This is really late for 1.6 - do we really have to do this?

@smarterclayton I don't see this as release blocking, but current kubectl describe currently shows the creator as Controller, not the actually controller from ControllerRef. This may cause user confusion.

"Controller" is probably one of the most overused words in the community. How about "Controlled By"?

@janetkuo Since this is not release-blocking, we should move it to the v1.6.1 or v1.7 milestone.

@janetkuo janetkuo modified the milestones: v1.7, v1.6 Mar 20, 2017

I am wondering if created-by is used for anything else that the controller ref cannot. Can you spawn a separate issue to deprecate it and start removing it from places we can while keeping backwards compatibility?

/lgtm but I thought we wanted to deprecate created-by in favor of controller ref. Separate issue for discussing.
