Dependencies At runtime, the insert-field-action Kamelet relies upon the presence of the following dependencies: github:openshift-integration.kamelet-catalog:camel-kamelets-utils:kamelet-catalog-1.6-SNAPSHOT camel:core camel:jackson camel:kamelet 29.3. Usage This section describes how you can use the insert-field-action . 29.3.1. Knative Action You can use the insert-field-action Kamelet as an intermediate step in a Knative binding. insert-field-action-binding.yaml apiVersion: camel.apache.org/v1alpha1 kind: KameletBinding metadata: name: insert-field-action-binding spec: source: ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: timer-source properties: message: '{"foo":"John"}' steps: - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: json-deserialize-action - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: insert-field-action properties: field: "The Field" value: "The Value" sink: ref: kind: Channel apiVersion: messaging.knative.dev/v1 name: mychannel 29.3.1.1. Prerequisite Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you're connected to. 29.3.1.2. Procedure for using the cluster CLI Save the insert-field-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 insert-field-action-binding.yaml 29.3.1.3. Procedure for using the Kamel CLI Configure and run the action by using the following command: kamel bind --name insert-field-action-binding timer-source?message='{"foo":"John"}' --step json-deserialize-action --step insert-field-action -p step-1.field='The Field' -p step-1.value='The Value' channel:mychannel This command creates the KameletBinding in the current namespace on the cluster. 29.3.2. Kafka Action You can use the insert-field-action Kamelet as an intermediate step in a Kafka binding. insert-field-action-binding.yaml apiVersion: camel.apache.org/v1alpha1 kind: KameletBinding metadata: name: insert-field-action-binding spec: source: ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: timer-source properties: message: '{"foo":"John"}' steps: - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: json-deserialize-action - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: insert-field-action properties: field: "The Field" value: "The Value" sink: ref: kind: KafkaTopic apiVersion: kafka.strimzi.io/v1beta1 name: my-topic 29.3.2.1. 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. 29.3.2.2. Procedure for using the cluster CLI Save the insert-field-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 insert-field-action-binding.yaml 29.3.2.3. Procedure for using the Kamel CLI Configure and run the action by using the following command: kamel bind --name insert-field-action-binding timer-source?message='{"foo":"John"}' --step json-deserialize-action --step insert-field-action -p step-1.field='The Field' -p step-1.value='The Value' kafka.strimzi.io/v1beta1:KafkaTopic:my-topic This command creates the KameletBinding in the current namespace on the cluster. 29.4.
