22.3. Usage
This section describes how you can use the http-sink.
22.3.1. Knative Sink
You can use the http-sink Kamelet as a Knative sink by binding it to a Knative object.
http-sink-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: http-sink-binding
spec:
source:
ref:
kind: Channel
apiVersion: messaging.knative.dev/v1
name: mychannel
sink:
ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: http-sink
properties:
url: "https://my-service/path"
22.3.1.1. Prerequisite
Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.
22.3.1.2. Procedure for using the cluster CLI
-
Save the
http-sink-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the sink by using the following command:
oc apply -f http-sink-binding.yaml
22.3.1.3. Procedure for using the Kamel CLI
Configure and run the sink by using the following command:
kamel bind channel:mychannel http-sink -p "sink.url=https://my-service/path"
This command creates the KameletBinding in the current namespace on the cluster.
22.3.2. Kafka Sink
You can use the http-sink Kamelet as a Kafka sink by binding it to a Kafka topic.
http-sink-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: http-sink-binding
spec:
source:
ref:
kind: KafkaTopic
apiVersion: kafka.strimzi.io/v1beta1
name: my-topic
sink:
ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: http-sink
properties:
url: "https://my-service/path"
22.3.2.1. Prerequisites
Ensure that you’ve installed the AMQ Streams operator in your OpenShift cluster and created a topic named my-topic in the current namespace. Make also sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.
22.3.2.2. Procedure for using the cluster CLI
-
Save the
http-sink-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the sink by using the following command:
oc apply -f http-sink-binding.yaml
22.3.2.3. Procedure for using the Kamel CLI
Configure and run the sink by using the following command:
kamel bind kafka.strimzi.io/v1beta1:KafkaTopic:my-topic http-sink -p "sink.url=https://my-service/path"
This command creates the KameletBinding in the current namespace on the cluster.
