hiera scope and hiera-foreman

[Christian McHugh]

Hey all,

I've been messing around with the hiera-foreman backend to see if it would let me migrate to hiera and use foreman and an ENC. 

https://github.com/torrancew/hiera-foreman

It works by querying each node's yaml file from foreman. Currently this code works when called from the hiera command line with the -m (mcollective option). It uses the mcollective facts to pull the fqdn variable to know which node to grab the yaml for. So far so good. However, this breaks when you attempt to use it as a hiera backend in a puppet module, since it no longer has the mcollective facts, and fqdn available to it. 

So my question is, what is the recommended way of querying the current hostname(s) in a hiera backend for it to know what host it should lookup the needed yaml? 

Thanks!

Okay. I figured out my issue. 

I'm not a developer so this is probably ugly, but came up with:

        begin

          fqdn = scope.catalog.tags[4]

        rescue

          fqdn = scope['fqdn'] if scope.has_key?('fqdn')

          Hiera.debug("trying mcollective")

        end

        Hiera.debug("got fqdn #{fqdn}")

That fqdn with both:

puppet master --debug --compile FQDN

and

hiera -d -c /etc/puppet/hiera.yaml -m FQDN
