jakman85andClaude Opus 4.8 87388712f0 feat(gitea): wire native Keycloak OIDC SSO (break-glass admin retained)
Wires the bootstrapping-critical Gitea git host to the Keycloak `homelab` realm
as a native confidential OIDC client, moving it off the local-admin-only login
while keeping the local admin as the break-glass path (docs/15 availability
caveat; R-IDP-02/06).

Realm (source of truth): add the `gitea` confidential client to
platform/keycloak/keycloak-realm-import.yaml (modeled on grafana) + its
GITEA_CLIENT_SECRET placeholder sourced from the keycloak-realm-clients Secret.
NOTE: a KeycloakRealmImport no-ops on an already-existing realm, so the live
client was ALSO created via kcadm (id 70a6ca60-317a-42ce-8331-a60e380838ee);
the YAML keeps git authoritative for a rebuild.

Secrets (SOPS/age, never plaintext): add gitea-client-secret to
platform/keycloak/keycloak-realm-clients.sops.yaml (keycloak ns) and mirror the
same value as oidc-client-secret into apps/wave-0/gitea-bootstrap-secret.sops.yaml
(gitea ns) so the app can read it in-namespace. Both == the live client secret.

App config (catalog source + re-render): catalog/gitea.yaml gains the
GITEA_OIDC_CLIENT_SECRET env (from the mirrored Secret), [oauth2_client]
auto-registration/account-linking app.ini env, and an idempotent postStart step
that registers the "keycloak" OAuth2 login source (auto-discovery; groups claim;
platform-admins -> Gitea admin). apps/wave-0/gitea.yaml re-rendered via
`render.py --no-image-automation`.

Verified: realm import Done=True/HasErrors=False and platform-config
Ready=True/Healthy=True (unchanged); edited realm YAML passes server dry-run;
static gate (lint/l0/l1) green. Browser SSO login still needs a human check.

catalog — ServiceDefinition entries (the onboarding surface)

One YAML file per service. Each file is a ServiceDefinition conforming to ../schemas/servicedefinition.schema.json. Adding or editing a service here is the only onboarding step — the platform renders compute, storage, network policy, egress, TLS, DNS, monitoring, and update policy from it (see ../schemas/renderer-contract.md). Serves R-GITOPS-02.

Source of truth for the initial catalog: spec docs/13-service-catalog.md (14-service table + SSO/egress/dependency intent).

Current examples (Phase 0)

File docs/13 row exposure egress auth Notes
pihole.yaml 6 internal internet forward-auth admin UI behind oauth2-proxy; config on Longhorn (DR-critical); also platform DNS
keycloak.yaml 0 public internet native the IdP itself (own admin login + MFA); PostgreSQL on Longhorn; DR-critical

The remaining catalog services (plex, sonarr, radarr, jackett, seerr, nextcloud, minecraft, unifi, semaphore, kasm, gitea, qbittorrent) are onboarded in later phases; they follow the same schema and inherit every guarantee automatically.

Authoring rules

  • Only name and source are mandatory; every other field defaults to docs/13's default posture (kind: container, exposure: internal, egress: internet, auth.mode: forward-auth, stable auto-update, DNS-only default-deny). Set a field only to override the default.
  • Any exposed UI must have an auth block: forward-auth (default) or oidc, each with a non-empty auth.groups; native/none are documented exceptions only.
  • Irreplaceable state (class: longhorn configs/DBs) must set backup.policy to an off-cluster schedule — never reacquirable (R-STATE-03). Only bulk media may be reacquirable.

Validate before commit — single command, no cluster (R-TEST-02)

check-jsonschema --schemafile schemas/servicedefinition.schema.json catalog/*.yaml

See ../schemas/README.md for install/pinning and a pure-Python fallback. This is the L0/L1 schema gate (spec docs/14); CI (.gitea/) runs it on every change.

Rendering — render.py (the ServiceDefinition renderer, T-0.3)

render.py compiles a ServiceDefinition into the concrete manifest set defined by ../schemas/renderer-contract.md: a Namespace (with the app-namespace/gateway-access labels), the default-deny baseline (R-NET-01), a Deployment+Service or a KubeVirt VirtualMachine + CDI DataVolume (R-PLAT-02/03), PVCs (R-STATE), one CiliumNetworkPolicy egress-allow per dependency (R-NET-02), the egress-class steering label (R-NET-05), HTTPRoute(s) on the shared Gateway (R-TLS/R-DNS), ServiceMonitor + SLI alerts (R-OBS-01), the Flux ImageRepository/ImagePolicy update plumbing (R-UPD), and the auth-mode / backup wiring hints (R-IDP/R-STATE-03).

python3 catalog/render.py catalog/pihole.yaml        # render one SD to stdout
python3 catalog/render.py --all catalog -o out/      # render every SD to out/<name>.yaml
python3 catalog/render.py --selftest                 # deterministic self-test (no cluster)
  • Deterministic: identical input → byte-identical output (golden-diffable). The L1 render conformance tests (conformance/tests/l1-rendering/*) diff the output against committed goldens — run offline by conformance/run.sh --layer l1 and ci/l1.sh (no cluster).
  • How CI/Flux consume it: CI invokes render.py in the L1 stage; a GitOps flow renders --all catalog -o <rendered-dir> and Flux reconciles the rendered directory. Design choice (renderer-contract is silent on mechanism): a render-then-consume script is the simplest reproducible option — see the header of render.py.
  • Dependency: PyYAML (the renderer's single dependency; the conformance harness stays stdlib-only and only shells out to this script + diffs text).
