Data Services Naming Standards

Purpose: For platform engineers and contributors, provides the canonical naming conventions for all data services artifacts.

Product Names

Context	Name	Notes
Marketing / docs	openCenter Managed Kafka	Title case, full product name
CLI output	managed-kafka	Kebab-case
Conversation	"managed Kafka" or "the Kafka service"	Informal

Apply the same pattern for future services: openCenter Managed PostgreSQL, openCenter Managed Redis, etc.

Blueprint Names

Convention	Example
Blueprint directory	managed-kafka-v1
FluxCD Kustomization	managed-kafka
Git tag	managed-kafka-v1.0.0

Namespace Conventions

Service	Namespace	Rationale
Kafka operator	data-kafka	data- prefix groups all data services
Kafka clusters	data-kafka	Co-located with operator
PostgreSQL operator	data-postgres	Same prefix pattern
PostgreSQL clusters	data-postgres	Co-located with operator
Schema Registry	data-kafka	Kafka add-on, same namespace
CDC (Debezium)	data-kafka	Runs as KafkaConnect, same namespace

CRD Naming

API group: data.opencenter.cloud

CRD	Kind	Plural
DataService	DataService	dataservices
DataServiceTopic	DataServiceTopic	dataservicetopics
DataServiceUser	DataServiceUser	dataserviceusers
DataServiceConnector	DataServiceConnector	dataserviceconnectors
OperationRun	OperationRun	operationruns
ProviderCapability	ProviderCapability	providercapabilities

Resource Naming Patterns

Resource Type	Pattern	Example
Kafka cluster	<customer>-<env>	acme-production
Kafka topic	<domain>.<entity>.<event>	payments.order.created
Kafka user	svc-<service-name>	svc-payment-processor
KafkaConnect	<cluster>-connect	acme-production-connect
PostgreSQL cluster	<customer>-<env>-pg	acme-production-pg

Repository Structure

            └── users/

FluxCD Naming

Resource	Name Pattern
GitRepository (base)	opencenter-strimzi-kafka-operator
Kustomization (operator)	strimzi-kafka-operator
Kustomization (instance)	managed-kafka-<cluster-name>

Helm Release Naming

Release	Chart	Namespace
strimzi-kafka-operator	strimzi-kafka-operator	data-kafka
kube-prometheus-stack	kube-prometheus-stack	observability

Image Tag Patterns

Component	Registry	Tag Pattern
Strimzi Operator	quay.io/strimzi/operator	0.44.0
Kafka	quay.io/strimzi/kafka	0.44.0-kafka-3.8.1
Kafka Bridge	quay.io/strimzi/kafka-bridge	0.30.0

Note: Versions above reflect the current gitops-base target. The streaming blueprint documents the latest supported versions. Always check openCenter-gitops-base for the pinned version in production.
