# docker-powerdns-admin
[PowerDNS-Admin](https://github.com/ngoduykhanh/PowerDNS-Admin) provides a dashboard for PowerDNS management.
[PowerDNS](https://www.powerdns.com/) 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.
The examples also packages:
- [aescanero/docker-powerdns-admin-alpine](https://github.com/aescanero/docker-powerdns-admin-alpine) based in [ngoduykhanh/PowerDNS-Admin](https://github.com/ngoduykhanh/PowerDNS-Admin) which provides a dashboard for PowerDNS management.
- [mariadb](https://www.mariadb.org) which is required for bootstrapping a MariaDB deployment for the database requirements of PowerDNS and PowerDNS-Admin applications.
## Docker image for powerdns-admin to manage powerdns
This is a Alpine based image to reduce size (is the small of the newest PowerDNS-Admin images) and let a faster deployment of lastest PowerDNS-Admin (https://github.com/ngoduykhanh/PowerDNS-Admin)
This image only runs with a Mysql database (see examples)
There are some enviroment variables needed to run the container:
* PDNS_API_KEY: Access key to PowerDNS API (needed)
* DOMAIN: Domain to manage (needed)
* LOCALPATH: Path in the host machine where the database is stored (needed)
* DB_NAME: Database to use in the MySql Server for PowerDNS (needed)
* DB_USERNAME: User with access to manage the MySql Database (needed)
* DB_USER_PASSWORD: Password of the MySql user (needed)
* DB_ROOT_PASSWORD: Password of the MySql user (needed)
## How to test this container with Docker Composer:
```
$ git clone https://github.com/aescanero/docker-powerdns-admin-alpine
$ cd docker-powerdns-admin-alpine
$ mkdir ~/mysql
$ LOCALPATH="~/mysql" DOMAIN="disasterproject.com" DB_USERNAME="powerdns" DB_USER_PASSWORD="password" DB_ROOT_PASSWORD="password" DB_NAME="powerdns" PDNS_API_KEY="random" docker-compose up -d
$ docker-compose ps
```
And then open http://WHERE_IS_RUNNING_DOCKER:9191 to access PowerDNS-Admin
To remove:
```
$ cd ~/docker-powerdns-admin-alpine
$ docker-compose stop
$ docker-compose rm
```
Database is in ~/mysql, you must remove it if you don't use it again.
## Test the container with Podman:
```
mkdir ~/mysql
export LOCALPATH=`pwd`"/mysql"
export DOMAIN="disasterproject.com"
export DB_USERNAME="powerdns"
export DB_USER_PASSWORD="password"
export DB_ROOT_PASSWORD="password"
export DB_NAME="powerdns"
export PDNS_API_KEY="random"
sudo podman run -d -v ${LOCALPATH}:/var/lib/mysql \
-e MYSQL_PASSWORD="${DB_USER_PASSWORD}" \
-e MYSQL_DATABASE="${DB_NAME}" \
-e MYSQL_USER="${DB_USERNAME}" \
-e MYSQL_ROOT_PASSWORD="${DB_ROOT_PASSWORD}" \
--ip 10.88.0.254 --name mysql yobasystems/alpine-mariadb
sudo podman run -d \

## Chart for Kubernetes deployment, (using at least Helm v3 beta3):
### Introduction
This chart bootstraps a [pschiffe/docker-pdns](https://github.com/pschiffe/docker-pdns) deployment on a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
It also packages:
- [aescanero/docker-powerdns-admin-alpine](https://github.com/aescanero/docker-powerdns-admin-alpine) based in [ngoduykhanh/PowerDNS-Admin](https://github.com/ngoduykhanh/PowerDNS-Admin) which provide a dashboard for PowerDNS management.
- [mariadb](https://www.mariadb.org) 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`:
```console
$ helm install --name my-release https://raw.githubusercontent.com/aescanero/helm-powerdns/master/test/powerdns.tgz
```
The command deploys PowerDNS on the Kubernetes cluster in the default configuration. The [configuration](#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:
```console
$ 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,
```console
$ helm install --name powerdns-release \
--set domain=disasterproject.com \
https://raw.githubusercontent.com/aescanero/helm-powerdns/master/test/powerdns.tgz
```
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,
```console
$ helm install --name my-release -f values.yaml https://raw.githubusercontent.com/aescanero/helm-powerdns/master/test/powerdns.tgz
```
## Persistence
The [mariadb](https://www.mariadb.org) image stores the Database at `/var/lib/mysql` path of the container.
Persistent Volume Claims are used to keep the data across deployments.
