# Helm Chart for PowerDNS
* Installs a PowerDNS authoritative nameserver inside a Kubernetes cluster
## TL;DR;
```console
$ git clone https://github.com/cdwv/powerdns-helm
$ cd powerdns-helm
$ helm install .
```
> Note: This will leave you with a PowerDNS server deployed to your k8s cluster. You will also need to configure some means of accesibility from the outside world for the DNS server to be accesible. You can do it e.g. by modifying your nginx-ingress-controller.
## Installing the Chart
To install the chart with the release name `my-release`:
```console
$ helm install --name my-release .
```
## Uninstalling the Chart
To uninstall/delete the my-release deployment:
```console
$ helm delete my-release
```
The command removes all the Kubernetes components associated with the chart and deletes the release.

# Modifications to nginx-ingress
General steps are outlined below. You can consult the files in the nginx-ingress folder for more information.
1. Patch the nginx-ingress deployment to add UDP services (--udp-services-configmap=nginx-ingress/udp-ports)
2. Add udp-ports configmap to nginx-ingress namespace
2. Add a UDP loadbalancer service
