Building a Platform Engineering API Layer with kcp
summary
kcp presents a horizontally scalable, modified kube-apiserver accepted into the CNCF Sandbox in 2023 that exposes logical clusters as cheap, isolated Kubernetes APIs. It implements API exports (schema-only declarations) and API bindings to register those APIs into workspaces, with controllers reconciling objects through virtual workspaces. Workspaces form a nestable hierarchy and are workspaces created in seconds instead of minutes, enabling a global control plane for an internal API marketplace while controllers run alongside kcp.
