Running HA in docker on a 8GB Pi 3B.
There is 4.2G in /var/lib/docker/overlay2
Any way to figure out why and if I can free space because I get this report from docker system df

not much danlging around either:
root@pi:/home/daz# docker image ls -f dangling=true
REPOSITORY TAG IMAGE ID CREATED SIZE
root@pi:/home/daz#
and in desperation:
root@pi:/home/daz# docker system prune
WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all dangling images
