⁠Docker-DuckDNS

Docker image to update DuckDNS⁠ dynamic domains, according to the HTTP API specifications⁠.

The image will request the DuckDNS HTTPS API endpoint in loop each X minutes, updating the IP associated with your domain/s with the IP that performed the request.

Main features:

• Based on alpine:latest
• Using curl as a non-root user
• Token can be provided using Docker Secrets

⁠Getting started

Supposing your domain is mydomain.duckdns.org:

docker run -d -e DOMAINS=mydomain.duckdns.org -e TOKEN=abcd1234 -e FREQUENCY=10 davidlor/duckdns

• DOMAINS: comma-separated list of your duckdns.org domains (required)
• TOKEN: your personal DuckDNS token (required or provide using Docker Secret)
• FREQUENCY: time to wait between requests, in minutes (default: 15)
