I have a set of Pods running commands that can take up to a couple seconds. There is a process that keeps track of open request & which Pod the request is running on. I'd like the use that information when scaling down pods - either by specifying which pods to try to leave up, or specifying which pods to shut down. Is it possible to specify this type of information when changing the # of replicas, e.g. I want X replicas, try not to kill my long running tasks on pods A, B, C?
i've been looking for a solution to this myself, and i also can't find one out of the box. however, there might be a workaround (would love it if you could test and confirm)
steps:
1. delete replication controller
2. delete X desired pods
3. recreate replication controller of size X
