The previous commit created the two halves. This one wires the choice, so dev renders MinIO
credentials and prod renders R2 credentials from the SAME base manifests (R-ENV-02: the
overlay patch is the entire difference between environments; no base manifest is forked).
cluster-vars BACKUP_CREDENTIALS_SUFFIX base "" | dev "" | prod "-prod"
velero HelmRelease credentials.existingSecret: velero-cloud-credentials${BACKUP_CREDENTIALS_SUFFIX}
3x CNPG Cluster s3Credentials.*.name: <db>-backup-credentials${BACKUP_CREDENTIALS_SUFFIX}
ONE SUFFIX, NOT FOUR SECRET-NAME KNOBS. Four independent knobs can be updated three-quarters
of the way, leaving one consumer reading the OTHER environment's key with nothing rendering
wrong — and StrictPostBuildSubstitutions cannot catch that: strict mode fails on an UNDEFINED
variable, never on a defined-but-stale one. With one suffix the four move together or not at
all. The cost is that the rendered Secret name is not greppable from the consumer, so both
kustomizations spell the two names out in full beside the resources.
THE BASE DEFAULT IS "" AND THAT IS LOAD-BEARING. It renders the UNSUFFIXED names — objects
that exist in every render, and that dev is running today. The alternative failure mode is
strictly worse than the shared-Secret state this replaces: velero's pod hangs in
ContainerCreating forever when `existingSecret` names a missing Secret (the volume never
mounts), and a CNPG Cluster whose s3Credentials Secret is absent stops archiving WAL — which
under archive_mode=on is a filling pgdata PVC, not a missing backup. So an unresolvable
default breaks the referencing cluster HARDER than a wrong key does. Both overlays state the
value explicitly anyway, so neither inherits it silently.
Prod's overlay change is a cluster-vars op only. The velero Flux Kustomization patch is
untouched (it stays decryption-only, and velero stays suspended on prod).
VERIFIED — `kubectl kustomize --load-restrictor LoadRestrictionsNone` on clusters/dev and
clusters/prod for the cluster-vars values, then on each of the four affected tiers (platform,
platform-config, platform/velero, apps/wave-0) piped through `flux envsubst --strict` with
that environment's variables:
strict envsubst PASSES for all 8 (env x tier) combinations
dev velero existingSecret velero-cloud-credentials
dev keycloak/nextcloud/semaphore-db <db>-backup-credentials (both key refs each)
prod velero existingSecret velero-cloud-credentials-prod
prod keycloak/nextcloud/semaphore-db <db>-backup-credentials-prod (both key refs each)
both all EIGHT Secret objects present in the rendered output (dev and prod alike)
no `${...}` survives in any rendered tier except gitea's three DELIBERATE `$${...}` shell
escapes in apps/wave-0, which are pre-existing and unrelated.
Read alongside the endpoints the same overlays already set, the two environments are now
isolated on credential AND target:
dev velero s3://velero (root) + cnpg s3://cnpg @ http://192.168.1.9:9000 region us-east-1
prod velero k3s-prod-backup/velero + barman prefix @ https://<acct>.r2.cloudflarestorage.com region auto

platform/keycloak
Keycloak — the platform Identity Provider (SSO via OIDC + SAML), onboarded early (Phase 6 IdP).
- Governing ADR: ADR-0014 — IdP: Keycloak
- Spec: docs/15 — Identity & Access
- Serves: R-IDP-01..06
- Owner: WS-SEC
Image / tooling strategy (F-KY1 landmine avoided)
The original stub used the Bitnami Keycloak chart + bundled Bitnami PostgreSQL. Bitnami's free Docker Hub images were purged (DECISIONS-LOG F-KY1) → that path ImagePullBackOffs. Replaced with:
- Keycloak: the official Keycloak Operator (
quay.io/keycloak/keycloak-operator+quay.io/keycloak/keycloak, v26.0.6) driving aKeycloakCR + aKeycloakRealmImportCR for config-as-code (ADR-0014 permits Operator OR Helm; Operator gives clean CR-driven realm reconcile). - Database: CloudNativePG (
ghcr.io/cloudnative-pg, see../cnpg) — aClusteron the 3-replicalonghornStorageClass (DR-critical, R-IDP-05), with declarative backup hooks.
quay.io + ghcr.io are unaffected by the Bitnami purge. Operator manifests are pinned upstream release files pulled as remote kustomize bases (the kubevirt-stub pattern); Renovate maintains the version.

Realm config (groups platform-admins/media-users/viewers, OIDC clients grafana+oauth2-proxy,
brute-force ON, and a conditional MFA browser flow that REQUIRES OTP for platform-admins, R-IDP-04)
reconciles purely from git — no console clicking (R-IDP-03).
Admin credential + break-glass (R-IDP-04 / R-IDP-05)
The provisioned keycloak-admin-credentials.sops.yaml (keys admin-user/admin-password) is injected
as the temporary bootstrap/break-glass admin via KC_BOOTSTRAP_ADMIN_* env (podTemplate escape
hatch) — this consumes the secret as provisioned, without re-keying it (the operator's native
bootstrapAdmin wants username/password keys, which would require editing the encrypted file).
The Keycloak bootstrap admin is the documented break-glass path so an IdP/SSO outage does not lock the
operator out (ADR-0014); Grafana likewise keeps its local admin login until SSO is proven.
Operator hand-offs (fill before / during deploy)
keycloak-realm-clients.sops.yaml(keycloak ns) — from.sops.yaml.example. Two client secrets (grafana-client-secret,oauth2-proxy-client-secret),openssl rand -hex 32each. The realm import injects them into the Keycloak clients viaspec.placeholders. Add tokustomization.yamlonce filled. The realm import stays PENDING until this exists.../oauth2-proxy/oauth2-proxy-credentials.sops.yaml(oauth2-proxy ns) —client-id: oauth2-proxy,client-secret= the SAMEoauth2-proxy-client-secretabove,cookie-secret=openssl rand -base64 32.../monitoring/grafana-oidc-credentials.sops.yaml(monitoring ns) —client-secret= the SAMEgrafana-client-secretabove.
(Cross-namespace Secrets can't be shared, so each client secret is stored twice — once for the realm
import in keycloak, once for the consuming app.) See the two .sops.yaml.example templates for the
exact keys + steps. No plaintext secret is ever committed.
Exceptions that keep native auth (do not force SSO) — ADR-0014
Plex/Seerr (Plex auth), Minecraft (Mojang/Microsoft), UniFi (native).
