Dear chefs,
according to this list thread from Jan of this year
http://lists.opscode.com/sympa/arc/chef/2014-01/msg00340.html, it is
necessary to hint Ohai when running inside an EC2 VPC. Is this still the
case?
cheers,
Bryan W. Berry
Hey Bryan,
I believe this is still the case considering last week I pulled in the latest ohai cookbook and the node[:ec2] attribute was not populated in my ec2 vpc (kind of annoying). I had to use the ohai_hint lwrp and reload ohai directly afterwards. Few things to note though, make sure and provide a value for the ec2 hint. I ended up just putting { "type" => "vpc" } for the content attribute to the ohai_hint lwrp (otherwise the ec2.json file will not be created - see the provider code for why this is). You'll also have to make sure and run the ohai_hint and ohai reload in the convergence phase if you use the node[:ec2] anywhere during that phase. Hopefully ec2 vpc detection can be detected in the near future.

Is there an issue or PR for this on github? I'd like to follow it for
future reference.
TIA,

I don’t think there’s any open issues for this, you can poke through the old ticketing system (https://tickets.opscode.com/secure/Dashboard.jspa) to find the discussions for why things are the way they are now. Tl;dr, there isn’t a reliable way to tell if you’re on EC2 that doesn’t involve network calls (which could take a long while to time out depending on your network topology). Until Amazon does something about that, there’s nothing we can do in ohai.
