Red Hat Camel K is deprecated
Red Hat Camel K is deprecated and the End of Life date for this product is June 30, 2025. For help migrating to the current go-to solution, Red Hat build of Apache Camel, see the Migration Guide.3.3. 使用方法
这部分论述了如何使用 avro-serialize-action
。
3.3.1. Knative Action
您可以在 Knative 绑定中使用 avro-serialize-action
Kamelet 作为中间步骤。
avro-serialize-action-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: avro-serialize-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\"}]}"

确保已将 "Red Hat Integration - Camel K" 安装到您连接到的 OpenShift 集群中。
3.3.1.2. 使用集群 CLI 的步骤
-
将
avro-serialize-action-binding.yaml
文件保存到本地驱动器中,然后根据需要编辑该文件。 使用以下命令运行操作:
Copy to clipboardCopiedoc apply -f avro-serialize-action-binding.yaml
3.3.1.3. 使用 Kamel CLI 的步骤
使用以下命令配置并运行操作:
kamel bind --name avro-serialize-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"}]}' channel:mychannel
Copy to clipboardCopied此命令在集群的当前命名空间中创建 KameletBinding。
3.3.2. Kafka 操作
您可以在 Kafka 绑定中使用 avro-serialize-action
Kamelet 作为中间步骤。
avro-serialize-action-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding

确保您已在 OpenShift 集群中安装了 AMQ Streams Operator,并在当前命名空间中创建一个名为 my-topic
的主题。另外,请确保已将 "Red Hat Integration - Camel K" 安装到您连接到的 OpenShift 集群中。
3.3.2.2. 使用集群 CLI 的步骤
-
将
avro-serialize-action-binding.yaml
文件保存到本地驱动器中,然后根据需要编辑该文件。 使用以下命令运行操作:
