Chapter 15. Service Registry Operator configuration reference
This chapter provides detailed information on the custom resource used to configure the Service Registry Operator to deploy Service Registry:
15.1. Service Registry Custom Resource
The Service Registry Operator defines an ApicurioRegistry
custom resource (CR) that represents a single deployment of Service Registry on OpenShift.
These resource objects are created and maintained by users to instruct the Service Registry Operator how to deploy and configure Service Registry.
Example ApicurioRegistry CR
The following command displays the ApicurioRegistry
resource:
oc edit apicurioregistry example-apicurioregistry
apiVersion: apicur.io/v1alpha1 kind: ApicurioRegistry metadata: name: example-apicurioregistry namespace: demo-streams # ... spec: configuration: persistence: streams streams: bootstrapServers: 'my-cluster-kafka-bootstrap.demo-streams.svc:9092' deployment: host: >- example-apicurioregistry.demo-streams.example.com status: deploymentName: example-apicurioregistry-deployment-qsdb7 host: >- example-apicurioregistry.demo-streams.example.com image: >- registry.redhat.io/integration/service-registry-streams-rhel8@sha256:4b56da802333d2115cb3a0acc8d97445bd0dab67b639c361816df27b7f1aa296 ingressName: example-apicurioregistry-ingress-7mlnw replicaCount: 1 serviceName: example-apicurioregistry-service-xvnmz
The Service Registry Operator currently only watches its own project namespace. Therefore you must create the ApicurioRegistry
CR in the same namespace.

15.2. Service Registry CR spec
The spec
is the part of the ApicurioRegistry
CR that is used to provide the desired state or configuration for the Operator to achieve.
ApicurioRegistry CR spec contents
The following example block contains the full tree of possible spec
configuration options. Some fields may not be required or should not be defined at the same time.
spec: configuration: persistence: <string> dataSource: url: <string> userName: <string> password: <string> kafka: bootstrapServers: <string> streams: bootstrapServers: <string> applicationId: <string> applicationServerPort: <string> security: tls: truststoreSecretName: <string> keystoreSecretName: <string> scram: mechanism: <string> truststoreSecretName: <string> user: <string> passwordSecretName: <string> infinispan: clusterName: <string> ui: readOnly: <string> logLevel: <string> deployment: replicas: <int32> host: <string>
The following table describes each configuration option:
Configuration option | type | Default value | Description |
---|---|---|---|
| - | - | Section for configuration of Service Registry application |
| string |
|
Storage backend. One of |
| - | - | Database connection configuration for JPA storage backend |
| string | required | Database connection URL string |
| string | required | Database connection user |
| string | empty | Database connection password |
| - | - | Kafka Streams storage backend configuration |
| string | required | Kafka bootstrap server URL, for Streams storage backend |
| string | ApicurioRegistry CR name | Kafka Streams application ID |
| string |
| - |
| - | - | Section to configure TLS authentication for Kafka Streams storage backend |
| string | required | Name of a secret containing TLS truststore for Kafka |
| string | required | Name of a secret containing user TLS keystore |
| string | required | Name of a secret containing TLS truststore for Kafka |
| string | required | SCRAM user name |
| string | required | Name of a secret containing SCRAM user password |
| string |
| SASL mechanism |
| - | - | Infinispan persistence configuration section |
| string | ApicurioRegistry CR name | Infinispan cluster name |
| - | - | Service Registry web console settings |
| string |
| Set Service Registry web console to read-only mode |
| string |
|
Service Registry operand log level. One of |
| - | - | Section for operand deployment settings |
| positive integer |
| Number of Service Registry pods to deploy |
| string | auto-generated from ApicurioRegistry CR name and namespace | Host/URL where the Service Registry console and API are available |
If an option is marked as required, it might be conditional on other configuration options being enabled. Empty values might be accepted, but the Operator does not perform the specified action.
15.3. Service Registry CR status
The status
is the section of the CR managed by the Service Registry Operator that contains a description of the current deployment and application state.
ApicurioRegistry CR status contents
The status
section contains the following fields:
status: image: <string> deploymentName: <string> serviceName: <string> ingressName: <string> replicaCount: <int32> host: <string>
Status field | Type | Description |
---|---|---|
| string | Service Registry operand image that the Operator deploys. Might change based on the storage option selected in configuration. |
| string |
Name of the |
| string |
Name of the |
| string |
Name of the |
| int32 | Number of Service Registry operand pods deployed. |
| string | URL where the Service Registry UI and REST API are accessible. |
15.4. Service Registry managed resources
The resources managed by the Service Registry Operator when deploying Service Registry are as follows:
-
DeploymentConfig
-
Service
-
Ingress
-
Route
-
PodDisruptionBudget
15.5. Service Registry Operator labels
Resources managed by the Service Registry Operator are usually labeled as follows:
Label | Description |
---|---|
|
Name of the Service Registry deployment that the resource belongs to, based on the name of the specified |
|
Type of the deployment: |
|
Name of the deployment: same value as |
| Version of the Service Registry or the Service Registry Operator |
| A set of recommended Kubernetes labels for application deployments. |
| Metering labels for Red Hat products. |
