Hi,

I have two recipes my open source chef server and need to interchange some data between them. I wondering how to do that. If someone give a hint, it will much appreciated.

PS: I tried to write the data into a databag, but failed as below. It looks like recipes save data into a databag is allowed.

Net::HTTPServerException

Data bags can be a little awkward. A data bag is just a container into which you can put data bag items. Since the data bag part doesn't have any data, there's nothing to update, which is what you're trying to do here. For what you're trying to do, data bag items would work.

That said, for passing in-memory data between recipes within a chef run, you're better off setting node attributes or using the node.run_state hash.

 

Thanks,
