Written by platform/backup/set-r2-credentials.sh (operator, 2026-09-07T05:41:34Z) into all four consumers, in the two shapes they need: velero wants an AWS INI file, CNPG/barman wants discrete ACCESS_KEY_ID / ACCESS_SECRET_KEY. All four verified to carry the SAME 32-character key id, so no consumer was missed. Proven from a pod INSIDE prod against https://7ce452a1b3d6c86daf2c020edcb82d37.r2.cloudflarestorage.com: head-bucket on k3s-prod-backup returns BucketRegion WNAM, and PUT and DELETE both succeed. Byte-integrity of GET is NOT yet proven (the aws-cli image has no cmp); s3check is what will establish it. Credentials only — no endpoint or bucket wiring. That is feat/r2-backup-prod.

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).
