Edge + serverless + model-serving batch (W2.5.C) — three upstream-
subchart umbrella Blueprints completing the bootstrap-kit slots for
WebRTC media relay (bp-relay → bp-stunner) and the AI/ML serving stack
(bp-cortex → bp-kserve → bp-knative).
Each chart follows the canonical umbrella pattern from
docs/BLUEPRINT-AUTHORING.md §11.1: Chart.yaml declares the upstream
chart under `dependencies:` so `helm dependency build` bundles the
upstream payload into the OCI artifact, and Catalyst-curated overlay
values + templates sit alongside in chart/values.yaml + chart/templates/.
Per-chart highlights:
- bp-stunner/1.0.0 — wraps stunner/stunner-gateway-operator 1.1.0.
Ships a Cilium-native GatewayClass (Capabilities-gated on
gateway.networking.k8s.io/v1) so bp-relay (LiveKit / SFU) can claim
Gateway CRs without an operator-ordering dance. Default UDP TURN port
range 30000-32767 matches the range opened at the Sovereign edge
firewall (Crossplane bp-firewall composition).
- bp-knative/1.0.0 — wraps knative-operator v1.21.1. Ships a
KnativeServing CR pre-configured for **istio-less mode**
(ingress.istio.enabled=false, ingress.contour.enabled=false,
ingress.kourier.enabled=false; config.network.ingress-class=cilium).
Sovereign FQDN sourced from values, no hardcoded fallback per
inviolable principle #4 — render fails loudly if cluster overlay
doesn't set knativeOverlay.knativeServing.sovereignFqdn.
- bp-kserve/1.0.0 — wraps kserve/kserve v0.16.0 (latest version
published on the official OCI registry as of 2026-04-30). Default
deploymentMode=RawDeployment (no Knative hop on the hot path) but
bp-knative is still installed (declared as a hard dep) so per-IS
annotation `serving.kserve.io/deploymentMode: Serverless` opts in to
scale-to-zero per tenant. Cilium native Gateway-API ingress
(enableGatewayApi=true, className=cilium, disableIstioVirtualHost=
true).
Observability discipline (issue #182): every observability toggle
(ServiceMonitor, HPA, GatewayClass) defaults false and is operator-
tunable via per-cluster overlay once bp-kube-prometheus-stack reconciles.
Each chart ships tests/observability-toggle.sh covering default-off,
opt-in (with `--api-versions monitoring.coreos.com/v1` to simulate
Prometheus Operator CRDs), and explicit-off cases.
Per-chart kind summary (helm template default render):
bp-stunner: ClusterRole, ClusterRoleBinding, ConfigMap, Dataplane,
Deployment, Role, RoleBinding, Service, ServiceAccount.
(+ GatewayClass when --api-versions
gateway.networking.k8s.io/v1 is passed.)
bp-knative: ClusterRole, ClusterRoleBinding, ConfigMap,
CustomResourceDefinition, Deployment, KnativeServing,
Role, RoleBinding, Secret, Service, ServiceAccount.
bp-kserve: Certificate, ClusterRole, ClusterRoleBinding,
ClusterServingRuntime, ClusterStorageContainer,
ConfigMap, Deployment, Gateway, Issuer,
MutatingWebhookConfiguration, Role, RoleBinding,
Service, ServiceAccount, ValidatingWebhookConfiguration.
`helm lint` clean for all three (single INFO on missing icon — icons
land with marketplace card work).
`bash tests/observability-toggle.sh` green for all three (3 cases each:
default-off, opt-in, explicit-off).
