Kubernetes
RPCU runs three types of Kubernetes clusters, each with a distinct role.
OpenStack Cluster (baremetal)
The foundation — a baremetal cluster (lucy, makise, quinn) that hosts the entire OpenStack control plane. Bootstrapped with kubeadm, kube-vip HA (VIP 10.0.0.5), Cilium CNI. Not for user workloads.
Management Cluster (CAPI)
Self-managing CAPI cluster on OpenStack VMs (CAPO-provisioned). Hosts the Cluster API providers that manage itself and provision new clusters. Cannot bootstrap itself — requires a temporary kind cluster + clusterctl move pivot.
