Boot2Docker For Linux

Boot2Docker is a free, open source, lightweight and minimalist distribution of Linux built around the famous Docker platform that allows developers to build, package and run any application, anywhere. It is derived from the Tiny Core Linux operating system.

It is powered by a Linux kernel from the 3.16 series, patched with AUFS (AnotherUnionFS), the latest stable release of Docker, using libcontainer, as well as support for SSH keys and container persistence through disk automount.

The Boot2Docker Linux distribution is available for download for free on Softpedia, distributed as a dual-arch Live CD ISO image that has only 20MB in size and is capable of booting the operating system on 64-bit (x86_64) or 32-bit (x86) computers.

Once downloaded, the ISO image must be burn onto a blank CD disc using any CD/DVD burning software or written on a USB flash drive using the UNetbootin or GNOME Disks utilities, transforming them into bootable medium, which will be later used to boot the operating system from the BIOS of your computer.

The live system will automatically boot when inserting the USB key or CD disc on your computer, but you will be able to press the F2, F3 or F4 keys on your keyboard to view available boot options, allowing advanced Linux users to pass extra parameters to the kernel, in case they have special hardware components.

Once the boot process finished, you will be dropped to a shell prompt, automatically logged in as root (system administrator). From there, you can start to use Docker, as well as various other command-line utilities that have been pre-installed in the distribution. Detailed information about how to use the distribution are available on the project’s GitHub page.
