Crossplane, an open-source project by the Cloud Native Computing Foundation, extends Kubernetes' capabilities by allowing it to manage external IT resources in the same way as internal Kubernetes resources, using familiar tools and configuration strategies. This cloud-native framework serves as a universal control plane, managing not only pods and nodes within a Kubernetes cluster but also external servers and applications through APIs. Unlike traditional Infrastructure-as-Code tools like Terraform, which use standalone frameworks, Crossplane leverages Kubernetes' declarative approach for resource management, enabling developers to describe desired states and allowing Kubernetes to automatically reconcile them. Key features of Crossplane include extensibility through custom resource definitions (CRDs), multi-cloud and hybrid cloud support, continuous reconciliation, policy enforcement, and governance, making it a powerful solution for multi-cloud resource provisioning, infrastructure automation in CI/CD pipelines, and simplifying tooling and account management. Despite its advantages, Crossplane poses a learning curve, relies on provider APIs for functionality, and adds complexity to monitoring and observability, with solutions like groundcover recommended for enhancing visibility. Although not suited for everyone, Crossplane offers a consolidated and declarative resource management experience for those familiar with Kubernetes tooling.
