SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

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.

FAQPage Schema
How do I validate kustomization.yaml references to prevent Kubernetes deployment errors?

To validate kustomization.yaml references, you can check that all resource and patch files exist and are well-formed. This process detects missing references and malformed patches early to prevent runtime failures in your Kubernetes configurations.

What is the best way to find orphaned files in my kustomize Kubernetes directory?

Finding orphaned files in a kustomize directory involves identifying YAML files present in the folder that are not referenced in kustomization.yaml. This orphan file detection ensures every configuration file is actively managed and deployed.

How do I check cross-environment consistency for kustomize overlays?

Checking cross-environment consistency for kustomize overlays compares resource and patch lists across different environments for discrepancies. This comparison ensures configurations remain synchronized and consistent across your deployment targets.

Can I verify secretGenerator and configMapGenerator entries in kustomize?

Yes, you can verify secretGenerator and configMapGenerator entries in kustomize configurations. This validation checks generator definitions and optional settings like disableNameSuffixHash to ensure they are correctly configured before deployment.

Does kustomize build validation catch configuration issues in CI/CD pipelines?

Yes, kustomize build validation attempts to build the configuration with kustomize build to verify correctness. Running this in CI/CD pipelines catches configuration issues early, preventing deployment failures and ensuring reliability.
