Cloudflare DDNS Script

Docker DDNS Cloudflare (arm32v7 for Raspberry PI 3B+)

This container is an adapted version of this script. It runs once every minute and only makes requests if the IP has changed since last time. The IP is resolved by https://canihazip.com.

Quickstart 🚀

1. Get your api token here (Top right -> My Profile -> Scroll Down -> Global Api Key)

2. Create the wanted DNS record (e.g. some.example.com). The script can only update it, now create it.

3. Create an .env file:

EMAIL=[e-mail]
KEY=my_api_key
ZONE=example.org
DNS_RECORD=some.example.org

4. Run the container

docker run -d --name ddns --restart always --env-file .env ivantorgov/ddns-cloudflare-arm32v7

To check logs:

docker logs ddns

With docker-compose:
