fix(sso): postStart hooks must exit 0 — nextcloud crashlooped the moment OIDC ran
LIVE REGRESSION, caught on the reconcile after merging #5. nextcloud went
CrashLoopBackOff with FailedPostStartHook, 7 restarts, and apps-wave-1/2 stalled.
ROOT CAUSE — a latent bug that could never fire until now. The final statement of
nextcloud's postStart script was:
[ "$p" -ge 15 ] && nextcloud_oidc_fail "could not promote ... after retries"
On the SUCCESS path (p < 15) the test returns 1, and as the script's LAST command that
becomes the hook's exit status. A non-zero postStart exit makes the kubelet KILL the
container. This was harmless for as long as the OIDC guard above it was dead code that
exited 0 first (see

fix(sso): gitea + nextcloud OIDC bootstrap was DEAD CODE — envsubst ate the guard
Both ServiceDefinitions guarded their Keycloak OIDC registration with an UNESCAPED
braced expansion:
if [ -z "${GITEA_OIDC_CLIENT_SECRET:-}" ]; then # gitea
if [ -z "${NEXTCLOUD_OIDC_CLIENT_SECRET:-}" ]; then # nextcloud, then exit 0
apps-wave-0/1 both declare postBuild.substituteFrom: cluster-vars, and neither name is a
cluster-vars key — so Flux's envsubst substituted them away AT RECONCILE TIME, long
before the container ever ran. Verified in the LIVE cluster: the deployed Deployments
literally contain
if [ -z "" ]; then
which is always true. The entire OIDC registration block has been skipped on EVERY boot
of both apps.
WHY NOBODY NOTICED: both apps DO have the provider registered — `gitea admin auth list`
shows keycloak/OAuth2/true and `occ user_oidc:provider` shows the keycloak provider.
Those live in each app's own database, persisted from an earlier successful registration.
SSO works today and DECISIONS-LOG is not wrong. But the idempotent re-registration is
dead, so any PVC rebuild, DB restore, or fresh cluster build comes up with NO OIDC and
only the break-glass local admin. A PROD BUILD FROM THIS REPO WOULD SILENTLY HAVE NO SSO
on gitea or nextcloud.
The irony: the surrounding code was hardened twice — see its own comments about a "silent
first-boot RACE", the verify-then-retry loops, the marker files. All of that hardening was
unreachable, because the guard above it always evaluated true.
Not a regression from the recent R-ENV-02 tokenization — introduced 2026-08-27 (

fix(nextcloud-sso): apply step-(d) retry hardening at SOURCE (catalog)
apps/wave-1/nextcloud.yaml is GENERATED from catalog/nextcloud.yaml by catalog/render.py, so the previous commit hardened only the rendered golden — the next render would have reverted step (d) to the old single-pass version. Apply the same verify-and-retry hardening to the postStart hook in catalog/nextcloud.yaml (the source of truth). Re-rendered with `render.py --all catalog -o apps --wave-layout`; apps/wave-1/nextcloud.yaml is byte-identical to the golden committed in the previous commit (render round-trip clean), so no apps/ change is needed here.

fix(nextcloud): allow SSRF to private IdP + promote platform-admins to admin
Task 1 — browser SSO "Could not reach OpenID Connect provider" (confirmed root cause, not guessed). keycloak.home.keithjackson.dev resolves split-horizon to the PRIVATE Cilium gateway VIP (192.168.1.53). Nextcloud's SSRF guard refuses its own server-side HTTP requests to RFC1918 addresses, so user_oidc's discovery/JWKS/token fetch AT LOGIN throws OCP\Http\Client\LocalServerException "violates local access rules" -> surfaced to the user as "Could not reach the provider". Proven from the live pod: nextcloud.log carries the exact LocalServerException from DiscoveryService::obtainDiscovery with Guzzle option allow_local_address:false; a Nextcloud-context IClientService->get() of the discovery URL returns LocalServerException with the flag false and HTTP 200 with it true (A/B toggled). The postStart (b) curl check passed regardless because it uses system libcurl, not Nextcloud's guard — which is why the provider registered yet login still failed. Fix (reproducible, survives pod rolls): the postStart hook now runs `occ config:system:set allow_local_remote_servers --value=true --type=boolean` right after the install/maintenance wait, on every start. Task 2 — promote Keycloak `platform-admins` members to Nextcloud admins (#5). user_oidc 8.11 has NO native group->admin mapping (occ user_oidc:provider offers group PROVISIONING and a login WHITELIST only), so the hook mirrors the provisioned `platform-admins` membership into the built-in `admin` group idempotently (occ group:list --output=json parsed via php argv; occ group:adduser admin per member). A user is promotable after their first OIDC login provisions them + the next pod start (or one manual `occ group:adduser admin <uid>`). The LOCAL admin stays as break-glass (docs/15). apps/wave-1/nextcloud.yaml re-rendered from catalog (single-file render; byte-diff confined to the embedded hook). Rendered hook passes `sh -n`; parse step validated in-pod. `make -C ci gate` green (lint/l0/l1; conformance + spec-immutability skip: no cluster / spec repo unmounted).

fix(oidc): make gitea + nextcloud OIDC login-source registration persist
The Keycloak OIDC postStart registration for gitea and nextcloud ran but never persisted, leaving `gitea admin auth list` empty and nextcloud's user_oidc with "No providers configured" despite the apps installing/ enabling and the client secret being present. Two distinct root causes, confirmed by running the registration manually against the live warm pods: - nextcloud: a QUOTING BUG, not a race. The OCC() wrapper runs `su -c "php occ $*"`, which word-split `--scope="openid email profile"` back into three tokens, so occ saw `email profile` as extra positional args -> "Too many arguments to user_oidc:provider" -> exit 1, swallowed by `|| echo failed`. Failed on EVERY boot. Fixed by running the provider call as ONE `su -c` with the scope single-quoted so www-data's shell keeps it a single argument; keep the OCC() wrapper only for single-token subcommands. - gitea: a first-boot RACE. The direct `admin auth add-oauth` persists once the app/network is warm (verified live), but fired too early at postStart and its failure was swallowed (`|| echo ... >&2`, exit 0). Hardening applied to both catalog sources (rendered into apps/wave-*): - wait (bounded ~90s) for the Keycloak discovery doc to return HTTP 200; - nextcloud also waits for `installed: true` AND `maintenance: false`; - register idempotently (create-or-update) then VERIFY the source/provider actually persisted, retrying the whole cycle (guards exit-0-but-nothing- stuck); - on give-up, log LOUDLY to stderr AND a marker file on the persistent volume (/data, /var/www/html) instead of swallowing — next failure is visible; - never crashloop: missing-secret guard retained, break-glass local admin stays usable.

feat(nextcloud,semaphore): wire native Keycloak OIDC SSO (break-glass admins retained)
Extends the SSO work to the two remaining `auth: oidc` apps still on local-admin
logins, each as a native confidential client of the Keycloak `homelab` realm with
its local admin kept as break-glass (docs/15 availability caveat; R-IDP-02/06).
Realm (source of truth): add the `nextcloud` and `semaphore` confidential clients
to platform/keycloak/keycloak-realm-import.yaml (modeled on grafana/gitea) + their
NEXTCLOUD_CLIENT_SECRET / SEMAPHORE_CLIENT_SECRET placeholders. As before, a
KeycloakRealmImport no-ops on an already-existing realm, so both live clients were
ALSO created via kcadm (nextcloud e95049ed-ca10-4085-97d9-4bbef495fe61, semaphore
1835bfe9-b125-4026-8f69-33557519cf4a); the YAML keeps git authoritative.
Secrets (SOPS/age): add nextcloud-client-secret + semaphore-client-secret to
keycloak-realm-clients.sops.yaml (keycloak ns). Mirror the nextcloud secret as
oidc-client-secret into nextcloud-bootstrap (nextcloud ns). For semaphore, the
whole SEMAPHORE_OIDC_PROVIDERS JSON (which embeds the client secret) is held
encrypted as oidc-providers-json in semaphore-bootstrap (semaphore ns). All values
verified == the live clients; existing keys untouched; no plaintext in git.
App config (catalog source + re-render):
- nextcloud: add NEXTCLOUD_OIDC_CLIENT_SECRET env + an idempotent postStart hook
that installs/enables user_oidc and runs `occ user_oidc:provider keycloak`
(create-or-update; secret via --clientsecret-env so it never hits argv; occ as
www-data; group provisioning on the `groups` claim). Syntax verified against the
running user_oidc 8.11.0 on Nextcloud 31.0.14; su-to-www-data env passthrough
verified. Missing-secret/not-installed guards prevent crashloops.
- semaphore: add SEMAPHORE_OIDC_PROVIDERS env sourced from the encrypted
oidc-providers-json (provider_url=realm issuer/auto-discovery, redirect
/api/auth/oidc/keycloak/redirect). Mechanism verified against semaphore v2.19.10
source (util ConfigType oidc_providers env tag + OidcProvider struct + router
redirect path); no kubelet service-link env collision.
apps/wave-1/{nextcloud,semaphore}.yaml re-rendered via
`render.py --no-image-automation` (diffs are env/lifecycle-only).
Verified: realm import Done=True/HasErrors=False and platform-config
Ready=True/Healthy=True (unchanged); edited realm YAML passes server dry-run; live
homelab clients now include gitea/nextcloud/semaphore; static gate (lint/l0/l1)
green. Browser SSO login for each still needs a human check.

feat(apps): onboard nextcloud (Phase 6) — first CNPG-DB + OIDC-target patterns
Onboard nextcloud (docs/13 row 7): public, DR-critical file sync backed by an external PostgreSQL. Establishes the reusable CNPG-DB pattern for later DB-backed services. - catalog/nextcloud.yaml: ServiceDefinition (image nextcloud:31-apache :80, public, internet, data 20Gi longhorn @/var/www/html, backup daily-offcluster, auth oidc +platform-admins, ingress nextcloud.home.keithjackson.dev, dependency nextcloud-db:5432). Uses schema 1.2.0 env for the Postgres connection, break-glass admin, trusted-domain + OVERWRITE* proxy settings. - apps/nextcloud-db.yaml: CloudNativePG Cluster in a dedicated nextcloud-db namespace (modeled on keycloak-db; no default-deny, mirroring the verified keycloak posture), inheritedMetadata stamps app.kubernetes.io/name=nextcloud-db so the rendered egress CNP matches. initdb consumes a pre-provisioned owner secret. - apps/nextcloud-db-app.sops.yaml + apps/nextcloud-bootstrap-secret.sops.yaml: SOPS (age) — shared DB password mirrored across the two namespaces (Pods cannot read a Secret cross-namespace), plus the break-glass local admin. - apps/nextcloud.yaml: rendered manifests (catalog/render.py --no-image-automation). - apps/kustomization.yaml: wire in the four new resources. OIDC realm-client wiring DEFERRED (WS-APPS step-3 escape hatch): editing the reconciled realm import in platform-config risks the running Keycloak realm / whole platform-config apply, and nextcloud OIDC needs post-install occ steps with no first-class env — nextcloud comes up INSTALLED on the break-glass local admin (as Gitea did); the Keycloak client is a follow-up. Off-cluster backup awaits Velero/OQ-BKP (intent declared). Gates: render --selftest PASS; other apps byte-identical; ci l0 17/17; l1 3/3; lint clean.
