    Resize boot2docker VirtualBox image

Steps we will take:

Change boot2docker image type (this will take long)
Resize image
Resize partion (using GParted)

Stop boot2docker

boot2docker stop

Change the size of the image.

# Convert the VMDK image to VDI (one that we can resize). This will take some time.
vboxmanage clonehd ~/VirtualBox\ VMs/boot2docker-vm/boot2docker-vm.vmdk ~/VirtualBox\ VMs/boot2docker-vm/boot2docker-vm.vdi --format VDI --variant Standard

Resize

vboxmanage modifyhd ~/VirtualBox\ VMs/boot2docker-vm/boot2docker-vm.vdi --resize 40000

Next we need to change the boot2docker partition size to use our resized image
Install GParted on your boot2docker vm:


Download GParted ISO from http://gparted.sourceforge.net or http://sourceforge.net/projects/gparted/files/gparted-live-stable/0.18.0-2/
(Note that the latest version doesn't work, you need to use v0.18.0-2)
Open VirtualBox
Go to: boot2docker-vm > Settings > Storage
Right click - Add an IDE controller
Add your downloaded GParted ISO as CD/DVD
(boot2docker itself also is an ISO, do NOT remove it)
Add your VDI to the SATA controller as Harddisk
Remove the VMDK partition

Start GParted


Boot your boot2docker vm (it should boot from the GParted ISO/CD)
Choose all defaults

Resize the partition (in the GUI):


Right click > Resize on the boot2docker-data partition
Drag the slider to increase the partition/volume
Click Resize/Move
Click Apply > and one last time :) (this wont take long)
Quit and Shutdown

Next remove GParted


Go to: VirtualBox > boot2docker-vm > Settings > Storage
Remove the IDE controller (and thus the GParted ISO)

Start the boot2docker vm using VirtualBox


Click Start :)

After this you can start boot2docker normally
boot2docker status # => poweroff
boot2docker start
