Metadata is essential for grouping resources, redirecting requests and managing deployments. The effectiveness of the Kubernetes API comes from how it manages the Kubernetes resources via metadata: labels and annotations. It also provides a very flexible and developer-friendly API, which is the foundation of its control plane.
