Wasm and Containers Deep Dive
summary
A Docker Desktop technical preview released yesterday can run WebAssembly modules locally via Docker and containerd and deploy the same image to Kubernetes using a runtimeClass that points at containerd shims. The demo builds a Rust hello-barcelona wasm32-wasi module, pushes it to Hub as a multi‑platform image, and runs it with a wasm32-wasi runtime showing no OS, faster startup and sandboxing. The containerd-aware shim library runwasi (now donated to containerd) implements start/kill/delete/wait and the setup succeeds.
