WARNING: volumes have changed in Docker 1.7.0, if your're using Docker 1.7.0 (or up) and you downloaded the script before June 27th 2015 you should download an updated version of the script or docker pull martin/docker-cleanup-volumes an updated image. Older versions of the script will delete all your volumes on Docker 1.7.0.
Shellscript to delete orphaned docker volumes in /var/lib/docker/volumes and /var/lib/docker/vfs/dir
usage: sudo ./docker-cleanup-volumes.sh [--dry-run]
--dry-run : Use the --dry-run option to have the script print the volumes that would have been deleted without actually deleting them.
run the "latest" forward compatible Docker client version, currently 1.5.0 (available are 1.4.1, 1.5.0, 1.6.2 and 1.7.0)
docker run -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/docker:/var/lib/docker --rm martin/docker-cleanup-volumes --dry-run
or run a specific Docker client version, e.g. 1.4.1
docker run -v /var/run/docker.sock:/var/run/docker.sock -v /var/lib/docker:/var/lib/docker --rm martin/docker-cleanup-volumes:1.4.1 --dry-run
