Change Docker machine location - Windows

Question

I am using docker toolbox on Windows 7 to run docker. (docker version 1.9.1)

As it turns out, the docker machine creates its VM at C:\\Users\\username\\.docker\\mach

Answer 1

Simply use the VirtualBox graphic interface to relocate the file disk.vmdk:

1. Copy file C:\Users\{myUsername}\.docker\machine\machines\default\disk.vmdk into another folder, say F:\docker-image\.
2. Open VirtualBox, select default VM and open Settings.
3. Open Storage, select current disk.vmdk and release it (or delete it).
4. Click on Choose Virtual Hard Disk File... and search for copied file in F:\docker-image\
5. A Warning occurs: VirtualBox complains of old VM UID then go to menu File, select Virtual Media Manager... and release or remove old disk.vmdk
6. Retry 4., it's done!
7. If required by your environment then do the relocation also for boot2docker.iso, Snapshot Folder, Video Capture.
