Rails Rumble 2013 - Official Linode StackScript - Capistrano Deployment Recipe

deploy.rb

require 'bundler/capistrano'

# This capistrano deployment recipe is made to work with the optional
# StackScript provided to all Rails Rumble teams in their Linode dashboard.
#
# After setting up your Linode with the provided StackScript, configuring
# your Rails app to use your GitHub repository, and copying your deploy
# key from your server's ~/.ssh/github-deploy-key.pub to your GitHub
# repository's Admin / Deploy Keys section, you can configure your Rails
# app to use this deployment recipe by doing the following:
#
# 1. Add `gem 'capistrano', '~> 2.15'` to your Gemfile.
# 2. Run `bundle install --binstubs --path=vendor/bundles`.
# 3. Run `bin/capify .` in your app's root directory.
# 4. Replace your new config/deploy.rb with this file's contents.
# 5. Configure the two parameters in the Configuration section below.
# 6. Run `git commit -a -m "Configured capistrano deployments."`.
# 7. Run `git push origin master`.
# 8. Run `bin/cap deploy:setup`.
# 9. Run `bin/cap deploy:migrations` or `bin/cap deploy`.
#
# Note: You may also need to add your local system's public key to
# your GitHub repository's Admin / Deploy Keys area.
#
# Note: When deploying, you'll be asked to enter your server's root
# password. To configure password-less deployments, see below.
