Using Hiera with Parameters set for the Puppet Node

[Thomas Biddle]

Is it possible to have Hiera look at a key set for the node first, before looking at other items in the hierarchy?

In particular - I'm using Puppet Dashboard and am setting keys & params for there, so I would like for any value set there for a node to be used over another item in the hiera hierachy. What value would I have to specify in the hierarchy for this, if it is possible?

Thanks,

TJ

Puppet OS 2.7.19 if that is necessary as well.

Only option I can think of would be to write a custom hiera backend that checks with the ENC for the value, and then setup your hiera.yaml so it looks there first.

If you specify the levels of your data hierarchy in the conventional way -- from most specific to least -- then the hiera() function should do what you want automatically.  Do not use hiera_array() or hiera_hash() for this purpose, as those are specifically intended for collecting values declared at all levels of your hierarchy.
