Setting up and installing rbenv, ruby-build, rubies, rbenv-gemset, and bundler

This guide enables you to install (ruby-build) and use (rbenv) multiple versions of ruby, isolate project gems (gemsets and/or bundler), and automatically use appropriate combinations of rubies and gems.

TL;DR Demo

# Ensure system is in ship-shape.

aptitude install git zsh libssl-dev zlib1g-dev libreadline-dev libyaml-dev

Recently, I had a staging database on Heroku that was running on the Ronin database (which was originally the lowest-sized DB you could get at Heroku). Since they added two new options, Crane and Kappa, we wanted to take advantage of the cost savings. Here's how you can migrate your Ronin DB to Crane (or any other plan).

The old database was named BROWN while the new one is CRIMSON. You can determine this by running:

heroku pg:info --app myapp-staging

1. Add Crane database

    heroku addons:add heroku-postgresql:crane --app myapp-staging
   

heroku pg:wait --app myapp-staging
