Add an HA control-plane API VIP for the k3s cluster with kube-vip, and add the VIP + all node IPs to the kube-apiserver serving-cert SANs so TLS via the VIP validates. Prepares the stable failover endpoint the operator fronts with a pfSense port-forward to 192.168.1.49:6443. roles/kube_vip + playbooks/kube-vip.yml: - Templates a single manifest (RBAC + DaemonSet kube-vip-ds) into each server's k3s auto-deploy dir (/var/lib/rancher/k3s/server/manifests) so it is reproducible and independent of Flux; k3s auto-applies it. - Control-plane ONLY (cp_enable=true, svc_enable=false): Cilium keeps ownership of Service LoadBalancing (L2 pool .53-.60) — no ARP conflict. - Runs on control-plane nodes (nodeSelector node-role.kubernetes.io/control-plane), hostNetwork, NET_ADMIN/NET_RAW, image pinned ghcr.io/kube-vip/kube-vip:v0.8.9. - vip_interface auto-detected per node (the iface holding 192.168.1.5x = eth0). - Leader election (plndr-cp-lock) with 15/10/2s lease timings. - This cluster runs without kube-proxy (Cilium replacement), so a hostNetwork pod cannot reach the kubernetes ClusterIP; kube-vip is pointed at the node-local apiserver (KUBERNETES_SERVICE_HOST=127.0.0.1:6443) so leader election works. roles/k3s_server tls-san: - New k3s_tls_sans (VIP + all three node IPs + 127.0.0.1, deduped); install args now emit one --tls-san per entry. - Persist the SAN list to /etc/rancher/k3s/config.yaml (read by a running k3s) and Restart k3s handler so an existing cluster regenerates its serving cert. - k3s.yml secondaries run serial:1 so a SAN change rolls one node at a time, keeping etcd quorum (kube-vip keeps the API reachable during each restart). Verified live: DS 3/3 ready, VIP answers on 192.168.1.49:6443, all 3 certs and an s_client against the VIP carry 192.168.1.49 + .50/.51/.52 + 127.0.0.1, all nodes Ready throughout the rolling restart.

home-network-k3s-impl
Implementation of the home k3s + Longhorn platform. This repo holds the reconciled artifacts
(Flux config, Kustomize overlays, KubeVirt/Helm manifests, ServiceDefinitions, Kyverno policies,
Chainsaw conformance tests, CI). It is driven by — and subordinate to — the read-only
specification at ../home-network-k3s.
Rules (from the spec — non-negotiable)
- The spec is read-only. Never modify anything under
../home-network-k3s. Implement against it; escalate spec problems, don't edit them (specAGENTS.md§11, R-TEST-06). - Done = a green, reproducible, requirement-tagged conformance test — never "merged," never a
manual demo (spec
docs/14,agents/definition-of-done.md). - No work on
main. Every change is a feature branch merged intomain(specCONTRIBUTING.md). - No plaintext secrets — SOPS-encrypted only (spec
docs/07). - Phase discipline — only build what the active roadmap phase authorizes (spec
roadmap/phases.md).
