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

1) edit file /var/lib/boot2docker/profile, and add the proxy setting lines to the file

export HTTP_PROXY=http://<proxy host>:<port>
export HTTPS_PROXY=https://<proxy host>:<port>

2) restart the docker

/etc/init.d/docker restart

If the coreos is deployed behind a proxy, we can simply use following steps to make docker work:

1) copy the /usr/lib/systemd/system/docker.service to /etc/systemd/system/ directory

sudo cp /usr/lib/systemd/system/docker.service /etc/systemd/system/

2) edit the /etc/systemd/system/docker.service file and add 

Environment="HTTP_PROXY=http://proxy.example.com:8080"
