2.3. 使用方法
本节论述了如何使用 avro-deserialize-action
。
2.3.1. Knative 操作
您可以使用 avro-deserialize-action
Kamelet 作为 Knative 绑定中的中间步骤。
avro-deserialize-action-binding.yaml
apiVersion: camel.apache.org/v1alpha1 kind: KameletBinding metadata: name: avro-deserialize-action-binding spec: source: ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: timer-source properties: message: '{"first":"Ada","last":"Lovelace"}' steps: - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: json-deserialize-action - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: avro-serialize-action properties: schema: "{\"type\": \"record\", \"namespace\": \"com.example\", \"name\": \"FullName\", \"fields\": [{\"name\": \"first\", \"type\": \"string\"},{\"name\": \"last\", \"type\": \"string\"}]}" - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: avro-deserialize-action properties: schema: "{\"type\": \"record\", \"namespace\": \"com.example\", \"name\": \"FullName\", \"fields\": [{\"name\": \"first\", \"type\": \"string\"},{\"name\": \"last\", \"type\": \"string\"}]}" - ref: kind: Kamelet apiVersion: camel.apache.org/v1alpha1 name: json-serialize-action sink: ref: kind: Channel apiVersion: messaging.knative.dev/v1 name: mychannel
2.3.1.1. 前提条件
请确定您已将 "Red Hat Integration - Camel K" 安装到您连接的 OpenShift 集群中。
2.3.1.2. 使用集群 CLI 的步骤
-
将
avro-deserialize-action-binding.yaml
文件保存到您的本地驱动器中,然后根据需要编辑它。 使用以下命令运行操作:
oc apply -f avro-deserialize-action-binding.yaml
2.3.1.3. 使用 Kamel CLI 的步骤
使用以下命令配置并运行操作:
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:mychannel
这个命令会在集群的当前命名空间中创建 KameletBinding。
