kustomize-resource-validation

What problem does it solve?

This Skill automates the validation of kustomization.yaml files, detecting missing references, malformed patches, and orphaned files to prevent deployment errors.

Core Features & Use Cases

• Reference Verification: Checks that all resource and patch references exist and are well-formed.
• Orphan File Detection: Identifies YAML files in the directory that are not referenced.
• Cross-Environment Consistency: Compares resource and patch lists across different overlays or environments for discrepancies.
• Build Validation: Attempts to build the kustomize configuration with kustomize build to verify correctness.
• Generator Checks: Validates secretGenerator and configMapGenerator entries and optional settings like disableNameSuffixHash.
• Use Case: Prevents runtime failures in CI/CD pipelines by catching configuration issues early.

Quick Start

Run the validation on the kustomization.yaml file in your current directory to verify your Kubernetes configurations for issues.
