Taking Service Mesh a Step Further with WebAssembly

on YouTube ↗30m

" summary

Shows how Envoy loads WebAssembly modules compiled from TinyGo and AssemblyScript using the wasme CLI, packages them as OCI artifacts and pushes to webassemblyhub.io registry. Demonstrates building a header‑adding module (tagged 0.14/0.15), deploying it to Istio 1.7 by injecting an Envoy wasm filter into Bookinfo pods, and verifying the added header appears in requests. Notes wasm support just merged upstream and targets Envoy 1.17 but remains experimental and needs soak time.
