Usage

This section describes how you can use the google-functions-sink.

Knative sink

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

google-functions-sink-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: google-functions-sink-binding
spec:
  source:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel
  sink:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: google-functions-sink
    properties:
      functionName: The Function Name
      projectId: The Project Id
      region: The Region
      serviceAccountKey: The Service Account Key

Prerequisite

You have Camel K installed on the cluster.

Procedure for using the cluster CLI

  1. Save the google-functions-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:

    kubectl apply -f google-functions-sink-binding.yaml

Procedure for using the Kamel CLI

Configure and run the sink by using the following command:

kamel bind google-functions-sink -p "sink.functionName=The Function Name" -p "sink.projectId=The Project Id" -p "sink.region=The Region" -p "sink.serviceAccountKey=The Service Account Key" channel:mychannel

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