I guess one way would be to write a small custom function which gets an
array as an argument and returns an array of sources.
(didnt test :))
module Puppet::Parser::Functions
newfunction(:array2source, :type => :rvalue) do |args|
if args[0].is_a?(Array)
sources = Array.new
args[0].each {|s| source << "puppet://server/module/configfile.#{s}"}
end
sources << "puppet://server/module/configfile.default"
return sources
end
end
and then in your manifest just do:
file { "/etc/somefile.conf":
source => array2source(clusters)
}
cheers,
Ohad
