## gandi-livedns

The purpose of this container is to update DNS zone records using Gandi's LiveDNS (http://doc.livedns.gandi.net/) with your WAN IP.

This image is extremely lightweight  (Alpine Linux based) and has very few dependencies. The actual DNS update program is coded in shell script only.

### Configuration

Mandatory variables:

* APIKEY: your Gandi API key
* DOMAIN: your Gandi domain
* RECORD_LIST: DNS records to update separated by ";"

Optional variables:

* REFRESH_INTERVAL: Delay between updates (default: 10mn)
* TTL: Set Time To Live for records (default: 300)
* SET_IPV4: Update A record (default: yes)
* SET_IPV6: Update AAAA record (default: no)
* FORCE_IPV4: Force the IPv4 address to be used in DNS A records
* FORCE_IPV6: Force the IPv6 address to be used in DNS AAAA records

### Examples

The easiest way to run gandi-livedns is simply to *docker run* it from a computer in your network, leaving it running in the background with all the default settings.

```shell
docker run -d \
	-e "APIKEY=<YOUR_VERY_SECRET_API_KEY>" \
	-e "RECORD_LIST=blog;www;@" \
	-e "DOMAIN=your-gandi-hosted-domain.com" \
	jbbodart/gandi-livedns
```

This will update **blog.your-gandi-hosted-domain.com**, **www.your-gandi-hosted-domain.com**, and **your-gandi-hosted-domain.com** with your internet-facing IP (IPv4) every 10 minutes

An equivalent setup using docker-compose could look like this:  

**docker-compose.yml**

```yml
version: '3.7'
...
    services:
    ...
        dyndns:
            image: jbbodart/gandi-livedns
            restart: unless-stopped
            env_file:
                - "dyndns.env"
```

**dyndns.env**

```properties
APIKEY=<YOUR_VERY_SECRET_API_KEY>
RECORD_LIST=blog;www;@
DOMAIN=your-gandi-hosted-domain.com
```
