+Earlier versions of Ruby are used in production because upgrading presents challenges such as, critical gems are not backward-compatible. Debugging tools like pry, rubocop, byebug... do work on many versions, but not consistently on all Ruby versions.
 
 As a result, Ruby developers (and people deploying Ruby apps) rely on tools like [rvm](https://rvm.io/) or [rbenv](https://github.com/rbenv/rbenv) to install a specific version of Ruby. These tools enable developers to switch between different versions of Ruby, and between different sets of gems (when different applications have conflicting requirements).

 In this section we will deploy the [Docker Pets](https://github.com/mark-church/docker-paas) application using a compose file. In the following sections we will add features to our compose file and make our application progressively more complex and feature-full. Docker Pets is a simple web app that records votes for different animals and uses a persistent backend to record the votes. It's comprised of two images:
