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.

Flux's postBuild.substituteFrom runs envsubst over the WHOLE manifest, including
the VM cloud-init userData. It was substituting every shell `${...}` in the UOS
install script (${UOS_URL}, the API-resolver ${...}) to empty — which is why the
first UOS install silently did nothing — and ${PIPESTATUS[0]} then broke the
build entirely ("missing closing brace"), blocking apps-vms reconcile.
VM manifests use no cluster-vars, so substitution is unneeded. Removed it; the
cloud-init shell now reaches the guest intact. (A future VM needing a cluster-var
must escape its shell `${...}` as `$${...}`.)

First KubeVirt VM app + first real CDI http import. UniFi OS Server (UOS) is
Ubiquiti's current self-host product (the .deb is deprecated); it bundles UniFi
OS + Network app + its own datastore, so no MongoDB companion.
- apps/vms/unifi: CDI DataVolume (Ubuntu 24.04 cloud image -> longhorn-vm
RWX/Block, live-migratable) + VirtualMachine (evictionStrategy: LiveMigrate)
with cloud-init that installs podman/slirp4netns/jq and runs the UOS installer
NON-INTERACTIVELY. The installer URL is resolved at boot from Ubiquiti's public
firmware API (fw-update.ui.com/api/firmware-latest) — always-latest, no pinned
URL to maintain (currently UOS v5.1.37).
- L4 exposure: two LoadBalancer Services (TCP+UDP) sharing a pinned, L2-announced
Cilium VIP 192.168.1.54 (device inform/adoption + STUN can't ride the L7
Gateway); external-dns publishes unifi.home.keithjackson.dev. UI on :11443.
- default-deny + additive CNPs (controller ingress, egress, and CDI-importer
egress for the image pull).
- clusters/base/apps-vms.yaml: NON-GATING Flux Kustomization (wait:false,
dependsOn platform-config) — VMs are a separate lifecycle from the app waves,
so a slow VM import/install can't stall the app tier.
