# clusters/prod — DESIGN-ONLY overlay. NOT a build target until roadmap Phase 7 opens prod
# (spec roadmap/phases.md, AGENTS.md §6: "Never build directly on production").
#
# When Phase 7 is opened, `flux bootstrap ... --path=clusters/prod` points the prod cluster's Flux
# here. Like dev, this overlay adds NO resources — it ONLY patches cluster-vars with prod-scoped
# values (R-ENV-02). Promotion to prod is a change to THESE variables, never a base edit.
#
# *** PHASE-7 BLOCKER — READ BEFORE BOOTSTRAPPING PROD ***
# `clusters/base/platform.yaml` now carries `dependsOn: [flux-system]` (the 2026-09-01 substitution-
# race fix). That names the ROOT Kustomization, which clusters/dev supplies as `dev/sync.yaml`
# (path ./clusters/dev). THIS overlay has no sync.yaml yet, so as written a prod bootstrap would
# leave `platform` stuck on "dependency 'flux-system/flux-system' is not ready" FOREVER and nothing
# downstream would reconcile. Phase 7 MUST add `clusters/prod/sync.yaml` — a copy of dev/sync.yaml
# with `path: ./clusters/prod` — as part of opening this overlay. (Adding it now is deliberately NOT
# done here: prod is design-only and its root object is the prod bring-up owner's call.)

  # ###   any cluster. It exists ONLY to get prod's first reconcile off the ground. It MUST   ###
  # ###   be cut over to the in-cluster URL once Gitea runs on prod. If you are reading this  ###
  # ###   and prod has been serving traffic for months, THE CUTOVER WAS NEVER DONE — that is  ###
  # ###   a live single point of failure, not a settled design. See "CUTOVER" below.          ###
  # ###                                                                                      ###
  # ############################################################################################
  #
  # WHY THE IN-CLUSTER URL CANNOT BE USED YET (blocker found 2026-09-01, still true; the
  # unusable value was `https://gitea.home.keithjackson.dev/Home-Network/home-network-k3s-impl.git`).
  # REASONING UPDATED 2026-09-04 for the new suffix direction (prod = the apex, dev = dev.home.),
  # which changes WHY the blocker holds but not THAT it holds:
  #   1. SELF-HOSTING CIRCULARITY — still true, and now the only reason. The Gitea this repo is
  #      pushed to runs ON THE DEV CLUSTER. Prod syncing from it would put prod's GitOps source
  #      inside the very cluster slated for decommission. Gitea must move to prod (or off-cluster)
  #      BEFORE dev is retired, or prod loses its source of truth.
  #      NOTE the suffix change makes the two Giteas DIFFERENT HOSTS: dev's is now
  #      gitea.dev.home.keithjackson.dev and prod's is gitea.home.keithjackson.dev. Prod pointing at
  #      the apex name therefore means "prod's OWN Gitea", never dev's — which is what makes the
  #      cutover below a one-line change once prod actually runs Gitea.
  #   2. SPLIT-HORIZON DNS — NO LONGER A BLOCKER, and the note is kept because the old reasoning is
  #      easy to re-derive incorrectly. platform/coredns/coredns-custom.yaml answers the whole
  #      ${BASE_DOMAIN} zone with ${GATEWAY_VIP}; when prod's BASE_DOMAIN was `prod.home.` that meant
  #      prod resolved gitea.home.keithjackson.dev to PROD's gateway (192.168.2.20) where no Gitea
  #      listened — a misdirection. Now that prod IS the apex, resolving gitea.home.keithjackson.dev
  #      to prod's own Gateway is CORRECT: that is where prod's Gitea will be served from. What
  #      remains is purely reason 1 — the Gitea is not there YET.
  #
  # WHAT THE TEMPORARY SOURCE IS (stood up 2026-09-04 on explicit operator direction):
  #   bootstrap/gitea/bootstrap-gitea.sh with HOST_NAT_IP=192.168.2.132 — a podman container on the
  #   operator's workstation, Gitea 1.22.6, listening on 192.168.2.132:3000. All three prod nodes
  #   reach it DIRECTLY on the LAN: no libvirt NAT hop (that network is retired) and no firewall
  #   change was needed. This is the same "local bootstrap source" pattern dev itself used before
  #   its Phase-6 cutover (docs/05 "Source-of-truth").
  #
  # PLAIN HTTP, AND WHY THAT IS ACCEPTED HERE: the bootstrap Gitea has no TLS, so there is no cert
  # for Flux to trust and no caCertSecretRef to wire. Traffic is LAN-local between prod nodes and
  # the workstation, the repo carries NO plaintext secrets (everything sensitive is SOPS-encrypted,
  # .sops.yaml), and the window is the bring-up only. Do NOT extend this posture past cutover.
  #
  # NO secretRef, DELIBERATELY: the repo is PUBLIC on the bootstrap Gitea, so anonymous clone
  # works and Flux needs no git credentials. VERIFIED 2026-09-04 by unauthenticated request:
  #   curl http://192.168.2.132:3000/api/v1/repos/Home-Network/home-network-k3s-impl -> "private":false
  #   git ls-remote http://192.168.2.132:3000/Home-Network/home-network-k3s-impl.git  -> refs/heads/main
  # If the GitRepository ever reports an auth failure that looks like a network problem, RE-CHECK
  # THAT FIRST: a private repo here fails exactly that way.
  #
  # *** CUTOVER — the exit condition, mirroring dev's Phase-6 cutover (docs/05) ***
  #   WHEN: Gitea runs on prod (reconciled in-cluster) and answers gitea.home.keithjackson.dev
  #         through prod's own Gateway VIP with a publicly-trusted cert.
  #   DO:   1. push/mirror this repo into the prod in-cluster Gitea;
  #         2. change the url below to
  #            https://gitea.home.keithjackson.dev/Home-Network/home-network-k3s-impl.git
  #            and DELETE this whole TEMPORARY block (dev's equivalent stanza, ~15 lines above in
  #            clusters/dev/kustomization.yaml, is what "done" looks like);
  #         3. confirm `flux get sources git -n flux-system` reconciles the new revision;
  #         4. only THEN stop the workstation container. Keep it stopped-not-deleted as recovery,
  #            exactly as dev retained its bootstrap Gitea.
  #   UNTIL THEN: prod's reconciliation depends on a container on a workstation that may be
  #   powered off. Flux keeps the last-reconciled state running, but NO new revision lands while
  #   it is down. Tracked as an open blocker in infra/PROD-PROVISIONING.md §7.
  #
  # The BRANCH below is settled and correct: prod tracks `main`, the same branch as dev.
  # CONSEQUENCE, recorded deliberately: once prod is live, EVERY MERGE TO main RECONCILES BOTH
  # CLUSTERS. There is no promotion step and no soak window — dev and prod move together.
  # NOTE for bring-up: bootstrap-gitea.sh pushes the operator's CURRENT HEAD to the bootstrap
  # Gitea's `main`, whatever branch that is. Before bootstrapping prod, confirm that remote `main`
  # is the revision you intend prod to run (`git ls-remote` above, against local `main`).

      # ==========================================================================================
      # OPERATOR DECISION 2026-09-04, superseding the interim split committed earlier the same day
      # (prod on `prod.home.` behind apex CNAMEs). The simpler target, and the one authored here:
      #
      #   dev   -> dev.home.keithjackson.dev     (dev carries the label; clusters/dev)
      #   prod  -> home.keithjackson.dev         (THE APEX — this knob)
      #
      # There is NO `prod.` label and NO CNAME layer. `<svc>.home.keithjackson.dev` is prod's REAL
      # name, so nothing has to alias anything: prod's Gitea is gitea.home.keithjackson.dev, its
      # Keycloak keycloak.home.keithjackson.dev, and the wildcard cert is `*.home.keithjackson.dev`.
      #
      # BACKGROUND — WHY THE SUFFIXES HAD TO SPLIT AT ALL. Until 2026-09-04 every hostname was
      # HARDCODED to home.keithjackson.dev in the base manifests, so prod was authored to serve the
      # EXACT SAME public names as the live dev cluster out of the SAME Cloudflare zone. Two
      # consequences, one of which already happened:
      #   1. HAPPENED: prod's external-dns (policy: sync, owner id `default` — the same implicit
      #      default dev had) concluded it owned dev's records and DELETED EVERY ONE of them.
      #   2. QUEUED BEHIND IT: platform-config would have requested a `*.home.keithjackson.dev`
      #      wildcard from letsencrypt-prod for a cert dev already holds, and both clusters would
      #      have raced each other's `_acme-challenge` TXT records on that one zone.
      #
      # *** THE ORDERING CONSTRAINT THIS VALUE CREATES — READ BEFORE UNSUSPENDING ANYTHING. ***
      # Prod now claims the very names the LIVE dev cluster is serving today. Both hazards above are
      # therefore still armed until DEV HAS VACATED THE APEX. Prod's `platform` and its 10 downstream
      # tiers are SUSPENDED for exactly this reason. The gate is not "review is done", it is:
      #   (a) dev is reconciling on *.dev.home.keithjackson.dev with a Ready wildcard cert, AND
      #   (b) dev's old apex A/CNAME records and their TXT registry entries are GONE from Cloudflare
      #       (verified against Cloudflare directly — the workstation's dnsmasq is NOT evidence about public
      #       DNS; that mistake was made on 2026-09-04), AND
      #   (c) dev's old `*.home.keithjackson.dev` cert/Certificate is released, because prod ordering
      #       that same name set while dev's still exists counts against LE's duplicate-certificate
      #       limit (5 per week per identical name set).

      # OFF-CLUSTER DR TARGET — Cloudflare R2 (operator, 2026-09-05).
      #
      # THERE IS DELIBERATELY NO `S3_BACKUP_ENDPOINT` OP HERE, and that is a reversal of the rule
      # stated at the top of this overlay ("an OMITTED op means prod silently inherits a dev
      # address"). That rule exists because base defaults are dev's LAN addresses. R2 is not one: it
      # is a single shared, environment-independent endpoint, so under R-ENV-02 it belongs in base and
      # overriding it with an identical value would only create two places to change on a rotation —
      # the exact drift this repo has been bitten by before. Isolation does NOT come from the
      # endpoint; it comes from the two path knobs below.
      #
      # WHY R2 AND NOT THE MinIO the operator first named: prod is on the SOHO network
      # 192.168.2.0/24, which is pfSense's WAN, while the MinIO sits inside pfSense's LAN
      # 192.168.1.0/24. Measured from a pod INSIDE prod (the workstation proves nothing about pod
      # egress): `curl http://192.168.1.9:9000/minio/health/live` → connection timed out after 15s.
      # Reaching it would need a WAN→LAN rule that does not exist. R2 needs no firewall change, and
      # unlike that MinIO — which runs on the same Proxmox host as dev's VMs — it is genuinely
      # off-site. Verify prod can reach the new endpoint before resuming velero:
      #   bootstrap/standup.sh ... --s3-endpoint <the R2 endpoint> s3check
      #
      # THE PATH KNOBS ARE WHAT MAKE ONE SHARED BUCKET SAFE. Nothing about the paths was
      # per-environment before 2026-09-05: Velero used one unprefixed bucket, and every CNPG Cluster
      # used `s3://cnpg` with serverName defaulting to the CLUSTER NAME — and both environments have
      # keycloak-db / nextcloud-db / semaphore-db. Without these knobs prod would (a) adopt and
      # TTL-delete dev's Velero backups and (b) interleave two Postgres servers' WAL into ONE Barman
      # stream, corrupting the chain and destroying PITR for both. See clusters/base/cluster-vars.yaml.
