I´m trying to set an additional nameserver for a deployment on gcloud Kubernetes like this:

```
  dnsConfig:
    nameservers:
    - 172.16.248.32
    searches:
    - ns1.svc.cluster.local
    - mynetwork.local
    options:
    - name: ndots
      value: "2"
    - name: edns0

```

This fails with the following error:

> 
> spec.template.spec.dnsConfig: Forbidden: DNSConfig: custom pod DNS is
>  disabled by feature gate
> 
> 
> 

How can I fix this?
