Chapter 66. Slack Source Receive messages from a Slack channel. 66.1. Configuration Options The following table summarizes the configuration options available for the slack-source Kamelet: Property Name Description Type Default Example channel * Channel The Slack channel to receive messages from string "#myroom" token * Token The token to access Slack. A Slack app is needed. This app needs to have channels:history and channels:read permissions. The Bot User OAuth Access Token is the kind of token needed. string Note Fields marked with an asterisk (*) are mandatory. 66.2. Dependencies At runtime, the slack-source Kamelet relies upon the presence of the following dependencies: camel:kamelet camel:slack camel:jackson 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.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 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.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 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. 66.4.
