.
Knative source
You can use the http-source
Kamelet as a Knative source by binding it to a Knative object.
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: http-source-binding
spec:
source:
ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1

sink:
ref:
kind: Channel
apiVersion: messaging.knative.dev/v1
name: mychannel
Prerequisite
You have Camel K installed on the cluster.
Procedure for using the cluster CLI
-
Save the
http-source-binding.yaml
file to your local drive, and then edit it as needed for your configuration. -
Run the source by using the following command:
kubectl apply -f http-source-binding.yaml
Procedure for using the Kamel CLI
Configure and run the source by using the following command:
kamel bind http-source -p "source.url=\https://gist.githubusercontent.com/nicolaferraro/e3c72ace3c751f9f88273896611ce5fe/raw/3b6f54060bacb56b6719b7386a4645cb59ad6cc1/quote.json" channel:mychannel
