Unless you absolutely need apiserver-aggregation, you are recommended to use Kubebuilder instead of apiserver-builder for building Kubernetes APIs. Kubebuilder builds APIs using CRDs and addresses limitations and feedback from apiserver-builder.
Apiserver Builder is a collection of libraries and tools to build native Kubernetes extensions using Kubernetes apiserver aggregation. Aggregated apiserver empowers you to customize your apiserver to do following things cannot achieved by CR[D]:
Addon apiservers are a Kubernetes extension point allowing fully featured Kubernetes APIs to be developed on the same api-machinery used to build the core Kubernetes APIS, but with the flexibility of being distributed and installed separately from the Kubernetes project. This allows APIs to be developed outside of the Kubernetes repo and installed separately as a package.
Building addon apiservers directly on the raw api-machinery libraries requires non-trivial code that must be maintained and rebased as the raw libraries change. The goal of this project is to make building apiservers in Go simple and accessible to everyone in the Kubernetes community.
apiserver-builder provides libraries, code generators, and tooling to make it possible to build and run a basic apiserver in an afternoon, while providing all of the hooks to offer the same capabilities when building from scratch.
