Step one: create an array of the desired resource titles, of some other
suitable identifiers of the target resource, or of something you can
transform into the same. To do this without writing a custom function, you
probably need to create a list of the titles in string form via
inline_template(), then split() it.
Step two: use the array of titles to declare the desired resources.
Details depend on your exact needs: maybe you can just declare packages,
but you can also declare instances of a defined type.
That might come together something like this:
class site::kernel_dirvers {
$kernel_fact_stem = 'installed_kernel'
$kernel_list = inline_template("<%=
(0...@installed_kernel_count.to_i).collect{|n| @kernel_fact_stem +
n.to_s}.join(',') %>")
$kernels = split($kernel_list, ',')
site::my_kernel_driver { $kernels: }
}
define site::my_kernel_driver () {
$driver_title = "mykod-${title}"
# ensure the selected driver present,
# maybe something like this:
package { $driver_title: ensure => latest }
}
