# This is a skeleton for testing models including examples of validations, callbacks,
# scopes, instance & class methods, associations, and more.
# Pick and choose what you want, as all models don't NEED to be tested at this depth.
#
# I'm always eager to hear new tips & suggestions as I'm still new to testing,
# so if you have any, please share!

Zero downtime deploys with unicorn + nginx + runit + rvm + chef

Below are the actual files we use in one of our latest production applications at Agora Games to achieve zero downtime deploys with unicorn. You've probably already read the GitHub blog post on Unicorn and would like to try zero downtime deploys for your application. I hope these files and notes help. I am happy to update these files or these notes if there are comments/questions. YMMV (of course).

Other application notes:

  • Our application uses MongoDB, so we don't have database migrations to worry about as with MySQL or postgresql. That does not mean that we won't have to worry about issues with the database with indexes being built in MongoDB or what have you.
  • We use capistrano for deployment.

Salient points for each file:

# encoding: UTF-8
Capistrano::Configuration.instance(:must_exist).load do
namespace :rails do
desc "Open the rails console on one of the remote servers"
task :console, :roles => :app do
hostname = find_servers_for_task(current_task).first
exec "ssh -l #{user} #{hostname} -t 'source ~/.profile && #{current_path}/script/rails c #{rails_env}'"
end
