Discovery

The Stackable Operator for Apache Kafka publishes a service discovery ConfigMap which exposes a client configuration bundle that allows access to the Apache Kafka cluster.

The bundle includes a thrift connection string to access the Kafka broker service. This string may be used by other operators or tools to configure their products with access to Kafka. This is limited to internal cluster access.

Example

Given the following Kafka cluster:

apiVersion: kafka.stackable.tech/v1alpha1
kind: KafkaCluster
metadata:
  name: simple-kafka  (1)
  namespace: stackable (2)
spec:
  […]

1	The name of the Kafka cluster, which is also the name of the created discovery ConfigMap.
2	The namespace of the discovery ConfigMap.

The resulting discovery ConfigMap is stackable/simple-kafka.

The stackable/simple-kafka discovery ConfigMap contains the following fields where simple-kafka represents the name and stackable the namespace of the cluster:

KAFKA

Contains the thrift protocol connection string for the Kafka cluster:

simple-kafka.stackable.svc.cluster.local:9092
