Discover essential patterns for designing and implementing Kubernetes operators in this informative conference talk. Explore key challenges faced when developing mature operators using kubebuilder and operator-sdk to manage workloads and infrastructure. Learn valuable lessons from years of experience in real-world operator design and implementation across various use cases. Focus on Go-based operators and gain insights into API anti-patterns, bridging the gap between imperative infrastructure management and declarative Kubernetes API, optimizing client cache usage, efficiently interacting with multiple clusters, and minimizing API server load. Equip yourself with the knowledge to enhance operators with new features and evolving APIs while overcoming common pitfalls in operator development.
