Hiera + Puppet classes

puppet

I'm trying to figure out Puppet (3.0) and how it relates to built-in Hiera. So this is what I tried, an extremely simple example (I'll make a more complex hierarchy when I manage to get the simple one working):

# /etc/puppet/hiera.yaml
:backends:
  - yaml
:hierarchy:
  - common
:yaml:
  :datadir: /etc/puppet/hieradata

# /etc/puppet/hieradata/common.yaml
test::param: value

# /etc/puppet/modules/test/manifests/init.pp
class test ($param) { notice($param) }

# /etc/puppet/manifests/site.pp
include test

If I directly apply it, it's fine:

$ puppet apply /etc/puppet/manifests/site.pp
Scope(Class[Test]): value

If I go through puppet master, it's not fine:

$ puppet agent --test
Could not retrieve catalog from remote server: Error 400 on SERVER: Must pass param to Class[Test] at /etc/puppet/manifests/site.pp:1 on node <nodename>

What am I missing?

EDIT:

I just left the office but a thought struck me: I should probably restart puppet master so it can see the new hiera.conf. I'll try that on Monday; in the meantime, if anyone figures out some not-it problem, I'd appreciate it 🙂

I am an idiot, and the edit in the question was correct: after restarting puppet master, everything worked fine.

Wrapping defined types in classes – puppet

Two things regarding your puppet code.

The define should be in it's own file (named add_user.pp, and located in the <modulename>/manifests/ folder) , rather than in the class file.

Set the define up (change $name to $username, as $name is a reserved variable), and then add the same set of parameters as the define uses to the class. (which in your example would be $modulepath/users/manifests/add.pp to make it work with the autoloader)

If you change the class as follows:

class users::add( $u_name, $u_comment, $u_home, $u_shell, $u_uid, $u_gid, $u_password)
{
  users::add_user{ $u_name:
    $username => $u_name, 
    $comment  => $u_comment, 
    $home     => $u_home, 
    $shell    => $u_shell, 
    $uid      => $u_uid, 
    $gid      => $u_gid, 
    $password => $u_password,
  }
}

And change the site.pp to:

 import "classes/*.pp"
    node default{
      class { 'add_user': 
        username => "saga",
        comment => "Arun Sag",
        gid => "100",
        home => "/home/saga",
        password => '$1$passwordhash/',
        shell => "/bin/bash",
        uid => "70960",
      }
    }

For the yaml, something like this will do it, please refer to the documentation for more details:

---
classes:
  users::add:

parameters:
  name: some_name
  comment: some_comment
  home: home_value
  shell: /bin/sh
  uid: 3990
  gid: 3990
  password: superstrongpassword

environment:
  production

Hiera can’t find puppet environment

There are multiple ways to feed hiera facts. Try hiera -d blah environment=development.
