What it shows

  • Kubelet evicts pods proactively before the Linux kernel OOM killer triggers.
  • BestEffort QoS pods without resource limits are terminated first.
  • Guaranteed pods are spared unless usage exceeds requested thresholds.

The takeaway

Setting precise resource limits protects mission-critical pods from eviction under node memory pressure.
