UCI Docker Image Builder
Prerequistes:
see https://hacking.kebler.net/Linux/Arch/docker/
A build script plus associated library to facilitate building docker linux images using any of four distros (arch,alpine,debian,ubuntu) and either architecture (amd64/arm64)
The Dockerfile is minimal copying a directory and then calling a packages script and and init script in two RUN statements 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.
To run the ./build script from other repos install it using the install script
'./install
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 ways.
- Make your base images on the master branch (or a branch if you need to customize)
- User the installer script (./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
run
./build -h
