Image Builder

Please see our Book for more in-depth documentation.

The Image Builder is a collection of cross-provider Kubernetes virtual machine image building utilities.

There are currently 3 distinct tools in this repo:

Each project is independent from each other, with the goal of eventually merging into a single tool.

The konfigadm directory contains manifests for use with the konfigadm CLI.

Participation in the Kubernetes community is governed by the Kubernetes Code of Conduct.

To build images for Kubernetes-conformant clusters in a consistent way across infrastructures, providers, and business needs.
- To install all software, containers, and configuration needed by downstream tools such as Cluster API providers, to enable them to pass conformance tests
- Support end users requirements to customize images for their business needs.
To provide assurances in the binaries and configuration in images for purposes of security auditing and operational stability.
- Allow introspection of artifacts, software versions, and configurations in a given image.
- Support repeatable build processes where the same inputs of requested install versions result in the same installed binaries.
To ensure that the creation of images is performed via well defined phases. Where users could choose specific phases that they needed.

To provide upgrade or downgrade semantics.
To provide guarantees that the software installed provides a fully functional system.
To prescribe the hardware architecture of the build system.
