A simple program to update Cloudflare DNS records on start and on exit of the program. This solves the issue for users of Cloudflare that for example create a domain like: k8s-masters.example.com and add all nodes to it as a seperate A/AAAA record.

The configuration is done using environment variables:

CF_API_KEY="YOUR_CLOUDFLARE_API_KEY"
CF_API_EMAIL="YOUR_CLOUDFLARE_EMAIL"

DNS_NAMES="k8s-masters.example.com,k8s-workers.example.com"
IP_ADDRESS="1.1.1.1,1::"

See the file bundle.yaml in the repo root.
