Chapter 43. Json Serialize Action Serialize payload to JSON 43.1. Configuration Options The json-serialize-action Kamelet does not specify any configuration option. 43.2. Dependencies At runtime, the json-serialize-action Kamelet relies upon the presence of the following dependencies: camel:kamelet camel:core camel:jackson 43.3. Usage This section describes how you can use the json-serialize-action . 43.3.1. Knative Action You can use the json-serialize-action Kamelet as an intermediate step in a Knative binding. json-serialize-action-binding.yaml apiVersion: camel.apache.org/v1alpha1 kind: KameletBinding metadata: name: json-serialize-action-binding spec: source: ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: timer-source properties: message: "Hello" steps: - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: json-serialize-action sink: ref: kind: Channel apiVersion: messaging.knative.dev/v1 name: mychannel 43.3.1.1. Prerequisite Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you're connected to. 43.3.1.2. Procedure for using the cluster CLI Save the json-serialize-action-binding.yaml file to your local drive, and then edit it as needed for your configuration. Run the action by using the following command: oc apply -f json-serialize-action-binding.yaml 43.3.1.3. Procedure for using the Kamel CLI Configure and run the action by using the following command: kamel bind timer-source?message=Hello --step json-serialize-action channel:mychannel This command creates the KameletBinding in the current namespace on the cluster. 43.3.2. Kafka Action You can use the json-serialize-action Kamelet as an intermediate step in a Kafka binding. json-serialize-action-binding.yaml apiVersion: camel.apache.org/v1alpha1 kind: KameletBinding metadata: name: json-serialize-action-binding spec: source: ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: timer-source properties: message: "Hello" steps: - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: json-serialize-action sink: ref: kind: KafkaTopic apiVersion: kafka.strimzi.io/v1beta1 name: my-topic 43.3.2.1. 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. 43.3.2.2. Procedure for using the cluster CLI Save the json-serialize-action-binding.yaml file to your local drive, and then edit it as needed for your configuration. Run the action by using the following command: oc apply -f json-serialize-action-binding.yaml 43.3.2.3. Procedure for using the Kamel CLI Configure and run the action by using the following command: kamel bind timer-source?message=Hello --step json-serialize-action kafka.strimzi.io/v1beta1:KafkaTopic:my-topic This command creates the KameletBinding in the current namespace on the cluster. 43.4.
