The Creating custom facts recipe describes how to add extra facts written in Ruby. You can also create facts from simple text files or scripts with external facts instead.
External facts live in the /etc/facter/facts.d
directory and have a simple key=value
format like this:
message="Hello, world"
Here's what you need to do to prepare your system to add external facts:
You'll need Facter Version 1.7 or higher to use external facts, so look up the value of
facterversion
or usefacter -v
:[root@cookbook ~]# facter facterversion 2.3.0 [root@cookbook ~]# facter -v 2.3.0
You'll also need to create the external facts directory, using the following command:
[root@cookbook ~]# mkdir -p /etc/facter/facts.d
