# Cloudflare — Public IP
> Container to periodically update public IP address with a Cloudflare DNS record
### About
This project aims to provide a docker image that can be used to update an A record through Cloudflare's API. The value would be the external (public) IP address relative to the running container. Why would this be important? If you ever wanted to run a home-lab with a dynamic IP address, then this can be used to periodically ensure that said IP address is saved to a given Cloudflare A record.
