Install knative and WASMEdge on IBM Cloud

Create a cluster called knawd-k8s on IBM Cloud. For full instructions see https://cloud.ibm.com/docs/containers?topic=containers-getting-started
Install the IBM Cloud Cli. The instructions please ensure you install the https://cloud.ibm.com/docs/cli?topic=cli-getting-started
Install the kubernetes service plugin https://cloud.ibm.com/docs/cli?topic=cli-install-devtools-manually#idt-install-kube
Once the cluster is complete login with the ibmcloud cli
```
ibm cloud login
```

Now configure the kubectl connection

ibmcloud ks cluster config -c knawd-k8s

We are going to follow a summary of the instructions for the knative website.
Install the custom resource definitions which are the objects such as service that you will use to deploy an app.
```
kubectl apply -f https://github.com/knative/serving/releases/download/knative-v1.8.3/serving-crds.yaml
```

Then install the knative serving core

kubectl apply -f https://github.com/knative/serving/releases/download/knative-v1.8.3/serving-core.yaml

Now we install the networking layer

kubectl apply -f https://github.com/knative/net-kourier/releases/download/knative-v1.8.1/kourier.yaml

And Patch the knative space

kubectl patch configmap/config-network \
 --namespace knative-serving \
 --type merge \
 --patch '{"data":{"ingress-class":"kourier.ingress.networking.knative.dev"}}'

Finally configure dns

kubectl apply -f https://github.com/knative/serving/releases/download/knative-v1.8.3/serving-default-domain.yaml

Patch the knative service to allow for the crun runtime to be specified as an attribute in the service.

kubectl patch configmap/config-features -n knative-serving --type merge --patch '{"data":{"kubernetes.podspec-runtimeclassname":"enabled"}}'

Now run install the deployment project

git clone https://github.com/uirlis/wasi-crun-deployer
cd wasi-crun-deployer/charts/wasi-crun-deployer
helm install wasi-crun-deployer . --create-namespace --namespace knawd --set job.autoRestart=true

Finally run the tempate helloworld service.

git clone https://github.com/uirlis/helloworld-rust-wasi
cd helloworld-rust-wasi
kubectl apply -f service.yaml

Get the external IP of the kourier network

kubectl get svc kourier -n kourier-system

NAME      TYPE           CLUSTER-IP       EXTERNAL-IP      PORT(S)                      AGE
