# infra/cluster.sh — RETIRED (libvirt era). DO NOT USE.
#
# This managed the ORIGINAL dev cluster: 3 libvirt/KVM VMs on the workstation, on the
# 10.73.0.0/24 NAT network. That cluster no longer exists — the dev cluster was migrated to
# Proxmox VE (nodes 192.168.1.50/.51/.52) and there are no local `k3s-dev-*` domains for
# virsh to start or stop. It is kept only as a record of the retired lifecycle.
#
# What to use instead (see infra/PHASE1-STATUS.md):
#   VM power        — the Proxmox UI / API on the Proxmox host, or `tofu` in infra/tofu
#   kubeconfig      — ~/.kube/config context `k3s-oidc` (Keycloak SSO), or the break-glass
#                     cert kubeconfig from the primary node
#   node access     — ssh -p 225{0,1,2} k3s@192.168.2.102  (pfSense NAT)
#   cluster health  — kubectl get nodes && flux get kustomizations
