1.2. 部署工作流

流程

1. 创建类似以下示例的工作流 YAML 文件：

   apiVersion: sonataflow.org/v1alpha08
   kind: SonataFlow
   metadata:
     name: greeting
     annotations:
       sonataflow.org/description: Greeting example on k8s!
       sonataflow.org/version: 0.0.1
   spec:
     flow:
       start: ChooseOnLanguage
       functions:
         - name: greetFunction
           type: custom
           operation: sysout
       states:
         - name: ChooseOnLanguage
           type: switch
           dataConditions:
             - condition: "${ .language == \"English\" }"
               transition: GreetInEnglish
             - condition: "${ .language == \"Spanish\" }"
               transition: GreetInSpanish
           defaultCondition: GreetInEnglish
         - name: GreetInEnglish
           type: inject
           data:
             greeting: "Hello from JSON Workflow, "
           transition: GreetPerson
         - name: GreetInSpanish
           type: inject
           data:
             greeting: "Saludos desde JSON Workflow, "
           transition: GreetPerson
         - name: GreetPerson
           type: operation
           actions:
             - name: greetAction
               functionRef:
                 refName: greetFunction
                 arguments:
                   message:  ".greeting+.name"
           end: true

2. 运行以下命令，将 SonataFlow 工作流定义应用到 OpenShift Container Platform 命名空间：

   $ oc apply -f <workflow-name>.yaml -n <your_namespace>

   greetings-workflow.yaml 文件的命令示例：

   $ oc apply -f greetings-workflow.yaml -n workflows

3. 运行以下命令列出所有构建配置：

   $ oc get buildconfigs -n workflows

4. 运行以下命令，获取构建过程的日志：

   $ oc logs buildconfig/<workflow-name> -n <your_namespace>

   greetings-workflow.yaml 文件的命令示例：

   $ oc logs buildconfig/greeting -n workflows

验证

1. 要验证部署，请运行以下命令列出所有 pod：

   $ oc get pods -n <your_namespace>

   确保与工作流对应的 pod 正在运行。

2. 运行以下命令，检查正在运行的 pod 及其日志：

   $ oc logs pod/<pod-name> -n workflows

流程

1. 创建类似以下示例的工作流 YAML 文件：

   apiVersion: sonataflow.org/v1alpha08
   kind: SonataFlow
   metadata:
     name: greeting
     annotations:
       sonataflow.org/description: Greeting example on k8s!
       sonataflow.org/version: 0.0.1
   spec:
     flow:
       start: ChooseOnLanguage
       functions:
         - name: greetFunction
           type: custom
           operation: sysout
       states:
         - name: ChooseOnLanguage
           type: switch
           dataConditions:
             - condition: "${ .language == \"English\" }"
               transition: GreetInEnglish
             - condition: "${ .language == \"Spanish\" }"
               transition: GreetInSpanish
           defaultCondition: GreetInEnglish
         - name: GreetInEnglish
           type: inject
           data:
             greeting: "Hello from JSON Workflow, "
           transition: GreetPerson
         - name: GreetInSpanish
           type: inject
           data:
             greeting: "Saludos desde JSON Workflow, "
           transition: GreetPerson
         - name: GreetPerson
           type: operation
           actions:
             - name: greetAction
               functionRef:
                 refName: greetFunction
                 arguments:
                   message:  ".greeting+.name"
           end: true

2. 运行以下命令，为工作流服务创建路由：

   $ oc expose svc/<workflow-service-name> -n workflows

   此命令创建用于访问工作流服务的公共 URL。

3. 运行以下命令，为公共 URL 设置环境变量：

   $ WORKFLOW_SVC=$(oc get route/<workflow-service-name> -n <namespace> --template='{{.spec.host}}')

4. 运行以下命令，向工作流发出 HTTP 调用，以将 POST 请求发送到服务：

   $ curl -X POST -H 'Content-Type: application/json' -H 'Accept: application/json' -d '{<"your": "json_payload">}' http://$WORKFLOW_SVC/<endpoint>

   输出示例

   {
     "id": "b5fbfaa3-b125-4e6c-9311-fe5a3577efdd",
     "workflowdata": {
       "name": "John",
       "language": "English",
       "greeting": "Hello from JSON Workflow, "
     }
   }

   此输出显示工作流正在运行时的预期响应示例。

流程

1. 运行以下命令，检查 SonataFlowBuild 实例是否存在：

   $ oc get sonataflowbuild <name> -n <namespace>

2. 运行以下命令来编辑 SonataFlowBuild 实例：

   $ oc edit sonataflowbuild/<name> -n <namespace>

   将 <name > 替换为 SonataFlowBuild 实例的名称，将 < namespace> 替换为部署了工作流的命名空间。

3. 添加 sonataflow.org/restartBuild: true 注解来重新启动构建。

   apiVersion: sonataflow.org/v1alpha08
   kind: SonataFlowBuild
   metadata:
     name: <name>
     annotations:
       sonataflow.org/restartBuild: true

   此操作会触发 OpenShift Serverless Logic Operator 来启动工作流的新构建。

4. 要监控构建过程，请运行以下命令来检查构建日志：

   $ oc logs buildconfig/<name> -n <namespace>

   将 <name > 替换为 SonataFlowBuild 实例的名称，将 < namespace> 替换为部署了工作流的命名空间。
