Update Heroku Stack to use Bamboo (Beta)

This is required because bundler is the gem manager. Currently, the Bamboo stack is in beta. Heroku provides a nice article on bundler.

• View stack options: heroku stack
• Activate the stack: heroku stack:migrate bamboo-ree-1.8.7

Prepare Gemfile for Heroku Bamboo Stack

The Heroku Bamboo stack does have preinstalled gems, so all gems must be declared in the Gemfile. Merb generates a default Gemfile that covers most of the gems. However, Heroku requires a few extras.

• Gem Source: source :gemcutter
• Bundler: gem 'bundler', '0.9.20'
  • Bundler is a tricky one. Each Bamboo stack uses a different bundler version. See the heroku bundler article for details.
• SQLite3 for Development
• Postgres for Production

Deploy to Heroku

• git push heroku master
• Open browser to: http://myproject.heroku.com/
