Hello,
I''m new to puppet and facter. Initially we are planning on using
facter/puppet to inventory machines (Mac, Ubuntu, and RHEL). We plan
on writing a number of custom facts. Obviouly some of the facts will
only be specific to some OSs. I know there is a "confine" method, but
it confuses me. It seems the confine statement in some of the recipes
and in the Turnbull book is checked after most of the work is done.
Take for example:
if FileTest.exists?("/usr/sbin/dmidecode")
# Add remove things to query here
query = { ''BIOS Information'' =>
''Vendor:'', ''System Information'' =>
[ ''Manufacturer:'', ''Product Name:'' ,
''Serial Number:'', ''Version:'' ],
''Chassis Information'' => ''Type:'',
''Processor Information'' =>
[''Version:'', ''Max Speed:''], ''Memory
Controller Information'' =>
[ ''Maximum Memory Module Size:'', ''Maximum Total
Memory Size:'' ] }
# Run dmidecode only once
output=%x{/usr/sbin/dmidecode 2>/dev/null}
query.each_pair do |key,v|
v.each do |value|
output.split("Handle").each do |line|
if line =~ /#{key}/ and line =~ /#{value} (\w.*)\n*./
result = $1
Facter.add(value.chomp('':'')) do
confine :kernel => :linux
setcode do
result
end
end
end
end
end
end
end
Does this code get executed in the kernel is not Linux, or is the fact
just not added is the kernel is not linux?
Also, should I bundle the facts into one document, say by platform, or
should each fact be in its own file?
Thanks,
Allan Marcus

Never needed to group them together.

If you''re not experiencing load issues, there''s no reason why you have to bundle them together unless you''re sharing code amongst facts. -- Nigel Kersten nigelk@google.com System Administrator Google, Inc. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.

Does the setcode do block get executed if the confine test fails? that would make sense to me, but I just want to be sure.

Looking at Facter 1.5.1''s operatinsystemrelease.rb, there are several stanzas like: Facter.add(:operatingsystemrelease) do confine :operatingsystem => :fedora setcode do File::open("/etc/fedora-release", "r") do |f| line = f.readline.chomp if line =~ /\(Rawhide\)$/ "Rawhide" elsif line =~ /release (\d+)/ $1 end end end end Given that I''d to find a /etc/fedora-release only on Fedora, and I see no other obvious error handling if that file doesn''t exist, I''m going to assume that the confine ensures that the setcode block only runs if the confine passes. -- Mike Renfro / R&D Engineer, Center for Manufacturing Research, 931 372-3601 / Tennessee Technological University -- renfro@tntech.edu --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Puppet Users" group.
