Capistrano 3 Rails Config
This is a sample configuration for deploying Ruby on Rails applications with Capistrano 3.1 including Zero Downtime Deployment with Unicorn and Sidekiq background Workers.
See http://www.talkingquickly.co.uk/2014/01/deploying-rails-apps-to-a-vps-with-capistrano-v3/ for a tutorial on usage.
Or for more details, this is also the example configuration used in the book Reliably Deploying Rails Applications available on Leanpub: https://leanpub.com/deploying_rails_applications
You should have the following in your Gemfile:
gem 'unicorn', '~> 4.8.3' group :development do gem 'capistrano', '~> 3.2.1' # rails specific capistrano functions gem 'capistrano-rails', '~> 1.1.0' # integrate bundler with capistrano gem 'capistrano-bundler' # if you are using Rbenv gem 'capistrano-rbenv', "~> 2.0" # include helper tasks gem 'capistrano-cookbook', require: false end
