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.

# Nextcloud's PostgreSQL — a CloudNativePG Cluster (CR of the CNPG CRDs from platform/cnpg), modeled
|
|
# on platform/keycloak/postgres-cluster.yaml. This is the first CNPG-DB in apps/ and establishes the
|
|
# reusable pattern for later DB-backed services (semaphore, unifi, ...).
|
|
#
|
|
# WHY A DEDICATED `nextcloud-db` NAMESPACE (not co-located in `nextcloud`):
|
|
# The app->db edge in catalog/nextcloud.yaml (`dependencies: to: nextcloud-db`) compiles to a
|
|
# CiliumNetworkPolicy whose egress selector pins BOTH the destination pod label
|
|
# (app.kubernetes.io/name=nextcloud-db) AND its namespace (k8s:io.kubernetes.pod.namespace=
|
|
# nextcloud-db) — cross-namespace Cilium selectors must name the namespace (catalog/render.py
|
|
# r_dependency_policies). So the DB MUST live in a namespace literally named `nextcloud-db` and its
|
|
# pods MUST carry app.kubernetes.io/name=nextcloud-db, injected below via inheritedMetadata.
|
|
#
|
|
# DEFAULT-DENY POSTURE — mirrors keycloak (platform/keycloak/namespace.yaml): this namespace is
|
|
# INTENTIONALLY not homelab.keithjackson.dev/app-namespace=true, so Kyverno does NOT generate the app
|
|
# default-deny baseline here and CNPG runs under Cilium's cluster-wide default-allow — the SAME posture
|
|
# the verified keycloak-db uses. The nextcloud SIDE keeps its default-deny; its rendered egress-allow
|
|
# opens ONLY nextcloud -> nextcloud-db:5432, and the DB side's default-allow accepts that reciprocal
|
|
# ingress. No app-namespace policy (auth-mode/host-namespace/secret-provenance) is weakened.
