Docker+Google Cloud+chromedriver->可执行文件需要在路径中

dockerfile selenium-chromedriver google-cloud-platform docker python

Aurimas Deimantas · 技术社区 · 5 年前

我已经花了两天时间,头发都掉光了。我在谷歌云计算机上运行ubuntu。我的Dockerfile看起来像这样


# Project files
ARG PROJECT_DIR=/srv/api
RUN mkdir -p $PROJECT_DIR
WORKDIR $PROJECT_DIR

# Install Python dependencies
COPY ./ ./
RUN mv /srv/api/app/chromedriver_linux /usr/bin/chromedriver_linux
RUN ls /usr/bin/

我写ls来检查我的路径中是否存在chromedriver_linux。它确实存在于 /usr/bin/chromedriver_linux

然后在我的代码中指定

chrome_options = webdriver.ChromeOptions()
    chrome_options.add_argument('--disable_infobars')
    chrome_options.add_experimental_option("mobileEmulation", mobile_emulation)
    driver = webdriver.Chrome('/usr/bin/chromedriver_linux', options=chrome_options)

我收到

selenium.common.exceptions.WebDriverException: Message: 'chromedriver_linux' executable needs to be in PATH. Please see https://sites.google.com/a/chromium.org/chromedriver/home

有趣的是,如果我在本地机器上运行Docker并为mac指定chromedriver,它就可以工作了。我不明白为什么它可以在本地机器上运行,但不能在云上运行。

期待着听到你们,聪明人,我错过了什么!

经过几天不睡觉,我终于明白了。

首先,我运行的是阿尔卑斯版的Ubuntu。这是第一个问题。但我成功了。所以,如果你们也在运行Alpine,这就是解决方案:

Dockerfile

FROM python:3.6.6-alpine3.8

# Project files
ARG PROJECT_DIR=/srv
RUN mkdir -p $PROJECT_DIR
WORKDIR $PROJECT_DIR

# Install Python dependencies
COPY ./ ./

RUN apk update
RUN apk add curl
RUN apk add unzip nano bash chromium chromium-chromedriver

RUN pip3 install -r requirements.txt

整个魔法就是安装铬。现在是我们的*。py看起来像这样:

mobile_emulation = {"deviceName": "iPhone X"}
    chrome_options = webdriver.ChromeOptions()
    chrome_options.add_argument('--headless')
    chrome_options.add_argument('--no-sandbox')
    chrome_options.add_argument('--disable-dev-shm-usage')

    #chrome_options.add_argument('--disable_infobars')
    chrome_options.add_experimental_option("mobileEmulation", mobile_emulation)
    driver = webdriver.Chrome(executable_path='/usr/bin/chromedriver', options=chrome_options)
    driver.get('https://google.com')

奖金 . 我想用不同的 chromedriver 决定阿尔卑斯山真的把事情搞砸了。用python安装了合适的ubuntu并使chromedriver正常工作。下面是它的外观: Dockerfile

FROM ubuntu:18.04

# Project files
ARG PROJECT_DIR=/srv
RUN mkdir -p $PROJECT_DIR
WORKDIR $PROJECT_DIR


# Update
RUN apt-get update
RUN apt-get -y upgrade


# Set the locale
RUN apt-get install -y locales && locale-gen "en_US.UTF-8" && dpkg-reconfigure -f noninteractive locales
ENV LANG en_US.UTF-8
ENV LANGUAGE en_US:en
ENV LC_ALL en_US.UTF-8
ENV PYTHONIOENCODING utf-8

RUN echo \
    && echo 'LANG=en_US.UTF-8' >> /etc/environment \
    && echo 'LANGUAGE=en_US:en' >> /etc/environment \
    && echo 'LC_ALL=en_US.UTF-8' >> /etc/environment \
    && echo 'PYTHONIOENCODING=utf-8' >> /etc/environment


# Install Python dependencies
RUN apt-get install --upgrade -y python3-pip
RUN apt-get install -y build-essential libssl-dev libffi-dev python3-dev
RUN apt-get install -y curl
RUN apt-get install -y unzip


# Copy everything to Docker
COPY ./ ./

# Install chromium instead
RUN apt-get install -y chromium-browser

# Install chromedriver for Chromium
RUN curl https://chromedriver.storage.googleapis.com/75.0.3770.140/chromedriver_linux64.zip -o /usr/local/bin/chromedriver.zip
RUN unzip /usr/local/bin/chromedriver.zip -d /usr/local/bin/
RUN chmod +x /usr/local/bin/chromedriver || rm /usr/local/bin/chromedriver.zip

RUN pip3 install -r requirements.txt

我们的代码如下所示:

 mobile_emulation = {"deviceName": "iPhone X"}
    chrome_options = webdriver.ChromeOptions()
    chrome_options.add_argument('--headless')
    chrome_options.add_argument('--no-sandbox')
    chrome_options.add_argument('--disable-dev-shm-usage')

    #chrome_options.add_argument('--disable_infobars')
    chrome_options.add_experimental_option("mobileEmulation", mobile_emulation)
    driver = webdriver.Chrome(executable_path='/usr/local/bin/chromedriver', options=chrome_options)
    driver.get('https://google.com')
    driver.close()
