，请参阅Realme 。

对于构建，基本上是这样：

非Apple M1 Mac：

docker build -t seleniumbase .

如果在Apple M1 Mac上运行，请改用：

docker build --platform linux/amd64 seleniumbase .

在构建DockerFile之前，您需要克隆 seleniumbase 。

这是Dockerfile当前的样子：
