Note: This fork makes some minimal changes to make this awesome gem work with Rainbows. License and authors were maintained.

The README file was altered to match the renamed capistrano tasks.

This is a capistrano v3 plugin that integrates Rainbows tasks into capistrano deployment scripts; it was heavily inspired by sosedoff/capistrano-unicorn but written from scratch to use the capistrano 3 syntax.

• The rainbows:start task invokes Rainbows as bundle exec rainbows.

• When running tasks not during a full deployment, you may need to run the rvm:hook:

  cap production rvm:hook rainbows:start

You can override the defaults by set :rainbows_example, value in the config/deploy.rb or config/deploy/ENVIRONMENT.rb capistrano deployment files.

Example Unicorn config examples/unicorn.rb

• :rainbows_pid

  Default assumes your pid file will be located in CURRENT_PATH/tmp/pids/rainbows.pid. The rainbows_pid should be defined with an absolute path.

• :rainbows_config_path

  Default assumes that your rainbows configuration will be located in CURRENT_PATH/config/rainbows/RAILS_ENV.rb

• :rainbows_roles

  Roles to run rainbows commands on. Defaults to :app

• :rainbows_options

  Set any additional options to be passed to rainbows on startup. Defaults to none

• :rainbows_rack_env

  Set the RACK_ENV. Defaults to deployment unless the RAILS_ENV is development. Valid options are "development", "deployment", or "none". See the RACK ENVIRONMENT section of the rainbows documentation for more information.

• :rainbows_bundle_gemfile

  REMOVED in v0.2.0

  Set the BUNDLE_GEMFILE in a before_exec block in your unicorn.rb. See sandbox and unicorn-restart-issue-with-capistrano

• :unicorn_restart_sleep_time

  In rainbows:legacy_restart send the USR2 signal, sleep for this many seconds (defaults to 3), then send the QUIT signal

Add the library to your Gemfile:

group :development do
  gem 'capistrano3-rainbows'
end

Add the library to your Capfile:

require 'capistrano3/unicorn'

Invoke Rainbows from your config/deploy.rb or config/deploy/ENVIRONMENT.rb:

If preload_app:true use:

after 'deploy:publishing', 'deploy:restart'
namespace :deploy do
  task :restart do
    invoke 'rainbows:restart'
  end
end

If preload_app:true and you need capistrano to cleanup your oldbin pid use:

after 'deploy:publishing', 'deploy:restart'
namespace :deploy do
  task :restart do
    invoke 'rainbows:legacy_restart'
  end
end

Otherwise use:

after 'deploy:publishing', 'deploy:restart'
namespace :deploy do
  task :restart do
    invoke 'rainbows:reload'
  end
end

Note that presently you must put the invoke outside any on block since the task handles this for you; otherwise you will get an undefined method 'verbosity' error.
