Python script to update DNS A record of your domain dynamically using gandi.net LiveDNS API:
The script was developed for those behind a dynamic IP interface (e.g. home server/pi/nas).
The config-template.txt file should be renamed to config.txt, and modified with your gandi.net API key, domain name, and A-record (@, dev, home, pi, etc).
Every time the script runs, it will query an external service to retrieve the external IP of the machine, compare it to the current A record in the zone at gandi.net, and then update the record if the IP has changed.
Requirements:
pip install -r requirements.txt
You can then run the script as a cron job :
*/15 * * * * python /home/user/gandi_ddns.py
But to be nice to the API servers, you should choose a random offset for your job. For example to run at 2 minutes after the hour, and then every 15 minutes :
2-59/15 * * * * python /home/user/gandi-ddns.py
macOS
cd gandi-ddns
ln -s $(pwd) /usr/local/gandi-ddns
sudo cp gandi.ddns.plist /Library/LaunchDaemons/
sudo launchctl /Library/LaunchDaemons/gandi.ddns.plist
Docker
The docker container is published as rmarchant/gandi-ddns. To run,
pass it an argument pointing to the config file. The config file must be mounted into the container's filesystem.
docker run -it --rm -v /path/to/config/file.txt:/config.txt rmarchant/gandi-ddns /config.txt
If you're on Kubernetes, you can create a CronJob to run this periodically.
