This project contains a simple python script for downloading and customizing Ubuntu ISO files. This is useful for generating custom ISO images with Ubuntu Autoinstall YAML baked-in.
To get started using this script, first clone the repository, or simply download the build_iso.py script.
This tool requires additional Python modules to function. Use the included requirements.txt to install the required modules.
You can do this in a Python virtual environment if you want to keep your system clean.
# (optional) Create a virtual environment for python
python3 -m venv my_virtual_environment
# (optional) Activate the virtual environment
source ./my_virtual_environment/bin/activate
# Install the required modules from requirements.txt
pip install -r ./requirements.txt
The most basic usage of this script will simply download the requested ISO image.
./build_iso.py -v 22.04.4
By default, the live-server ISO is assumed. However, you can change the type, version and architecture to download.
./build_iso.py -v 23.10 --type desktop --architecture arm64
To customize the ISO image, you need to provide a custom grub.cfg and/or a directory to import.
./build_iso.py -v 24.04 --type desktop --import-dir ./custom/autoinstall --grub-menu ./grub.cfg
This is useful for configuring autoinstall deployments. See Ubuntu Autoinstall for more information.
The script is self-documented. Simply run ./build_iso.py --help to get an overview of what arguments are available.
