Dockerized LG webOS dev-mode renewal script

Renew LG webOS Developer Mode

This script is a modified version of the automatic renew script generated by Device/DevMode Manager for webOS TV.

Retrieve key

Use Device/Devmode Manager to generate the auto-renewal script. It contains the private key needed to renew the dev mode. Take the key and save it to a file, for example webos_privkey.key.

Build Docker image

Build the Docker image by executing docker build -t renew-dev-mode ..

If you intend to use this on a Synology DiskStation, you can now save the image as a tarball, with docker image save renew-dev-mode -o renew-dev-mode.tar. This lets you import the image into DSM's Docker GUI. You can then add a scheduled task in the DSM settings to execute docker start renew-dev-mode --attach every day (you might need to run the container as root.)

Run Docker container

Make sure to mount the directory containing the key file as /config (or change the PRIV_KEY_FILE.) You must at least set the DEVICE_HOST and DEVICE_PASSPHRASE variables according to the values shown by your TV.

docker run --mount type=bind,source="$(pwd)",target=/config --env DEVICE_HOST=192.168.x.x --env DEVICE_PASSPHRASE="passphrase" renew-dev-mode
