Simple script to update DNS A record of your domain dynamically using gandi.net's API

Inspired from https://github.com/matt1/gandi-ddns

The script simply connects to Gandi LiveDNS API to update a specific A record from the current public IP Address. The script use ipify to get current IP Address, if the address is different from the one in the selected A record, the record is updated with the current IP Address.

You'll need a GANDI API Key to use the script. You can create one in the Security section of your Gandi Account.

git clone https://github.com/z720/gandi-ddns .
cd gandi-ddns
npm install
export GANDI_API_KEY=<your API Key>
npm start <yourdomain.example> <subdomain>

Using Environment Variables

docker run -e "GANDI_API_KEY=<your API Key>" -d z720/gandi-ddns <yourdomain.example> <subdomain>

It's possible to update the configuration by creating a config.json file in the script directory.

• api_key: Your API key if you want to store it in a file (probaby unsecure)
• endpoint (default https://dns.api.gandi.net/api/v5) The GANDI liveDNS endpoint if you need to overwrite it
• ipcheck (default https://api.ipify.org) The current public IP reference if you need to overwrite it (should return the IP address in plain text).
• domain: The domain to get the zone file from
• record: The record name to fetch, the record must exists and be an A record. The script only updates an existing records. Should probably work fine with @ record as well as *.subdomain.
• interval: (default 300 every 5 minutes) Time in minutes between each checks, for each check the script gets the record and the current IP Address.
• debug: Enable debugging - false by default.

• Only one record is updated, it means that only one subdomain/domain is updated. You can use a CNAME records to match the updated records or run several instance of the script at once.
