What is YAML to Helm Chart Generator?

This tool converts raw Kubernetes YAML manifests into a complete Helm chart structure. It parses your Deployment YAML, extracts configurable values like image, replicas, ports, environment variables, and resource limits, then generates Chart.yaml, values.yaml with extracted defaults, and template files with Go template directives ({{ .Values.* }}).

How to Use

Paste your Kubernetes Deployment YAML manifest into the input area
Click "Generate" to convert the YAML into a Helm chart structure
Review the generated Chart.yaml, values.yaml, and template files
Copy the output and create the corresponding files in your Helm chart directory

Why Use This Tool?

Automatically extracts configurable values from raw Kubernetes YAML

Generates complete Helm chart structure with proper Go template directives

Handles environment variables, secrets, resource limits, and container ports

Creates _helpers.tpl with standard Helm naming conventions

Saves hours of manual conversion work when migrating to Helm

Tips & Best Practices

Review the generated values.yaml and adjust defaults for your environment
Add more templates like ingress.yaml or hpa.yaml as needed
Use helm lint to validate the generated chart before deploying
Consider adding a values-dev.yaml and values-prod.yaml for environment-specific overrides

Frequently Asked Questions

What types of Kubernetes resources are supported?

Currently, the tool focuses on Deployment resources with container specs. It extracts image, replicas, ports, environment variables (including secrets), and resource limits. Service templates are also generated based on the container ports.

How are secrets handled in the generated chart?

Environment variables that reference Kubernetes secrets (valueFrom.secretKeyRef) are extracted into values.yaml with secretName and secretKey references, and the template uses the corresponding Go template directives.

Can I customize the generated Helm chart?

Yes, the generated chart is a starting point. You can modify values.yaml to add or change defaults, and extend the templates with additional Kubernetes resources like Ingress, HPA, or ConfigMaps.

Does this tool send my YAML to a server?

No, all processing happens entirely in your browser. Your Kubernetes manifests never leave your device.

What if my YAML has multiple containers?

The tool processes the first container definition. For multi-container pods, you may need to manually adjust the generated templates to include additional containers.
