[chef] Re: Re: AWS cookbook and the run list

Should I be relying on the node['cloud']['provider'] instead?

So I added this to my metadata.rb:

depends 'aws'

Added this to my run_list:

    "recipe[aws]",
    "recipe[aws::ec2_hints]",

Added this to my recipe:

if node["ec2"]
  include_recipe "mycookbook::ec2_specific_thing"
end

Works great when I ran it on an EC2 instance. But when I tried a `vagrant up` for a local VM, it hits an error in my ec2_specific_thing recipe. I thought it wasn't going to be executed at all though. Any ideas?

Thanks!

Yep, you can do this:

if node['ec2']
  include_recipe 'myebsstuff'
end
