hiera "environmentss" question

[Guy Matz]

Hi!  I am using environments in my puppet setup, and would like to do the same for hiera.  I used to have this sort of hierarchy:
:hierarchy: - hosts/%{fqdn}
                - domain/%{domain}
                - whatever/%{some_fact}
                - common

with a yaml datadir:
:yaml:
   :datadir: - /etc/puppetlabs/puppet/hieradata

I would like to append %{environment} to my datadir in order to get separation, however it looks like I can't and will have to do this:
:hierarchy: - %{environment}/hosts/%{fqdn}
                - %{environment}/domain/%{domain}
                - %{environment}/whatever/%{some_fact}
                - %{environment}/common

Can anyone verify that appending %{environment} to datadir won't work?  Does anyone have a good way of separating hiera environments?

Thanks a lot!
Guy

I'm using the following which I copied from somewhere. Quotes might be
part of the missing magic. Also I'm not sure you'd want a - in there
either.

:yaml:
:datadir: '/home/puppet/environments/%{environment}/hieradata'

I would use double-quotes for string interpolation, but this should work.  I've used this in a couple of on-site engagements, and it has worked well for us.

I can attest to the fact that it works fine here is my:

:yaml:
        :datadir: '/etc/puppet/env/%{environment}/hieradata'

I am having no issues with that.

I don't think this is correct. If it were, my config should not work at
all. In this case single or double quotes should both work. It's my
understanding that hiera.yaml is a data file that is going to be parsed
and then consumed by Puppet where things like variable interpolation
would happen. There isn't any variable interpolation during the parsing
so single quotes are more correct.

that's correct yeah

[Gary Larizza]

Yep, like RI said you're totally correct here.  Thanks for correcting :)

Hmmm . .   anyone have any idea why environment would not be getting interpolated?
Cannot find datafile /etc/puppetlabs/puppet/%{environment}/hieradata/10-host/gmatzpupnode.yaml

I have the following in my node's puppet.conf [agent] section:
environment = default

thanks again,
Guy

I see a few possible problems. Have you configured a default environment
on the Puppet master? Puppet uses the environment 'production' when
nothing is set. Also does ./puppet/default/hieradata/ exist and are the
the rest of the paths correct based on what you've set in your hiera.yaml?
