webhook source Webhook Source

Provided by: "Apache Software Foundation"

Support Level for this Kamelet is: "Preview"

Creates an HTTP endpoint that can be used as a bridge to forward data to the Kamelet sink.

The "subpath" parameter of the Webhook source allows to customize the subpath where the integration will respond to HTTP requests. It’s common to use a non-guessable ID for that parameter.

When the "subpath" parameter is set to "webhook" (default), the integration will accept requests at the "https://integration-external-url/webhook" endpoint.

Usage

This section summarizes how the webhook-source can be used in various contexts.

Knative Source

The webhook-source Kamelet can be used as Knative source by binding it to a Knative object.

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

Make sure you have Camel K installed into the Kubernetes cluster you’re connected to.

Save the webhook-source-binding.yaml file into your hard drive, then configure it according to your needs.

You can run the source using the following command:

kubectl apply -f webhook-source-binding.yaml

Dependencies

The Kamelet needs the following dependencies:

  • camel:platform-http

  • camel:kamelet

Binding to Knative using the Kamel CLI:

The procedure described above can be simplified into a single execution of the kamel bind command:

kamel bind webhook-source channel:mychannel

This will create the KameletBinding under the hood and apply it to the current namespace in the cluster.

Kafka Source

The webhook-source Kamelet can be used as Kafka source by binding it to a Kafka topic.

webhook-source-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: webhook-source-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: webhook-source
  sink:
    ref:
      kind: KafkaTopic
      apiVersion: kafka.strimzi.io/v1beta1
      name: my-topic

Ensure that you’ve installed Strimzi and created a topic named my-topic in the current namespace. Make also sure you have Camel K installed into the Kubernetes cluster you’re connected to.

Save the webhook-source-binding.yaml file into your hard drive, then configure it according to your needs.

You can run the source using the following command:

kubectl apply -f webhook-source-binding.yaml

Binding to Kafka using the Kamel CLI:

The procedure described above can be simplified into a single execution of the kamel bind command:

kamel bind webhook-source kafka.strimzi.io/v1beta1:KafkaTopic:my-topic

This will create the KameletBinding under the hood and apply it to the current namespace in the cluster.
