Usage

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

apiVersion: node.k8s.io/v1
kind: RuntimeClass
metadata:
  name: wasmedge
handler: wasmedge

Testing

Apply the following manifest to run sample pod using wasmedge:

apiVersion: v1
kind: Pod
metadata:
  name: wasmedge-test
spec:
  restartPolicy: Never
  runtimeClassName: wasmedge
  containers:
  - name: wasmedge-test
    image: wasmedge/example-wasi:latest

The pod should run without any errors:

$ kubectl get pods
