puppet module environment from hiera

[Matthew Feinberg]

Hello

I have been attempting to set all my clients environments from a single yaml file rather than having a single file for each server.

I want to modify the puppet.conf.erb file to use a hiera lookup to get the enviornment from the env.yaml file  for that $::clientcert . 

Is this possible and can someone point me in the right direction on how to do this? I have tried 100 different options from google searches and nothing works. 

For example I have env.yaml

---

puppet-test.MYDOMAIN.com:

  - environment: testing

centos6-dev.MYDOMAIN.com:

  - environment: unstable

anotherhost.MYDOMAIN.com:

  - environment: stable

My hiera,yaml looks like

---

:backends:

  - yaml

:hierarchy:

  - env

  - environment/%{environment}

  - operatingsystem/%{operatingsystem}

  - node/%{fqdn}

  - common

:merge_behavior: deeper

:logger: puppet

:yaml:

  :datadir: /etc/puppet/hieradata

Not sure to have understood your question, which actually can probably find wider answers on puppet-users.

Anyway, just few notes, even if they might not be related to your case:

- In :yaml:  :datadir:
you can use environments and any top scope variables, for example:
 :datadir: /etc/puppet/hieradata/%{environment}

- In Puppet.conf is still not possible to have different hieradtaa for different environemnts.

- Puppet's environment internal variable is not necessarily related to your nodes' operational environment, for which, for example I generally use a fact or top scope variable called $end, which I often use in hiera's hierarchies

- You can you variables defined in Hiera on other hiera yaml files. For example:
wordpress::database_server: "%{hiera('instances::mysql::public_hostname')}" ( Check http://docs.puppetlabs.com/hiera/1/variables.html for details).

Hope some of these info might give you useful hints.
