Location of Dockers images in all Operating Systems
The location of the images vary depending on the driver Docker is using for storage. Actually, Docker images are stored in two files as shown by following command.
# docker info
aufs – Most linux version
/var/lib/docker/aufs/diff/<id> has the file contents of the images.
/var/lib/docker/repositories-aufs is a JSON file containing local image information. This can be viewed with the command docker images.
btrfs
TBD
devicemapper (Redhat)
/var/lib/docker/devicemapper/devicemapper/data – stores the images
/var/lib/docker/devicemapper/devicemapper/metadata – the metadata
vfs
TBD
Mac OS X
~/VirtualBox VMs/boot2docker-vm
Mac OS X using boot2docker
/Users/rajesh.kumar/.docker/machine/machines/default
File Name – disk.vmdk
Windows:
%USERPROFILE%/VirtualBox VMs/boot2docker-vm
You can manually set the storage driver with the -s or –storage-driver= option to the Docker daemon.
/var/lib/docker/{driver-name} will contain the driver specific storage for contents of the images.
/var/lib/docker/graph/<id> now only contains metadata about the image, in the json and layersize files.
