# Dynamic DNS using Cloudflare's DNS Services

A script that pushes the public IP address of the running machine to Cloudflare's DNS API's. It requires an existing A record to update.

## TL;DR;

```console
$ helm repo add billimek https://billimek.com/billimek-charts/
$ helm install billimek/cloudflare-dyndns
```

## Introduction

This code is adopted from [this original repo](https://github.com/hotio/docker-cloudflare-ddns)

## Installing the Chart

To install the chart with the release name `my-release`:

```console
$ helm install --name my-release billimek/cloudflare-dyndns
```

## Uninstalling the Chart

To uninstall/delete the `my-release` deployment:

```console
$ helm delete my-release --purge
```

The command removes all the Kubernetes components associated with the chart and deletes the release.

## Configuration

The following tables lists the configurable parameters of the Sentry chart and their default values.

Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,

```console
helm install --name my-release \
  --set config.cloudflare.token=thisismyapikey \
    billimek/cloudflare-dyndns
```

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 billimek/cloudflare-dyndns
```

Read through the [values.yaml](https://github.com/billimek/billimek-charts/blob/master/cloudflare-dyndns/values.yaml) file. It has several commented out suggested values.
