Greetings,
I'm having trouble using hiera variable interpolation on a sub-key. It
appears that along with interpolating the variable, hiera is also returning
the un-interpolated data as well, which is causing issues because the
un-interpolated data is nonsense. I'm currently running Hiera 1.3.4 and
Puppet 3.8.5 on RHEL6.
Here's an example of what I have in hiera:
# common.yaml
somekey:
"%{::clientcert}":
subsubkey: "data"
And here's what I get when I query hiera directly:
$ hiera -h somekey
{"myhost.example.com"=>{"subsubkey"=>"data"},
"%{::clientcert}"=>{"subsubkey"=>"data"}}
Oddly enough, if I run it without the -h flag, I only get the
un-interpolated data.
$ hiera somekey
{"%{::clientcert}"=>{"subsubkey"=>"data"}}
Based on my reading of the docs[1], in both cases I would expect to get
back: {{"myhost.example.com"=>{"subsubkey"=>"data"}}
I also tested variable interpolation with the value of subsubkey, and hiera
properly interpolated it correctly, even on the returned entry where
%{::clientcert} was left un-interpolated.
Initially I thought this was somehow related to deep_merge, but I tested it
out by disabling deep_merge (removing the merge_behavior key) and I get the
same results.
Am I misunderstanding how interpolation on sub-keys in hiera should work,
or is this unintended behavior?
Thanks,
Aaron
