45.1. Configuration Options 复制链接链接已复制到粘贴板!
The following table summarizes the configuration options available for the protobuf-deserialize-action
Kamelet:
Property | Name | Description | Type | Default | Example |
---|---|---|---|---|---|
schema * | Schema | The Protobuf schema to use during serialization (as single-line) | string |
|
Fields marked with an asterisk (*) are mandatory.
45.2. Dependencies 复制链接链接已复制到粘贴板!
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
45.3. Usage 复制链接链接已复制到粘贴板!
This section describes how you can use the protobuf-deserialize-action
.
45.3.1. Knative Action 复制链接链接已复制到粘贴板!
You can use the protobuf-deserialize-action
Kamelet as an intermediate step in a Knative binding.
protobuf-deserialize-action-binding.yaml
45.3.1.1. Prerequisite 复制链接链接已复制到粘贴板!
Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.
45.3.1.2. Procedure for using the cluster CLI 复制链接链接已复制到粘贴板!
-
Save the
protobuf-deserialize-action-binding.yaml
file 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
oc apply -f protobuf-deserialize-action-binding.yaml
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
45.3.1.3. Procedure for using the Kamel CLI 复制链接链接已复制到粘贴板!
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:mychannel
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:mychannel
This command creates the KameletBinding in the current namespace on the cluster.
45.3.2. Kafka Action 复制链接链接已复制到粘贴板!
You can use the protobuf-deserialize-action
Kamelet as an intermediate step in a Kafka binding.
protobuf-deserialize-action-binding.yaml
45.3.2.1. Prerequisites 复制链接链接已复制到粘贴板!
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.
45.3.2.2. Procedure for using the cluster CLI 复制链接链接已复制到粘贴板!
-
Save the
protobuf-deserialize-action-binding.yaml
file 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
oc apply -f protobuf-deserialize-action-binding.yaml
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
45.3.2.3. Procedure for using the Kamel CLI 复制链接链接已复制到粘贴板!
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-topic
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-topic
This command creates the KameletBinding in the current namespace on the cluster.
