Accessing topics from an application outside NAIS¶

This guide will show you how to access a Kafka topic from an application outside NAIS clusters.

Enable access to the relevant pool in your manifest¶

.nais/aivenapp.yaml

apiVersion: aiven.nais.io/v1
kind: AivenApplication
metadata:
  name: <MY-APP>
  namespace: <MY-TEAM>
spec:
  kafka:
    pool: <MY-POOL> (TODO: link to available tenant pools)
  secretName: <MY-UNIQUE-SECRET-NAME>
  protected: true

Info

The secretName must be a valid DNS label, and must be unique within the namespace.

Apply the AivenApplication¶

AutomaticallyManually

Add the file to your application repository, alongside nais.yaml to deploy with NAIS github action.

kubectl apply -f ./nais/aivenapp.yaml --namespace=<MY-TEAM> --context=<MY-ENV>

Extract the value of the generated secret¶

kubectl get secret <MY-UNIQUE-SECRET-NAME> --namespace <MY-TEAM> --contect <MY-ENV> -o jsonpath='{.data}'

Make the values available to your application.

Grant access to the topic¶

The owner of the topic must grant your application access to the topic.
