I'm kind of curious how you came to Docker and PhantomJS being the easiest way, that sounds like the worst possible way to me.

To get things started simply with JS just follow instructions here: http://webdriver.io/guide.html

The only major diversions from that are to use Mocha or Jasmine for your test framework (instructions on the same site) and to automate starting / stopping the selenium server for which there are grunt/gulp plugins.
