This small Alpine Linux based Docker image will allow you to use the free CloudFlare DNS Service as a Dynamic DNS Provider (DDNS).
Default values are tuned to work with CapRover.
To create a CloudFlare API token for your DNS zone go to https://dash.cloudflare.com/profile/api-tokens and follow these steps:
1 - Click Create Token
2 - Provide the token a name, for example, cloudflare-ddns
3 - Grant the token the following permissions:
Zone - Zone Settings - Read
Zone - Zone - Read
Zone - DNS - Edit
4 - Set the zone resources to:
Include - All zones
5 - Complete the wizard and copy the generated token into the Cloudflare API token field
end: >-
Cloudflare DDNS has been successfully deployed.
