52.3. Usage

This section describes how you can use the slack-source.

52.3.1. 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

52.3.1.1. Prerequisite

Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.

52.3.1.2. Procedure for using the cluster CLI

Save the slack-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:
```
oc apply -f slack-source-binding.yaml
```

52.3.1.3. 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.

52.3.2. 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

52.3.2.1. 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.

52.3.2.2. Procedure for using the cluster CLI

Save the slack-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:
```
oc apply -f slack-source-binding.yaml
```

52.3.2.3. 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.
