Running WebAssembly Applications on Kubernetes with WasmEdge - Mirantis Labs Tech Talks

Explore the integration of WebAssembly applications with Kubernetes using WasmEdge in this 29-minute tech talk. Learn about WebAssembly's potential for deploying portable code with near-native performance and its growing ecosystem. Discover how to create and run a Wasm module on a slim container deployed on Kubernetes through a live demonstration. Gain insights into the advantages of using WebAssembly in cloud-native development, whether alongside containers or VMs. Follow along with the provided prerequisite tooling, including Rust, WasmEdge, Docker Desktop, and Lens. Delve into topics such as WebAssembly basics, Wasm modules vs. container images, common use cases, and WasmEdge functionality. Examine alternative WebAssembly tools and consider the technology from an operator's perspective. Conclude with additional resources for further exploration of WebAssembly and WasmEdge.
