-Repository Guidelines
-
-## Project Structure & Module Organization
-- `infrastructure/`: cluster-scoped building blocks (core, flux-system, traefik, longhorn). Add new platform features by mirroring this layout.
-- `services/`: workload manifests per app (`services/gitea/`, etc.) with `kustomization.yaml` plus one file per kind; keep diffs small and focused.
-- `dockerfiles/` hosts bespoke images, while `scripts/` stores operational Fish/Bash helpers—extend these directories instead of relying on ad-hoc commands.
-
-## Build, Test, and Development Commands
-- `kustomize build services/<app>` (or `kubectl kustomize ...`) renders manifests exactly as Flux will.
-- `kubectl apply --server-side --dry-run=client -k services/<app>` checks schema compatibility without touching the cluster.
-- `flux reconcile kustomization <name> --namespace flux-system --with-source` pulls the latest Git state after merges or hotfixes.
-- `fish scripts/flux_hammer.fish --help` explains the recovery tool; read it before running against production workloads.
-
-## Coding Style & Naming Conventions
-- YAML uses two-space indents; retain the leading path comment (e.g. `# services/gitea/deployment.yaml`) to speed code review.
-- Keep resource names lowercase kebab-case, align labels/selectors, and mirror namespaces with directory names.
-- List resources in `kustomization.yaml` from namespace/config, through storage, then workloads and networking for predictable diffs.
-- Scripts start with `#!/usr/bin/env fish` or bash, stay executable, and follow snake_case names such as `flux_hammer.fish`.
-
-## Testing Guidelines
-- Run `kustomize build` and the dry-run apply for every service you touch; capture failures before opening a PR.
-- `flux diff kustomization <name> --path services/<app>` previews reconciliations—link notable output when behavior shifts.
-- Docker edits: `docker build -f dockerfiles/Dockerfile.monerod .` (swap the file you changed) to verify image builds.
-
-## Commit & Pull Request Guidelines
-- Keep commit subjects short, present-tense, and optionally scoped (`gpu(titan-24): add RuntimeClass`); squash fixups before review.
-- Describe linked issues, affected services, and required operator steps (e.g. `flux reconcile kustomization services-gitea`) in the PR body.
-- Focus each PR on one kustomization or service and update `infrastructure/flux-system` when Flux must track new folders.
-- Record the validation you ran (dry-runs, diffs, builds) and add screenshots only when ingress or UI behavior changes.
-
-## Security & Configuration Tips
-- Never commit credentials; use Vault workflows (`services/vault/`) or SOPS-encrypted manifests wired through `infrastructure/flux-system`.
-- Node selectors and tolerations gate workloads to hardware like `hardware: rpi4`; confirm labels before scaling or renaming nodes.
-- Pin external images by digest or rely on Flux image automation to follow approved tags and avoid drift.
-
-## Dashboard roadmap / context (2025-12-02)
-- Atlas dashboards are generated via `scripts/dashboards_render_atlas.py --build`, which writes JSON under `services/monitoring/dashboards/` and ConfigMaps under `services/monitoring/`. Keep the Grafana manifests in sync by regenerating after edits.
-- Atlas Overview panels are paired with internal dashboards (pods, nodes, storage, network, GPU). A new `atlas-gpu` internal dashboard holds the detailed GPU metrics that feed the overview share pie.
-- Old Grafana folders (`Atlas Storage`, `Atlas SRE`, `Atlas Public`, `Atlas Nodes`) should be removed in Grafana UI when convenient; only `Atlas Overview` and `Atlas Internal` should remain provisioned.
-- Future work: add a separate generator (e.g., `dashboards_render_oceanus.py`) for SUI/oceanus validation dashboards, mirroring the atlas pattern of internal dashboards feeding a public overview.
-
-## Monitoring state (2025-12-03)
-- dcgm-exporter DaemonSet pulls `registry.bstein.dev/monitoring/dcgm-exporter:4.4.2-4.7.0-ubuntu22.04` with nvidia runtime/imagePullSecret; titan-24 exports metrics, titan-22 remains NotReady.
-- Atlas Overview is the Grafana home (1h range, 1m refresh), Overview folder UID `overview`, internal folder `atlas-internal` (oceanus-internal stub).
-- Panels standardized via generator; hottest row compressed, worker/control rows taller, root disk row taller and top12 bar gauge with labels. GPU share pie uses 1h avg_over_time to persist idle activity.
-- Internal dashboards are provisioned without Viewer role; if anonymous still sees them, restart Grafana and tighten auth if needed.
-
-## Upcoming priorities (SSO/storage/mail)
-- Establish SSO (Keycloak or similar) and federate Grafana, Gitea, Zot, Nextcloud, Pegasus/Jellyfin; keep Vaultwarden separate until safe.
-- Add Nextcloud (limit to rpi5 workers) with office suite; integrate with SSO; plan storage class and ingress.
-- Plan mail: mostly self-hosted, relay through trusted provider for outbound; integrate with services (Nextcloud, Vaultwarden, etc.) for notifications and account flows.
-
-## SSO plan sketch (2025-12-03)
-- IdP: use Keycloak (preferred) in a new `sso` namespace, Bitnami or codecentric chart with Postgres backing store (single PVC), ingress `sso.bstein.dev`, admin user bound to brad@bstein.dev; stick with local DB initially (no external IdP).
-- Auth flow goals: Grafana (OIDC), Gitea (OAuth2/Keycloak), Zot (via Traefik forward-auth/oauth2-proxy), Jellyfin/Pegasus via Jellyfin OAuth/OpenID plugin (map existing usernames; run migration to pre-create users in Keycloak with same usernames/emails and temporary passwords), Pegasus keeps using Jellyfin tokens.
-- Steps to implement:
-  1) Add service folder `services/keycloak/` (namespace, PVC, HelmRelease, ingress, secret for admin creds). Verify with kustomize + Flux reconcile.
-  2) Seed realm `atlas` with users (import CSV/realm). Create client for Grafana (public/implicit), Gitea (confidential), and a “jellyfin” client for the OAuth plugin; set email for brad@bstein.dev as admin.
-  3) Reconfigure Grafana to OIDC (disable anonymous to internal folders, leave Overview public via folder permissions). Reconfigure Gitea to OIDC (app.ini).
-  4) Add Traefik forward-auth (oauth2-proxy) in front of Zot and any other services needing headers-based auth.
-  5) Deploy Jellyfin OpenID plugin; map Keycloak users to existing Jellyfin usernames; communicate password reset path.
-- Migration caution: do not delete existing local creds until SSO validated; keep Pegasus working via Jellyfin tokens during transition.
-
-## Postgres centralization (2025-12-03)
-- Prefer a shared in-cluster Postgres deployment with per-service databases to reduce resource sprawl on Pi nodes. Use it for services that can easily point at an external DB.
-- Candidates to migrate to shared Postgres: Keycloak (realm DB), Gitea (git DB), Nextcloud (app DB), possibly Grafana (if persistence needed beyond current provisioner), Jitsi prosody/JVB state (if external DB supported). Keep tightly-coupled or lightweight embedded DBs as-is when migration is painful or not supported.

+Keycloak is deployed via raw manifests and backed by the shared Postgres (`postgres-service.postgres.svc.cluster.local:5432`). Create these secrets before applying:
+
+```bash
+# DB creds (per-service DB/user in shared Postgres)
+kubectl -n sso create secret generic keycloak-db \
+  --from-literal=username=keycloak \
+  --from-literal=password='<DB_PASSWORD>' \
+  --from-literal=database=keycloak
+
+# Admin console creds (maps to KC admin user)
+kubectl -n sso create secret generic keycloak-admin \
+  --from-literal=username=brad@bstein.dev \
+  --from-literal=password='<ADMIN_PASSWORD>'
+```
+
+Apply:
+
+```bash
+kubectl apply -k services/keycloak
+```
+
+Notes
+- Service: `keycloak.sso.svc:80` (Ingress `sso.bstein.dev`, TLS via cert-manager).
+- Uses Postgres schema `public`; DB/user should be provisioned in the shared Postgres instance.
+- Health endpoints on :9000 are wired for probes.
