Nothing enforced that spec.application.kind is unique, and each consumer that
maps a kind back to a definition resolved a duplicate its own way: the
chartRef reconciler let every definition rewrite every release of its kind,
the lineage webhook and the CA projection reconciler took whichever came
first in an unordered list, and cozystack-api registered one resource per
definition. A second definition declaring a kind already in use could
therefore repoint that kind's tenant releases at its own artifact.
Add one ownership rule, the definition created first owns the kind with ties
broken by name, and route every consumer through it. A definition that
arrives later with a kind already in use no longer manages that kind's
releases whatever it is named: the chartRef reconciler skips it with a
Warning event and re-reconciles the next owner when the current one goes,
cozystack-api registers the owner only and logs the rest, its restart hash
moves when ownership moves, and the lineage and CA projection lookups
resolve the owner.

Replace ingress-nginx as the default ingress layer for cozystack-native
services with Cilium Gateway API, materialised per-tenant via a new
TenantGateway CRD reconciled by cozystack-controller.
The extra/gateway chart renders one gateway.cozystack.io/v1alpha1
TenantGateway per tenant; the controller owns the resulting Gateway,
per-tenant Issuer, Certificate(s), and the http->https redirect
HTTPRoute. This avoids the helm-vs-controller race on
Gateway.spec.listeners when route-driven listeners are added.
publishing.certificates.solver selects HTTP-01 (default; per-app HTTPS
listener + per-app Certificate) or DNS-01 (opt-in; single wildcard
Certificate per apex; providers: cloudflare, route53, digitalocean,
rfc2136). HTTP-01 keeps zero-config per-app onboarding; DNS-01 saves
Let's Encrypt budget on apex-shared clusters.
Security model -- seven independent layers, all admission-time gates
fail-closed:
1. Listener allowedRoutes namespace whitelist via the
kube-apiserver-written kubernetes.io/metadata.name label;
plain-HTTP listener is strictly narrower than HTTPS, and HTTPS /
passthrough listeners restrict allowedRoutes.kinds to
HTTPRoute / TLSRoute respectively.
2. cozystack-gateway-hostname-policy VAP on Gateway.
3. cozystack-gateway-attached-namespaces-policy VAP on Package --
blocks tenant-* in gateway.attachedNamespaces.
4. cozystack-tenant-host-policy VAP on Tenant -- blocks spec.host
writes from non-trusted callers.
5. cozystack-namespace-host-label-policy VAP on Namespace -- blocks
writes to namespace.cozystack.io/host from non-trusted callers.
6. Render-time fail in cozystack-basics for tenant-* in
gateway.attachedNamespaces.
7. cozystack-route-hostname-policy VAP on HTTPRoute / TLSRoute,
scoped to tenant-* namespaces.
Within-apex cross-namespace hostname conflict is resolved at reconcile
time by a HostnameConflict condition (cozy-* namespace wins).
Five reconcile paths refuse to rewrite pre-existing objects with the
controller-derived name but no OwnerReference back to the
TenantGateway: Gateway, redirect HTTPRoute, per-tenant Issuer, wildcard
Certificate, per-listener Certificate.
Derived-apex tenants (tenants whose host is a subdomain of a parent
tenant's) auto-enable Gateway when the platform-level gateway.enabled
is on.
Bonus fix: pkg/registry/apps/application/rest.go was ignoring the
createValidation and deleteValidation callbacks that genericapiserver
hands to every storage method, silently bypassing admission for Create
and Delete on every apps.cozystack.io resource (Tenant, MariaDB,
Postgres, Kubernetes, ...). Aligned with the existing updateValidation
pattern.
Always-on changes: cilium.envoy.enabled + cilium.gatewayAPI.enabled
flip to true (extra cilium-envoy DaemonSet, ~100 MB RAM/node idle),
and the cozystack-api admission-chain fix. Everything else is gated
behind gateway.enabled=false and tenant.spec.gateway=false; existing
clusters see no behavioural change until an operator opts in.
Tests: 60+ Go cases in internal/controller/tenantgateway/, admission-
chain regression tests in pkg/registry/apps/application/, helm-unittest
across 7 charts (extra/gateway, core/platform, apps/tenant,
system/cozystack-basics, system/cert-manager-issuers,
system/cozystack-api, system/dashboard), and 14 e2e bats scenarios in
hack/e2e-apps/gateway.bats. New make test-controllers target wired
into pull-requests.yaml.
Deps: sigs.k8s.io/gateway-api v1.4.1, cert-manager v1.17.4.
