Trying to write a custom facter module:
Facter.add("something_status") do
setcode do
$string_to_parse = Facter::Util::Resolution.exec('somecommand --print ')
... do something to string
return something-new
end
end
Very new to ruby... what would be the proper syntax to do something with this?
You are not far away from doing it.. you dont need $ before variable names and you should not end with return. Latest var on scope will be retrieved by Facter.
Below it's an example code that analyze uname output and returns a fact with a string about kernel version and ipv6 support of it.
It's just an example but it works, just tried it.
Facter.add("customer") do
setcode do
kernel_release = Facter::Util::Resolution.exec('/bin/uname -r')
# Get version
if kernel_release =~ /^3.2/
answer = "Latest Kernel"
elsif kernel_release =~ /^3.0/
answer = "3.0 Kernel"
elsif kernel_release =~ /^2.6/
answer = "Decent Kernel"
else
answer = "Unknown Kernel"
end
if answer =~ /ipv6/
answer += " with IPV6 Support"
else
answer += " without IPV6 Support"
end
end
end
Good Luck!
