LGTM.

Was this just a simple move of the package?
(guessing nothing changes for the resource itself as far as we're concerned)

Yeah, I just switched to using the latest version of the struct to deserialize the Ingress resources. This should be backward compatible (same approach is used for other resources), and the tests still pass, so hopefully this should do the trick.

I'm not sure this is backward compatible, as I got an error trying to use old Ingress schema when following this guide. I made some changes (pulumi/kubernetes-guides#38) after a tip from @jaxxstorm and it worked fine.

Besides that, think this comment should also be updated:

@cangussu Thanks for letting us know. I opened a new issue to investigate further.
