Why should I use JMESPath instead of standard Kyverno patterns?

Use JMESPath when your logic requires conditionals, transformations, or cross-field validation that simple pattern matching cannot express.

Can this skill help enforce container resource limits?

Yes, it provides specific patterns for filtering containers without memory or CPU limits and implementing denial logic based on those results.

How do I test my JMESPath expressions before deploying?

This skill recommends using the 'kyverno jp' CLI tool to test queries against your local manifests to ensure syntax accuracy and avoid silent failures.

Does this skill support array transformations?

Absolutely. It excels at filtering arrays, extracting specific fields from multiple objects, and calculating lengths for validation checks.

デプロイメントとDevOps

Simplifies the creation and validation of complex Kyverno policies using production-tested JMESPath patterns for Kubernetes.

概要

This skill empowers developers to go beyond basic pattern matching in Kyverno by mastering JMESPath for advanced Kubernetes policy enforcement. It provides specialized guidance for querying nested resource data, implementing complex conditional logic, and performing cross-field validations that standard Kyverno patterns cannot handle. By integrating CLI testing best practices and production-ready implementation patterns, it ensures your policies are both powerful and safe to deploy in production environments.
