Change .docker directory on Windows

Question

The standard path on Windows where Docker places stuff:

C:\Users\<USER>\.docker 

We need to specify here:

 D:\Docker 

We could not find information on where and how to change this parameter. Any hint appreciated, thanks!

Answer 1

One solution that works for us is to create a symbolic link:

 mklink /J "C:\Users\<USER>\.docker" "D:\Docker" 

But this is not what we call a pure solution.

(All credit to the question, and this answer goes IMM0rtalis .)

Answer 2

You can simply define the HOME environment variable before starting a new boot2docker or docker machine .

 set HOME=D:\docker 

(add it to user environment variables if you want to keep it in CMD sessions)

These tools will look for any configuration in $HOME/.xxx
