HomeIP

This is a small alpine based nodejs container which will gather your public IP from a cloud service. This is used to update a DNS record via Hetzner DNS API to point to your public IP.

Platform: ARM

As this Docker Image is primary used on my Raspberries, the base image is arm32v7/node:lts-alpine3.10.

Docker

docker pull smhagit/homeip

This image is built with GitHub Actions via self-hosted runner on an arm64 Raspberry Pi.

Usage

Attention: This only works with Hetzner DNS API.
