## Что такое "Dependency Injection" (инъекция зависимости)

We can create our helloworld app, using the custom config, with:

```bash
kubectl apply -f example-app.yaml
```

If you don't have [automatic sidecar injection](https://istio.io/docs/setup/additional-setup/sidecar-injection/#automatic-sidecar-injection)
set in your cluster you will need to manually inject it to the services instead:

```bash
istioctl kube-inject -f example-app.yaml -o example-app-istio.yaml
