I have run the code by hand and it works just fine. Here it is:
#################
require 'facter'
def addFact(name , cmd)
matches = cmd.scan(/\$\{\w+\}/)
if ! matches.empty?
for i in 0...matches.length
match = matches[i]
match = match[2..-2]
value = Facter[match].value()
if value == nil
value = ''
end
cmd = cmd.gsub(/\$\{#{Regexp.escape(match)}\}/, value)
end
end
Facter.add(name) do
setcode do
`#{cmd}`.chomp
end
end
end
#
# List of facts to define,
#
# Can have references to previous facts by using the ${var} syntax
#
facts = {
'ec2_region' => 'cat /opt/aws/info/region',
'ec2_instance_id' => 'cat /opt/aws/info/instance-id',
'ec2_url' => 'echo "https://ec2.${ec2_region}.amazonaws.com";',
'ec2_zone' => "ec2-metadata -z | awk {'print $NF'}"
}
if ! Facter['ec2_ami_id']
puts "Not loading aws_facts"
else
keys = facts.keys
for key in 0...keys.length
fact = keys[key]
addFact(fact, facts[fact])
end
end
##############
Its a simple script that sets up some facts about aws ec2 instances.
Hope this helps.
