CRI-O's WASM Adventure: Challenges, Strategies, and What Lies Ahead - Sohan Kunkerkar & Peter Hunt, Red Hat
Many years our two heroes, CRI-O (a lightweight container runtime for Kubernetes), and WebAssembly, spent apart, honing their strengths for the adventure to come. Join us in this talk as we spin a tale describing the reasons why WASM support is essential for CRI-O, the challenges faced during its integration, such as runc's lack of support for WASM and the complexity of assigning the correct runtime to a pod, and the strategies employed to overcome these challenges. Additionally, we will outline our vision for the future of this integration, including handling WASM workload as container images and loading WASM plugins directly into CRI-O instead of NRI and how it will revolutionize the capabilities of CRI-O and Kubernetes. This talk is designed for developers, operators, weary travelers, and anyone interested in the intersection of Kubernetes, CRI-O, and WebAssembly.
