Frequently Asked Questions

What is a Helm chart?
A Helm chart is a package of pre-configured Kubernetes resources. It contains templates, default values, and metadata that let you install complex applications with a single command like 'helm install'.
Should I use Helm or Kustomize?
Use Helm when you need templating, versioned releases, and a package distribution model. Use Kustomize for simpler overlay-based customization without templates. Many teams use both: Helm for third-party apps, Kustomize for internal services.
How do I create my own Helm chart?
Run 'helm create my-chart' to scaffold a chart structure. Customize the templates in the templates/ directory, set defaults in values.yaml, and test with 'helm template' and 'helm install --dry-run'.
