gandynamic

A dirty script to push a DNS record pointing to your dynamic IPv4 IP, using Gandi's LiveDNS service.

Usable as a K8s job.

This is based on this script, with some refinements.

A full rewrite to a proper language is planned.

K8s cronjonb example

Push your Gandi API key in a K8s secret

kubectl create secret generic gandynamic --from-literal="API_KEY=<YOUR_GANDI_APIKEY>"
