I have embarked on a journey of rewriting Kubernetes into a single binary in Rust, with everything embedded.Architecturally, instead of etcd, it has options to use SQLite or PostgreSQL as a backend. I am trying to make it compatible with Kubernetes APIs, and kubectl should just work out of the box.This is not 100% ready yet, but I just wanted to show the first look. It is almost 90% AI-generated. Claude code with Opus 4.7 is being used here.It should just work out of the box on macOS with Docker as runtime.

Could you build this?
No Rewriting Kubernetes control plane and node agent components into a functional, spec-compliant single binary in Rust demands world-class systems and container runtime engineering.
What it would actually take: Requires a complete rewrite of kube-apiserver, scheduler, controller-manager, and an embedded Kubelet alternative interacting with CRI/CNI plugins. The hardest elements are ensuring strict conformance to Kubernetes API semantics, informers/watch streaming patterns over SQLite/Postgres instead of etcd, and edge-case compatibility with the immense ecosystem of Kubernetes operators and CRDs.
