Kol Crooks developed and delivered a Pod Replacement disruption feature for the DataDog/chaos-controller repository, focusing on enhancing chaos engineering capabilities within Kubernetes environments. Leveraging Go and YAML, Kol designed an API that enables deterministic, end-to-end pod replacement simulations by cordoning nodes, optionally deleting persistent volume claims, and terminating target pods. The implementation introduced a MaxRuns cap to control disruption frequency, supporting more repeatable and controlled resilience testing. This work aligned with Kubernetes controller patterns and emphasized maintainability, expanding the system’s ability to validate recovery procedures and test failure modes. The feature deepened the project’s system design and operational robustness.
