Knative Sink

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

log-sink-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: log-sink-binding
spec:
  source:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel
  sink:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: log-sink

Prerequisite

You have Camel K installed on the cluster.

  2. Run the sink by using the following command:

    kubectl apply -f log-sink-binding.yaml

Procedure for using the Kamel CLI

Configure and run the sink by using the following command:

kamel bind channel:mychannel log-sink

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