Accessing Services

StreamsHub Console #

Ingress Access #

For the Console to startup correctly and be accessible, you need an Ingress controller running in your cluster.

minikube #

Enable the ingress addon (if not already enabled):

minikube addons enable ingress

Use port-forwarding to access the console:

kubectl port-forward -n streamshub-console svc/streamshub-console-console-service 8090:80

Open http://localhost:8090 in your browser.

KIND #

If you created your KIND cluster with the port mappings described in Prerequisites, and deployed ingress-nginx: Use port-forwarding to access the console:

kubectl port-forward -n streamshub-console svc/streamshub-console-console-service 8090:80

Open http://localhost:8090 in your browser.

Kafka #

The Kafka cluster is accessible within the Kubernetes cluster at:

dev-cluster-kafka-bootstrap.kafka.svc.cluster.local:9092

Port-Forwarding #

To access Kafka from outside the cluster:

kubectl port-forward -n kafka svc/dev-cluster-kafka-bootstrap 9092:9092

Then connect your client to localhost:9092.

Producing and Consuming Messages #

From within the cluster, you can use the Kafka CLI tools:

# Start a producer
kubectl run kafka-producer -it --rm --image=quay.io/strimzi/kafka:0.51.0-kafka-4.2.0 \
  --restart=Never -- bin/kafka-console-producer.sh \
  --bootstrap-server dev-cluster-kafka-bootstrap.kafka.svc.cluster.local:9092 \
  --topic test

# Start a consumer (in a separate terminal)
kubectl run kafka-consumer -it --rm --image=quay.io/strimzi/kafka:0.51.0-kafka-4.2.0 \
  --restart=Never -- bin/kafka-console-consumer.sh \
  --bootstrap-server dev-cluster-kafka-bootstrap.kafka.svc.cluster.local:9092 \
  --topic test --from-beginning

Apicurio Registry #

The registry has two services accessible within the cluster:

• API: apicurio-registry-app-service.apicurio-registry.svc.cluster.local:8080
• UI: apicurio-registry-ui-service.apicurio-registry.svc.cluster.local:8080

Port-Forwarding #

The UI is a browser application that connects to the API backend at localhost:8080 by default. To use the UI, you must port-forward both the API and UI services.

API #

The API service must be forwarded to port 8080 for the UI to function:

kubectl port-forward -n apicurio-registry svc/apicurio-registry-app-service 8080:8080

You can query the API directly:

curl http://localhost:8080/apis/registry/v3/search/artifacts

UI #

In a separate terminal, forward the UI service:

kubectl port-forward -n apicurio-registry svc/apicurio-registry-ui-service 8081:8080

Open http://localhost:8081 in your browser.

Overlay Services #

If you installed with an overlay, it may deploy additional services. See the specific overlay page under Overlays for access instructions.
