Crossplane is the open source multicloud control plane. With Crossplane you can manage your applications and infrastructure across clouds, regions, and clusters. Crossplane is composable and Kubernetes native. Deploy it to an existing Kubernetes cluster to manage cloud infrastructure like databases, buckets, and caches using kubectl. Deploy it standalone to manage Kubernetes clusters, the workloads running on them, and the cloud infrastructure those workloads depend upon.

Architecture

Crossplane builds on the Kubernetes control plane. It is composed of Stacks - easy to install packages of Kubernetes custom resources and controllers that extend Crossplane with new functionality. A stack can extend Crossplane with the ability to manage the infrastructure of a new cloud provider, or to deploy and manage a new cloud-native application. This enables Crossplane users to:

1. Install the infrastructure stacks for their desired clouds to enable on-demand, cloud-portable provisioning of infrastructure services like databases, caches, and Kubernetes clusters.
2. Define portable application workloads, including their cloud infrastructure dependencies, and schedule them to the most appropriate infrastructure across any cloud.
3. Package their workloads as an application stack that others may easily deploy.

The full vision and architecture of the Crossplane project is described in our architecture document.

Get Started

Take a look at the getting started guide to learn how to install Crossplane, install a stack, and provision cloud infrastructure using kubectl. Refer to the Crossplane documentation for comprehensive guides to using Crossplane, including deploying an application packaged as a stack.
