Docker

Image size is 1.86GB.

docker pull ghcr.io/gaarv/kadenze-dl:latest

Pass options to command line:

docker run --rm \
    -v /absolute/local/path/to/download:/app/download \
    ghcr.io/gaarv/kadenze-dl kadenze-dl \
    --login "[email protected]" \
    --password "mypassword" \
    --download-path /app/download

Here, /absolute/local/path/to/download is where you want to do download videos on your system. Other paths defined in the command line as /app/download do not need changes as they refer to the Docker internal path.

You may also use a Configuration file:

docker run --rm \
    -v /absolute/local/path/to/download:/app/download \
    -v /absolute/local/path/to/configuration.yml:/app/configuration.yml \
    ghcr.io/gaarv/kadenze-dl kadenze-dl \
    --config-file /app/configuration.yml

In this setup, the download path defined in the configuration file must match the Docker internal path /app/download

List all available options with:

docker run --rm ghcr.io/gaarv/kadenze-dl kadenze-dl --help
