SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires PyYAML, and includes scripts (resource) and references (resource) and assets (resource) components.

What problem does it solve?

Helm chart validation and analysis helps teams catch structural, syntax, and security issues early, preventing failed deployments and downtime.

Core Features & Use Cases

  • Validation and linting of Helm charts to surface schema, syntax, and best-practice violations.
  • Template rendering and CRD documentation lookup to surface issues and ensure CRD docs availability.
  • Security checks on rendered manifests (securityContext, resources, image tags, and probes) to enforce Kubernetes best practices.
  • Ideal for CI pipelines, pre-release validation, and debugging chart problems in development and staging.

Quick Start

Run the skill against a chart: helm-validator ./charts/mychart

Frequently Asked Questions about helm-validator

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I lint and validate Helm charts for security and syntax issues?▼

Validate Helm charts by running checks against chart directories to surface schema, syntax, and best-practice violations alongside security checks on rendered manifests for missing securityContext and resource limits.

Can I check rendered Kubernetes manifests for missing securityContext and resource limits?▼

Yes, you can analyze rendered Kubernetes manifests to detect missing securityContext, resource limits, non-latest image tags, and improper health probes to enforce security best practices.

How do I run Helm chart validation in a CI/CD pipeline?▼

Integrate Helm chart validation into CI pipelines by executing checks against chart directories to catch structural, syntax, and security issues early, preventing failed deployments and downtime.

Does Helm chart validation work with Custom Resource Definitions and template rendering?▼

Yes, Helm validation supports template rendering and CRD documentation lookup to surface manifest issues and ensure Custom Resource Definition documentation availability during development.

Do I need PyYAML installed to validate and lint Helm charts?▼

Yes, PyYAML is a required dependency for parsing and validating YAML manifests when running checks to surface schema, syntax, and best-practice violations across your Helm charts.

Why should I use Helm chart linting instead of waiting for deployment errors?▼

Helm chart linting catches structural, syntax, and security issues early in the development lifecycle, preventing failed Kubernetes deployments and reducing downtime before reaching staging.
