Hello Docker World!

This is a bare bones, dockerized Sinatra web app I like to use for demos, trainings, and testing.

In particular, I use this image in these projects:

• A dockerized Selenium grid using RSpec + Capybara
• A dockerized Selenium grid using Nightwatch
• A dockerized Selenium grid using Watir
• A slim and simple wait-for docker container utility

You're welcome to use it too.

How'd you make this?
