Project Summary

Managing KRM configuration at scale

Project Description

kpt is a package-centric toolchain that enables a WYSIWYG configuration authoring, automation, and delivery experience, which simplifies managing Kubernetes platforms and KRM-driven infrastructure at scale by manipulating declarative Configuration as Data.

Why CNCF?

The basic building blocks for kpt are in place and we want to encourage further adoption and contributions to the project. Having the project in the CNCF also makes it easier for users to contribute to the project as the CNCF CLA is widely accepted in the industry.

Benefit to the Landscape

Kpt is an implementation of the Configuration as Data paradigm and thereby provides a novel approach for managing declarative configuration at scale. Since kpt uses the Kubernetes Resource Model as the data format throughout the lifecycle of configuration, it obviously integrates well with Kubernetes, but also has the potential for simplifying the use of many other tools in the CNCF landscape.

Cloud Native 'Fit'

kpt is built using cloud native technologies and fits within the “App Definition & Image Build” area.

Cloud Native 'Integration'

kpt simplifies management of KRM configuration, thereby making it easier for users to use Kubernetes at scale, and provides a set of building blocks for building custom platforms with cloud native technologies. As a result of kpt using KRM as the fundamental data format, it can help manage any tool that can be configured with KRM.

The kpt CLI and its server-side implementation as Porch (both in the repos in this application) are also utilized by other open source projects such as Nephio (https://nephio.org/) as an underlying platform for configuration management.

Cloud Native Overlap

kpt is an implementation of the Configuration as Data paradigm, so it uses an approach that is different from other tools currently in the Cloud Native landscape. It does however solve similar challenges for users as existing products in the CNCF like Kustomize and Helm.

Similar projects

Kustomize: Similar to kpt, kustomize has support for customization of KRM resources via a transformation-based approach. But while Kustomize builds the final configuration out-of-place primarily using the overlay-pattern, kpt is optimized for WYSIWYG configuration and in-place customization.

Helm: While Helm leverages templating for customization of KRM resources, kpt uses a transformation-based approach that keeps the configuration in KRM format all the way from authoring to deployment.

Product or Service to Project separation

kpt is used within some Google Cloud Platform services, but the open source project roadmap and direction is driven by the needs of the community. This will continue to be true in the future.
