Tutorial

Overview​

Holos is a configuration management tool for Kubernetes implementing the rendered manifests pattern. It handles configurations ranging from single resources to multi-cluster platforms across regions.

Key components:

  • Platform schemas defining component integration
  • Building blocks unifying Helm, Kustomize and Kubernetes configs with CUE
  • BuildPlan pipeline for generating, transforming and validating manifests

Video​

The video below offers a basic overview of Holos by walking you through the tooling gap at the Kubernetes integration layer and demonstrating how to integrate multiple Helm charts using data from CUE.

Holos' role in your organization​

Platform engineers use Holos to generate Kubernetes manifests, both locally and in CI pipelines. The manifests are committed to version control and deployed via GitOps tools like ArgoCD or Flux.

Holos integrates seamlessly with existing Helm charts, Kustomize bases, and other version-controlled configurations.

Advantages of Holos​

Safe​

Holos leverages CUE for strong typing and validation of configuration data, ensuring consistent output from Helm and other tools.

Consistent​

A unified pipeline processes all configurations - whether from CUE, Helm, or Kustomize - through the same well-defined stages.

Flexible​

Composable building blocks for generation, transformation, validation and integration let teams assemble workflows that match their needs.

The core is intentionally unopinionated about platform configuration patterns. Common needs like environments and clusters are provided as customizable topics recipes rather than enforced structures.
