Unicorn family Rack handlers for you. Mostly for rails s.

• Rack
• The web server you want to use (e.g. unicorn, yahns, rainbows, zbatery, etc)

gem install rack-handlers

For rails s, put this into your Gemfile:

group :development do
  gem 'rack-handlers', :require => 'rack/handler/rails-server'
end

gem 'unicorn'

And don't forget your favourite unicorns, then you could do the following:

rails s # a sensible default
rails s unicorn
rails s yahns
rails s rainbows
rails s zbatery

Because requiring 'rack-handlers' would make Rack::Handler.default pick the server with the following order:

• yahns
• zbatery
• rainbows
• unicorn
• torquebox (for jruby)
• trinidad (for jruby)
• puma
• thin
• webrick

Thus if you have rainbows installed, rails s would launch the server with rainbows instead of webrick (the original behaviour).

Additionally, it would also try to load the config via config/yahns.rb, or config/unicorn.rb depending on which server is picked.

For people who likes to run rails s!

Then you could use the newly added option -C, or --CONFIG:

rails s -C config/twilight.rb
rails s --CONFIG config/rarity.rb

So that it would overwrite the default config path.
