Usage

This section describes how you can use the kafka-not-secured-source.

Knative source

You can use the kafka-not-secured-source Kamelet as a Knative source by binding it to a Knative object.

kafka-not-secured-source-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: kafka-not-secured-source-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: kafka-not-secured-source
    properties:
      bootstrapServers: The Bootstrap Servers
      topic: The Topic Names
  sink:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel

Prerequisite

You have Camel K installed on the cluster.

Procedure for using the cluster CLI

  1. Save the kafka-not-secured-source-binding.yaml file to your local drive, and then edit it as needed for your configuration.

  2. Run the source by using the following command:

    kubectl apply -f kafka-not-secured-source-binding.yaml

Procedure for using the Kamel CLI

Configure and run the source by using the following command:

kamel bind kafka-not-secured-source -p "source.bootstrapServers=The Bootstrap Servers" -p "source.topic=The Topic Names" channel:mychannel

This command creates the KameletBinding in the current namespace on the cluster.
