We'll build our own custom DB type for this simple use case. It will allow us to pass values from our database to our WordPress application. This simple example ensures that the type is named db, marks it as a service resource, and provides five available parameters to the database service resource. This file is placed in lib/puppet/type/db.rb:

# lib/puppet/type/db.rb
# Adding :is_capability to the custom type marks the resources as service resources
Puppet::Type.newtype :db, :is_capability => true do
  newparam :name, :is_namevar => true
  newparam :user
  newparam :password
  newparam :port
  newparam :host
end
