5.3. Usage
Copy link

This section describes how you can use the aws-lambda-sink.

5.3.1. Knative Sink
Copy link

You can use the aws-lambda-sink Kamelet as a Knative sink by binding it to a Knative object.

aws-lambda-sink-binding.yaml

apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: aws-lambda-sink-binding
spec:
  source:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel
  sink:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: aws-lambda-sink
    properties:
      accessKey: "The Access Key"
      function: "The Function Name"
      region: "eu-west-1"
      secretKey: "The Secret Key"
Copy to Clipboard Toggle word wrap

5.3.1.1. Prerequisite
Copy link

Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.

5.3.1.2. Procedure for using the cluster CLI
Copy link

  1. Save the aws-lambda-sink-binding.yaml file to your local drive, and then edit it as needed for your configuration.

  2. Run the sink by using the following command: 

    oc apply -f aws-lambda-sink-binding.yaml
    Copy to Clipboard Toggle word wrap

5.3.1.3. Procedure for using the Kamel CLI
Copy link

Configure and run the sink by using the following command: 

kamel bind channel:mychannel aws-lambda-sink -p "sink.accessKey=The Access Key" -p "sink.function=The Function Name" -p "sink.region=eu-west-1" -p "sink.secretKey=The Secret Key"
Copy to Clipboard Toggle word wrap

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

5.3.2. Kafka Sink
Copy link

You can use the aws-lambda-sink Kamelet as a Kafka sink by binding it to a Kafka topic.

aws-lambda-sink-binding.yaml

apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: aws-lambda-sink-binding
spec:
  source:
    ref:
      kind: KafkaTopic
      apiVersion: kafka.strimzi.io/v1beta1
      name: my-topic
  sink:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: aws-lambda-sink
    properties:
      accessKey: "The Access Key"
      function: "The Function Name"
      region: "eu-west-1"
      secretKey: "The Secret Key"
Copy to Clipboard Toggle word wrap

5.3.2.1. Prerequisites
Copy link

Ensure that you’ve installed the AMQ Streams operator in your OpenShift cluster and created a topic named my-topic in the current namespace. Make also sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.

5.3.2.2. Procedure for using the cluster CLI
Copy link

  1. Save the aws-lambda-sink-binding.yaml file to your local drive, and then edit it as needed for your configuration.

  2. Run the sink by using the following command: 

    oc apply -f aws-lambda-sink-binding.yaml
    Copy to Clipboard Toggle word wrap

5.3.2.3. Procedure for using the Kamel CLI
Copy link

Configure and run the sink by using the following command: 

kamel bind kafka.strimzi.io/v1beta1:KafkaTopic:my-topic aws-lambda-sink -p "sink.accessKey=The Access Key" -p "sink.function=The Function Name" -p "sink.region=eu-west-1" -p "sink.secretKey=The Secret Key"
Copy to Clipboard Toggle word wrap

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