⁠What is PhantomJS

PhantomJS⁠ is a headless WebKit browser, often used via WebDriver⁠ for web system testing. It's based on WebKit, runs JavaScript, and allows to take screenshots.

⁠Features of this image

This Dockerized⁠ version of PhantomJS is:

• Small: Using Debian image⁠ (below 100 MB, while Ubuntu is about 230 MB), and removing packages used during build.
• Simple: Exposes default port, easy to extend.
• Secure: Runs as non-root UID/GID 72379 (selected randomly to avoid mapping to an existing user) and uses dumb-init⁠ to reap zombie processes.

⁠Usage

⁠JavaScript interactive shell

Start PhantomJS in REPL⁠:

$ docker run --rm wernight/phantomjs
>

⁠Remote WebDriver

Start as 'Remote WebDriver mode' (embedded GhostDriver⁠):

$ docker run -d -p 8910:8910 wernight/phantomjs phantomjs --webdriver=8910

To connect to it (some examples per language):

• Java:

  WebDriver driver = new RemoteWebDriver(
      new URL("http://127.0.0.1:8910"),
      DesiredCapabilities.phantomjs());
  

  Copy

• Python (after running $ pip install selenium⁠):

  from selenium import webdriver
  from selenium.webdriver.common.desired_capabilities import DesiredCapabilities
  
  driver = webdriver.Remote(
      command_executor='http://127.0.0.1:8910',
      desired_capabilities=DesiredCapabilities.PHANTOMJS)
  
  driver.get('http://example.com')
  driver.find_element_by_css_selector('a[title="hello"]').click()
  
  driver.quit()
  

  Copy
