# realDynDNS
|
|
RealDynDNS aims to be a replacement to "classical" dynDNS solutions that offer a subdomain. Instead realDynDns actually changes your DNS entries.
|
|
|
|
This service requires your DNS provider to expose an API that allows your DNS entries to be changed.
|
|
A service that provides your current external IP is also required.
|
|
|
|
## Configuration
|
|
The configuration is done via a YAML file called `config.yaml`. The following example shows the configuration for a domain with two subdomains.
|
|
|
|
Configuration of the IP provider and the DNS provider is mandatory.
|
|
|
|
The `check_interval` is mandatory and follows the cron syntax including seconds. It defines how often the IP is checked and the DNS entries are updated. If you don't own the external ip provider, please be nice and don't set the interval too low.
|
|
|
|
You may configure multiple top level domains with multiple subdomains. If you also want the top level domain to be updated, add it to the subdomains list with an `@`.
|
|
|
|
```yaml
|
|
ip_provider:
|
|
type: plain
|
|
config:
|
|
url: https://ifconfig.me
|
|
dns_provider:
|
|
type: ionos
|
|
config:
|
|
api_key: <your-api-key>
|
|
base_url: https://api.hosting.ionos.com/dns
|
|
notification_provider:
|
|
type: gotify
|
|
config:
|
|
url: <your-gotify-host>
|
|
token: <your-token>
|
|
priority: 0
|
|
domains:
|
|
- tld: example.com
|
|
subdomains:
|
|
- "@"
|
|
- www
|
|
check_interval: 0 0 0/6 * * * *
|
|
```
|
|
|
|
The config file is expected to be in the same directory as the binary and called `config.yaml`. For the OCR image, the root directory is `/app`.
|
|
|
|
## DNS Providers
|
|
The DNS provider abstracts the API of your DNS provider. Currently the following providers are supported:
|
|
|
|
### IONOS
|
|
IONOS requires two configuration parameters. You can get your API key [here](https://developer.hosting.ionos.com/docs/getstarted).
|
|
```yaml
|
|
api_key: <your-api-key>
|
|
base_url: https://api.hosting.ionos.com/dns
|
|
```
|
|
|
|
## External IP Providers
|
|
The external IP provider is used to get your current external IP. Currently the following providers are supported:
|
|
|
|
### Plain
|
|
Any provider that returns your IP as plain text can be used. The following configuration is required:
|
|
```yaml
|
|
url: <your-providers-URL>
|
|
```
|
|
|
|
Examples for providers are:
|
|
- https://ifconfig.me
|
|
- https://api.ipify.org
|
|
|
|
## Notification Providers
|
|
The notification provider is used to send notifications whena IP address changes and a DNS record is updated.
|
|
|
|
### Console
|
|
The console notification provider is used to print the notification to the console. This is the default notification provider.
|
|
|
|
### Gotify
|
|
The Gotify notification provider is used to send notifications to a Gotify server.
|
|
|
|
```yaml
|
|
url: <your-gotify-host>
|
|
token: <your-token>
|
|
priority: 0
|
|
```
|
|
|
|
The priority must be between 0 and 4. |
