cloudflare-client VS docker-cloudflare-ddns

% docker run --entrypoint /bin/sh -it oznu/cloudflare-ddns:latest -c "curl -vvI https://api.cloudflare.com/user/tokens/verify" | grep -A 8 "Server certificate" * Server certificate: * subject: C=US; ST=California; L=San Francisco; O=Cloudflare, Inc.; CN=api.cloudflare.com * start date: May 19 00:00:00 2022 GMT * expire date: May 19 23:59:59 2023 GMT * subjectAltName: host "api.cloudflare.com" matched cert's "api.cloudflare.com" * issuer: C=US; O=Cloudflare, Inc.; CN=Cloudflare Inc ECC CA-3 * SSL certificate verify ok. * Using HTTP2, server supports multi-use * Connection state changed (HTTP/2 confirmed)

this might workhttps://api.cloudflare.com/ based on what I found here https://community.cloudflare.com/t/create-a-subdomain-on-cloudflare-automatically/357063/2

I've just built a small fetch-based, zero-dependency JavaScript library for Cloudflare API that works in Node.js, Deno, and CF Workers environment — https://github.com/kriasoft/cloudflare-client

https://github.com/oznu/docker-cloudflare-ddns has been archived and perhaps one should avoid it. You will not receive any updates in the future.

That container was last built Mar 21 2020. Looks like this is the source code.

I've seen the cloudflare-ddns solutions on github here and here but it doesn't look like it'd work for my intended use case. Do you know any software that can be selfhosted that allows for that?

Something like CloudFlare ddns docker container will check your external IP every minute or so and automatically update if required

I hate noip. They spam my email and I have to remember to confirm my domain every month or it gets deleted. I just switched to this with cloudflare and its so much better.

Cloudflare DDNS

I've used this in the past: https://hub.docker.com/r/oznu/cloudflare-ddns/

Cloudflare is a nice option.
