Where does Docker keep images/containers so i can better track my disk usage

I’ve seen several janitor container that cleanup periodically.

As I a build stuff, run compose, etc I run several commands to clean up…

 # remove untagged images  
 docker rmi $(docker images | grep none | awk '{ print $3}')
 # remove unused volumes  
 docker volume rm $(docker volume ls -q )  
 # `shotgun` remove unused networks
 docker network rm $(docker network ls | grep "_default")   
 # remove stopped + exited containers, I skip Exit 0 as I have old scripts using data containers.
 docker rm -v $(docker ps -a | grep "Exit [1-255]" | awk '{ print $1 }')
