install boot2docker to harddisk in the virtualbox

install_boot2docker_2_hadrdisk.txt

1, create a virtual machine from the virtualbox with VDI harddisk

2, add a virtual CDROM to the virtual machine and select boot2docker.iso ( the boot2docker.iso should be downloaded before)

3, start the virtual machine

4, write the boot2docker.iso image to the virtual harddisk using dd command

# dd if=/dev/cdrom of=/dev/sda

5, shutdown the virtual machine

6, remove the virtual CDROM

7, restart the virtual machine

8, use fdisk to create second partition from the VDI harddisk

# fdisk /dev/sda

select "n" to create second primary partition table from the sda and save the change

9, format the second partition using following command:


#mkfs.ext4 -L boot2docker-data /dev/sda2

10, reboot the boot2docker, now the second partition will be mounted to /mnt/sda2/var/lib/docker/aufs and then softlink to /var/lib/docker

all the docker image will be put under /var/lib/docker directory
