Dependencies At runtime, the mask-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:jackson camel:kamelet camel:core 49.3. Usage This section describes how you can use the mask-field-action . 49.3.1. Knative Action You can use the mask-field-action Kamelet as an intermediate step in a Knative binding. mask-field-action-binding.yaml apiVersion: camel.apache.org/v1alpha1 kind: KameletBinding metadata: name: mask-field-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: mask-field-action properties: fields: "The Fields" replacement: "The Replacement" sink: ref: kind: Channel apiVersion: messaging.knative.dev/v1 name: mychannel 49.3.1.1. Prerequisite Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you're connected to. 49.3.1.2. Procedure for using the cluster CLI Save the mask-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 mask-field-action-binding.yaml 49.3.1.3. Procedure for using the Kamel CLI Configure and run the action by using the following command: kamel bind timer-source?message=Hello --step mask-field-action -p "step-0.fields=The Fields" -p "step-0.replacement=The Replacement" channel:mychannel This command creates the KameletBinding in the current namespace on the cluster. 49.3.2. Kafka Action You can use the mask-field-action Kamelet as an intermediate step in a Kafka binding. mask-field-action-binding.yaml apiVersion: camel.apache.org/v1alpha1 kind: KameletBinding metadata: name: mask-field-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: mask-field-action properties: fields: "The Fields" replacement: "The Replacement" sink: ref: kind: KafkaTopic apiVersion: kafka.strimzi.io/v1beta1 name: my-topic 49.3.2.1. 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. 49.3.2.2. Procedure for using the cluster CLI Save the mask-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 mask-field-action-binding.yaml 49.3.2.3. Procedure for using the Kamel CLI Configure and run the action by using the following command: kamel bind timer-source?message=Hello --step mask-field-action -p "step-0.fields=The Fields" -p "step-0.replacement=The Replacement" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic This command creates the KameletBinding in the current namespace on the cluster. 49.4.
