Ellison is right, it really doesn't make much sense to create one resource
with create_resources. In fact, I'm not even sure it will work with
classes because I've never tried it. However, it works great for defined
types. I think I understand what you're trying to do so let me give an
example of how you could accomplish it.
I *think* your goal is to be able to define not only parameters in hiera
but also classes to be applied to a node. You need an additional piece in
your site.pp file to do this.
include hiera_array('classes',['hiera','puppet'])
The array at the end is optional, and represents defaults. In our case, we
included hiera and puppet classes as defaults because there was a chicken
and the egg scenario on the puppet master. That's above and beyond this
example, though. What the above will do is collect all values defined as
an array called "classes" from hiera. It will merge results all the way
down the hierarchy so you can define your 'base' classes in your global
hiera file and get more specific as you go down and it will all be picked
up. In hiera, define classes like this:
---
classes:
- 'class1'
- 'class2::foo'
- 'class3::bar'
- etc
Then you can go about adding any parameters that need defined for those
classes:
class1::param1: 'boom'
class2::array1:
- 'foo'
- 'bar'
- 'baz'
class2::param2: 'thing'
That's it. You're done. I hope this helps. Please let me know if you
need more help with this example.
