红帽全球峰会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.58.3. 使用方法
本节论述了如何使用 regex-router-action。
58.3.1. Knative Action
您可以在 Knative 绑定中使用 regex-router-action Kamelet 作为中间步骤。
regex-router-action-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: regex-router-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: regex-router-action
properties:
regex: "The Regex"
replacement: "The Replacement"
sink:
ref:
kind: Channel
apiVersion: messaging.knative.dev/v1
name: mychannel
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: regex-router-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: regex-router-action
properties:
regex: "The Regex"
replacement: "The Replacement"
sink:
ref:
kind: Channel
apiVersion: messaging.knative.dev/v1
name: mychannel58.3.1.1. 前提条件
确保已将 "Red Hat Integration - Camel K" 安装到您连接到的 OpenShift 集群中。
58.3.1.2. 使用集群 CLI 的步骤
-
将
regex-router-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 Clipboard Copied! Toggle word wrap Toggle overflow oc apply -f regex-router-action-binding.yaml
oc apply -f regex-router-action-binding.yaml
58.3.1.3. 使用 Kamel CLI 的步骤
使用以下命令配置并运行操作：
kamel bind timer-source?message=Hello --step regex-router-action -p "step-0.regex=The Regex" -p "step-0.replacement=The Replacement" channel:mychannel
kamel bind timer-source?message=Hello --step regex-router-action -p "step-0.regex=The Regex" -p "step-0.replacement=The Replacement" channel:mychannel此命令在集群的当前命名空间中创建 KameletBinding。
58.3.2. Kafka 操作
您可以在 Kafka 绑定中使用 regex-router-action Kamelet 作为中间步骤。
regex-router-action-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: regex-router-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: regex-router-action
properties:
regex: "The Regex"
replacement: "The Replacement"
sink:
ref:
kind: KafkaTopic
apiVersion: kafka.strimzi.io/v1beta1
name: my-topic
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: regex-router-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: regex-router-action
properties:
regex: "The Regex"
replacement: "The Replacement"
sink:
ref:
kind: KafkaTopic
apiVersion: kafka.strimzi.io/v1beta1
name: my-topic58.3.2.1. 先决条件
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。
58.3.2.2. 使用集群 CLI 的步骤
-
将
regex-router-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 Clipboard Copied! Toggle word wrap Toggle overflow oc apply -f regex-router-action-binding.yaml
oc apply -f regex-router-action-binding.yaml
58.3.2.3. 使用 Kamel CLI 的步骤
使用以下命令配置并运行操作：
kamel bind timer-source?message=Hello --step regex-router-action -p "step-0.regex=The Regex" -p "step-0.replacement=The Replacement" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic
kamel bind timer-source?message=Hello --step regex-router-action -p "step-0.regex=The Regex" -p "step-0.replacement=The Replacement" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic此命令在集群的当前命名空间中创建 KameletBinding。
