| # WasmEdge extension | ||
|
|
||
| ## Installation | ||
|
|
||
| See [Installing Extensions](https://github.com/siderolabs/extensions#installing-extensions). | ||
|
|
||
| ## Usage | ||
|
|
||
| In order to create the Wasm workload, a runtimeclass needs to be created. | ||
|
|
||
| ```yaml | ||
| apiVersion: node.k8s.io/v1 | ||
| kind: RuntimeClass | ||
| metadata: | ||
| name: wasmedge | ||
| handler: wasmedge | ||
| ``` | ||
| ## Testing | ||
| Apply the following manifest to run sample pod using wasmedge: | ||
| ```yaml | ||
| 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: | ||
| ```bash | ||
| $ kubectl get pods | ||
| NAME READY STATUS RESTARTS AGE | ||
| wasmedge-test 0/1 Completed 0 28s | ||
| ``` |
