How to Convert Kustomize to Helm Chart - Step by Step Guide

Step 1

Input Your Kustomize Configuration

Start with your existing Kustomize configuration. Whether you need to migrate to Helm, consolidate overlays, or create reusable charts:

•
Paste kustomization.yaml: Copy your Kustomize configuration file
•
Upload file: Select your kustomization.yaml from disk
•
Try sample: Click "Sample" to see example Kustomize config
Step 2

Automatic Helm Chart Generation

The converter automatically transforms your Kustomize configuration into a complete Helm chart:

•
Chart.yaml: Generated chart metadata with version and description
•
values.yaml: Extracted values from namePrefix, nameSuffix, commonLabels
•
templates/: Kubernetes manifests converted to Helm templates
•
_helpers.tpl: Standard Helm helper templates for labels and names
Step 3

Review Generated Files

Browse through the generated Helm chart files:

•
File selector: Switch between Chart.yaml, values.yaml, and templates
•
Preview output: See how Kustomize configs map to Helm values
•
Copy individual files: Copy specific files to clipboard
Step 4

Download and Deploy Your Helm Chart

Get your complete Helm chart ready for deployment:

•
Download ZIP: Get complete chart structure with all files
•
Extract and customize: Modify values.yaml for your environment
•
Install with Helm: Deploy using helm install command

Frequently Asked Questions

What is Kustomize and why migrate to Helm?

Kustomize is a Kubernetes-native configuration management tool. Migrating to Helm provides better versioning, templating capabilities, rollback support, and a larger ecosystem of charts for easier application lifecycle management.

Are the generated Helm charts production-ready?

Yes! The converter generates standard Helm chart structure following best practices. Review the generated values and templates to ensure they match your requirements, then test before deploying to production.

What Kustomize features are supported?

The converter supports namePrefix, nameSuffix, commonLabels, commonAnnotations, replicas, images, configMapGenerator, and secretGenerator. These are mapped to Helm values and templates for parameterization.

How do I use the generated Helm chart?

Download the ZIP, extract it, and run: helm install my-release ./myapp. Customize values.yaml for different environments and use helm upgrade for updates.

Is my Kustomize configuration secure during conversion?

Absolutely! All processing happens in your browser. Your Kustomize configurations never leave your computer or get sent to any server, making it completely safe for sensitive configurations.

Can I convert Kustomize overlays to Helm?

Yes! Kustomize overlays can be converted by pasting the kustomization.yaml file. The base configurations and patches will be merged and converted to Helm templates with extracted values for easy customization.
