This repository provides a small script to update dyndns records for the hoster wint.glonbal. There is also a docker image running a cron job calling the script once every minute. The docker image can be found on docker hub.
The easiest way is to use the docker container. You can start the container by running the the following command. Replace userID, apiPassword and domain with the correct values for your account. The FAQ in your wint.global account contains an article on setting up dyndns.
docker run -d -e USER_ID='userID' -e API_KEY='apiPassword' -e DOMAIN='domain' --rm --name wint.global-dyndns panzki/wint.global-dyndns:latest
If you don't want to use the docker container you can run the script using Python 3.6+.
python refresh_dyndns.py -u userID -k apiPassword -d domain
