Go Containerless on Kubernetes with WebAssembly and Rust

on YouTube ↗28m

" summary

Shows a Rust web app compiled to the wasm32-wasi target using warp and tokio, packaged with buildah as an OCI artifact, pushed to Docker Hub, and deployed to a Kind cluster with a custom runtimeClass pointing at a wasmEdge runtime; deployment uses two replicas, service on port 8080, and the module runs directly via containerd/runi. Claims: much smaller binaries, near-zero cold starts and near-native speed. Demo mostly works locally but hits a DNS resolution bug when contacting external APIs from the Kind cluster.
