Crossplane is an open source Kubernetes add-on that extends any cluster with Crossplane is an open source Kubernetes add-on that enables platform teams to
the ability to provision and manage cloud infrastructure, services, and assemble infrastructure from multiple vendors, and expose higher level
applications using kubectl, GitOps, or any tool that works with the Kubernetes self-service APIs for application teams to consume. Crossplane effectively
API. enables platform teams to quickly put together their own opinionated platform
declaratively without having to write any code, and offer it to their
application teams as a self-service Kubernetes-style declarative API.
With Crossplane you can: Both the higher level abstractions as well as the granular resources they are
composed of are represented simply as objects in the Kubernetes API, meaning
they can all be provisioned and managed by kubectl, GitOps, or any tools that
can talk with the Kubernetes API. To facilitate reuse and sharing of these APIs,
Crossplane supports packaging them in a standard OCI image and distributing via
any compliant registry.
