在 docker-compose 中运行 Selenium：未创建会话：DevToolsActivePort 文件不存在

问题描述 投票：0回答：1

我想在我的 

Ubuntu 服务器
上的 docker-compose 中运行 Selenium。

我有

Dockerfile

FROM python:3.13.1-slim-bookworm

ENV POETRY_VERSION=2.0.1
ENV PYTHONUNBUFFERED=1
ENV POETRY_VIRTUALENVS_CREATE=false
ENV USER=ma

SHELL ["/bin/bash", "-o", "pipefail", "-c"]

RUN groupadd -r $USER && useradd -r -g $USER -d /opt/$USER $USER

RUN apt-get update \
  && apt-get install -y --no-install-recommends \
  wget \
  unzip \
  gnupg \
  libglib2.0-0 \
  libnss3 \
  libgconf-2-4 \
  libfontconfig1 \
  libxcb1 \
  && wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add - \
  && sh -c 'echo "deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google-chrome.list' \
  && apt-get -y update \
  && apt-get install -y google-chrome-stable \
  && apt-get clean \
  && rm -rf /var/lib/apt/lists/*

# Install poetry
RUN pip install --no-cache-dir --upgrade pip \
    && pip install --no-cache-dir poetry==${POETRY_VERSION}

WORKDIR /opt/$USER
RUN mkdir -p /opt/$USER/.cache/selenium && chown -R $USER:$USER /opt/$USER/.cache

COPY ./poetry.lock ./pyproject.toml ./
RUN poetry install --no-interaction --no-cache --no-root

COPY ignore_list.txt ./
COPY app app

USER $USER

ENTRYPOINT ["poetry", "run", "python", "-m", "app.get_next_predictions"]


docker-compose.yaml

services:
  app:
    image: portal
    container_name: portal
    build:
      context: .
      dockerfile: deployments/Dockerfile
    env_file:
      - .env

和运行代码 

webdriver

def start_browser(portal_config: PortalSettings) -> webdriver.Chrome:
    options = Options()
    options.add_experimental_option("useAutomationExtension", False)
    options.add_experimental_option("excludeSwitches", ["enable-automation"])
    options.add_experimental_option("detach", True)
    options.add_argument("--disable-dev-shm-usage")
    options.add_argument("--disable-extensions")  # Disable browser extensions
    options.add_argument("--disable-crash-reporter")  # Disable crash reporting
    options.add_argument("--disable-infobars")  # Disable infobars
    options.add_argument("--disable-logging")
    options.add_argument("--disable-background-timer-throttling")
    options.add_argument("--disable-backgrounding-occluded-windows")
    options.add_argument("--disable-renderer-backgrounding")
    options.add_argument("--no-sandbox")
    options.add_argument("--headless")
    options.add_argument("--disable-gpu")
    options.add_argument("--start-maximized")
    options.add_argument('log-level=3')
    options.add_experimental_option('excludeSwitches', ['enable-logging'])
    browser = webdriver.Chrome(options=options)
    browser.maximize_window()
    browser.get('https://www.portal.com/login')
    login(browser, portal_config)
    return browser

当我启动应用程序时，出现错误

此外，当我在本地 MacOS (M1) 上运行此代码时，它工作正常。

更新：当我删除创建的用户时它就可以工作......为什么？以及如何修复它并与非 root 用户一起工作。

python docker ubuntu selenium-webdriver

需要修复目录的权限

RUN mkdir -p /dev/shm \
  && chmod 1777 /dev/shm \
  && mkdir -p /tmp \
  && chmod -R 777 /tmp \
  && mkdir -p /opt/$USER \
  && chown -R $USER:$USER /opt/$USER

最终
