[chef] RE: Re: stopping recipe execution early

["Pitucha, Stanislaw Izaak" < >]

Thanks, I tried 'return' in shef, which failed, so I assumed it would fail in 
chef-client too. Apparently that's not the case.

chef:recipe > return
ThreadError: return can't jump across threads
        from (irb#1):1

Subject: [chef] Re: stopping recipe execution early

To expand; apologies: occasionally we'd skip the entire execution of a recipe 
depending solely upon the results from our Discovery [0] library cookbook.

A common (gated) execution pattern is:

return unless discovery_search("a_servers_role_that_ineed",
  :empty_ok => false,
  :environment_aware => true)

Cheers,
