debian-image-builder

build Debian disk images (with Docker)

background

i want to build a standalone Debian image for Scuttlebutt pubs, which we can write to an SD card to boot local Arm Linux devices like the Raspberry Pi, as well as use as a bootable disk on a remote cloud platform.

i notice that every project that needs disk images has their own hand-rolled way to create disk images (e.g. Raspberry Pi project, BeagleBone project, etc). i also notice vmdb2 is a re-write of vmdebootstrap, which is the most common way to build images. so to support my own project, i combined some learnings into a standalone script that can be used in any project, hope it's useful to someone else! :)

example

with Docker installed:

git clone https://github.com/ahdinosaur/debian-image-builder
cd debian-image-builder
npm run example

see more example inputs in ./examples

install

npm install -g debian-image-builder

usage

Usage:
  debian-image-builder [options]

  Arguments:

    --input <path>: required directory of input image spec
    --output <path>: required directory to output build results
    --name <name>: optional name of image

  Flags:

    -h, --help: show this usage
    -d, --docker: build image using docker

  Examples:

    debian-image-builder --docker --input ./examples/simple --output ./output

if using --docker, you need Docker installed.

if not using --docker, you need the following packages installed:

• qemu-user-static
• qemu-utils
• dosfstools
• vmdb2
