erb - Comparing two string variables in puppet template -


i'm trying write if statement compares 2 variables in puppet erb template:

<% @array_of_ip_addresses.each_with_index |ip, idx| -%>   <% if @ip == @ipaddress_eth0 -%>     <%= "doing #{idx}" -%>   <% end -%> <% end -%>

i cannot figure out why, condition on if statement keeps returning false (needless confirmed there should match).

what dumb thing missing?

ip block scope variable , not variable instantiated invoking code (in case, puppet's template function), should not specify class instance variable @. when remove , specify block scope variable ip, template like:

<% @array_of_ip_addresses.each_with_index |ip, idx| -%>   <% if ip == @ipaddress_eth0 -%>     <%= "doing #{idx}" -%>   <% end -%> <% end -%>

using class instance variable @ip result in resolution of nil, false nil != @ipaddress_eth0 unless facter failed resolve value eth0 ipaddress, quite uncommon (but still possible).
