Helm Chart Scaffolding

Comprehensive guidance for creating, organizing, and managing Helm charts for packaging and deploying Kubernetes applications.

Purpose

This skill provides step-by-step instructions for building production-ready Helm charts, including chart structure, templating patterns, values management, and validation strategies.

When to Use This Skill

Use this skill when you need to:

• Create new Helm charts from scratch
• Package Kubernetes applications for distribution
• Manage multi-environment deployments with Helm
• Implement templating for reusable Kubernetes manifests
• Set up Helm chart repositories
• Follow Helm best practices and conventions

Detailed patterns and worked examples

Detailed pattern documentation lives in `references/details.md`. Read that file when the navigation tier above is insufficient.

Best Practices

1. **Use semantic versioning** for chart and app versions 2. **Document all values** in values.yaml with comments 3. **Use template helpers** for repeated logic 4. **Validate charts** before packaging 5. **Pin dependency versions** explicitly 6. **Use conditions** for optional resources 7. **Follow naming conventions** (lowercase, hyphens) 8. **Include NOTES.txt** with usage instructions 9. **Add labels** consistently using helpers 10. **Test installations** in all environments

Troubleshooting

**Template rendering errors:**

helm template my-app ./my-app --debug

**Dependency issues:**

helm dependency update
helm dependency list

**Installation failures:**

helm install my-app ./my-app --dry-run --debug
kubectl get events --sort-by='.lastTimestamp'
