Docker Toolbox Cleanup Disk Space

Using Docker Toolbox for Windows with Virtualbox, I have run the following commands to cleanup docker:

Containers

docker rm -v $(docker ps -a -q -f status=exited)

Images

docker rmi $(docker images -f "dangling=true" -q)

Volumes

docker volume rm $(docker volume ls -qf dangling=true)

However, it seems my disk is still being consumed by my built images? I have also run the following script for cleanup:

#!/bin/bash

# remove exited containers:
docker ps --filter status=dead --filter status=exited -aq | xargs -r docker rm -v

# remove unused images:
docker images --no-trunc | grep '<none>' | awk '{ print $3 }' | xargs -r docker rmi

# remove unused volumes:
find '/var/lib/docker/volumes/' -mindepth 1 -maxdepth 1 -type d | grep -vFf <(
  docker ps -aq | xargs docker inspect | jq -r '.[] | .Mounts | .[] | .Name | select(.)'
) | xargs -r rm -fr

I received the following error:

An error occurred trying to connect: Get http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/containers/json?all=1&filters=%7B%22status%22%3A%7B%22dead%22%3Atrue%2C%22exited%22%3Atrue%7D%7D: open //./pipe/docker_engine: The system cannot find the file specified.

I believe this is due to my use of Docker Toolbox on a non-Linux system. Therefore my path to unused volumes is off?

In what directory does Docker Toolbox store the images it creates?

You can also try some commands that were added to version 1.13.0:

$ docker system prune
$ docker container prune
$ docker image prune
$ docker volume prune
$ docker network prune

On Linux, my dockerclean script is this:

#!/bin/bash

# Remove dead containers
docker ps -f status=dead --format '{{ .ID }}' | xargs -r docker rm -v
# Remove dangling volumes
docker volume ls -qf dangling=true | xargs -r docker volume rm
# Remove untagged images
docker images --digests --format '{{.Repository}}:{{.Tag}}@{{.Digest}}' | sed -rne 's/([^>]):<none>@/\1@/p' | xargs -r docker rmi
# Remove dangling images
docker images -qf dangling=true | xargs -r docker rmi
# Remove temporary files
rm -f /var/lib/docker/tmp/*
