Description

Description

What problem are you trying to solve?

SIG Autoscaling has been working on an API for users to declare a buffer\headroom: kubernetes/autoscaler#8151

This would solve the following problems for Karpenter users:

  • Kueue Integration
  • Scheduling latency improvements for sensitive applications
  • pod headroom

Karpenter should support this Buffer API by accommodating it in its scheduling and consolidation algorithms.
