Role and responsibilities
Issues and renews TLS certificates for ingress and internal services.
Data model
Tables (schema eai, every tenant table carries tenant_id uuid NOT NULL with an RLS policy on current_setting('app.tenant_id', true)::uuid): eai.schema_migrations, eai.audit_events.
API endpoints
This brick has no dedicated Control Plane endpoint; it is operated through Helm/GitOps and observed through GET /healthz and telemetry.
SDK usage
Python (enterprise_ai):
from enterprise_ai import EnterpriseAI
client = EnterpriseAI(base_url="<control-plane-url>", api_key="eai_xxx_secret")
items = client.system.meta()
TypeScript (@enterprise-ai/sdk):
import { EnterpriseAI } from "@enterprise-ai/sdk";
const eai = new EnterpriseAI({ baseUrl: "<control-plane-url>", apiKey: process.env.EAI_API_KEY });
const items = await eai.meta.get();
Java (enterprise-ai-java):
EnterpriseAIClient client = EnterpriseAIClient.builder()
.baseUrl("<control-plane-url>")
.apiKey(System.getenv("EAI_API_KEY"))
.build();
var items = client.meta().get();
Go (enterprise-ai-go):
client, _ := eai.NewClient(eai.WithBaseURL("<control-plane-url>"), eai.WithAPIKey(os.Getenv("EAI_API_KEY")))
items, err := client.Meta.Get(ctx)
Configuration
- Environment:
EAI_DATABASE_URL,EAI_OTEL_EXPORTER_OTLP_ENDPOINT. - Helm values:
cert-manager.enabled,cert-manager.replicas,cert-manager.resources.
Security controls
- Authentication by OIDC JWT, tenant API key with scopes, or SPIFFE mTLS; tenant resolved from the credential, never from the body.
- Authorization through OpenFGA and OPA decisions; every mutation and decision writes a hash-chained
eai.audit_eventsrow. - Secrets never returned by the API; TLS everywhere; Cilium network policies restrict who can reach the service.
Observability
- Metrics:
eai_certificates_requests_total,eai_certificates_errors_total,eai_certificates_latency_seconds(Prometheus). - Traces: OpenTelemetry spans
eai.meta.*with W3Ctraceparentpropagation, AI spans forwarded to Opik. - Audit actions:
manifest.apply,audit.export,policy.evaluate.
FinOps aspects
Operating cost is allocated per tenant and project through labels on Usage Events and Kubernetes resource requests; no direct per-call cost.
Failure modes and resilience
- Stateless replicas behind the API Gateway, PostgreSQL HA for state; readiness probe
GET /readyzremoves unhealthy pods. - External system unavailable: fail closed for security decisions, explicit error code, no silent bypass.
Standalone adoption (client of a client)
A client of a client can adopt this brick alone with the Python SDK sub-client client.system (TS eai.meta, Java client.system.meta(), Go client.Meta). Minimal deployment: Control Plane API + PostgreSQL + Keycloak (or API keys), the Control Plane loads every domain of services/control-plane/src/eai/domains; the optional chart components are switched off in deploy/helm/enterprise-ai/values.yaml (vllm.enabled, qdrant.enabled, nats.enabled, workers.enabled).
Acceptance tests
- A tenant cannot read or modify another tenant's resources (RLS test).
- Every mutation produces an audit event verifiable by
GET /v1/audit/verify. - Errors are returned in English and French according to
Accept-Language.
