SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Render Kubernetes manifests (Helm, Kustomize, raw YAML) and diff against a live cluster or previous render, flagging risky changes. Use when you need to preview what will change before applying.

Core Features & Use Cases

  • Diff manifests against a live cluster or git renders to surface drift
  • Supports Helm templates, Kustomize manifests, and plain YAML
  • Detects risk patterns like deprecated APIs, resource drift, and potential rollout issues
  • Use Case: Compare a Helm release against the currently deployed state to validate upgrades before apply.

Quick Start

Provide a path to your manifests and run the k8s-diff skill to see a diff against the live cluster or previous render.

FAQPage Schema
How do I diff Kubernetes manifests against a live cluster before deploying?▼

You can diff Kubernetes manifests against a live cluster by rendering Helm, Kustomize, or raw YAML and comparing the output to the current cluster state to surface drift and deployment risks.

Can I compare Helm templates against the currently deployed state to validate upgrades?▼

Yes, you can compare a Helm release against the currently deployed state to validate upgrades before applying changes to the Kubernetes cluster.

Does k8s-diff work with Kustomize and plain YAML workflows?▼

Yes, k8s-diff works with Kustomize manifests, Helm templates, and plain YAML workflows to render manifests and compare them against live clusters or previous git renders.

Do I need kubectl installed to run Kubernetes manifest diffs?▼

Yes, kubectl is a required prerequisite to run Kubernetes manifest diffs, while helm and kustomize are optional tools needed only if your specific workflow uses those rendering engines.

What risky changes can a Kubernetes manifest diff detect before applying?▼

A Kubernetes manifest diff can detect risk patterns like deprecated APIs, resource drift against the live cluster, and potential rollout issues before you apply changes.

Can I use Kubernetes manifest diffing in CI contexts to compare git history?▼

Yes, you can use Kubernetes manifest diffing in CI contexts to compare current renders against previous git history or live clusters to prevent risky deployments.
