kustomize-validator

What problem does it solve?

It prevents broken Kubernetes deployments by finding Kustomize structure issues, render failures, schema errors, patch problems, and common security misconfigurations before you apply manifests.

Core Features & Use Cases

• Kustomize structure validation: Checks every kustomization.yaml for required fields and deprecated keys, and verifies referenced files exist.
• Overlay rendering + YAML sanity: Builds overlays with kustomize (or kubectl kustomize) and validates the rendered output with yamllint (with a yq fallback).
• Schema + consistency + security checks: Runs kubeconform for rendered-manifest validation, verifies patch targets and collision risks, and evaluates a security checklist for Pod/Deployment templates.

Quick Start

Ask the AI to validate your overlays by running read-only Kustomize rendering, schema validation, and a security checklist across all environments in your overlays directory.
