Puppet 3 (rc3) / Hiera 1 (rc4) / Hiera-puppet 1 (rc2)

[llowder]

This email is mostly for Kelsey Hightower's benefit, but by no means is exclusively for him.

On Ubuntu 12.04 (32bit, 'server'), after installing puppet 3 (rc3) hiera 1 (rc4) and hiera-puppet (rc2, from source)

These are the steps I took to get hiera/hiera-puppet working:

---
mkdir –p /etc/puppet/modules/hiera-puppet/lib/{hiera/backend,puppet/parser/functions}

cp /usr/lib/ruby/1.8/hiera/scope.rb /etc/puppet/modules/hiera-puppet/lib/hiera/
cp /usr/lib/ruby/1.8/hiera/backend/puppet_backend.rb /etc/puppet/modules/hiera-puppet/lib/hiera/backend/

cp /usr/lib/ruby/1.8/puppet/parser/functions/hiera* /etc/puppet/modules/hiera-puppet/lib/puppet/parser/functions

wget -O /etc/puppet/modules/hiera-puppet/lib/hiera_puppet.rb https://github.com/puppetlabs/hiera-puppet/blob/1.0rc/lib/hiera_puppet.rb

---

At this point, explicit hiera calls will work:

$a_user = hiera('apache_username')

notice("The value is: ${a_user}")


and normal (non explicit hiera usage) parameterized classes IF (AND ONLY IF) you specify values for all params will work.

  # -- Basenode -- #
  class { 'basenode':
    is_puppet_master => true,
    apt_host         => 'repo.XXXXX.com'
  }

However, param classes with defaults and no (or some) values specified still fail:

  # -- Basenode -- #
  class { 'basenode':
    is_puppet_master => true,
  }

However....

After one successful, partial run I now get the following error when trying to run puppet:
