如何触发已有Argo CronWorkflow？Sensor触发报工作流不存在如何解决

错误根因 #

你使用的resubmit操作要求必须存在对应名称的已完成/运行中Workflow实例才能执行重新提交，你当前Sensor配置中仅声明了Workflow的基础元信息，不存在名为has-wf-full-refresh的真实Workflow实例，因此触发NotFound报错。

解决方案 #

你要实现事件驱动触发新的Workflow运行，不需要使用resubmit操作，改为create或者submit操作即可，无需修改原有CronWorkflow配置，两种适配方案如下：

方案1：直接引用现有CronWorkflow（推荐，适配批量场景） #

不需要复制工作流配置，直接引用已有的CronWorkflow资源触发运行，适合你有数百个现有CronWorkflow的场景，配置参考：

apiVersion: argoproj.io/v1alpha1
kind: Sensor
metadata:
  name: tibco-events-sensor
spec:
  template:
    metadata:
      annotations:
        sidecar.istio.io/inject: 'false'
    serviceAccountName: operate-workflow-sa
  dependencies:
    - name: tibco-dep
      eventSourceName: tibco-events-source
      eventName: whatever
  triggers:
    - template:
        name: has-wf-event-trigger
        argoWorkflow:
          group: argoproj.io
          version: v1alpha1
          resource: Workflow
          operation: submit
          metadata:
            generateName: has-wf-argo-events-
          source:
            cronWorkflow:
              # 替换为你现有CronWorkflow的名称和所在命名空间即可，无需修改原有CronWorkflow配置
              name: your-existing-cronworkflow-name
              namespace: your-workflow-namespace

方案2：复用工作流Spec配置 #

如果需要独立于原有CronWorkflow维护触发器的工作流配置，可以把原有CronWorkflow中的workflowSpec内容复制到Sensor配置中即可：

apiVersion: argoproj.io/v1alpha1
kind: Sensor
metadata:
  name: tibco-events-sensor
spec:
  template:
    metadata:
      annotations:
        sidecar.istio.io/inject: 'false'
    serviceAccountName: operate-workflow-sa
  dependencies:
    - name: tibco-dep
      eventSourceName: tibco-events-source
      eventName: whatever
  triggers:
    - template:
        name: has-wf-event-trigger
        argoWorkflow:
          group: argoproj.io
          version: v1alpha1
          resource: Workflow
          operation: create
          metadata:
            generateName: has-wf-argo-events-
          source:
            resource:
              apiVersion: argoproj.io/v1alpha1
              kind: Workflow
              metadata:
                generateName: has-wf-full-refresh-
              spec:
                # 直接粘贴原有CronWorkflow中spec.workflowSpec的全部内容即可
                entrypoint: main
                templates:
                  - name: main
                    container:
                      image: your-business-image
                      command: ["your-business-command"]

注意事项 #

• 确保operate-workflow-sa服务账号在对应命名空间下有创建Workflow、读取CronWorkflow的RBAC权限
• 配置生效验证无误后，即可停用原有CronWorkflow的定时规则，所有工作流将切换为事件驱动触发
