56.2. Dependencies
At runtime, the protobuf-deserialize-action Kamelet relies upon the presence of the following dependencies:
- github:openshift-integration.kamelet-catalog:camel-kamelets-utils:kamelet-catalog-1.6-SNAPSHOT
- camel:kamelet
- camel:core
- camel:jackson-protobuf
56.3. Usage
This section describes how you can use the protobuf-deserialize-action.
56.3.1. Knative Action
You can use the protobuf-deserialize-action Kamelet as an intermediate step in a Knative binding.
protobuf-deserialize-action-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: protobuf-deserialize-action-binding
spec:
source:
ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: timer-source
properties:
message: '{"first": "John", "last":"Doe"}'
steps:
- ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: json-deserialize-action
- ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: protobuf-serialize-action
properties:
schema: "message Person { required string first = 1; required string last = 2; }"
- ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: protobuf-deserialize-action
properties:
schema: "message Person { required string first = 1; required string last = 2; }"
sink:
ref:
kind: Channel
apiVersion: messaging.knative.dev/v1
name: mychannel
56.3.1.1. Prerequisite
Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.
56.3.1.2. Procedure for using the cluster CLI
-
Save the
protobuf-deserialize-action-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the action by using the following command:
oc apply -f protobuf-deserialize-action-binding.yaml
56.3.1.3. Procedure for using the Kamel CLI
Configure and run the action by using the following command:
kamel bind --name protobuf-deserialize-action-binding timer-source?message='{"first":"John","last":"Doe"}' --step json-deserialize-action --step protobuf-serialize-action -p step-1.schema='message Person { required string first = 1; required string last = 2; }' --step protobuf-deserialize-action -p step-2.schema='message Person { required string first = 1; required string last = 2; }' channel:mychannelThis command creates the KameletBinding in the current namespace on the cluster.
56.3.2. Kafka Action
You can use the protobuf-deserialize-action Kamelet as an intermediate step in a Kafka binding.
protobuf-deserialize-action-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: protobuf-deserialize-action-binding
spec:
source:
ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: timer-source
properties:
message: '{"first": "John", "last":"Doe"}'
steps:
- ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: json-deserialize-action
- ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: protobuf-serialize-action
properties:
schema: "message Person { required string first = 1; required string last = 2; }"
- ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: protobuf-deserialize-action
properties:
schema: "message Person { required string first = 1; required string last = 2; }"
sink:
ref:
kind: KafkaTopic
apiVersion: kafka.strimzi.io/v1beta1
name: my-topic
56.3.2.1. 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.
56.3.2.2. Procedure for using the cluster CLI
-
Save the
protobuf-deserialize-action-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the action by using the following command:
oc apply -f protobuf-deserialize-action-binding.yaml
56.3.2.3. Procedure for using the Kamel CLI
Configure and run the action by using the following command:
kamel bind --name protobuf-deserialize-action-binding timer-source?message='{"first":"John","last":"Doe"}' --step json-deserialize-action --step protobuf-serialize-action -p step-1.schema='message Person { required string first = 1; required string last = 2; }' --step protobuf-deserialize-action -p step-2.schema='message Person { required string first = 1; required string last = 2; }' kafka.strimzi.io/v1beta1:KafkaTopic:my-topicThis command creates the KameletBinding in the current namespace on the cluster.
