Use dynamic ip with your domain – cloudflare-ddns

Well there is a static IP option always there but to all out there doesn’t want to pay an extra for it, you can set up and use your own domain or subdomain for this service.

We are gonna use a Docker image for small amd64/ARM Docker container that allows you to use CloudFlare as a DDNS / DynDNS Provider.

Offical Docker page is here

First you gonna need an API token from cloudflare.

To create a CloudFlare API token for your DNS zone go to https://dash.cloudflare.com/profile/api-tokens and follow these steps:

Click Create Token

Provide the token a name, for example, cloudflare-ddns

Grant the token the following permissions:

Zone – Zone Settings – Read

Zone – Zone – Read

Zone – DNS – Edit

Set the zone resources to:

Include – All zones

Complete the wizard and copy the generated token into the API_KEY variable for the container

Then you can use this docker compose file to start up your ddns service.

version: '2'
services:
 cloudflare-ddns:
    image: oznu/cloudflare-ddns
    restart: unless-stopped
    environment:
     - API_KEY=YOUR-API-KEY
     - ZONE=YOUR-DOMAIN
     - PROXIED=false
