2.3.1.1. Prerequisite
Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.
2.3.1.2. Procedure for using the cluster CLI
-
Save the
avro-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 avro-deserialize-action-binding.yaml
2.3.1.3. Procedure for using the Kamel CLI
Configure and run the action by using the following command:
kamel bind --name avro-deserialize-action-binding timer-source?message='{"first":"Ada","last":"Lovelace"}' --step json-deserialize-action --step avro-serialize-action -p step-1.schema='{"type": "record", "namespace": "com.example", "name": "FullName", "fields": [{"name": "first", "type": "string"},{"name": "last", "type": "string"}]}' --step avro-deserialize-action -p step-2.schema='{"type": "record", "namespace": "com.example", "name": "FullName", "fields": [{"name": "first", "type": "string"},{"name": "last", "type": "string"}]}' --step json-serialize-action channel:mychannelThis command creates the KameletBinding in the current namespace on the cluster.
2.3.2. Kafka Action
You can use the avro-deserialize-action Kamelet as an intermediate step in a Kafka binding.

sink:
ref:
kind: KafkaTopic
apiVersion: kafka.strimzi.io/v1beta1

2.3.2.1. 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.
2.3.2.2. Procedure for using the cluster CLI
-
Save the
avro-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 avro-deserialize-action-binding.yaml
2.3.2.3. Procedure for using the Kamel CLI
Configure and run the action by using the following command:
kamel bind --name avro-deserialize-action-binding timer-source?message='{"first":"Ada","last":"Lovelace"}' --step json-deserialize-action --step avro-serialize-action -p step-1.schema='{"type": "record", "namespace": "com.example", "name": "FullName", "fields": [{"name": "first", "type": "string"},{"name": "last", "type": "string"}]}' --step avro-deserialize-action -p step-2.schema='{"type": "record", "namespace": "com.example", "name": "FullName", "fields": [{"name": "first", "type": "string"},{"name": "last", "type": "string"}]}' --step json-serialize-action kafka.strimzi.io/v1beta1:KafkaTopic:my-topicThis command creates the KameletBinding in the current namespace on the cluster.
