## Examples

Zone names are provided as examples. Think about adapting with the value of provider_zone in configuration file.

With minimum providers:

```
unbound:
  applicationservice: unbound
  provider_zone: externaldns
  zones_name:
    - localdns
  values:
    general.dns_resolver.unbound_default_forwards:
      - 9.9.9.9
```

With all providers:

```
unbound:
  applicationservice: unbound
  provider_zone: externaldns
  zones_name:
    - journald
    - externaldns
    - localdns
  values:
    general.dns_resolver.unbound_default_forwards:
      - 9.9.9.9
```
