How do I create a docker machine with a specific URL using docker-machine and VirtualBox?

Question

I can create a Docker instance with the VirtualBox driver, but I cannot figure out how to specify the URL.

Create Command:

docker-machi

Pending the resolution of issue 1709, I use the following script (a Windows one, to be adapted for mac).

dmvbf.bat:

@echo off
setlocal enabledelayedexpansion
set machine=%1
if "%machine%" == "" (
    echo dmvbf expects a machine name
    exit /b 1
)
set ipx=%2
if "%ipx%" == "" (
    echo dmvbf x missing ^(for 192.168.x.y^)
    exit /b 2
)
set ipy=%3
if "%ipy%" == "" (
    echo dmvbf y missing ^(for 192.168.x.y^)
    exit /b 3
)

echo kill $(more /var/run/udhcpc.eth1.pid) | docker-machine ssh %machine% sudo tee /var/lib/boot2docker/bootsync.sh >NUL
echo ifconfig eth1 192.168.%ipx%.%ipy% netmask 255.255.255.0 broadcast 192.168.%ipx%.255 up | docker-machine ssh %machine% sudo tee -a /var/lib/boot2docker/bootsync.sh >NUL

docker-machine ssh %machine% "sudo cat /var/run/udhcpc.eth1.pid | xargs sudo kill"

docker-machine ssh %machine% "sudo ifconfig eth1 192.168.%ipx%.%ipy% netmask 255.255.255.0 broadcast 192.168.%ipx%.255 up"

I start the vm (docker-machine start ), and then:

dmvbf  99 101

I do that only once.

At the next docker-machine start , the IP will be 192.168.99.101.
