Powerdns Helm Save
Helm chart for PowerDNS deployment to kubernetes
Helm Chart for PowerDNS
- Installs a PowerDNS authoritative nameserver inside a Kubernetes cluster
TL;DR;
$ 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:
$ helm install --name my-release .
Uninstalling the Chart
To uninstall/delete the my-release deployment:
$ helm delete my-release
The command removes all the Kubernetes components associated with the chart and deletes the release.
