Crossplane

Crossplane is a graduated CNCF open-source Kubernetes add-on that transforms a cluster into a universal control plane for cloud infrastructure, services, and applications. Crossplane introduces custom resources including CompositeResourceDefinitions (XRDs), Compositions, Claims, Providers, ProviderConfigs, Configurations, Functions, and EnvironmentConfigs, allowing platform teams to author self-service platform APIs that compose managed resources across AWS, GCP, Azure, and other providers using Kubernetes-style declarative configuration.

Crossplane publishes 7 APIs on the APIs.io network, including CompositeResourceDefinitions API, Compositions API, Configurations API, and 4 more. Tagged areas include Apache 2.0, CNCF, Cloud Native, Composition, and Control Plane.

The Crossplane catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.

Crossplane’s developer surface includes authentication, documentation, getting-started guide, engineering blog, changelog, and 17 more developer resources.
