Images
Operating System Images
The Cluster API driver for Magnum relies on specific OpenStack images containing all necessary dependencies for deploying Kubernetes clusters. These images are pre-configured with Kubernetes binaries, container runtimes, networking components, and other required software.
The images used by the Cluster API driver for Magnum are built using the
kubernetes-sigs/image-builder
project. This project provides a comprehensive and flexible framework for
constructing Kubernetes-specific images.
Building Images
In order to simplify the process of building images, the Cluster API driver for
Magnum provides a small Python utility which wraps the image-builder
project.
To build the images, run the following command:
$ pip install magnum-cluster-api
$ magnum-cluster-api-image-builder --version v1.26.2
In the example above, this command will build the images for Kubernetes version
v1.26.2
. The --version
flag is optional and defaults to v1.26.2
.
