Docker + Google Cloud + chromedriver -> 可执行文件需要在 PATH 中

Aur*_*tas 2 python selenium-chromedriver docker google-cloud-platform dockerfile

我已经度过了最后两天,我正在失去我的头发。我在我的 Google Cloud 机器上运行 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 chromedriver_linux 是否存在于我的路径中。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 - 它可以工作。我无法弄清楚 - 为什么它可以在本地机器上运行但不能在云上运行。

期待听到你的声音,聪明的人,我在这里错过了什么!

终于在几个非睡眠日之后我得到了它。

首先,我运行的是 Ubuntu 的 Alpine 版本。这是第一个问题。但我让它工作了。所以如果你们也在运行 Alpine,这是解决方案:

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

整个魔术就是安装 Chromium。现在我们的 *.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。我想使用不同的,chromedriver并决定 Alpine 真的把事情搞砸了。使用 python 安装了适当的 ubuntu 并使 chromedriver 工作。这是它的外观: Dockerfile

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()
