Getting Started with Merb on Heroku

Install Merb

  • sudo gem update --system
  • sudo gem install merb

Create a Merb Project

  • merb-gen app myproject
  • cd myproject
  • bundle install
    • Requires bundler: sudo gem install bundler
  • thin start -R config.ru
    • Requires thin: sudo gem install thin

Setup Git Repository

  • cd myproject
  • git init
  • git add .
  • git commit -m "Initial commit"

Add Heroku Repository

  • git remote add heroku git@heroku.com:myproject.git

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'
  • SQLite3 for Development
  • Postgres for Production

Deploy to Heroku

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