Change .docker directory on Windows

Question

The standard path on Windows where Docker puts stuff is:

C:\Users\<USER>\.docker

We need to put it here:

D:\Docker

We couldn't find any info about where or how to change that setting. Any hint appreciated, thanks!

Answer 1

One solution that works for us is creating a symbolic link:

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

But it's not what we call a clean solution.

Answer 2

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

set HOME=D:\docker

(Add it to your user environment variables if you want it to persists across CMD sessions)

Those tools will look for any config in $HOME/.xxx
