In this episode of DevOps Daily with Fexingo, Lucas and Luna dig into a forgotten Kubernetes feature: PodPreset. Once hailed as a way to inject configuration into pods automatically, PodPreset was deprecated in 2022 and removed in Kubernetes 1.25. But many clusters still carry its legacy — and that legacy causes config drift that operators never see coming. Lucas explains how PodPreset worked, why it was retired in favor of admission webhooks and Operators, and how leftover PodPreset admission controller configurations can silently mutate pod specs. He walks through a real incident where a team spent weeks debugging mysterious container restarts, only to trace the root cause to an old PodPreset definition. Luna pushes on whether the Kubernetes ecosystem moves too fast for production stability. The episode ends with a forward-looking question: as Kubernetes sheds beta APIs and legacy features every release, are operators keeping up with the removal notices buried in release notes?
