Powerdns
PowerDNS with Mariadb and PowerDNS-Admin Helm to easy PowerDNS deploy on Kubernetes
PowerDNS is an open source DNS Authoritative Server (answer questions about domains it knows about, but will not go out on the net to resolve queries about other domains) software.
TL;DR;
Supported for Helm v3
helm repo add aecharts https://raw.githubusercontent.com/aescanero/helm-charts/master/
helm repo update
helm install aecharts/powerdns
Introduction
This chart bootstraps a pschiffe/docker-pdns deployment on a Kubernetes cluster using the Helm package manager.
It also packages:
- aescanero/docker-powerdns-admin-alpine based in ngoduykhanh/PowerDNS-Admin which provide a dashboard for PowerDNS management.
- mariadb which is required for bootstrapping a MariaDB deployment for the database requirements of PowerDNS and PowerDNS-Admin applications.
Prerequisites
- Kubernetes 1.8+ with Beta APIs enabled
- PV provisioner support in the underlying infrastructure (Optional)
Installing the Chart
To install the chart with the release name my-release:
helm repo add aecharts https://raw.githubusercontent.com/aescanero/helm-charts/master/
helm repo update
helm install my-release aecharts/powerdns
The command deploys PowerDNS on the Kubernetes cluster in the default configuration. The configuration section lists the parameters that can be configured during installation.
Tip: List all releases using
helm list
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.

The above parameters map to the env variables defined in each container. For more information please refer to each image documentation.
Specify each parameter using the --set key=value[,key=value] argument to helm install. For example,
helm repo add aecharts https://raw.githubusercontent.com/aescanero/helm-charts/master/
helm repo update
helm install powerdns-release --set domain=disasterproject.com aecharts/powerdns
The above command sets the domain managed by PowerDNS to disasterproject.com.
Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
helm repo add aecharts https://raw.githubusercontent.com/aescanero/helm-charts/master/
helm repo update
helm install powerdns-release -f values.yaml aecharts/powerdns
Persistence
The mariadb image stores the Database at /var/lib/mysql path of the container.
Persistent Volume Claims are used to keep the data across deployments.
