generating-helm-charts_skill

Overview

This skill generates production-ready Helm charts for Kubernetes applications. It produces Chart.yaml, values.yaml, templates, helpers, and optional NOTES and README files tailored for multi-environment deployments. Use it to accelerate repeatable, best-practice chart creation and to validate charts before publishing.

How this skill works

The skill collects application requirements (image, replicas, ports, resources, ingress and config needs) and scaffolds a Chart directory with metadata, default values, and template files. It inserts reusable helper functions, sensible resource defaults, health probes and security contexts, and produces lintable output that works with helm lint and helm template. It also suggests testing and dependency steps for publishing.

When to use it

• Creating a new Helm chart for an application or microservice
• Converting an existing Kubernetes manifest into a reusable chart
• Preparing charts for multi-environment deployments (dev/stage/prod)
• Scaffolding charts with CI/CD-friendly values and templating
• Rapidly iterating chart structure before publishing to a chart repo

Best practices

• Include sensible defaults in values.yaml and keep environment-specific overrides external
• Add _helpers.tpl for common labels, name templates, and image helpers to reduce repetition
• Define resource requests/limits, securityContext, and readiness/liveness probes for production readiness
• Use helm lint and helm template to validate syntactic and rendering issues locally
• Version Chart.yaml properly (apiVersion v2 for Helm 3+) and document configuration in README

Example use cases

• Generate a chart for a web app with Deployment, Service, Ingress, and ConfigMap templates
• Produce separate values files for dev, staging, and production with differing replica and resource settings
• Convert raw kubernetes YAML manifests into a tidy chart with helpers and notes for operators
• Create charts that integrate dependent charts via charts/ and Chart.yaml dependencies
• Validate and lint charts in CI using helm template and helm lint before publishing
