Eviction vs Preemption
Both kick pods. Different reasons.
Live workflow · 3 working · 1 queuedLive
Signal · gather Working
Decide · pick action Working
Apply · with verify Working
Learn · update playbook Queued
Eviction
Resource pressure. Pod removed; not necessarily replaced.
Memory full, disk full.
Preemption
Higher-priority pod needs space. Lower-priority preempted.
Graceful for the higher pod.
Respond
Eviction: address resource pressure. Preemption: review priority classes.
Different fixes.
