To run both versions of the helloworld service, use the following command:

```bash
kubectl apply -f helloworld.yaml
```

Alternatively, you can run just one version at a time by first defining the service:

```bash
kubectl apply -f helloworld.yaml -l service=helloworld
```

and then deploying version v1, v2, or both:

```bash
kubectl apply -f helloworld.yaml -l version=v1

        then:

        result.output.contains("Expected exception")

Also make sure you are running two versions (v1 and v2) of the helloworld service:

```bash
kubectl apply -f ../helloworld.yaml
```

## Configure the helloworld gateway

Apply the helloworld gateway configuration:

```bash
kubectl apply -f ./helloworld-gateway.yaml
```
