camel run route.yaml

Camel K Environment Usage

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

Knative sink

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

google-pubsub-sink-pipe.yaml
apiVersion: camel.apache.org/v1
kind: Pipe
metadata:
  name: google-pubsub-sink-pipe
spec:
  source:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel
  sink:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: google-pubsub-sink
    properties:
      destinationName: The Destination Name
      projectId: The Project Id

Prerequisite

You have Camel K installed on the cluster.

Procedure for using the cluster CLI

  1. Save the google-pubsub-sink-pipe.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-pubsub-sink-pipe.yaml

Procedure for using the Kamel CLI

Configure and run the sink by using the following command:

kamel bind channel:mychannel -p "sink.destinationName=The Destination Name" -p "sink.projectId=The Project Id" google-pubsub-sink

This command creates the Kamelet Pipe in the current namespace on the cluster.

Kafka sink

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

google-pubsub-sink-pipe.yaml
apiVersion: camel.apache.org/v1
kind: Pipe
metadata:

spec:
  source:
    ref:
      kind: KafkaTopic
      apiVersion: kafka.strimzi.io/v1beta1
      name: my-topic

  • You’ve installed Strimzi.

  • You’ve created a topic named my-topic in the current namespace.

  • You have Camel K installed on the cluster.

Procedure for using the cluster CLI

  1. Save the google-pubsub-sink-pipe.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-pubsub-sink-pipe.yaml
