By carefully reading the code in `job_controller.go`, I finally understood that the back-off count is reset when `forget` is true, which happens when `active` or `successful` changes without any new failures right at the moment. That happens in this code: https://github.com/kubernetes/kubernetes/blob/dd649bb7ef4788bfe65c93ebc974962d64476b39/pkg/controller/job/job_controller.go#L588 That behavior does not match what this document says. My change fixes the doc to match the code. It might be better to fix the behavior to match the doc, since the behavior is kind of weird to describe. But I imagine that the Kubernetes team will need to consider factors I'm not aware of before deciding to change job back-off behavior, so I am not going to the effort of proposing a change like that.
