capo-image-elements

This repository contains diskimage-builder elements for building images for Cluster API provider for OpenStack.

These images take a different approach than the upstream image-builder project in that they are built using diskimage-builder and not Packer.

These images were primarily built to be consumed by the Cluster API driver for Magnum, however, they will likely generate qcow2 images that should work directly with the Cluster API provider for OpenStack.

Releases

Automatic updates

This repository runs nightly updates to grab the latest maintained Kubernetes versions and creates a pull request to update the versions in the CI workflow.

Pre-release images

Upon every merge to the main branch, a new pre-release image will be built and published as a GitHub pre-release. In addition, contributors of this repository are able to trigger builds by using the workflow dispatch trigger.

Release images

Once a pre-release is created, a CI workflow will start up a DevStack instance with the Cluster API provider for OpenStack, spin up a cluster with this image and ensure that it can spin up a cluster successfully.

Building the images

To build the images, you will need to have diskimage-builder installed. You can install it using pip:

pip install diskimage-builder

Once you have diskimage-builder installed, you can build the images by exporting the ELEMENTS_PATH and running the following command:

export ELEMENTS_PATH=$PWD/elements
export DIB_RELEASE=jammy
export DIB_KUBERNETES_VERSION=1.34.0
disk-image-create vm ubuntu kubernetes

You can add any other elements that you require for your image by adding them to the command.
