在无头Chrome Docker中获取运行硒的空页面 [英] Getting empty page running selenium in headless chrome Docker
问题描述
我正在基于Oracle Linux的Docker中以无头chrome运行测试用例.
我请求的页面应该重定向到带有用户名密码字段的身份验证页面，但是我在docker server()中得到了空白页面.从我的Macbook上可以正常工作.
这是我尝试从docker内部使用chrome浏览器直接运行相同输出时的输出
bash-4.2#google-chrome --headless --no-sandbox --dump-dom --ignore-ssl-errors --ignore-certificate-errors --ssl-protocol = TLSv1 --allow-running-insecure-content --allow-insecure-localhost https://example.com/ [0108/134257.881648:ERROR:bus.cc(393)]无法连接到总线:无法连接到套接字/run/dbus/system_bus_socket:没有这样的文件或目录

即使我在Linux docker上运行，传递的用户代理也是"--user-agent = Mozilla/5.0(Macintosh; Intel Mac OS X 10_15_2)AppleWebKit/537.36(KHTML，like Gecko)Chrome/87.0.4280.88Safari/537.36".我应该使用Linux用户代理吗?
Chrome二进制文件和Chrome网络驱动程序版本:87.0.4280.88这可能是什么原因，我在过去的2天中一直处于这种状态.预先感谢.
Docker文件如下
FROM base_imageARG USER = usr运行yum -y install wget \&&wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm \&&yum -y安装libappindicator-gtk3-12.10.0-13.el7.x86_64 \&&yum -y安装libXScrnSaver-1.2.2-6.1.el7.x86_64 \&&yum -y install liberation-fonts-1.07.2-16.el7.noarch \&&yum -y install liberation-narrow-fonts-1.07.2-16.el7.noarch alsa-lib-1.1.8-1.el7.i686 xdg-utils alsa-lib-devel \&&wget http://mirror.centos.org/centos/7/os/x86_64/Packages/vulkan-filesystem-1.1.97.0-1.el7.noarch.rpm \&&wget http://mirror.centos.org/centos/7/os/x86_64/Packages/vulkan-1.1.97.0-1.el7.x86_64.rpm \&&rpm -ivh vulkan-filesystem-1.1.97.0-1.el7.noarch.rpm \&&rpm -ivh vulkan-1.1.97.0-1.el7.x86_64.rpm \&&rpm -ivh google-chrome-stable_current_x86_64.rpm \&&百胜清理所有运行rm -rf/var/cache/yum;展览8080 因此，肯定是您的docker映像中的问题.安装过程中发生了很多事情，我看不到最明显的是安装实际的 chromedriver .
#安装chromedriver运行apt-get install -yqq解压缩运行wget -O/tmp/chromedriver.zip http://chromedriver.storage.googleapis.com/`curl -sS chromedriver.storage.googleapis.com/LATEST_RELEASE`/chromedriver_linux64.zip运行解压缩/tmp/chromedriver.zip chromedriver -d/usr/local/bin/ 有关自定义docker映像的更多信息，您可以在答案和主题中进行检查.此外，我建议使用预构建的 Selenium docker映像，它对我来说每次都工作得很好./p>
I am running a test cases in headless chrome inside an Oracle Linux based Docker.
The page I request should get redirected to an authentication page with the username password field, but I am getting blank page in the docker server(). This works fine from my macbook.
This is the output when i try do run the same directly using chrome browser from inside docker
bash-4.2# google-chrome --headless --no-sandbox --dump-dom --ignore-ssl-errors --ignore-certificate-errors --ssl-protocol=TLSv1 --allow-running-insecure-content --allow-insecure-localhost https://example.com/

Even though I am running in linux docker, user agent passed is "--user-agent=Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/87.0.4280.88 Safari/537.36". Should I use a Linux user agent?
Chrome binary and Chrome webdriver version : 87.0.4280.88 What could be the reason for this, I am stuck in this for last 2 days. Thanks in Advance.
Docker file is as below
FROM base_image
ARG USER=usr
RUN yum -y install wget \
&& wget https://dl.google.com/linux/direct/google-chrome-stable_current_x86_64.rpm \
&& yum -y install libappindicator-gtk3-12.10.0-13.el7.x86_64 \

&& yum clean all
RUN rm -rf /var/cache/yum;
EXPOSE 8080
So the problem in your docker image for sure. There are many thing happening in install and I don't see most obvious one with install of actual chromedriver.
# install chromedriver
RUN apt-get install -yqq unzip
RUN wget -O /tmp/chromedriver.zip http://chromedriver.storage.googleapis.com/`curl -sS chromedriver.storage.googleapis.com/LATEST_RELEASE`/chromedriver_linux64.zip
RUN unzip /tmp/chromedriver.zip chromedriver -d /usr/local/bin/
More information about custom docker image you can check in this answer and thread. Furthermore I would suggest to go with prebuilt Selenium docker image which works perfectly every time for me.
