A Capistrano deployment recipe that works for my Ubuntu, Apache, Passenger, RVM, Bundler, Ruby on Rails setup (Linode). It's based on this gist https://gist.github.com/meskyanichi/157958. I just added RVM and Bundler support and remove a bunch of stuff I'm not currently using.

deploy.rb

# =================================== #
# RVM/CAPISTRANO/BUNDLER SETUP        #
# =================================== #

set :rvm_ruby_string, :local # use the same ruby as used locally for deployment
set :rvm_autolibs_flag, "install-packages" # more info: rvm help autolibs
set :rvm_install_with_sudo, true #:use_sudo is set to 'false' but sudo is needed to install requirements with autolibs
before 'deploy:setup', 'rvm:install_ruby'  # install Ruby and create gemset

require "rvm/capistrano"
require 'bundler/capistrano'
