Introduction

Kblocks is a framework for building Kubernetes custom resource operators using familiar infrastructure tools like Helm, Terraform, OpenTofu, CDK8s and Winglang.

How does it work?​

To create a new block, all you need is:

  1. Define the block API through a JSON Schema.
  2. Choose the backing engine (e.g. Helm, Terraform, OpenTofu, Winglang, etc.)
  3. Implement the block logic in the engine's language (e.g. Helm templates, Terraform config)
  4. Run kb build to create an operator that can be deployed to a Kubernetes cluster.
  5. Install the operator to your Kubernetes cluster through Helm.
  6. Done! Now your cluster has a new resource backed by Helm or Terraform.
