Docker error : no space left on device

Question

I installed docker on a Debian 7 machine in the following way

$ echo deb http://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list
$          


        

Answer 1

Docker leaves dangling images around that can take up your space. To clean up after Docker, run the following:

docker image prune [-af if you want to force remove all images]

or with older versions of Docker:

docker rm $(docker ps -q -f 'status=exited')
docker rmi $(docker images -q -f "dangling=true")

This will remove exited and dangling images, which hopefully clears out device space.
