Overview

This folder holds a sample plugin implementation based on the number of terminating and nominated Pods on a Node.

Maturity Level

  • 💡 Sample (for demonstrating and inspiring purpose)
  • 👶 Alpha (used in companies for pilot projects)
  • 👦 Beta (used in companies and developed actively)
  • 👨 Stable (used in companies for production workloads)

Pod State Plugin

This is a score plugin that takes terminating and nominated Pods into accounts in the following manner:

  • the nodes that have more terminating Pods will get a higher score as those terminating Pods would be physically removed eventually from nodes
  • the nodes that have more nominated Pods (which carry .status.nominatedNodeName) will get a lower score as the nominated nodes are supposed to accommodate some preemptor pod in a future scheduling cycle.
