Hi Nir,
You want to collect information on nodes and you want to use this information
in a catalog.
This is what facter is used for.
<module>/lib/facter/upgradable_packages.rb
Facter.add(:upgradable_packages) do
setcode do
Facter::Core::Execution.execute("/usr/bin/apt --simulate upgrade | grep
'^Inst' | awk -F ' ' '{print $2}'")
end
end
Within your puppet code you can then refer to the fact:
notify { $upgradable_packages: }
Hth,
Martin
