What is the difference / advantage of
hierarchy:
- name: "Role data"
path: "roles/%{facts.category}.yaml"
and
hierarchy:
name: "Role data"
path: "roles/%{facts.category}.yaml"

Re: [Puppet Users] Include Hiera Classes
Well the exact answer to your question is:
lookup("roles::${category}::${class}::classes", Array, 'unique').include()
However, the code you've shown is implementing a hierarchy for class
assignment duplicative of the Hiera hierarchy. Why not use Hiera's
hierarchy to your advantage?
hiera.yaml:
hierarchy:
- name: "Role data"
path: "roles/%{facts.category}.yaml"
Then have an array named classes, and just use
lookup('classes', Array, 'unique').include()
Much easier. Don't make your own hierarchy, make use of Hiera.

Re: [Puppet Users] Include Hiera Classes
Do yourself a favour, define puppet classes and resources in puppet code. There
are surprisingly few people who can look at puppet resources in yaml and
conceptualize which portion is causing that odd ruby+yaml error.
This is a useful model for how to lay that out:
https://puppet.com/docs/pe/2018.1/the_roles_and_profiles_method.html
If you keep only the most significant items in hiera it will be much easier to
read. Albeit that it's older documentation, this section has the best phrasing
I've found for this so far:
https://puppet.com/docs/pe/2016.4/r_n_p_full_example.html#the-rules-for-profile-classes
Quoth:
* If your business will always use the same value for a given parameter,
hardcode it.
* If you can’t hardcode it, try to compute it based on information you already
have.
* Finally, if you can’t compute it, look it up in your data. To reduce lookups,
identify cases where multiple parameters can be derived from the answer to a
single question.
(But maybe not hard-hardcode it, put it in a puppet variable or something.)

[Puppet Users] Include Hiera Classes
Hi,
I want to include hiera classes.
---
roles::webserver::apache::classes:
- my_apache
roles::backup::bacula::classes:
- bacula
roles::timeserver::ntpd::classes:
- ntpd
roles::databaseserver::mysql::classes:
- mysqld
I used to use the follwoing (ugly) code in nodes.pp to do so:
if ($roles) {
$roles.each |$category, $classes| {
if ($classes) and (category) {
$classes.each |$class| {
if ($class) {
hiera_include ("roles::${category}::${class}::classes", {})
}
}
}
}
}
Is there a better way e.g. using lookup?
Thank you!
