Where is the install location of the Windows Boot2Docker Image?

Question

I have proxy issues when creating a new docker machine on a Windows 10 Enterprise with the docker Toolbox installed:

docker-machine create -d hyperv mymachine

The following error message appears(formatted for better readablilty):

(mymachine) Unable to get the latest Boot2Docker ISO release version:

Get https://api.github.com/repos/boot2docker/boot2docker/releases/latest: dial tcp 192.30.253.116:443:

connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

I downloaded the Boot2Docker.iso Image from https://github.com/boot2docker/boot2docker/releases.

Now i just Need to copy it to the correct Folder in Windows.

Where do i need to copy the .iso image so that docker machine will find it?

After some experimenting with copying the iso file to following folders it worked (still got errors that it could not get latest version):

- C:\Program Files (x86)\Boot2Docker
- C:\Program Files\Boot2Docker
- C:\Users\user_name\.docker\machine
- C:\Users\user_name\.docker\machine\cache\

Following happened:

From the Output of docker machine:

(mymachine) Copying C:\Users\user_name\.docker\machine\cache\boot2docker.iso to C:\Users\user_name\.docker\machine\machines\jit-dev\boot2docker.iso

I conclude that the correct install location of the Boot2Docker.iso Image is under: C:\Users\user_name\.docker\machine\cache\boot2docker.iso

Side note: that the machines are separated by user name on Windows. Having the machine installed on one user does not mean it is available for others.
