By default, it allocates all data in /var/lib/docker. You should start the
container pointing it somewhere else, or you will end up filling up

By default storage is ephemeral. You start a docker container, do work, shut it
down and the work is lost. You use either the docker run --mount or --volume
options to map host storage to where the container needs persistent storage.
These days you'd be running some orchestration tool

other mechanisms of which you speak. The --ip and --hostname options take care
of the network configuration. I would be interested in what the anti-VOLUMEites

That is why VOLUME is there so that your persistent or customized data is
not part of the image.
