Docker images/containers taking up space despite clean up

I noticed that Docker appears to be using a large amount of disk space. I can see the directory /Users/me/.docker/machine/machines/default is 27.4GB

I recently cleaned up all of the images and containers I wasn't using. Now, when I run docker ps I see that no images are running.

~ $ docker ps

I can also see that I have 2 containers available.

~ $ docker ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                     PORTS               NAMES
42332s42d3        cds-abm        "/bin/bash"         2 weeks ago         Exited (130) 2 weeks ago                       evil_shockley
9ssd64ee41        tes-abm        "/bin/bash"         2 weeks ago         Exited (130) 2 weeks ago                       lonely_brattain

I can then see I have 3 images.

~ $ docker images
REPOSITORY            TAG                 IMAGE ID            CREATED             SIZE
ghr/get  latest              6708fffdd4dfa        2 weeks ago         2.428 GB
<none>                <none>              96c5974ddse18        2 weeks ago         2.428 GB
fdbh/ere         latest              bf1da53766b1        2 weeks ago         2.225 GB

How can these be taking up nearly 30GB?

It is because you are not removing the volumes created by the containers when you stop the container. In the future, use -v when you remove the containers.

docker rm -v <container-id>

Regrading cleaning up the space, you have to ssh into docker-machine and remove all volumes created. To do so,

docker-machine ssh default
sudo -i # You may not get permission to enter in to volumes directory
cd /var/lib/docker/volumes
rm -rf *

Make sure none of your containers are currently running. Also, make sure that you don't need any of these volumes for later use (like DB containers).
