Using hiera to manage hiera

[electrical]

Hi,

I got the following in a hiera file:

https://gist.github.com/electrical/731539930ef79f48b93a

The issue is now that the values get evaluated and the result of those get passed in the hiera.yaml file instead as is.
Is there a way to avoid that?

Cheers.

I actually have never been brave enough to declare puppet-hiera using hiera values. The actual template for hiera.yaml doesn't contain any quotes though, so I'm not sure where either your ' or " quotes are coming from.

Hi

The gist is what I placed in the hiera data file.
The result is that the variables get evaluated and placed in the hiera.yaml
file.

We use Hiera's %{} to escape interpolation, looking somewhat like this:

# In /etc/puppet/hieradata/production/fqdn/puppet01.example.com.yaml
puppet::master::hiera::hierarchy:
  - "fqdn/%%{}{::clientcert}"
  - "stages/%%{}{::stage}"
  - "domains/%%{}{::domain}"
  - "os/%%{}{::operatingsystem}/%%{}{::lsbdistcodename}"
  - "os/%%{}{::operatingsystem}"
  - "virtual/%%{}{::virtual}"
  - #...

The %{} construct is undocumented and should probably not be relied upon. The correct way would be to use the Hiera function literal('%'), which I find a bit unwieldy. See https://tickets.puppetlabs.com/browse/HI-127 for details.

Note that we don't use @hunner's module directly but I have implemented more or less exactly the same thing in our own puppet-puppet module.

@antaflos ah cool. thanks for the info. Will try the literal('%') function.
