helm-chart-builder

What This Skill Does

The Helm Chart Builder is an opinionated, production-grade development assistant designed to streamline the creation, maintenance, and auditing of Kubernetes Helm charts. Rather than generating generic templates, this skill applies industry best practices to ensure your charts are secure, modular, and reusable. It handles everything from complex template logic in _helpers.tpl to implementing advanced Kubernetes security objects like NetworkPolicies and PodDisruptionBudgets.

Key features include automatic scaffolding of production-ready structures, intelligent auditing of existing templates for anti-patterns, and security hardening to ensure your deployments follow the principle of least privilege. It helps developers move from ad-hoc manifests to professional-grade infrastructure-as-code.

Installation

To install the Helm Chart Builder, use the OpenClaw CLI: clawhub install openclaw/skills/skills/alirezarezvani/helm-chart-builder

Use Cases

This skill is perfect for DevOps engineers and developers who need to:

• Rapidly scaffold new microservices with standard deployment, ingress, and service configurations.
• Audit existing charts to ensure they pass linting and security standards.
• Define complex configuration schemas for values.yaml using JSON Schema validation.
• Manage subchart dependencies for modular application stacks.
• Configure robust testing suites including connectivity checks and pre-upgrade hooks.

Example Prompts

1. "I need a production-ready Helm chart for a Go microservice that includes an HPA, PodDisruptionBudget, and a default NetworkPolicy."
2. "Review my current chart in the ./charts folder and identify any hardcoded values that should be moved to values.yaml or helper templates."
3. "Help me design a values.yaml schema that enforces strict type checking for my ingress hostnames and memory limits."

Tips & Limitations

• Tip: Always run /helm:security before submitting a Pull Request for your Helm chart to catch common misconfigurations like running as root or missing resource limits.
• Tip: Use the library chart pattern when sharing common configurations across multiple internal services to reduce duplication.
• Limitation: This tool is designed to work best with standard Kubernetes resource types. While it can handle custom resources (CRDs), it may require manual input for specific API version definitions.
• Limitation: While the skill provides security audits, it does not replace a comprehensive cluster-level policy engine like OPA Gatekeeper or Kyverno.
