How To Run Selenium With Chrome In Docker

Question

I installed google-chrome in a Docker, but when I run my Python 2 script of Selenium, it failed like this:

automation@1c17781fef0c:/topology-editor/test$ python          


        

Answer 1

I assume you need to run it in headless mode

https://developers.google.com/web/updates/2017/04/headless-chrome

this is how I do it in ruby

capabilities = Selenium::WebDriver::Remote::Capabilities.chrome(
chromeOptions: {args: %w[ no-sandbox headless disable-gpu window-size=1280,1000 ]})

Capybara::Selenium::Driver.new(app, :browser => :chrome, http_client: client, desired_capabilities: capabilities)

You can pretty much adapt your code in python

also consider installing some font libriaries that chrome needs to run on headless

RUN apt-get update && \
    apt-get -qq -y install  libxpm4 libxrender1 libgtk2.0-0 libnss3\ 
       libgconf-2-4  libpango1.0-0 libxss1 libxtst6 fonts-liberation\ 
       libappindicator1 xdg-utils

RUN apt-get -y install \
               xvfb gtk2-engines-pixbuf \
               xfonts-cyrillic xfonts-100dpi xfonts-75dpi xfonts-base xfonts-scalable \
               imagemagick x11-apps zip
