Capistrano::Unicorn

Unicorn basic tasks for Capistrano v3:

• cap unicorn:restart
• cap unicorn:stop

There is no start task since Capistrano v3 only use restart. The unicorn:restart will handle both the start and the restart of the unicorn server.

Some unicorn specific options

set :unicorn_rails_env, ->{ fetch :rails_env, "production" }
set :unicorn_pid_path, ->{ File.join(current_path, 'tmp', 'pids', 'unicorn.pid') }
set :unicorn_config_path, ->{ File.join(current_path, 'config', 'unicorn.rb') }

The task will use the unicorn_rails binary to avoid unnecessary middlewares added by the unicorn binary (Rails already takes care of that)

Add this line to your application's Gemfile:

gem 'capistrano-unicorn-rails'

Require capistrano/unicorn inside your Capfile to load all tasks.

By default, no task are automatically added since Capistrano will remove the default deploy:restart in its version 3.1. You'll need to invoke directly the task inside your config/deploy.rb

namespace :deploy do
  desc 'Restart application'
  task :restart do
    invoke 'unicorn:restart'
  end
end

or

after 'deploy:published', 'unicorn:restart'
