This solved my disk space problem. The named volumes default to /var/lib/docker, but other volumes, particularly host volumes, will be located in the directory you specify. For that I need to attach a volume to it in order to store the data. Finally, I start the container again. In the docs I could only find how to attach the volume, not how to set its size.
