How do I move / update where all docker images and data goes to

[meyay (Metin Y.)]

This should do the trick:

Specify disk used by Overlay2 driver

Either mount your desired drive in whatever docker info | grep Root returns (should be var/lib/docker) or modify /etc/docker/deamon.json and set data-root to whetever you like, e.g.: { "data-root": "/mount/point/of/your/drive" }
