Overview

Vlad Delivery Method

Vlad is one of the delivery method options available out of the box with Sprinkle. If you have the vlad the deployer gem install, you may use this delivery. The only configuration option available, and which is mandatory to include is script. An example:

deployment do
  delivery :vlad do
    script 'deploy'
  end
end

script is given a list of files which vlad will include and load. These recipes are mainly to set variables such as :user, :password, and to set the app domain which will be sprinkled.
