I''m trying to write a custom fact for Puppet, but I have next to no Ruby experience. I think what I''m trying to do is straightforward, but because of Facter''s key => value pairs model, it''s kind of difficult. Each hosts I want the fact for has websites in /var/www/html/ - I want to be able to do the following: Have a fact called "websites" that will tell me how many folders there are under /var/www/html Have a list of facts called website_1, website_2, website_3 which will tell me the names of these sites. Either that or have an array (if that''s even possible) called website_names which will then list all the websites under that key. If possible, I''d like the fact to be able to figure out how many websites there are with the original "websites" fact and limit the number of websites underneath. Any help gratefully appreciated. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.

I think you might be using the wrong tool for the job, but we need a little bit more information to determine that: What do you want to do with these facts once you have them in puppet? If you are managing websites with puppet, you should probably manage the folders themselves with puppet, removing your need for the fact. cheers, Walter On Sun, Nov 25, 2012 at 10:16 PM, frap <lee@brig.gs> wrote:> I''m trying to write a custom fact for Puppet, but I have next to no Ruby > experience.

Then you might not need to list them out. Either way, you can comma separate strings and use things like split in Puppet (and maybe stdlib) to do some things. I used dozens of custom facts in my environment in the past, so I can''t tell you if this is *wrong* way per say. It''s a way. Go for it until you find something better. Also note, if you''re not really into writing ruby facts, you could use something in facts.d that is provided via stdlib. That just reads values from files. You could write your fact in whatever language you want, run it in cron or something and then have it dump results from /etc/facter/facts.d or /etc/puppetlabs/facter/facts.d. stdlib: http://forge.puppetlabs.com/puppetlabs/stdlib>> >> Each hosts I want the fact for has websites in /var/www/html/ - I want to be >> able to do the following: >> >> Have a fact called "websites" that will tell me how many folders there are >> under /var/www/html >> >> Have a list of facts called website_1, website_2, website_3 which will tell >> me the names of these sites.

Answering the requirement you could do something like.
Facter.add("websites_number") do
setcode do
websites = %x{/bin/ls $websitesdir}.split("\n")
0.upto(websites - 1).each do |n|
Facter.add("website_#{n}") do
setcode do
websites[n]
end
end
websites.size
end
end
