Big Bang Documentation

Big Bang is an umbrella Helm chart that uses Flux to deploy and reconcile a configurable collection of Kubernetes packages.

New to Big Bang? Follow the Getting Started path:

  1. Understand what Big Bang manages and what remains outside its boundary.
  2. Review the prerequisites for your selected release and configuration.
  3. Choose an installation path:
  4. Evaluation quickstart for a disposable development or demonstration cluster.
  5. First production-oriented deployment for a customer-managed GitOps environment.
  6. Disconnected deployment when dependencies must be mirrored inside the environment.
  7. Continue with configuration and operations before promoting a deployment to production.

The evaluation quickstart is not a production baseline. Big Bang also does not provision or harden the Kubernetes cluster on which it runs.

Sources of Truth

Documentation is versioned with the repository. When instructions disagree with generated or executable content for the selected release, use these sources in order:

  1. chart/Chart.yaml for the chart and Kubernetes version constraints.
  2. chart/values.yaml and the generated configuration reference for values and defaults.
  3. base/ and rendered manifests for Flux resources and Kubernetes objects.
  4. The selected release notes for required migrations and known changes.
