What 429 chaos experiments taught us about Kubernetes operator resilience

This blog post explores chaos testing on Kubernetes operators through 429 experiments, revealing critical insights about resilience and error handling within the Kubernetes operator framework. It highlights the importance of comprehensive testing methodologies, particularly focusing on full spec enforcement and robust health checks. Notably, the author emphasizes that traditional chaos tests often do not capture deeper bugs specific to operator implementations, demonstrating that SDK-level tests can expose issues overlooked by standard CLI tests.
