From 3f980d2a17f0bb481cce44183b5d077828a6f8c2 Mon Sep 17 00:00:00 2001 From: Keith Jackson Date: Mon, 31 Aug 2026 22:43:36 -0500 Subject: [PATCH] feat(env): tokenize hardcoded dev LAN addresses into cluster-vars (R-ENV-02) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit R-ENV-02 promises dev and prod differ ONLY by scoped cluster-vars overrides. In fact dev LAN addresses were hardcoded into base manifests, so clusters/prod would have come up ANNOUNCING DEV ADDRESSES (192.168.1.x) on the prod LAN (192.168.2.x). New cluster-vars knobs (base default = dev literal, per the file's existing convention): K3S_API_HOST platform/cilium/helmrelease.yaml (+ the values.yaml mirror) CILIUM_LB_POOL_START platform-config/cilium/l2-ip-pool.yaml CILIUM_LB_POOL_STOP " UNIFI_L4_VIP apps/vms/unifi/50-service-l4.yaml CRAFTY_L4_VIP platform/crafty/service-l4.yaml S3_BACKUP_ENDPOINT platform/keycloak/postgres-cluster.yaml, apps/wave-0/{nextcloud, semaphore}-db.yaml, and platform/velero/helmrelease.yaml Also fixes GATEWAY_VIP's base default, which was still the RETIRED libvirt address 10.73.0.240, and adds the GATEWAY_VIP patch that clusters/prod was missing entirely. clusters/base/apps-vms.yaml gains postBuild.substituteFrom (it was the one consuming Kustomization without it, so a ${TOKEN} there would have shipped as a literal string). The envsubst contract is documented there: ${VAR} substitutes and escapes as $${VAR}; $VAR and $(cmd) are left alone; ${ARR[0]} hard-errors. The three UOS_URL expansions in the unifi cloud-init are escaped accordingly. PROD ADDRESS PLAN (operator, 2026-08-31): nodes .10/.11/.12 · control-plane VIP .9 (Ansible-side) · GATEWAY_VIP .20 Cilium LB pool .20-.30 CONTAINMENT INVARIANT, now documented at the pool and in the prod overlay: GATEWAY_VIP MUST equal CILIUM_LB_POOL_START. The shared Gateway pins no address, so Cilium LB-IPAM gives it the first free address of a matching pool block. An initial prod proposal put .20 outside a .21-.30 pool; the Gateway would have come up on .21 while split-horizon coredns-custom kept answering *.home.keithjackson.dev with .20 — an address nothing announces — blackholing in-cluster OIDC hairpin traffic while reporting healthy. The pool was widened to .20-.30. The control-plane VIP (.9) stays outside the pool so kube-vip and LB-IPAM can never contend. Values prod still cannot know stay INVALID `TBD-PROD-*` placeholders on purpose: base defaults are dev values, so an omitted patch means prod silently inherits a dev address — far worse than a loud failed apply. DEV IS BYTE-IDENTICAL. Verified by kustomize build over 13 paths before/after, then flux envsubst with the dev cluster-vars values applied to both sides: zero drift. The only deltas are the intended additive keys in the overlay ConfigMap itself. No unresolved ${TOKEN} survives. render-golden green (10 goldens); yamllint clean. Serves: R-ENV-02. Task: T-7.1 (prerequisite). Gate: MERGE GATE: PASS.
