Explore Kubernetes controller development using Rust programming language in this 36-minute conference talk from DevConf.CZ 2025. Learn how to leverage Kubernetes API server's CustomResourceDefinitions (CRDs) extension layer to build controllers with enhanced functionality using Rust instead of the traditional Go-based approaches. Discover the structure and implementation patterns of Rust-based controllers, understand the compelling reasons for choosing Rust for controller development, and evaluate the advantages and potential drawbacks of this approach. Examine how Rust controllers can still integrate with and benefit from the established Go ecosystem within Kubernetes environments. Compare different implementation strategies between Rust and Go controllers while gaining insights from real-world projects that have successfully adopted Rust for Kubernetes controller development.
