Facter displaying multiple IP addresses?

[Will S. G.]

Hi,

I have a motd module (not mine) that rewrites /etc/motd with some
useful host details. One particular piece of information is the IP
address in motd.erb:

FQDN: <%= fqdn %>
IP: <%= ipaddress %>

I have several hosts that have multiple IP addresses, and I need to
display them as well. When I run facter | grep ipaddress, I get an
array:

ipaddress => 172.26.20.16
ipaddress_eth0 => 172.26.20.16
ipaddress_eth1 => 10.20.30.5
ipaddress_eth2 => 10.20.40.5
ipaddress_eth3 => 10.20.50.5
ipaddress_eth4 => 10.20.60.5
ipaddress_eth5 => 10.20.70.5

Is there a way to display eth{0-5} as well?

You could do a for loop from 0 to N (5?) and check if the variable exists (if has_variable?("ipaddress_eth" + index)) then print it. I'm sure there's probably a nicer way of doing this in Ruby :)

You could do

IP: <%= scope.to_hash.inject([]) { |acc, (k,v)| acc << v if k =~ /^ipaddress_/; acc }.join(', ') %>
