Puppet users - Apr 2011 - Fetching the domain name from a string variable

Hi guys,

is there a simple way to fetch the domain name (e.g. test-domain.tld) from
a string variable (e.g. host-internal.test-domain.tld)?

Directly use the domain fact from facter or:

I should have been more clear about what I''m trying to achieve.
I''m not
talking about the domain name of a node but from a string contained
variable. Lets say we''ve got the following variable located somewhere
in
our manifest ...

$vhost = "host-internal.test-domain.tld"

... and there might be a need to compare it with a string in order to
execute some peace of code:

if $vhostDomain == "test-domain.tld" {
    # create file if $variable contains domain name
    file { ''/some/file'': ensure => present }
}

Further more the $vhost variable is passed to a definition to create the
respective vhost. For the conditional to work the variable $vhostDomain
shall contain only the domain part of $vhost.

What about using regsubst here? I just played around with it a few times
but didn''t

I think that the split function won''t work because it splits the string
into three separate parts by using ''.'' as the delimiter and to
join them
back together (domain part + tld) doesn''t seem to be much practical.

Actually I solved my problem by using the "regsubst" function:

-------------------------->------------------------------
:~$ cat test.pp;
$vhost = "host-internal.test-domain.tld"
$vhostSplit =
regsubst($vhost,''[a-z\-]*\.(.*)'',''\1'')
alert $vhostSplit

:~$ puppet apply test.pp;
alert: Scope(Class[main]): test-domain.tld
--------------------------<------------------------------

Works like a charm, just what I was searching for ;)
