Node or Role Attribute reference via Chef::Resource::Script::Bash

Chef Infra (archive)

All,
I apologize if this is a rather basic question, but I cannot seem
to find a clear answer. I am trying to pull a node or role based
attribute into only_if or not_if logic within a Bash block, though so
far without a lot of luck. A> Is it possible? B> If so, how?

Thanks,
David

Sure, does something like this not work?

$ chef-apply -s
execute 'echo hi' do
only_if { node['hostname'] == 'foobar' }
end
Recipe: (chef-apply cookbook)::(chef-apply recipe)

  • execute[echo hi] action run (skipped due to only_if)

Thanks Julian,
I was over thinking the problem and ended up with something far
less elegant. I appreciate the help.

Cheers,
David
