Re: [Puppet Users] Help with NTP module provided by puppetlabs
Hi,
If you have Foreman configured as an ENC, the location parameter will be
available to Hiera as a fact. e.g. In the master section of puppet.conf,
you'll have something like (node.rb comes from Foreman):
external_nodes = /etc/puppet/node.rb
Then in hiera.yaml you can reference the location fact with
#{::location}. Parameters such as location are passed to puppet from an
ENC through the hash structure described at
https://docs.puppetlabs.com/guides/external_nodes.html#enc-output-format
Cheers,
Richard

Hi Richard,
Just wondering, I do have now a locations configured on my Foreman
(:locations_enabled: true), how can I access this data?
For example if I have a Facter variable named $location or $os_version
so I can use it on mypuppet scripts. How can I use Foreman locations
variable?
Hope I made myself clear :)
Thanks,
EddieM

Hi Martin,
Thanks for the help. I used the second approach.
1) I’ve created custom fact to identify the server location (I’m using the
timezone fact) – Now I’m able to identify all my servers by location.
2) I’m not sure about the second part “put ntp::servers into the appropriate
hiera data hierarchy” – I’m using Foreman and NOT Puppet enterprise if it
matters. Can you elaborate more how to implement it right, maybe add some
code if possible.
Hiera is not related to Puppet Enterprise.
Hiera is a data backend for automatic parameter lookups.
see http://docs.puppetlabs.com/hiera/latest/
You need to create a hiera.yaml config file.
The config file may look like this:
:backends:
- yaml
:yaml:
:datadir: ‘/etc/puppet/data’
:hierachy:
- “nodes/#{::certname}”
- “location/#{::timezone}”
- global
In your hiera data directory you can provide yaml files for hierarchies (you
don’t have to, but you can!)
/etc/puppet/data/
- nodes/foo.bar.domain.com.yaml # has host specific parameters
- location/CEST.yaml # has parameters for CEST timezone
- location/PDT.yaml# has parameters for PDT timezone systems
- global.yaml # has global parameters
Hiera parses the data hierarchy and uses the first match.
To allow dynamic data lookup the variable names from the module have to be
prefixed with the class name where they are used.
Note: this only works with parameterised classes, not with normal variables
inside a manifest.
With foreman you should also be able to create a group setting based on
timezone fact (I don’t have access to foreman right now, so I can not verify).
Best,
Martin
Thanks,
EddieM

Several solutions:
