Variables in a single-quote is changed to value - should not be (according to the README)

[khdevel]

Affected Puppet, Ruby, OS and module versions/distributions

Puppet v3.8.4

What are you seeing

In the /etc/puppet/hiera.yaml the values in a hierarchy are completed strings but should be with some variables. According to the README it should work in other way.

What behavior did you expect instead

After the puppet executes the code my hiera.yaml file looks as below:

:hierarchy:
  - hieradata/host_type/dev/foreman

But should...:

:hierarchy:
  - "hieradata/host_type/%{::deployment_group}/%{::host_type}"

If I "escape" the special characters I have a mess in my hiera.yaml:
Configuration:

classes:
  - hiera
hiera::hierarchy:
  - 'hieradata/host_type/\%\{\:\:deployment_group\}/\%\{\:\:host_type\}'

Output:

:hierarchy:
  - 'hieradata/host_type/\x5c%\x5c{\x5c:\x5c:deployment_group\x5c}/\x5c%\x5c{\x5c:\x5c:host_type\}'

How did this behavior get triggered

My configuration for THIS host in hieradata is:

classes:
  - hiera
hiera::hierarchy:
  - 'hieradata/host_type/%{::deployment_group}/%{::host_type}'

Output log

Any additional information you'd like to impart

Well, in fact README doesn't explain the way to "feed" class parameters via hiera itself. According to this ticket, you must define your hierarchy this way:

hiera::hierarchy:
  - 'hieradata/host_type/%%{}{::deployment_group}/%%{}{::host_type}'

At least, this solved the problem for me.

Thank you very much ortegaga, finally someone read my issue :) I will check it today!

@khdevel I assume your tests were successful.
