### [Declarative clusters: GitOps deployment of hosted control planes on Red Hat OpenShift Virtualization](https://yomu.fyi/post/declarative-clusters-gitops-deployment-of-hosted-control-planes-on-red.md)

Hosted control planes for Red Hat OpenShift, based on the HyperShift project, decouple the cluster control plane from worker nodes by running control-plane components as pods inside a central management cluster. On bare-metal infrastructure, OpenShift Virtualization provisions worker nodes as virtual machines, enabling live migration and reducing hardware requirements. The article presents a declarative GitOps workflow using Helm templates and an Argo CD ApplicationSet that dynamically generates deployments from tenant-specific YAML configuration files in Git. Prerequisites include a bare-metal management cluster with OpenShift Virtualization, Red Hat Advanced Cluster Management, and OpenShift GitOps, plus networking configured with NMState, Multus CNI, and MetalLB. The approach achieves a “Cluster-as-a-Service” model where provisioning a production-grade cluster requires only a Git push.
