Yikes. When I originally posted I cleaned up identifiable and I took
away too much. I actually was passing everything through like I should.
Since I deleted my test data from the original post, Here's the hiera
data I am having trouble with:
ucb::mail::senders:
"@%{::clientcert}":
relay: 'berkeley.edu'
And the resulting hiera call that returns the unexpected entry:
# hiera -h ucb::mail::senders ::clientcert=myhost.ist.berkeley.edu
::environment=arusso_postfix ::fqdn=myhost.ist.berkeley.edu -c
/etc/hiera-test.yaml
{"@%{::clientcert}"=>{"relay"=>"berkeley.edu"},
"@myhost.ist.berkeley.edu"=>{"relay"=>"berkeley.edu"}}
It looks like hiera is doing it wrong - it ends up adding the
interpolated key to the hash without removing the original.
Is the hiera_hash function doing the same from within puppet?

The template generated on the host also reflects the fact that the extra
entry is being sent over. I also tried it with other facts, like fqdn
and hostname, and confirmed they all exhibit the same behavior.
Thanks,

Hi,
running hiera from the command line, you have to provide the
variables you use yourself like
hiera somekey clientcert=node.example.net <http://node.example.net>

*Subject:* [Puppet Users] Unexpected behavior when using
variable interpolation on a subkey in hiera
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
<http://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
<http://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
