How to Convert Docker Compose to Helm Chart - Complete Guide

Step 1

Input Your Docker Compose File

Start by providing your docker-compose.yml file. Whether you're packaging your application for Helm or migrating to Kubernetes:

•
Paste directly: Copy your docker-compose.yml content and paste it into the input editor
•
Upload file: Click "Upload" to select your compose file from your project directory
•
Try the sample: Click "Sample" to load a complete example with services, ports, and volumes
Step 2

Automatic Chart Generation

Our converter generates a complete, production-ready Helm chart structure from your Docker Compose configuration:

•
Chart.yaml: Generated with proper metadata, version, and app information
•
values.yaml: Extracted image, replicas, ports, environment variables, and resources
•
templates/: Deployment, Service, PVC templates with Helm template syntax
•
_helpers.tpl: Common Helm helper templates for names, labels, and selectors
Step 3

Review and Customize

Browse through the generated Helm chart files using the dropdown selector. Each file is ready to use:

•
File selector: Switch between Chart.yaml, values.yaml, and template files
•
Copy individual files: Copy any file content to your clipboard
•
Download complete chart: Get all files in a ZIP archive with proper folder structure
Step 4

Deploy with Helm

Deploy your application to Kubernetes using Helm:

•
Extract ZIP: Unzip the downloaded chart into your project directory
•
Install chart: Run helm install myapp ./myapp
•
Customize values: Edit values.yaml to customize deployment settings
•
Upgrade: Use helm upgrade myapp ./myapp to update

Frequently Asked Questions

Why convert Docker Compose to Helm charts?

Helm is the package manager for Kubernetes, providing versioning, rollback, and templating capabilities. Converting Docker Compose to Helm allows you to manage production Kubernetes deployments with proper release management, making it easy to upgrade, rollback, and customize deployments across different environments.

What's included in the generated Helm chart?

The converter generates a complete Helm chart structure: Chart.yaml with metadata, values.yaml with configurable parameters, templates/ folder with Deployment, Service, and PVC templates, and _helpers.tpl with common template functions. Everything follows Helm best practices.

Can I customize the generated chart?

Absolutely! The generated values.yaml contains all customizable parameters (image, replicas, resources, ports, etc.). You can edit these values or create multiple values files for different environments (values-dev.yaml, values-prod.yaml) and use them with helm install -f values-dev.yaml.

How do I deploy multiple services from Docker Compose?

Currently, the converter focuses on the first service in your compose file. For multi-service applications, you can either convert each service separately to create individual Helm charts, or manually combine them into a single chart with multiple deployments. This approach gives you better control over versioning and dependencies between services.

Is the generated chart production-ready?

The generated chart provides a solid foundation following Helm best practices. Review the templates, adjust resource limits, add health checks, configure ingress if needed, and test in a dev environment before production. The chart structure is ready for customization and extension based on your specific requirements.

Can I add the chart to a Helm repository?

Yes! After downloading and customizing the chart, you can package it with helm package myapp/ and publish it to a Helm repository (GitHub Pages, ChartMuseum, Harbor, etc.) for easy distribution and versioning across your organization.
