## Deployment
## Deployment the wasm function into Kubernetes

> To setup `WasmEdge` workload runtime in kubernetes cluster and push images to a container registry,
> please refer to the [prerequisites](../../getting-started/Quickstarts/prerequisites) section for more info.

1. Create function

```shell
kubectl apply -f wasmedge-http-server.yaml
```

2. Check the function status

```shell
kubectl get functions.core.openfunction.io -w
NAME BUILDSTATE SERVINGSTATE BUILDER SERVING ADDRESS AGE
wasmedge-http-server Succeeded Running builder-4p2qq serving-lrd8c http://wasmedge-http-server.default.svc.cluster.local/echo 12m
```

3. Access function

Once the `BUILDSTATE` becomes `Succeeded` and the `SERVINGSTATE` becomes `Running`, you can access this function through the address in the `ADDRESS` field:
You can observe the process of a function with the following command:

```shell
kubectl run curl --image=radial/busyboxplus:curl -i --tty
curl http://wasmedge-http-server.default.svc.cluster.local/echo -X POST -d "WasmEdge"
WasmEdge
```
You can refer [this](https://openfunction.dev/docs/concepts/wasmedge_integration/#build-and-run-wasm-functions) guide on how to deploy this wasm function into Kubernetes.
