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

[Greg Barker < >]

I was hoping to avoid adding complexity to the run list by creating a new environment for EC2 and having to specify the env_run_lists in my base role. If I'm going down that route I would probably just put mycookbook::ec2_specific_

thing on the run_list there, which negates the necessity for using if node["ec2"].

It seems like a much simpler way to solve it would be something like:

if !node["ec2"].empty?
  include_recipe "mycookbook::ec2_specific_thing"
end

Or maybe relying on another attribute like node['cloud']['provider']?

Or am I crazy for trying to avoid env_run_lists here?

Ah yes. I missed the first part of Greg's email that stated that his
run_list contains recipe[aws::ec2_hints]. So... maybe not a good thing
to do when running under Vagrant :-)
