🎓 LEVEL 49 DEBRIEF: PriorityClass

Congratulations! PriorityClass mastered!

Priority & Preemption

PriorityClass assigns importance to pods.

apiVersion: scheduling.k8s.io/v1
kind: PriorityClass
metadata:
  name: high-priority
value: 1000  # Higher value = higher priority
preemptionPolicy: PreemptLowerPriority

Preemption: Scheduler evicts lower priority pods to make room for higher priority.

Priority Values

  • System-critical: 2000000000+ (reserved)
  • Production-critical: 1000-10000
  • Production: 500-999
  • Development: 100-499
  • Batch/test: 0-99

Key Takeaways

  1. Higher value = higher priority
  2. Preemption evicts lower priority pods
