README

Overview

Crossplane is an open source multicloud control plane. It introduces workload and resource abstractions on-top of existing managed services that enables a high degree of workload portability across cloud providers. A single crossplane enables the provisioning and full-lifecycle management of services and infrastructure across a wide range of providers, offerings, vendors, regions, and clusters. Crossplane offers a universal API for cloud computing, a workload scheduler, and a set of smart controllers that can automate work across clouds.

Crossplane presents a declarative management style API that covers a wide range of portable abstractions including databases, message queues, buckets, data pipelines, serverless, clusters, and many more coming. It’s based on the declarative resource model of the popular Kubernetes project, and applies many of the lessons learned in container orchestration to multicloud workload and resource orchestration.

Crossplane supports a clean separation of concerns between developers and administrators. Developers define workloads without having to worry about implementation details, environment constraints, and policies. Administrators can define environment specifics, and policies. The separation of concern leads to a higher degree of reusability and reduces complexity.

Crossplane includes a workload scheduler that can factor a number of criteria including capabilities, availability, reliability, cost, regions, and performance while deploying workloads and their resources. The scheduler works alongside specialized resource controllers to ensure policies set by administrators are honored.

Architecture and Vision

The full architecture and vision of the Crossplane project is described in depth in the architecture document. It is the best place to learn more about how Crossplane fits into the Kubernetes ecosystem, the intended use cases, and comparisons to existing projects.

Project Status

The project is an early preview. We realize that it's going to take a village to arrive at the vision of a multicloud control plane, and we wanted to open this up early to get your help and feedback. Please see the Roadmap for details on what we are planning for future releases, and the API Reference for the status of each Crossplane API group.

Official Releases

Official releases of Crossplane can be found on the releases page. Please note that it is strongly recommended that you use official releases of Crossplane, as unreleased versions from the master branch are subject to changes and incompatibilities that will not be supported in the official releases. Builds from the master branch can have functionality changed and even removed at any time without compatibility support and without prior notice.

Licensing

Crossplane is under the Apache 2.0 license.
