vCluster, virtual Kubernetes clusters that run inside a namespace of a host cluster. The syncer is built from source (CGO off, floated modules); the control plane it runs, kube-apiserver and kube-controller-manager 1.36.4 built from the Kubernetes tag with kine on SQLite, ships in the same image, so no initContainer copies binaries in.
