Where are Docker images stored on the host machine

Question

I managed to find the containers under directory /var/lib/docker/containers, but I can't find the images.

What are the directories and files under /var/lib/docker?

Answer 1

Actually, Docker images are stored in two files as shown by following command

$ docker info

Data file: /var/lib/docker/devicemapper/devicemapper/data

Metadata file: /var/lib/docker/devicemapper/devicemapper/metadata

Answer 2

If you are using Docker for MAC (not boot2docker) then the location is /Users/<</>UserName></>/Library/Containers/com.docker.docker/Data/

Answer 3

I use the boot2docker for Docker on Mac OSX, so the images is stored into the /Users/<USERNAME>/VirtualBox VMs/boot2docker-vm/boot2docker-vm.vmdk.

Answer 4

Expanding on Tristan's answer, in Windows with Hyper-V you can move the image with these steps from matthuisman:

In Windows 10,

1. Stop docker etc
2. Type "Hyper-V Manager" in task-bar search box and run it.
3. Select your PC in the left hand pane (Mine is called DESKTOP-CBP**)
4. Right click on the correct virtual machine (Mine is called MobyLinuxVM)
5. Select "Turn off" (If it is running)
6. Right click on it again and select "Move"
7. Follow the prompts

Answer 5

In Docker for Windows (native Windows) the default container storage is at:

   > docker info
   ...
   Docker Root Dir: C:\ProgramData\Docker
   ...

Answer 6

On the newly released 'Docker for Windows', which uses Hyper-V, data is located in the Docker virtual hard disk:

C:\Users\Public\Documents\Hyper-V\Virtual hard disks\MobyLinuxVM.vhdx

You can also open the 'Hyper-V Manager' for access to the Docker / MobyLinuxVM.
