# UCI Docker Image Builder

A build script plus associated library to facilitate building docker linux images using any of three distros (alpine,debian,ubuntu) and either architecture (amd64/arm64) 

The Dockerfile is minimal, calling a set of distro specific scripts and common scripts in order to build the image

The build environment makes user of docker's  "buildx bake" commands and a docker-bake.hcl file

The master branch is configured to build base images from the docker hub distro base images

The main script is "build" At the very minimum run as just `./build` it will build an alpine image from the docker hub official alpine latest image with a minimal set of packages installed (e.g. git) and a custom uci shell environment.

The repo also supports (with scripts) pushing to alternate private repositories packages (like a self hosted gitea or github)

One can make decendent images in one of two way. 

1. Make your base images on the master branch then create a new branch and edit the script files in the src folder
3. User the installer script (./install) to install to link the build script into your system path.  Then clone the template branch


the build script requires an init.sh file in a source directory for the scripts it will run while building a new image
by default that is `<source directory>/init.sh`.  by default that source directory is `src/` relative to the current directory
