kn-source-kamelet Knative eventing sources plugin manages Kamelet event sources on your cluster.

Description

With this plugin, you can list available [Kamelets](https://github.com/apache/camel-kamelets) and bindings on your cluster. Kamelets can act as Knative eventing sources where each binding connects a Kamelet source to a Knative sink (broker, channel, service).

  kn-source-kamelet [command]

Available Commands:
  bind          Create Kamelet bindings and bind source to Knative broker, channel or service.
  binding       Configure and manage a Kamelet binding.
