netzfisch/rpi-dyndns repository overview

⁠Dynamic DNS updater for the ARM based Raspberry PI.

Get youself a account at spDYN⁠ or similar provider. If you choose a different provider - make sure to read the **Customising section.

This images target the ARM architecture, uses the well known ddclient⁠ library and is based on alpine Linux⁠, and thus leads to a slimmer image.

Find the source code at GitHub⁠ or the ready-to-run image in the DockerHub⁠ and do not forget to star the repository ;-)

⁠Runing

Get ready to roll and run the container:

$ docker run --detach \
             --name ddclient \
             --restart unless-stopped \
             -e HOSTNAME=netzfisch.spdns.de \
             -e UPDATE_TOKEN=imwg-futl-mzmw \
             netzfisch/rpi-dyndns

⁠Configuring

Than setup the ddclient by reading the credentials from the environment variables and storing them in the running container:

$ docker exec ddclient setup

⁠Customising

To customise change ddclient.conf to your needs, e.g. see following configuration options at https://github.com/ddclient/ddclient/blob/master/sample-etc_ddclient.conf⁠.

Than build for yourself:

$ docker build -t netzfisch/rpi-dyndns:custom .

⁠Debugging

Check that the environment includes your credentials:

$ docker exec -it ddclient env

After running docker exec ddclient setup look up, if configuration was set right:

$ docker exec ddclient cat /etc/ddclient/ddclient.conf

Finally you could dig into the container:

$ docker exec -it ddclient ash
