A toolkit to help you manage, manipulate, customize, and apply Kubernetes resource configuration.

Visit Website →

Overview

Kpt is a Git-native tool for managing Kubernetes configurations. It allows you to fetch, modify, and apply configurations from a Git repository. A key concept in Kpt is the use of 'functions' - containerized programs that read, transform, and write configuration files. This provides a powerful and reusable way to apply cross-cutting modifications to your Kubernetes YAML.

✨ Key Features

  • Git-native workflow for configuration management
  • Packaging of configurations using Kpt packages
  • Configuration transformation using functions (in containers)
  • Declarative and imperative application of resources
  • Integration with Kustomize

🎯 Key Differentiators

  • Configuration-as-data approach
  • Use of containerized functions for transformations
  • Strong integration with Git for versioning and updates

Unique Value: Treats Kubernetes configuration as data that can be programmatically manipulated through a pipeline of versioned, reusable functions, enabling scalable and maintainable configuration management.

🎯 Use Cases (4)

Managing Kubernetes configuration at scale Creating reusable configuration transformations (e.g., adding a sidecar) Automating configuration validation and linting Distributing and customizing base configurations

✅ Best For

  • Used within Google for managing internal Kubernetes configurations.

💡 Check With Vendor

Verify these considerations match your specific requirements:

  • Simple application deployments
  • Users who prefer a template-based approach like Helm

🏆 Alternatives

Kustomize Helm Carvel ytt

Unlike Kustomize's static overlays, Kpt functions can perform complex, programmatic transformations. Compared to Helm's string templating, Kpt operates on structured YAML data, which is safer and more powerful.
