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

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