docker-duckdns-minimalistic

Minimalistic docker image for dynamic DNS provided e.g. by duckdns.org

Brief

The goal of this repository is to create minimalistic docker image for updating DNS records of duckdns.org. The Dockerfile is based on busybox without any other dependencies, so the result image should be about the same size as the busybox image (much smaller than e.g. alpine).

Usage

Start container

docker run -d --name duckdns --restart unless-stopped \
	-e DUCKDNS_URL='https://www.duckdns.org/update?domains=exampledomain&token=a7c4d0ad-114e-40ef-ba1d-d217904a50f2' \
	-e DUCKDNS_INTERVAL=300 \
	-e DUCKDNS_TIMEOUT=10 \
	midlan6/duckdns-minimalistic

Put your's duckdns url to DUCKDNS_URL variable. Verbose version is also supported.

Variables DUCKDNS_INTERVAL and DUCKDNS_TIMEOUT are optional. Default values are same as shown in example above.

Logs

This docker image uses standard docker logging. To view the logs use:

docker logs <container>
