------------------------------------
Resolution: Duplicate
> [Umbrella] Support K8s vertical pod auto scaling
> ------------------------------------------------
>
> Key: YUNIKORN-1765
> URL: https://issues.apache.org/jira/browse/YUNIKORN-1765
> Project: Apache YuniKorn
> Issue Type: Improvement
> Components: core - scheduler, shim - kubernetes
> Reporter: Peter Bacsko
> Assignee: Peter Bacsko
> Priority: Major
>
> The vertical pod autoscaler
> ([https://github.com/kubernetes/autoscaler/tree/master/vertical-pod-autoscaler])
> is a project which tracks the memory/cpu usage of pods and updates their
> resource limits/requests based on the monitored usage over time.
> From the Github docs: _"Vertical Pod Autoscaler (VPA) frees users from the
> necessity of setting up-to-date resource limits and requests for the
> containers in their pods. When configured, it will set the requests
> automatically based on usage and thus allow proper scheduling onto nodes so
> that appropriate resource amount is available for each pod. It will also
> maintain ratios between limits and requests that were specified in initial
> containers configuration._
> _It can both down-scale pods that are over-requesting resources, and also
> up-scale pods that are under-requesting resources based on their usage over
> time."_
> Currently, the "auto" (in-place) updater is not available, it only works with
> "recreate". However, it is only a matter of time and "auto" will work.
> Currently, Yunikorn can not handle pod updates of this kind and the scheduler
> core part isn't ready for this, either.
> This ticket is intended to track the necessary tasks to support VPA. More
> details will be added later when necessary.
