UniClOGS Linux

UniClOGS Linux is a project that extends the rpi-image-gen tool to build images specifically for UniClOGS running on Raspberry Pi.

📖 Overview

This project contains a series of configs used to define the desired customizations for a "golden" UniClOGS Ground System OS image, which standardizes and simplifies the process of spinning up a UniClOGS Ground System.

It achieves this by leveraging the rpi-image-gen tool, which reads the config files in this project to produce the exact image assets specified, along with a software bill of materials (SBOM) file.

The configuration and scripts that provision the resulting image can be found in the uniclogs/ directory of this project, which is also made available for use inside the container (where the image build process occurs).

Getting Started

These instructions will walk you through the process of setting up this project on a development system.

Prerequisites

• Podman
• Podman Compose

NOTE: If you have a non-ARM CPU you will need

• qemu-user-static (binfmt)

Generating an Image

The preferred way to generate an image is to run the helper script found in the root directory of this project. Upon successful generation, the image and sbom assets will be found in the build/ directory.

./generate.sh

NOTE: You will be prompted for the build user's password, which is imagegen.

Manual Generation

To perform manual generation, you'll need access to the container directly. You can get a shell inside the container by running the following command:

podman compose run --build rpi_imagegen bash

If running on a non-ARM host, from within the container, run the following command to set binfmt_misc.

sudo mount binfmt_misc -t binfmt_misc /proc/sys/fs/binfmt_misc

Then build the image:

./build.sh -D ~/uniclogs -c uniclogs -o ~/uniclogs/uniclogs.options

This task will take a little time to complete.

Manually copying the Generated Image Files to Host

To copy the generated image and files from within the container onto the host system, run:

podman ps
podman cp <containerid>:/home/imagegen/rpi-image-gen/work/rpi_uniclogs/deploy /path/to/destination

podman ps will show you the container id. Make sure to replace <containerid> in the above command with the actual container id.
