jakman85andClaude Opus 4.8 7f92adfac6 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).

apps

App-tier manifests, rendered from catalog/*.yaml ServiceDefinitions by catalog/render.py and split into dependency-ordered waves (wave-<N>/).

  • Each wave-<N>/ is reconciled by its own Flux Kustomization apps-wave-<N> (clusters/base/apps-wave-<N>.yaml), which dependsOn wave N-1 (wave 0 dependsOn platform-config) and health-gates (wait: true) ONLY that wave. A crashlooping workload in a later wave can no longer stall an earlier wave or block new revisions.
  • wave-<N>/kustomization.yaml and clusters/base/apps-wave-<N>.yaml are generated — run python3 catalog/render.py --emit-waves after onboarding a service; do not hand-edit them.
  • Wave assignment = longest dependency-path depth over the catalog dependencies: graph; a co-located CNPG database <svc>-db is a leaf and always lands strictly below its consumer.

See ../DESIGN-waves.md for the wave table, Flux topology, and the cutover runbook.
