After checking out the ource, build dora in docker and create an image:
docker build -t dora .
Next, create a data directory if it does not exist, and put config.yaml in it. This directory will be used to read the config and to store your leases database file.
mkdir data
touch data/config.yaml
(edit config.yaml)
Then run the image you created with --net=host and with the data dir volume mounted:
docker run -it --rm --init --net=host -v "$(pwd)/data":/var/lib/dora dora
