¯\_(ツ)_/¯

Heya,

After Windows 10 got 2004 update, I finally was able to use Docker for Windows with enabled and working VirtualBox.

By default Docker for Windows will keep its data on C: drive and if you have small SSD drive supposed to use only for system, Docker can consume all free space.

Lets move this to new location.

Here is what we need to do:

Stop Docker and make sure it has STOPPED state for two services

wsl --list -v

you should see something like this

  NAME                   STATE           VERSION
* docker-desktop         Stopped         2
  docker-desktop-data    Stopped         2

Create a directory where Docker will store all its data

mkdir -p D:\Docker\wsl\data

Export Docker Data

wsl --export docker-desktop-data "D:\Docker\wsl\data\docker-desktop-data.tar"

This could take a while. In my case it was about 6Gb tarred and took about 1 minute :)

Now, unregister docker-desktop-data from WSL2

wsl --unregister docker-desktop-data

Run again wsl --list -v and you’d see only docker-desktop registered in WSL.

Lets import that back and bind to our new location

wsl --import docker-desktop-data "D:\Docker\wsl\data" "D:\Docker\wsl\data\docker-desktop-data.tar" --version 2

Now, just start Docker for Windows and see that all works :)

Happy windockering!
