RE: [Puppet Users] puppet facter variable substring

[Steven Nemetz]

You can use regex for that
 
Here is an piece of my code for doing that. In my case [environment, 1 letter][collo, 2 letters]
 
  if $hostname =~ /^(.)(..)/ {
    $global_env = $1
    $location = $2
  }

Subject: [Puppet Users] puppet facter variable substring

Hi 

I have a serires of servers that their hostname (not FQDN) is built in the same manner [header, 3 letters][collo, 4 letters][environment, 3 letters][number, 4 digits]. 

There's no specific separator between each part of hostname. Is there way I can extract the collo part of the hostname in puppet? 

TIA 

Paolo

Hi Steven 

Why the if statement? 

TIA

Not sure if puppet will let you access regex without being in some type of test.
Also, just habit. I'm usually doing some validation in the regex.

In this case, I've moved validation to after this and have it validate against data in hiera. Hiera has a list of the valid data center codes.
