This document discusses the boot2docker-cli tool, which allows users to run Docker containers within a VirtualBox virtual machine. It downloads the boot2docker ISO image, creates a VirtualBox VM, and sets up networking to allow the VM and containers to access the internet and map container ports securely. The document provides an overview of common boot2docker-cli commands like init, up, ssh, save, down and delete. It also discusses the source code structure and build process.

2. boot2docker-cli features
VirutalBox Management Tool
This tool downloads the boot2docker ISO image, creates
a VirtualBox virtual machine, sets up two networks for
that virtual machine (one NAT to allow the VM and containers
to access the internet, the other host-only to allow container
port mapping to work securely), and then provides the user a
simple way to login via SSH.
