Title: RE: [chef] Prevent resource from triggering multiple times in a single run

I think you want to use an only_if or not_if guard for this situation. If this really is a remote_file resource (rather than just an example), you may also want to look into the create_if_missing action instead of the create action; I don't know if that solves your specific problem, though.

Subject: [chef] Prevent resource from triggering multiple times in a single run

remote_file “/var/tmp/somefile” do
     source “http://binfiles/somefile”
     owner “root”
     group “root”
     mode “0644”
     action :create
end

Lets just suppose that this is a somewhat expensive operation that may 
need to get called multiple times during a converge depending on what 
recipes the node is running. I would like to say “do not execute this 
resource if it has already been triggered during this run”

I would also not like to use a marker file if I can avoid it.

I know we have delayed execution but that is not what I want. I need 
this to trigger on the first call and then not again. Can I use the 
run_status or run_context to accomplish this?

Thanks!
