Re: [Puppet Users] Why IF-ELSE not work?
Import is like a #include in C: it's essentially a preprocessor directive and
is evaluated before the if/ else.

Why it didn't work? If I run puppet-agent, it read all pp-files and crash on

incorrect?

Re: [Puppet Users] Why IF-ELSE not work?
Hi,
import is largely deprecated for most uses. I haven't really used it
after Puppet 0.25.
What I learned back then was that the parser would honor all import
statements it would find. I believe that the if statements cannot be
validated until after the parsing stage, so they won't hinder importing.
Instead of relying on import based construct, make sure all your
resources are organized in trees of classes, and that each platform only
*includes* its appropriate tree root.
HTH,
Felix

I want call diffrent manifest files for diffrent rules and systems. I think that write all rules in one file is not good idea :-) четверг, 14 февраля 2013 г., 18:41:33 UTC+4 пользователь jcbollinger написал: On Thursday, February 14, 2013 5:55:35 AM UTC-6, blalor wrote: Import is like a #include in C: it's essentially a preprocessor directive and is evaluated before the if/ else. http://docs.puppetlabs.com/puppet/2.7/reference/lang_import.html But also, as I just remarked in another thread, 'import' causes the specified manifest to be parsed as a standalone manifest file.

No one suggested that you should put everything on one file. Nevertheless,
you cannot call a manifest in the sense of a function. Puppet DSL is not
a scripting language, and manifests are not executable in any meaningful
sense. You need to get your head around that (among other things) to
become proficient with Puppet.
Instead of thinking in terms of files, you should be working on modeling
your target systems via classes. If you lay out your classes in the
recommended (and autoloader-supported) way, then the distinction will be
thin, as you will have only one class or definition per file. The point,
however, is to harmonize your mental model with the way Puppet actually
works.
In your case, you might write site.pp like this:
manifests/site.pp
---
# Prefer to avoid top-scope declarations other than node blocks,
# class definitions, and defined-type definitions
node default {
# prefer to put logic in classes, keeping node blocks simple
include 'site'
}
with a module site defined by:
modules/site/manifests/init.pp:
---
class site {
case $operatingsystem {
redhat: { include 'site::redhat' }
centos: { include 'site::centos' }
windows: { include 'site::windows' }
default: { include 'site::default' }
}
}
modules/site/manifests/redhat.pp
---
class site::redhat {
# declarations for redhat systems
}
And similar classes site::centos, site::windows, and site::default as well,
each in its own file.

[Puppet Users] Why IF-ELSE not work?
I try include different .pp for my systems. site.pp like:
if $operatingsystem == 'debian' {
import '../my/os/linux/debian.pp'
}
elsif $operatingsystem == 'windows' {
import '../my/os/windows/windows.pp'
}
else {
import '../my/os/default/default.pp'
}
and I try CASE:
case $operatingsystem {
redhat: { import '../my/os/linux/redhat.pp' }
centos: { import '../my/os/linux/centos.pp' }
windows: { import '../my/os/windows/windows.pp' }
default: { import '../my/os/default/default.pp' }
}
Why it didn't work? If I run puppet-agent, it read all pp-files and crash
on windows-parameters on Linux or on linux-parameters on Windows. What I do
incorrect?
