Vercel Dynamic DNS

Vercel (formerly Zeit) offer a domains service backed by their own nameservers and API. Similarly to a domain managed via Cloudflare, it is relatively simple to set up a domain you own that can act as a dynamic DNS.

The program here is a small daemon you can run standalone or as a docker container in order to manage a subdomain for a domain you own.

It is run via environment variables of which there are three

VERCEL_API_KEY = Your API key from Vercel, you can get this here.

DOMAIN = The domain, as a string, that you are looking to change the records for (eg. example.com)

SUBDOMAIN = The name you are looking to dynamically update with the program's host IP as a string (eg. dynamic.)
