Service Integrations

Service Integrations provide additional functionality and features by connecting different Aiven services together.

See our Getting Started with Service Integrations guide for more information.

Prerequisites

Send Kafka logs to a Kafka Topic

This integration allows you to send Kafka service logs to a specific Kafka Topic.

First, let's create a Kafka service and a topic.

1. Create a new file named kafka-sample-topic.yaml with the following content:

apiVersion: aiven.io/v1alpha1
kind: Kafka
metadata:
  name: kafka-sample
spec:
  # gets the authentication token from the `aiven-token` Secret
  authSecretRef:
    name: aiven-token
    key: token

  # outputs the Kafka connection on the `kafka-connection` Secret
  connInfoSecretTarget:
    name: kafka-auth

  # add your Project name here
  project: PROJECT_NAME

  # cloud provider and plan of your choice
  # you can check all of the possibilities here https://aiven.io/pricing
  cloudName: google-europe-west1
  plan: startup-2

  # general Aiven configuration
  maintenanceWindowDow: friday
  maintenanceWindowTime: 23:00:00

  # specific Kafka configuration
  userConfig:
    kafka_version: "2.7"

---
apiVersion: aiven.io/v1alpha1
kind: KafkaTopic
metadata:
  name: logs
spec:
  authSecretRef:
    name: aiven-token
    key: token

  project: PROJECT_NAME
  serviceName: kafka-sample

  # here we can specify how many partitions the topic should have
  partitions: 3
  # and the topic replication factor
  replication: 2

  # we also support various topic-specific configurations
  config:
    flush_ms: 100

2. Create the resource on Kubernetes:

kubectl apply -f kafka-sample-topic.yaml

3. Now, create a ServiceIntegration resource to send the Kafka logs to the created topic. In the same file, add the following YAML:

apiVersion: aiven.io/v1alpha1
kind: ServiceIntegration
metadata:
  name: service-integration-kafka-logs
spec:
  # gets the authentication token from the `aiven-token` Secret
  authSecretRef:
    name: aiven-token
    key: token

  project: PROJECT_NAME

  # indicates the type of the integration
  integrationType: kafka_logs

  # we will send the logs to the same kafka-sample instance
  # the source and destination are the same
  sourceServiceName: kafka-sample
  destinationServiceName: kafka-sample

  # the topic name we will send to
  kafkaLogs:
    kafka_topic: logs

4. Reapply the resource on Kubernetes:

kubectl apply -f kafka-sample-topic.yaml

5. Let's check the created service integration:

kubectl get serviceintegrations.aiven.io service-integration-kafka-logs

The output is similar to the following:

NAME                             PROJECT        TYPE         SOURCE SERVICE NAME   DESTINATION SERVICE NAME   SOURCE ENDPOINT ID   DESTINATION ENDPOINT ID
service-integration-kafka-logs   your-project   kafka_logs   kafka-sample          kafka-sample

Your Kafka service logs are now being streamed to the logs Kafka topic.
