Pod Priority Classes 2026

Priority classes prevent low-priority pods from starving the cluster. The pattern.

Levels

system-critical, high, default, low. Each with priority value.

Higher: scheduled first; preempts lower.

Mixed-criticality clusters. Production + batch jobs.

Catches the case where batch starves prod during scaling.

Everything system-critical. Defeats the system.

Most pods should be default.
