levels representing a child dependency, use the following command:

```bash
istioctl manifest generate -o istio_manifests
```

Use depth first search to traverse the created directory hierarchy when applying your YAML files. This is needed for
correct sequencing of dependencies. Child manifest directories must wait for their parent directory to be fully applied,
