How to run WebAssembly applications on Rancher Desktop?

Starting v1.13.0, Rancher Desktop has added experimental support for running WebAssembly (Wasm) applications. In this video, we explore using this feature and deploying a sample #wasm app on the k3s #kubernetes cluster that comes bundled with Rancher Desktop.

Why use Kubernetes? Why not show a demo for the simplest possible way to spin up a wasm app, analogous to spinning up a docker container?

[@Rancher]

Heya, that's a great question!
There are two major reasons for this:
1. The value prop of a Wasm module is its capability to run anywhere - whether in a VM, on a desktop, in a browser, in Kubernetes, or on the edge. This is what we wanted to emphasize with us using the bundled k3s.
2. Rancher Desktop does support the other use case that you asked about - running a Wasm module using the inbuilt dockerd/moby runtime. Unfortunately, containerd is yet to receive that support because of the nerdctl bug.
