在Python镜像上安装selenium/chromedriver

Question

我正在尝试在我的应用程序的 Python 映像上安装 selenium / chromedriver。我尝试了很多不同的迭代，但似乎没有任何效果。

需求.txt

selenium==4.23.1
webdriver-manager==4.0.2

我使用的是苹果芯片。这是我的 Dockerfile。现在有点混乱，因为我添加了各种依赖项，但似乎没有任何效果。

FROM --platform=linux/amd64 python:3.12-slim

构建镜像，启动容器：

docker build . -t my-image
docker run -it --shm-size=2g my-image

在 Python shell 中：

import time

from selenium import webdriver
from selenium.webdriver.chrome.service import Service
from selenium.webdriver.chrome.options import Options
from webdriver_manager.chrome import ChromeDriverManager

chrome_options = Options()
chrome_options.add_argument("--headless")
chrome_options.add_argument("--no-sandbox")
chrome_options.add_argument("--disable-gpu")
chrome_options.add_argument("--disable-dev-shm-usage")

service = Service(ChromeDriverManager().install())
driver = webdriver.Chrome(service=service, options=chrome_options)

错误是：

尝试将这些依赖项添加到 dockerfile 中：

xvfb \
fonts-liberation \
libappindicator3-1 \
xdg-utils \

如果仍然无法正常工作，可以通过将此配置添加到 chrome 驱动程序来查看日志：

chrome_options.add_argument("--enable-logging")
chrome_options.add_argument("--v=1")
