Docker Selenium:selenium.common.exceptions.WebDriverException:消息:服务chromedriver意外退出.状态码为:127

问题描述

我在python项目中使用了硒的chromedriver.

I am using selenium's chromedriver in my python project.

我正在成功构建我的Dockerfile:

I am building successfully my Dockerfile:

FROM ubuntu:17.04
FROM selenium/standalone-chrome
FROM python:3.6
RUN apt update
RUN apt-get install -y libnss3 libgconf-2-4
ADD ./requirements.txt /tmp/requirements.txt
RUN python -m pip install -r /tmp/requirements.txt
ADD . /opt/example1/
# rights?
RUN chmod +x /opt/example1/assets/chromedriver
WORKDIR /opt/example1
CMD ["python","-u","program.py"]

但是当我运行docker容器时，出现以下错误:

But when I run my docker container I got following error:

任何人都知道我该怎么做才能防止此错误?是什么原因导致此崩溃?

Anyone got an idea what could I do to prevent this error?What is causing this crash?

这是我的发生错误的初始化代码:

Here is my initialization code where error occurs:

CHROME_DRIVER_PATH = os.path.abspath('assets/chromedriver')


class MdCrawler(Crawler):

def __init__(self, start_url, source):
    super().__init__(start_url, source)
    serialized_arr = self.read_data_from_json_file(JSON_FILE_PATH)
    self.sent_ids = [] if serialized_arr is None else serialized_arr
    >>> self.web_driver_chrome = webdriver.Chrome(executable_path=CHROME_DRIVER_PATH)
    exit(1)

我已经编辑了Dockerfile(添加了ubuntu:17.04和aptget libnss3 libgconf-2-4).构建了我的docker镜像后，出现了另一个错误:

I have edited Dockerfile (added ubuntu:17.04 and aptget libnss3 libgconf-2-4). After building my docker image, I got different error:

我已添加

RUN wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -
RUN echo 'deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main' | tee /etc/apt/sources.list.d/google-chrome.list
RUN apt-get update
RUN apt-get install -y google-chrome-stable

对于我的Dockerfile，但是新错误即将出现:

To my Dockerfile, but new error is coming:

推荐答案

我在Docker容器中的Selenium chromedriver最小测试脚本如下:

My minimal test script for Selenium chromedriver inside my Docker container looks like this:

import selenium.webdriver

options = selenium.webdriver.ChromeOptions()
options.add_argument('--headless')
options.add_argument('--no-sandbox')

driver = selenium.webdriver.Chrome(chrome_options=options)
driver.get('https://www.python.org/')
print(driver.title)
driver.close()

因此，您好像缺少了--headless和--no-sandbox自变量.

So it looks like you're missing --headless and --no-sandbox arguments.
