**APIs profiled:** 7

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 CompositeResourceDefinitions API** — CompositeResourceDefinitions (XRDs) extend the Kubernetes API with new custom resource types. An XRD defines the schema and API surface for a composite resource and an optional ...
- **Crossplane Compositions API** — Compositions define how to compose a set of managed resources or Composition Functions into a higher-level composite resource. A Composition acts as a template that maps fields ...
- **Crossplane Configurations API** — Configurations are Crossplane packages that bundle Compositions and CompositeResourceDefinitions together into a distributable unit that can be installed into a Crossplane contr...
- **Crossplane DeploymentRuntimeConfigs API** — DeploymentRuntimeConfigs customize the runtime behavior of Provider and Function deployments, including replica counts, resource limits, service account annotations, and pod tem...
- **Crossplane EnvironmentConfigs API** — EnvironmentConfigs provide shared configuration data that can be referenced by Compositions via environment patches, enabling reusable configuration across multiple Compositions.
- **Crossplane Functions API** — Functions are Crossplane packages that contain Composition Functions, which are OCI container images invoked during composition to perform advanced resource templating and trans...
- **Crossplane Providers API** — Providers are Crossplane packages that install controllers and CRDs for managing resources on a specific infrastructure platform such as AWS, GCP, or Azure.
