I was intending to set up some Chef environments for different parts of the

Taking the simple example of
how can I write a case statement to process differently according to whether
node is in primary, secondary or dmz?
I would create an ohai plugin to get the subdomain part. Something like this:
parts = fqdn.split(/\./)
You can distribute this to your nodes with Opscode’s “ohai” cookbook0.
% knife cookbook site install ohai
% $EDITOR cookbooks/ohai/files/default/plugins/subdomain.rb
# paste the code above
% knife cookbook upload ohai
Then add ‘recipe[ohai]’ to your nodes, and when chef runs, they’ll
have an attribute “subdomain”.
% knife node show virt1test -a fqdn
% knife node show virt1test -a subdomain
