66.3. Usage
This section describes how you can use the slack-source.
66.3.1. Knative Source
You can use the slack-source Kamelet as a Knative source by binding it to a Knative object.
slack-source-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: slack-source-binding
spec:
source:
ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: slack-source
properties:
channel: "#myroom"
token: "The Token"
sink:
ref:
kind: Channel
apiVersion: messaging.knative.dev/v1
name: mychannel
66.3.1.1. Prerequisite
Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.
66.3.1.2. Procedure for using the cluster CLI
-
Save the
slack-source-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the source by using the following command:
oc apply -f slack-source-binding.yaml
66.3.1.3. Procedure for using the Kamel CLI
Configure and run the source by using the following command:
kamel bind slack-source -p "source.channel=#myroom" -p "source.token=The Token" channel:mychannel
This command creates the KameletBinding in the current namespace on the cluster.
66.3.2. Kafka Source
You can use the slack-source Kamelet as a Kafka source by binding it to a Kafka topic.
slack-source-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: slack-source-binding
spec:
source:
ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: slack-source
properties:
channel: "#myroom"
token: "The Token"
sink:
ref:
kind: KafkaTopic
apiVersion: kafka.strimzi.io/v1beta1
name: my-topic
66.3.2.1. 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.
66.3.2.2. Procedure for using the cluster CLI
-
Save the
slack-source-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the source by using the following command:
oc apply -f slack-source-binding.yaml
66.3.2.3. Procedure for using the Kamel CLI
Configure and run the source by using the following command:
kamel bind slack-source -p "source.channel=#myroom" -p "source.token=The Token" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic
This command creates the KameletBinding in the current namespace on the cluster.
