Currently, we handle this by using variables that we set when parsing site.pp.
We have a directory /etc/puppet/manifests/resources. In site.pp, we have
'import resources/*' before we have any node definitions. One of the files in
the resources directory may be something like sites.pp where we have something
like the following:
case $sitecode {
"FO": {
$ldapserver = 'foldap.domain.com'
$nameserver = ['192.168.2.2','192.168.2.3']
$searchpath = ['domain.com','fo.domain.com']
}
"RT": {
$ldapserver = 'rtldap.domain.com'
$nameserver = ['192.24.4.3','192.24.4.4']
$searchpath = ['domain.com','rt.domain.com']
}
}
Then just use the appropriate variable in your module. We also use this
approach to define site specific (or network specific) virtual resources so in
the modules we just realize all resources of a certain type.
It would be very easy to create an environment for each site/network you have
and then you could define a resources directory for each site/network instead
of having one that's full of conditionals.
