Webdriver 无法在 Docker 容器中工作

Question

我正在尝试在 Google Cloudrun 上部署我的抓取工具，但是出现以下错误。

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to 

start: exited abnormally.

我假设这将是版本不匹配，但由于我的 docker 文件正在下载最新的稳定版本85.0.4183.83，即使在将其与chromedriver-binary==85.0.4183.83.0 错误不断发生之后，我也尝试了最新版本的 chromdriver-binary，但85.0.4183.87.0结果是相同。

Docker 文件：

# Use the official lightweight Python image.

# https://hub.docker.com/_/python

FROM python:3.8-slim

# Install manually all the missing libraries

RUN apt-get update

RUN apt-get install -y gconf-service wget libasound2 libgbm1 libappindicator3-1 libatk1.0-0 libcairo2 libcups2 libfontconfig1 libgdk-pixbuf2.0-0 libgtk-3-0 libnspr4 libpango-1.0-0 libxss1 fonts-liberation libappindicator1 libnss3 lsb-release xdg-utils

安装过程中没有问题，只有运行过程中出现问题。任何帮助深表感谢。

您是否以 root 身份运行驱动程序？如果是这样，请尝试使用该--no-sandbox选项作为驱动程序的第一个参数。尽管由于存在漏洞，我建议不要以 root 身份运行它。我从您的评论中看到，这解决了问题，但如果安全性对您的情况确实很重要，我建议您创建一个非 root 用户来运行您的服务。
