I am customizing an existing puppet installation (with facter) and I think I ran into an issue understanding the scope of custom facts.
I have several modules that are mapped exclusively to different classes of hosts within a nodes.pp file.
What I'd like to achieve would be to have custom facts limited by module, for example hosts in
module1 would execute
custom_fact_1 and hosts in
module2 would only execute
According to the facter/puppet docs, the custom facts go into a
<module-name>/lib/facter directory, and are tied to that module.
I have made it gather a few custom facts already, by adding the ruby scripts to a single module's
lib/facter dir, but strangely they are not limiting themselves to the hosts to which the module is assigned. What is happening is that all custom facts are ran for all hosts (even the ones that don't have any relationship to that module), which is not exactly what I intended.
Did I misunderstand the documentation? Is this type of fact-module mapping possible?
Note: I have achieved a similar behaviour by using
confine instructions in the custom facts scripts, but this goes against the intended purpose, since I'd like to tie the custom facts to the modules themselves and not have the mapping in the scripts.
