Build Status

Simple, Docker-based, light, network-boot Linux system, based on Alpine.

How it works

It uses Docker Alpine Linux images from multiarch to build a light rootfs, pack it into an initramfs, and provide a matching kernel.

How to use ?

Customize your image if needed:

  • edit the Dockerfile.template
  • edit init from assets/init/init
  • add services in assets/etc/services-parts

Build the initrd.img and extract vmlinuz:

# BOOTMAKER_ARCH=x86_64 ./build.sh

You'll get the files, ready to be distributed via pxe to network-boot your machines

Supported architectures

  • x86_64
  • armhf

more to come...

Cross Building

Add support for crossbuilding, then build your image normally:

apt-get install qemu-user-static
docker run --rm --privileged multiarch/qemu-user-static:register

Example pxelinux config

menuentry "Bootmaker image" {
  set root=(pxe)
  set gfxpayload=1024x768x16,1024x768
  echo "loading linux..."
  linux /boot/vmlinuz quiet ro nofb nomodeset console=tty0
  echo "loading initrd..."
  initrd /boot/initrd.img
  echo "booting..."
  boot
}
