Hi Richie,
There's a few options available with the Ruby ERB templating in Puppet, depending on how you want to control the output, these pages are a good introduction to ERB and Puppet. http://docs.puppetlabs.com/guides/templating.html http://docs.puppetlabs.com/learning/templates.html Here's a few quick examples for you, based on your question. option one: provide an array of all the component numbers required. components = ['1','2','3'] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ <% @components.each { |item| -%> LAUNCH_STRING.Component<%= item %>="Blah" PROCESS_FOOTPRINT.Component<%= item %>-"Blah" <% } -%> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ option two: provide the number of components required components = 4 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ <% (1..@components).each { |item| -%> LAUNCH_STRING.Component<%= item %>="Blah" PROCESS_FOOTPRINT.Component<%= item %>-"Blah" <% } -%> option three: provide an array of component names, the component number is extracted by index position in the array. components = ['blah', 'Blah', 'blaH'] ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ <% @components.to_enum.with_index(1).each { |item, index| -%> LAUNCH_STRING.Component<%= index %>="<%= item %>" PROCESS_FOOTPRINT.Component<%= index %>-"<%= item %>" <% } -%> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Regards Jacob On 4 November 2013 21:31, Richie Rees <richard.ree...@gmail.com> wrote: > Hi, > > Here is my dilemma, have a class that installs an rpm then copies over > the configuration files.
