Usage

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

Knative Source

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

http-secured-source-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: http-secured-source-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: http-secured-source
    properties:
      url: "https://gist.githubusercontent.com/nicolaferraro/e3c72ace3c751f9f88273896611ce5fe/raw/3b6f54060bacb56b6719b7386a4645cb59ad6cc1/quote.json"
  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 http-secured-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 http-secured-source-binding.yaml

Dependencies

The Kamelet needs the following dependencies:

  • camel:http

  • camel:kamelet

  • camel:core

  • camel:timer

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 http-secured-source -p "source.url=https://gist.githubusercontent.com/nicolaferraro/e3c72ace3c751f9f88273896611ce5fe/raw/3b6f54060bacb56b6719b7386a4645cb59ad6cc1/quote.json" channel:mychannel

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

Kafka Source

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

http-secured-source-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: http-secured-source-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: http-secured-source
    properties:
      url: "https://gist.githubusercontent.com/nicolaferraro/e3c72ace3c751f9f88273896611ce5fe/raw/3b6f54060bacb56b6719b7386a4645cb59ad6cc1/quote.json"
  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 http-secured-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 http-secured-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 http-secured-source -p "source.url=https://gist.githubusercontent.com/nicolaferraro/e3c72ace3c751f9f88273896611ce5fe/raw/3b6f54060bacb56b6719b7386a4645cb59ad6cc1/quote.json" 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.
