🔹 Kubernetes - Kubernetes v1.34: Pod Replacement Policy for Jobs Goes GA

The tech blog post announces that the “Pod Replacement Policy” feature in Kubernetes v1.34 has reached general availability (GA). This feature provides users with control over when terminating Pods are replaced, addressing issues that arise when Pods are prematurely recreated, such as exceeding specified parallelism, scheduling delays, and unnecessary cluster scaling. Users can now choose between two policies: “TerminatingOrFailed” (default), which replaces Pods as soon as they start terminating, and “Failed,” which waits until Pods fully terminate. The blog includes an example of how to configure a Job using this feature and explains the implications for popular workloads, like TensorFlow, that require specific Pod configurations. It also provides links to further documentation and acknowledgments to contributors who helped develop the feature. Readers are encouraged to get involved with the Kubernetes community for ongoing development. 👉 Read more
