Recipe to run on deployment and standalone - amazon-web-services

Question

I have a recipe below (migrate.rb) which is run as part of our deployment and works perfectly.
However one thing that I can't workout is how to set it up so it can also be run as a standalone recipe in the execute_recipe command.
As it stands if we execute this recipe as a stand alone then nothing happens since the node[:deploy].each has nothing to loop over (the deploy key doesn't exist)..
The only part that actually relies on the deploy node is this line cwd "#{deploy[:deploy_to]}/current" since I need to know where the code was deployed to.
node[:deploy].each do |application, deploy|
execute 'DB migrate then seed' do
cwd "#{deploy[:deploy_to]}/current"
command 'php artisan migrate; while read -r line || [ -n "$line" ]; do php artisan db:seed --class="$line"; done < "app/database/run.list"'
end
end

I would relocate that part to a definition (or a provider). So basically split your recipe in two parts:
recipes/deploy.rb:
node[:deploy].each do |application, deploy|
php_artisan_setup do
dir "#{deploy[:deploy_to]}/current"
end
end
definitions/php_artisan_setup.rb:
define :php_artisan_setup do
execute 'DB migrate then seed' do
cwd params[:dir]
command 'php artisan migrate; while read -r line || [ -n "$line" ]; do php artisan db:seed --class="$line"; done < "app/database/run.list"'
end
end
This way, you can call php_artisan_setup from your "standalone" recipe, too. You still need two recipes, but you dont have to duplicate the relevant part.
