# 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.
|
||||
|
||||
| Parameter | Description | Default |
|
||||
| ------------------------------- | ------------------------------- | ---------------------------------------------------------- |
|
||||
| `image.repository` | cloudflare-dyndns image | `hotio/cloudflare-ddns` |
|
||||
| `image.tag` | cloudflare-dyndns image tag | `latest` |
|
||||
| `image.pullPolicy` | cloudflare-dyndns image pull policy | `Always` |
|
||||
| `cloudflare.user` | The username of your Cloudflare account, should be your email address. | `` |
|
||||
| `cloudflare.token` | The token you generated in Cloudflare's API settings. | `` |
|
||||
| `cloudflare.zones` | The domain(s) you wish to update, separated by `;` | `` |
|
||||
| `cloudflare.hosts` | The subdomain(s) you wish to update, separated by `;` | `` |
|
||||
| `cloudflare.record_types` | The record types to update, separated by `;` | `` |
|
||||
| `cloudflare.detection_mode` | Source to query for public IP | `dig-google.com` |
|
||||
| `cloudflare.log_level` | Verbosity of the logs printed to stdout/stderr | `1` |
|
||||
| `cloudflare.sleep_interval` | Polling time in seconds | `300` |
|
||||
|
||||
|
||||
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.

You can connect to the container running cloudflare-dyndns. To open a shell session in the pod run the following:
|
||||
|
||||
- kubectl exec -i -t --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "cloudflare-dyndns.fullname" . }} -o jsonpath='{.items[0].metadata.name}') /bin/sh
|
||||
|
||||
To trail the logs for the cloudflare-dyndns pod run the following:
|
||||
|
||||
- kubectl logs -f --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "cloudflare-dyndns.fullname" . }} -o jsonpath='{ .items[0].metadata.name }')
