Setup Kafka

{{< tabs "Self-Hosted" "Kubernetes">}}

{{% codetab %}} You can run Kafka locally using this Docker image. To run without Docker, see the getting started guide here. {{% /codetab %}}

{{% codetab %}} To run Kafka on Kubernetes, you can use the Helm Chart. {{% /codetab %}}

{{< /tabs >}}

Create a Dapr component

The next step is to create a Dapr component for Kafka.

Create the following YAML file named kafka.yaml:

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <NAME>
  namespace: <NAMESPACE>
spec:
  type: pubsub.kafka
  version: v1
  metadata:
      # Kafka broker connection setting
    - name: brokers
      # Comma separated list of kafka brokers
      value: "dapr-kafka.dapr-tests.svc.cluster.local:9092"
      # Enable auth. Default is "false"
    - name: authRequired
      value: "false"
      # Only available is authRequired is set to true
    - name: saslUsername
      value: <username>
      # Only available is authRequired is set to true
    - name: saslPassword
      value: <password>

{{% alert title="Warning" color="warning" %}} The above example uses secrets as plain strings. It is recommended to use a secret store for the secrets as described [here]({{< ref component-secrets.md >}}). {{% /alert %}}
