How does kube-scheduler prevent starvation of low-priority Pods?

Senior Kubernetes
Quick Answer The scheduler uses priority-based preemption รขโ‚ฌโ€ high-priority Pods preempt lower-priority ones to get scheduled. For lower-priority work that can't preempt anything, the scheduler queues it and retries periodically. With proper Priority Classes and a mix of preemptible and non-preemptible workloads, high-priority work always gets scheduled while low-priority work waits rather than starving.

Answer

Fair scheduling and backoff ensure low-priority Pods eventually run.
