Puppet users - Aug 2009 - Exported Resources: noob help please!

Hi All,

I''m successfully using Exported Resources and StoreConfigs on my
puppet system. I''m able to populate the hosts files on all of my
nodes, and that''s pretty cool.

My problem is that i''m not quite clear how to query the information
stored in the Exported Resources database for other things. e.g., I
want to setup Postfix to allow relay from _all_ of the IPs that facter
has reported to the puppet master. How can I pull all of the IPs from
the database and turn them into puppet variable array?

I too would like to know how to pull like this from the stored config  
db...

I''m glad someone else out there feels the same way about Exported
Resources. I''ve resulted to using exported resources in a manifest to
have the local puppet on the puppetmaster write templates for other
modules which then get picked up by other nodes.

Messy stuff.

There has to be a better way to do this without manually defining all
of my IP addresses in variables?

Why don''t you collect and build those things directly on the node where
you need it?

Use something like the concatenated_file define[1]:

source:

   @@concatenated_file_part { "$ipaddress":
     dir => "/var/lib/puppet/ips",
     content => "$ipaddress\n",
     tag => ''ip''
   }

target:

   Concatenated_file_part <<| tag == ''ip'' |>>
   concatenated_file { "/etc/iplist":
     dir => "/var/lib/puppet/ips",
   }

This gives you a list of all $ipaddresses in /etc/iplist on the target.

David,how does the code you provided handle the removal of a "source"
node ? as far as i can tell the directory that contains the
concatenated_file_parts  doesn''t get purged on each puppet
iteration.so even after the   "source" node stops exporting its
file_part the Concatenated_file will contain its entry.
Maybe some time-stamp magic  is needed here ...

The directory where all thos parts land is "purged". So you need to 
delete the node from your stored configs (see the kill_node script on 
the wiki) or run it a last time with no classes at all. Then the file 
will vanish automatically on the next run on the target.
