Safeguard against FritzBox losing internet connectivity. The container checks daily at 02:00 if api.ipify.org returns a valid public IP. If this is not the case, it will reboot the FritzBox to attempt to restore the connection.
Note: This project is mostly to play around with docker images on the DSM, a simple cron job would work just as well.
Work in progress: Set up automatic build pipeline.
Upload these files to DSM into /volume2/docker/_build:
- Dockerfile
- fritzboxmonitor.sh
Then, ssh to /volume2/docker/_build and run:
docker build . -t chrismkv/fritzboxmonitorThe image fritzboxmonitor will be created.
On the Syno, register ghcr.io as repository (Only needed once, can't use the GUI in Container Manager):
export CR_PAT=(MyPAT)
echo $CR_PAT | docker login ghcr.io -u ChrisMKV --password-stdin
Image is now automatically built and published to ghcr.io with Github Action. The package appears on: https://github.com/ChrisMKV?tab=packages
By adding LABEL org.opencontainers.image.source https://github.com/ChrisMKV/fritzboxmonitor into the Dockerfile the package is automatically linked to the repo.
The image can now be manually pulled from the repo with docker pull ghcr.io/chrismkv/fritzboxmonitor:latest or automatically with the updated compose file.
Use the docker-compose.yml file as a template for the DSM Docker Project. Update FritzBox details as required, then deploy the project.
