CRI-O

v1.33.13Kubernetes Core

2026年6月3日リンクをコピー

Single-fix patch release resolving a race condition that caused CRI-O to incorrectly report exit code 255 for fast-exiting containers.

• breakingFalse exit code 255 may have masked real container failures

  If your monitoring, alerting, or restart policies key off exit code 255, you may have been misclassifying fast-exiting containers as crashed. After upgrading, audit any runbooks or OOMKill/CrashLoopBackOff workflows that treat exit code 255 as a specific signal — the real exit codes from short-lived containers will now surface correctly.

• enhancementUpgrade straightforward for 1.33.x users — no config or dependency changes

  This is a clean drop-in replacement for v1.33.12. No dependency bumps, no config changes required. Plan a rolling node drain and replace the CRI-O binary. Prioritize nodes running batch jobs, init containers, or short-lived workloads where fast exits are common and exit code accuracy matters most.
