Usage

This section summarizes how the aws-cloudwatch-sink can be used in various contexts.

Knative Sink

The aws-cloudwatch-sink Kamelet can be used as Knative sink by binding it to a Knative object.

aws-cloudwatch-sink-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: aws-cloudwatch-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-cloudwatch-sink
    properties:
      accessKey: "The Access Key"
      cw_namespace: "The Cloud Watch Namespace"
      region: "eu-west-1"
      secretKey: "The Secret Key"

Make sure you have Camel K installed into the Kubernetes cluster you’re connected to.

Save the aws-cloudwatch-sink-binding.yaml file into your hard drive, then configure it according to your needs.

You can run the sink using the following command:

kubectl apply -f aws-cloudwatch-sink-binding.yaml

Dependencies

The Kamelet needs the following dependencies:

  • camel:aws2-cw

  • camel:kamelet

Binding to Knative using the Kamel CLI:

The procedure described above can be simplified into a single execution of the kamel bind command:

kamel bind channel:mychannel aws-cloudwatch-sink -p "sink.accessKey=The Access Key" -p "sink.cw_namespace=The Cloud Watch Namespace" -p "sink.region=eu-west-1" -p "sink.secretKey=The Secret Key"

This will create the KameletBinding under the hood and apply it to the current namespace in the cluster.

Kafka Sink

The aws-cloudwatch-sink Kamelet can be used as Kafka sink by binding it to a Kafka topic.

aws-cloudwatch-sink-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: aws-cloudwatch-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-cloudwatch-sink
    properties:
      accessKey: "The Access Key"
      cw_namespace: "The Cloud Watch Namespace"
      region: "eu-west-1"
      secretKey: "The Secret Key"

Ensure that you’ve installed Strimzi and created a topic named my-topic in the current namespace. Make also sure you have Camel K installed into the Kubernetes cluster you’re connected to.

Save the aws-cloudwatch-sink-binding.yaml file into your hard drive, then configure it according to your needs.

You can run the sink using the following command:

kubectl apply -f aws-cloudwatch-sink-binding.yaml

Binding to Kafka using the Kamel CLI:

The procedure described above can be simplified into a single execution of the kamel bind command:

kamel bind kafka.strimzi.io/v1beta1:KafkaTopic:my-topic aws-cloudwatch-sink -p "sink.accessKey=The Access Key" -p "sink.cw_namespace=The Cloud Watch Namespace" -p "sink.region=eu-west-1" -p "sink.secretKey=The Secret Key"

This will create the KameletBinding under the hood and apply it to the current namespace in the cluster.
