Spin extension

Installation

See Installing Extensions.

Usage

In order to create the Wasm workload, a runtimeclass needs to be created.

apiVersion: node.k8s.io/v1
kind: RuntimeClass
metadata:
  name: wasmtime-spin-v2
handler: spin

Testing

Apply the following manifest to run sample pod using spin:

apiVersion: v1
kind: Pod
metadata:
  name: spin-test
spec:
  containers:
  - command:
    - /
    image: ghcr.io/spinkube/containerd-shim-spin/examples/spin-rust-hello
    name: spin-test
  runtimeClassName: wasmtime-spin-v2

The pod should run without any errors:

$ kubectl get pods
NAME            READY   STATUS      RESTARTS   AGE
spin-test   1/1     Running   0          28s
