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.
